Abstract in English:

ABSTRACT.- Souza M.F., Carvalho A.Q., Garino Jr F. & Riet-Correa F. 2011. [Caseous lymphadenitis in slaughtered hair sheep in northeastern Brazil.] Linfadenite caseosa em ovinos deslanados abatidos em um frigorífico da Paraíba. Pesquisa Veterinária Brasileira 31(3):224-230. Hospital Veterinário, CSTR, Universidade Federal de Campina Grande, Patos, PB 58700-000, Brazil. E-mail: franklin.riet@pq.cnpq.br The objective of this paper is to report the prevalence and distribution of lesions of caseous lymphadenitis (CL) in hair sheep slaughtered in an abattoir in the state of Paraíba, northeastern Brazil. From 1,466 sheep slaughtered, 236 (15.9%) had gross lesions similar to that of CL. The prevalence was higher in females, 17.9% (135/754), than in males, 13.8% (101/732). Ninety seven (36.3%) out of 268 lesions were localized in the prescapular lymph node, 22.4% (60/268) in the parotideal, and 20.9% (56/268) in the prefemoral. Only 70 (26.1%) out of 268 lesions suggestive of CL were detected during ante mortem examination. Caseous lymphadenitis-like lesions were observed in all flocks examined from different municipalities in the states of Paraíba, Pernambuco and Bahia. Cultures and histologic examination were performed in samples from 51 lesions. Corynebacterium pseudotuberculosis was isolated in 74.5% (43/51) samples, Staphylococcus aureus in 7.8% (4/51) samples, Escherichia coli in 2% (1/51), and in 5.9% (3/51) samples cultures were negative. Histologic findings in 11 lymph nodes showed all characteristic lesions of caseous lymphadenitis: central area of necrosis formed by concentric lamellae, with large bacterial colonies and mineralization, surrounded by an inflammatory exudate with epithelioid macrophages and few neutrophils; lymphocytes and plasma cells were observed in the next layer, and fibrous tissue was surrounding the whole lesion. Lesions in the other 32 lymph nodes showed most, but not all lesions characteristic of the disease. Giant cells were observed in 21 lymph nodes. Histologic lesions in lymph nodes from which S. aureus was isolated were similar as those of CL. These findings suggest that CL lesions are characteristic, but not pathognogmonic, because they can be confused with lesions caused by other pyogenic bacteria or tuberculosis; therefore bacteriologic examination is necessary for the diagnosis of the disease.

RESUMO.- Souza M.F., Carvalho A.Q., Garino Jr F. & Riet-Correa F. 2011. [Caseous lymphadenitis in slaughtered hair sheep in northeastern Brazil.] Linfadenite caseosa em ovinos deslanados abatidos em um frigorífico da Paraíba. Pesquisa Veterinária Brasileira 31(3):224-230. Hospital Veterinário, CSTR, Universidade Federal de Campina Grande, Patos, PB 58700-000, Brazil. E-mail: franklin.riet@pq.cnpq.br Este trabalho teve como objetivo determinar a prevalência e distribuição de lesões da linfadenite caseosa em ovinos deslanados abatidos no município de Mulungu, Paraíba. Dos 1466 ovinos abatidos, 236 (15,9%) apresentaram lesões macroscópicas semelhantes à linfadenite caseosa. A prevalência foi maior em fêmeas, 17.9% (135/754) que em machos, 13,8% (101/732). As principais lesões estavam localizadas nos linfonodos pré-escapulares em 36,3% (97/268) dos ovinos, nos parotídeos em 22,4% (60/268) e no pré-crural em 20,9% (56/268). Somente 70 (26,1%) de um total de 268 lesões foram detectadas no exame ante mortem. Foram encontradas lesões em todos os lotes provenientes de diversos municípios da Paraíba, Pernambuco e Bahia. Das 51 amostras em que foi feito o cultivo bacteriológico, em 74,5% (43/51) foi isolado Corynebacterium pseudotuberculosis. Em 7,8% (4/51) foi isolado Staphylococcus aureus, em 2% (1/51) Escherichia coli e 5,9% (3/51) amostras foram negativas. No exame histológico, em 11 linfonodos havia lesões da linfadenite caseosa caracterizadas por área de necrose central formada por lamelas concêntricas, com presença de grandes colônias bacterianas e focos de mineralização, rodeada por uma faixa de infiltrado inflamatório com macrófagos epitelióides e poucos neutrófilos. Na camada adjacente observaram-se linfócitos e plasmócitos e toda a lesão era delimitada por tecido conjuntivo fibroso. Nas outras 32 amostras foram observadas a maioria, mas não todas as lesões características da doença. Em 21 amostras foram encontradas células gigantes. As lesões histológicas dos linfonodos que foi isolado S. aureus foram semelhantes as da linfadenite caseosa. Conclui-se que as lesões histológicas de linfadenite caseosa são características, mas não patognomônicas, pois podem ser confundidas com lesões causadas por outros organismos piógenos e com tuberculose; portanto o isolamento bacteriológico é imprescindível para o diagnóstico definitivo da linfadenite caseosa.

#43 - Prevalence and geographical distribution of bovine eurytrematosis in cattle slaughtered in northern Paraná, Brazil

Abstract in English:

Azevedo J.R., Mannigel R.C., Agulhon A.Z., Borba T.R., Barbieri A.W., Oliveira D.C.L., Headley S.A. & Janeiro V. 2004. Prevalence and geographical distribution of bovine eurytrematosis in cattle slaughtered in northern Paraná, Brazil. Pesquisa Veterinária Brasileira, 24(1):23-26. Laboratório de Patologia Veterinária, Centro Universitário de Maringá, Av. Guedner 1610, Jd. Aclimação, Maringá, PR 87050-390, Brazil. E-mail: headleysa@cesumar.br A retrospective study of cattle slaughtered in northern Paraná during 2000 was performed to determine the prevalence and geographical distribution of bovine eurytrematosis (BE), as identified by the Federal Inspection Service (SIF). The cattle was from different regions of the State of Paraná; all regions had cattle parasitized by Eurytrema spp. BE was identified in 12.1% (12,534/103,411) of the total number of cattle inspected. Prevalence of animals parasitized by Eurytrema spp varied from 8.3% (Region G, São João do Caiuá, 1,069/12,914) to 40.5% (Region R, Ponta Grossa, 225/555). BE was more prevalent during the month of March (1.6) and markedly reduced during May (-2). A possible seasonal predominance of BE was identified: comparatively fewer cases occurred from April to August, while there was a peak from December to March. The study indicates that bovine eurytrematosis is hypoendemic and occurs in almost all geographical regions of the State of Paraná. The prevalence within this State is variable and may be directly related to factors of the biological cycle of the trematode, particularities of each region, and environmental conditions.

#44 - Seasonal fluctuation of Dermatobia hominis in bovine skins from a slaughterhouse, 20(4):151-154

Abstract in English:

ABSTRACT.- Brito L.G. & Moya Borja G.E. 2000. [Seasonal fluctuation of Dermatobia hominis in bovine skins from a slaughterhouse.] Flutuação sazonal de Dermatobia hominis em peles bovinas oriundas de matadouro. Pesquisa Veterinária Brasileira 20(4):151-154. Depto Parasitologia Animal, Univ. Fed. Rural do Rio de Janeiro, Seropédica, RJ 23851-970, Brazil The effect of temperature, rainfall and relative humidity on the seasonal fluctuation of Dermatobia hominis was investigated by counting the parasitized sidos of slaughtered cattle at the abattoir of Pirai county, in the state of Rio de Janeiro, Brazil, from November 1995 to October 1997. The higher incidence ofparasitized sidos was observed in November 1995 and December 1996. Secondary peaks were observed in March and May 1996 and March 1997. High percentage of parasitism in skins through the summer seasons was associated with mean temperatures of 25ºC and rainfall of 200 mm. The larval populations declined in both years from June to October, probably due to low temperatures at an average between 21 ºC and 22.SºC, and to Iow rainfall (under 50 mm). In a total of5,142 skins checked in the 2-year study, 2,710 sidos (52.7%) were parasitized with D. hominis larvae.

[Seasonal fluctuation of Dermatobia hominis in bovine skins from a slaughterhouse.] Flutuação sazonal de Dermatobia hominis em peles bovinas oriundas de matadouro. Pesquisa Veterinária Brasileira 20(4):151-154. Depto Parasitologia Animal, Univ. Fed. Rural do Rio de Janeiro, Seropédica, RJ 23851-970, Brazil. Realizou-se o estudo do efeito da temperatura, precipitação pluviométrica e da umidade relativa sobre a flutuação sazonal de larvas de Dermatobia hominis em 5.142 peles de bovinos. As peles foram obtidas junto a um matadouro localizado no município de Piraí, estado do Rio de Janeiro, Brasil, durante o período de novembro de 1995 a outubro de 1997. Os maiores picos de peles parasitadas por berne foram observados em novembro de 1995 e dezembro de 1996. Picos menores de infestação foram observados nos meses de março e maio de 1996 e março de 1997, quando também foram observadas altas porcentagens de peles infestadas. O aumento na porcentagem de peles parasitadas acompanhou o aumento da temperatura média mensal, sendo que temperaturas iguais ou maiores que 25ºC se mostraram benéficas ao aumento na porcentagem de peles parasitadas, assim como a precipitação pluviométrica, onde observou-se que períodos de chuvas mensais acima de 200mm³ favoreceram ao aumento da porcentagem de peles parasitadas. As menores porcentagens de peles parasitadas por berne foram observadas durante o período de junho a outubro de 1996 e de 1997, quando verificou-se temperaturas médias mensais variando entre 21 ºC e 22,5°C, sendo que estas não se mostraram favoráveis ao aumento na porcentagem de peles parasitadas, assim como, precipitações pluviométricas mensais menores que 50 mm³ Das 5.142 peles examinadas, 2.710 (52,7%) encontravam-se parasitadas pelo berne.


#45 - Salmonella serovars in meat of horses slaughtered in northeastern Brazil., 20(2):80-84

Abstract in English:

ABSTRACT.- Hofer E., Zamora M.R.N., Lopes A.E., Moura A.M.C:, Araújo H.L., Leite M.D.D. & Silva Filho S.J. 2000. [Salmonella serovars in meat of horses slaughtered in northeastern Brazil.] Sorovares de Salmonella. em carne de eqüídeos abatidos no nordeste do Brasil. Pesquisa Veterinária Brasileira 20(2):80-84. Depto Bacteriologia, Instituto Oswaldo Cruz/FIOCRUZ, Rio de janeiro, RJ 21045-900, Brazil. In the sixties and seventies there was an extraordinary increase in export of horse meat products to Europe andjapah. This favored an increase in risk of Salmonella outspread through those products to human and animal consumer populations. Thus, from an exporting company dealing with horse meat located in northeastern Brazil (state of Pernambuco), 19,238 fragments of more external muscles, Salmonella was isolated from 666 samples colleted from 433 animals (horses and donkeys). The serotyping of 745 isolates showed 98 serovars pertaining to 14 serogroups, predominantly classified into subspecies 1 (98.9%). S. Anatum, S. Carrau, S. Saintpaul, S. Agona, and S. Typhimurium were the most frequent serovars isolated. Preliminary data indicate that the primary causes for the presence of Salmonella in the meats probably was contact with feces from slaughtered animals, as well a.s possible contamination of environments, in view of the absence of human carriers researched in part of the personnel.

SINOPSE.- Hofer E., Zamora M.R.N., Lopes A.E., Moura A.M.C:, Araújo H.L., Leite M.D.D. & Silva Filho S.J. 2000. [Salmonella serovars in meat of horses slaughtered in northeastern Brazil.] Sorovares de Salmonella. em carne de eqüídeos abatidos no nordeste do Brasil. Pesquisa Veterinária Brasileira 20(2):80-84. Depto Bacteriologia, Instituto Oswaldo Cruz/FIOCRUZ, Rio de janeiro, RJ 21045-900, Brazil. Nas décadas de 60 e 70, houve um extraordinário incremento da exportação de produtos cárneos de equídeos dos países da América do Sul para a Europa e Japão. Este acontecimento favoreceu o aumento de risco da veiculação de Salmonella através desses produtos, para as populações humana e animal, consumidoras. Assim, num estabelecimento industrial e exportador de carne de eqüídeos localizado no nordeste do Brasil (Pernambuco), foram analisados bacteriologicamente, 19.238 fragmentos de músculos mais externos, que revelaram 666 exames positivos referentes a 433 animais (eqüinos e asininos) e resultando no isolamento de 745 cepas de Salmonella. Na amostragem foram·caracterizados do ponto de vista antigénico 98 sorovares, predominantemente classificados na subespécie 1 (98,9%) e tendo como os mais freqüentes S. Anatum, S. Carrau, S. Saintpaul, S. Agona e S. Typhimurium. Pelas análises efetuadas admite-se que as causas primordiais da presença de Salmonella nas carnes, provavelmente decorreu do contato com os excretas dos animais abatidos, bem como pela possível contaminação ambiental resultante, tendo em vista a ausência de portadores humanos, pesquisados numa parcela do pessoal.


#46 - Isolation of Chlamydia psittaci from water buffaloes slaughtered for consumption in Belém, Pará

Abstract in English:

A Chlamydia agent was isolated from 14 (70%) samples of organs and carcasses of slaughtered water buffaloes identified as Chlamydia by its morphological and staining characteristics, its pathogenic effect on chicken embryos. It was characterized as Chlamydia psittaci by the direct immunofluorescence test. In the isolation experiment, the serial passages system of inoculation from organs to the yolk sac of embryonated chicken was used, and 3 passages were made for each sample. The identification and characterization of isolates were made by the observation of typical cytoplasmatic inclusions in smears of the yolk sac membrane of embryos after inoculation and impressions of lesioned organs, stained by Giemsa, Macchiavello and Castañeda methods and by the fluorescence antibodies technique. Twenty samples of organs and carcass of water buffaloes that presented inflammation of the serosa in one or more of the lungs, liver and heart were studied. The lung was the organ with greatest number of isolates (8), followed by brain (6), liver (5) and heart (2). A significant correlation between the macroscopic lesions and the positive fluorescence of the agent in the correspondent inoculum was observed in the lung.

Abstract in Portuguese:

Um agente clamidiano foi isolado de 14 (70%) amostras de órgãos e carcaças de bubalinos abatidos para consumo e identificado como Chlamydia através de suas características morfológicas, tintorias e efeito patogênico para o embrião de galinha e caracterizado como Chlamydia psittaci no teste de imunofluorescência direta. No isolamento foi utilizado o sistema de passagens seriadas de inóculos de órgãos no saco vitelíno de ovos embrionados de galinha tendo sido executadas três passagens para cada amostra. A identificação e caracterização dos microrganismos isolados foi feita através de observação de inclusões citoplasmáticas típicas em esfregaços de membrana vitelina de ovos embrionados pós-inoculação e em impressões de órgãos lesados, corados pelo método de Giemsa, Macchiavello e Castañeda, e através do teste de imunofluorescência para Chlamydia psittaci. Foram estudadas 20 amostras de órgãos e carcaça de bubalinos que apresentavam processo de inflamação de serosa em um ou mais dos seguintes órgãos - pulmão, coração e fígado. O pulmão foi o órgão do qual se obteve maior número de isolados 8, seguido do cérebro, 6, fígado, 5 e coração 2. No caso do pulmão observou-se uma significativa correlação entre as lesões macroscópicas destes órgãos estudados e a imunofluorescência positiva para o agente, nos inóculos correspondentes.


#47 - Characteristics of the equine seasonal ovulatory curve. A study performed in slaughtered mares from southern Brazil

Abstract in English:

The ovaries of 1,374 mares collected at an abattoir were examined for gross evidence of ovulation such as hemorrhagic or luteal bodies. The exatninations were carried out from February 1984 to February 1985 in mares from the States of Rio Grande do Sul, Santa Catarina and Parana. The ovulatory rates observed for 1984 were 54.41% in February; 49.61% in March; 32,74% in April; 28.57% in May; 6.85% in June; 3.06% in July; 6.0% in August; 9.65% in September; 30.77% in October; 40.32% in November and 51.69% in December. In January and February of 1985 the ovulation rates observed were respectively 43.01 % and 43.48%. Of all ovulations 50.12% occurred in the right ovary and 49.88% in the left ovary. There was 6.97% of multiple ovulations.

Abstract in Portuguese:

Os ovários de 1374 éguas de abate, procedentes dos Estados do Rio Grande do Sul, Santa Catarina e Paraná, foram examinados no período de fevereiro de 1984 a fevereiro de 1985, verificando-se a presença de corpos hemorrágicos ou corpos lúteos, expressada em ovulações. Foi observada uma taxa de 54,41% de ovulações no mês de fevereiro de 1984; 49,61% em março; 32,74% em abril; 28,57% em maio; 6,85% em junho; 3,06% em julho; 6,0% em agosto; 9,65% em setembro; 30,77% em outubro; 40,32%; em novembro; 51,69% em dezembro; 43,01% em janeiro de 1985 e 43,48% em fevereiro. Do total de ovulações, 50,12% ocorreram no ovário direito e 49,88% no ovário esquerdo. Observou-se, ainda, um total de 6,97% de ovulações múltiplas.


#48 - Frequency of atrophic rhinitis in swine slaughtered in Santa Catarina, Brazil

Abstract in English:

Gross examination of the nasal structures of 1273 swine of various breeds, of both sexes, ra.hging in age from six to eight months, performed at slaughterhouses in the State of Santa Catarina, Brazil, showed that 300(23.6%) had turbinate atrophy or necrosis, lesions characteristic ofatrophic rhinitis. Seventy-five of these animals also showed deviation of the nasal septum. Twenty-three (2.4%) of the remaining 973 animals, without atrophic rhinitis, showed nasal septum deviation. A positive correlation (p < 0.01) was shown between the degree of turbina te atrophy and nasal septum deviation, demonstrated by an increase of 15 .9% as the severity oflesions increased. The frequency of atrophy of the turbinate banes varied from 18.0% to 48.9% in the principal swine producing regions of the state.

Abstract in Portuguese:

Exames morfológicos realizados à nível de matadouros, no Estado de Santa Catarina, das estruturas nasais de 1273 suínos de diferentes raças, de ambos os sexos e com idade variando entre 6 a 8 meses, revelaram que 300 (23,6%) deles tinham atrofia ou destruição dos cornetas, lesões características de rinite atrófica; 75 desses apresentaram adicionalmente desvio do septo nasal. Dos 973 animais restantes, sem rinite atrófica, 23 (2,4%) apresentavam desvio do septo nasal. Foi evidenciada uma correlação positiva entre o grau das lesões dos cornetas e o desvio do septo nasal, demonstrada pelo aumento em 15,9%, à medida que aumentava a severidade das lesões (P < 0,01). A freqüência de atrofia dos cornetas teve uma variação de 18,0 a 48,9% nas principais microrregiões produtoras de suínos do Estado.


#49 - Salmonellae from slaughtered pigs of Pará, Brazil

Abstract in English:

The bacteriological processing of the submandibular lymphnodés of 400 slaughtered pigs from 37 different rural holdings of 9 districts from the island Ilha do Marajó and nordeast of the state Para, Brazil, revealed the isolation of 51 (12,57%) salmonellae belonging to 6 serogroups and the following 10 serotypes: S. avonmouth 18 (35.29%), S. seremban 16 (31.37%), S. typhimurium 6 (11.76%), S. java and S. remo 3 (5.88%), and S. newport, S. miami, S. münster, S. oslo and S. tshiongwe once (1.96%). The most prevalent serotypes S. avonmouth and S. seremban found in this area were considered exotic types for pigs. The swine breeding in this area is very primitive and the pigs were of native type without a defined breed. The pigs are living free near the houses and on surrounding fields. The feed consisted mainly of plants, roots, fruits, insects, and other invertebrates found in the soH and·of the rest of slaughtered animals or cadavers found on the field.

Abstract in Portuguese:

O exame bacteriológico de linfonodos submandibulares de 400 suínos de abate oriundos de 37 propriedades de 9 municípios da Ilha de Marajá e da região nordeste do Estado do Pará, Brasil, revelou o isolamento de 51 (12,57%) salmonelas, pertencentes a seis sorogrupos e a 10 sorotipos, sendo 18 (35,29%) S. avonmouth, 16 (31,37%) S. seremban, 6 (11,76%) S. typhimurium, 3 (5,88%) S. java e S. remo, e uma (1,96%) S. newport, S. miami, S. münster, S. oslo e S. tshiongwe. Os sorotipos S. avonmouth e S. seremban, os mais prevalentes na região, são considerados exóticos para o suíno. A criação de suínos é primitiva, particularmente na Ilha de Marajó, onde os animais nativos, sem raça definida, sã9 criados soltos ao redor das residências e nos campos vizinhos. A principal alimentação consiste em plantas, raízes, frutas, insetos e outros invertebrados encontrados no solo e restos de animais abatidos ou cadáveres encontrados no campo.


#50 - Anomalies in the development of the tubular genital system of slaughtered female buffaloes (Bubalus bubalis)

Abstract in English:

Genital systems of 612 female water buffaloes (Bubalus bubalis Lin.) of undefined breed, obtained from slaughterhouses in the State of Para, were studied. A total of 77 (12.6%) animals showed abnormalities. Results from pregnant and non-pregnant animals were considered separately. In the oviducts of pregnant buffaloes, one case (1.3%) of unilateral segmentary aplasia was identified, while three similar cases (3.9%) were noted in non-pregnant buffaloes, as well as one case (1 .3%) with bilateral involvement. A large percentage (44.2%) of the findings were paraovarian cysts: 26 instances (33.8%) of unilateral paraovarian cysts were identified in the mesosalpinx, 11 (14.3%) corresponding to pregnant and 15 (19.5%) to non-pregnant females; eight bilateral cases (10.4%) were also observed, of which three (3.9%) were found in pregnant and five (6.5%) in non-pregnant buffaloes. In the uterus, out of a total of 29 (37.6%) anomalies, seven (9.1%) appeared in pregnant and 22 (28.5%) in non-pregnant buffaloes. A high prevalence (28.6%) of cystic formation on the perimetrium was observed in these animals. Malformations of the cervix were only found in three (3.9%) non-pregnant buffaloes. Two anomalies (2.6%) of the vagina were encountered in non-pregnant animals. Four (5.2%) anomalies were seen in the vestibule, one (1 .3%) in a pregnant animal and three (3.9%) in non-pregnant animals.

Abstract in Portuguese:

Foram estudados 612 sistemas genitais de búfalas (Bubalus bubalis Lin.) sem raça definida, provenientes de diferentes regiões do Estado do Pará e abatidas em matadouros, detectando-se anomalias em 77 (12,6%) delas. Os resultados foram considerados separadamente para animais gestantes e não gestantes. Nos oviductos de búfalas gestantes foi identificado um caso de aplasia segmentar unilateral (1,3%), enquanto em não gestantes foram assinalados três casos semelhantes (3,9%) e mais um caso bilateral (1,3%). No mesossalpinge, foram detectados 26 casos (33,8%) de cistos paraováricos unilaterais, sendo 11 (14,3%) em animais gestantes e 15 (19,5%) em não gestantes, além de oito (19,4%) casos bilaterais, sendo três (3,9%) em animais gestantes e cinco (6,5%) em não gestantes, perfazendo um total de 44,2% de cistos paraováricos nos achados. No útero foram verificadas 29 (37,6%) anomalias, sendo sete (9,1 %) em animais gestantes e 22 (28,5%) em não gestantes, com alta prevalência (28,6%) de formações císticas no perimétrio. Na cérvice foram encontradas três (3,9%) malformações em animais não gestantes. Na vagina foram encontradas duas (2,6%) anomalias em búfalas não gestantes, enquanto que no vestíbulo foram encontrados quatro (5,2%) casos, sendo um (1,3%) em búfala gestante e três (3,9%) em búfalas não gestantes.
