E-mail: fabioandre@fmvz.unesp.br The aim of this study was to evaluate by goniometry the hind limbs of pacas raised in captivity. Eight mature pacas (Cuniculus paca), three females and five males, weighing 6.0-8.2 kg, were used. The quantity of joint flexion and extension motion of the hip joint, stifle joint and tarsocrural joint was measured using a plastic standard goniometer. Under dissociative anesthesia, two measures were made for each member in each animal by the same observer at an interval of one week. There were no statistical differences of the quantity of joint motion between the moments. The flexion and extension angles varied from 1o to 5o in each moment for the same observer. The mean values of the angles of flexion and extension were, respectively, 43.96o±7.62 and 118.31o±9.79 for hip joint, 54.25o±10.24 and 131.53o±7.89 for stifle joint, and 45.94o±7.16 and 145.03o±5.06 for tarsocrural joint. Thus, it was observed that the range of motion of the pacas is greater in the tarsocrural joint, followed respectively by stifle and hip joints.

E-mail: fabioandre@fmvz.unesp.br O trabalho teve por objetivo avaliar por meio de estudos goniométricos os membros pélvicos de pacas criadas em cativeiro. Foram utilizadas oito pacas (Cuniculus paca), sendo três fêmeas e cinco machos, com peso entre 6,0 kg e 8,2 kg, nos quais foi aferido o movimento de extensão e flexão das articulações coxofemoral, joelho e tarsocrural utilizando-se um goniômetro de plástico. Foram realizadas duas aferições para cada membro pelo mesmo avaliador, com intervalo de uma semana entre cada aferição, com os animais sob anestesia dissociativa. Não houve diferença estatística nas aferições dos ângulos entres os momentos. As variações entre as medidas de flexão e extensão, efetuadas em cada momento pelo mesmo avaliador, foi entre 1o e 5o para cada membro. Os valores goniométricos médios foram: flexão de 43,96o±7,62 e extensão de 118,31o±9,79 para a articulação coxofemoral; flexão de 54,25o±10,24 e extensão 131,53o±7,89 para o joelho; flexão de 45,94o±7,16 e extensão de 145,03o±5,06 para a articulação tarsocrural. Sendo assim, observou-se que a amplitude de movimento das pacas é maior na articulação tarsocrural, seguida respectivamente do joelho e da articulação coxofemoral.

E-mail: joubertpimentel@bol.com.br Modern zoological gardens are institutions to wildlife maintenance, aiming its conservation, the performance of scientific research and leisure, recreation and environ-mental education activities. The variety of wild species living in conditions different from the one found in its natural habitats represents a propitious environment for diseases spread, specially the zoonotic ones. Due to data shortage and wild mammals’ epidemio-logical relevance both for toxoplasmosis as for leptospirosis, this study aimed to determine the serological survey of toxoplasmosis and leptospirosis in Neotropical wild mammals, from Zoo of Aracaju, Sergipe, Brazil. Blood samples were collected from 32 wild mammals, adults and from both sexes: 14 wild bearded capuchins (Cebus libidinosus), four golden-bellied capuchins (Cebus xanthosternus), three pumas (Puma concolor), one jaguar (Panthera onca), one crab-eating fox (Cerdocyon thous), six crab-eating raccoons (Procyon cancrivorus), two South American coatis (Nasua nasua), and one tayra (Eira barbara). Sera were tested to Toxoplasma gondii antibodies by the modified agglutination test (MAT e”1:25), and by the microscopic seroaglutination test (cut-off e”1:100) using 24 serovar of pathogenic leptospiras and two serovar of saprophyte leptospiras. Antibodies to T. gondii were found in 17 of 32 (53.1%) wild mammals, and antibodies to Leptospira spp. were found in 4 of 32 (12.5%) wild mammals. In relation to gender, 9 of 15 (60%) males, and 8 of 17 (47.1%) females had antibodies to Toxoplasma gondii, and 4 of 15 (26.7%) males had antibodies to Leptospira spp. Considering the origin of the seropositive animals to T. gondii, 8 of 17 (47%) were born in the zoo, 7 of 17 (41.2%) were from other zoos, and 2 (11.8%) were from the wild. Three of 4 (75%) mammals seropositive to Leptospira spp. were born in zoo, and 1 of 4 (25%) was from the wild. This is the first serological survey of Leptospira spp. in Neotropical primates and carnivores from Northeast zoo of Brazil, and the first time that antibodies to T. gondii and Leptospira spp. (serovar Copenhageni) were observed in the threaten specie of primate golden-bellied capuchins (Cebus xanthosternus) in Aracaju, SE.

E-mail: joubertpimentel@bol.com.br Os zoológicos modernos são instituições destinadas à manutenção da fauna selvagem com o objetivo de promover a conservação, pesquisa científica, lazer, recreação e educação ambiental. A ampla variedade de espécies selvagens, vivendo em condições diferentes do seu habitat natural, representa um ambiente propício à disseminação de doenças, muitas delas zoonóticas. Devido à escassez de dados e à relevância dos mamíferos selvagens neste contexto epidemiológico, tanto na toxoplasmose, quanto na leptospirose, foi efetuado o inquérito sorológico para toxoplasmose e leptospirose em mamíferos selvagens neotropicais do Zoológico de Aracaju, Sergipe, Brasil. Para tanto foram colhidas amostras sanguíneas de 32 animais, adultos, de ambos os sexos incluindo: 14 macacos-prego (Cebus libidinosus), quatro macacos-prego-do-peito-amarelo (Cebus xanthosternus), três onças-suçuaranas (Puma concolor), uma onça-pintada (Panthera onca), uma raposa (Cerdocyon thous), seis guaxinins (Procyon cancrivorus), dois quatis (Nasua nasua) e um papa-mel (Eira barbara). Para a pesquisa de anticorpos anti-Toxoplasma gondii foi utilizado o Teste de Aglutinação Modificada (MAT ³”1:25) e para pesquisa de anticorpos anti-Leptospira spp. foi utilizado o teste de Soroaglutinação Microscópica (ponto de corte ³1:100) com uma coleção de antígenos vivos que incluiu 24 variantes sorológicas de leptospiras patogênicas e duas leptospiras saprófitas. Dentre os 32 mamíferos, 17 (53,1%) apresentaram anticorpos anti-T. gondii e quatro (12,5%) foram positivos para anticorpos anti-Leptospira spp. De acordo com o sexo, 60% (9/15) dos machos e 47,1% (8/17) das fêmeas foram soropositivos para T. gondii e 26,7% (4/15) dos machos apresentaram anticorpos anti-Leptospira spp. Dos mamíferos que apresentaram anticorpos anti-T. gondii, 47% (8/17) nasceram no zoológico, 41,2% (7/17) foram oriundos de outras instituições e dois (11,8%) foram provenientes da natureza. Em relação aos quatro mamíferos soropositivos para Leptospira spp., três (75%) foram procedentes da natureza e um (25%) nasceu no zoológico. Este foi o primeiro inquérito sorológico de anticorpos anti-Leptospira spp. em primatas e carnívoros neotropicais em um zoológico do Nordeste do Brasil e descreveu pela primeira vez a ocorrência de anticorpos anti-T. gondii e anti-Leptospira spp. com sorovar mais provável Copenhageni no primata ameaçado de extinção macaco-prego-de-peito-amarelo (C. xanthosternus) em Aracaju, SE.

[Seroprevalence of bovine herpesvirus types 1 and/or 5 in the state of Rio Grande do Sul.] Soroprevalência de herpesvírus bovinos tipos 1 e/ou 5 no Estado do Rio Grande do Sul. Pesquisa Veterinária Brasileira 29(9):767-773. Instituto de Pesquisas Veterinárias Desidério Finamor, Fepagro Saúde Animal, Estrada do Conde 6000, Cx. Postal 47, Eldorado do Sul, RS 92990-000, Brazil. E-mail: proehe@gmail.com This study was carried out to estimate the prevalence of antibodies to bovine herpesviruses types 1(BoHV-1) and 5 (BoHV-5) in the state of Rio Grande do Sul (RS), Brazil, by testing serum samples against different BoHV-1 and BoHV-5 strains. The sera examined were obtained from a larger sample designed to estimate the prevalence of bovine brucellosis within the state. All sera were collected from cows 24 months or older, not vaccinated to bovine herpesviruses, from both dairy and beef herds. The number of samples to be tested was calculated based on an estimated prevalence of infection of 33%, with an average standard deviation of £1% and a 95% limit of agreement. Sera from 2.200 cattle from 390 farms distributed in 158 counties were tested by serum neutralization (SN) tests in search for antibodies to the following strains: BoHV-1.1 (strains EVI123/98 and Los Angeles), BoHV-5a (strain EVI88/95) and BoHV-5b (strain A663). The overall seroprevalence to BoHV-1 and BoHV-5 in the sampled herds was 29.2% (642/2.200); seropositive animals were detected in 225 (57.7%) of the sampled farms. Prevalence estimates varied according to the virus used for challenge in SN tests. The highest prevalence and sensitivity were attained when positive SN results against the four different strains were added together. The use of only one virus for challenge in SN tests would lead to a loss in sensitivity from 20.4% to 34.6% when compared to the combined SN-positive results. These findings provide evidence that antibodies to BoHV-1 and BoHV-5 are largely spread in dairy and beef herds in RS, although prevalence in distinct geographic regions is quite variable. The results were strongly affected by the virus strains used for challenge in SN testing. This must be taken into account when performing serologic tests to detect BoHV-1 and BoHV-5 antibodies. As SN test is not capable of discriminating between antibody responses to BoHV-1 and BoHV-5, type-specific prevalence remains unknown.

Postal 47, Eldorado do Sul, RS 92990-000, Brazil. E-mail: proehe@gmail.com Este estudo objetivou estimar a prevalência de anticorpos contra os herpesvírus bovinos tipos 1 e 5 (BoHV-1 e BoHV-5) no Estado do Rio Grande do Sul (RS), Brasil, frente a diferentes cepas de BoHV-1 e BoHV-5. As amostras de soro utilizadas foram extraídas de uma amostragem mais ampla, desenhada para estimar a prevalência de brucelose bovina no Estado. Todos os soros foram coletados de vacas com idade igual ou superior a 24 meses de idade, não vacinadas contra herpesvírus bovinos, de rebanhos de corte e leite. O cálculo amostral foi baseado em uma expectativa de prevalência média de infecção de 33%, considerando-se um erro padrão não superior a 1% e um intervalo de confiança de 95%. Com base nesse cálculo foram examinados 2.200 soros, provenientes de 390 propriedades e 158 municípios. Os soros foram analisados na busca de anticorpos contra BoHV-1 e BoHV-5 pela técnica de soroneutralização (SN), executada frente a quatro cepas de vírus distintas: EVI123/98 e Los Angeles (BoHV-1.1); EVI88/95 (BoHV-5a) e A663 (BoHV-5b). A prevalência média de anticorpos contra o BoHV-1 e BoHV-5 nos animais amostrados foi de 29,2% (642/2200); animais soropositivos foram identificados em 57,7% (225/390) dos rebanhos. As estimativas de prevalência variaram de acordo com a cepa e/ou vírus utilizado para o desafio nos testes de SN. A prevalência e a sensibilidade mais altas foram obtidas quando os resultados positivos à SN frente aos quatro vírus distintos foram somados. O uso de somente um vírus de desafio na SN levaria a redução de sensibilidade de 20,4% a 34,6% quando comparada com os resultados positivos combinados. Estes achados evidenciam que anticorpos contra BoHV-1 e BoHV-5 estão amplamente difundidos nos rebanhos do RS, embora a prevalência em distintas regiões geográficas seja bastante variada. Os resultados obtidos nas estimativas de prevalência foram fortemente afetados pelas diferentes amostras de vírus usadas nos testes de SN. Esse fato deve ser levado em consideração quando estudos sorológicos para BoHV-1 e BoHV-5 forem realizados. Como a SN não é capaz de discriminar as respostas de anticorpos para BoHV-1 e BoHV-5, a prevalência tipo-específica permanece desconhecida.

E-mail: hermann@ioc.fiocruz.br In the present study we investigated the presence of infections by vaccinia-like viruses in dairy cattle from 12 counties in the state of Rio de Janeiro in the last 9 years. Clinical specimens were collected from adult animals with vesicular/pustular lesions mainly in the udder and teats, and from calves with lesions around the nose and mouth. A plaque reduction neutralization test (PRNT) was applied to search for antibodies to Orthopoxvirus; the vesicular/pustular fluids and scabs were examined by PCR, electron microscopy (EM) and by inoculation in VERO cells for virus isolation. Antibodies to Orthopoxvirus were detected in most cases. The PCR test indicated a high nucleotide homology among the isolates and the vaccinia viruses (VACV) used as controls. By EM, typical orthopoxvirus particles were observed in some specimens. The agents isolated in tissue culture were confirmed as vaccinia-like viruses by EM and PCR. The HA gene of the vaccinia-like Cantagalo/IOC virus isolated in our laboratory was sequenced and compared with other vaccinia-like isolates, showing high homology with the original Cantagalo strain, both strains isolated in 1999 from dairy cattle. Antibodies to Orthopoxvirus were detected in one wild rodent (genus Akodon sp.) collected in the northwestern region of the state, indicating the circulation of poxvirus in this area. Nonetheless, PCR applied to tissue samples collected from the wild rodents were negative. Vesicular/pustular lesions in people in close contact with animals have been also recorded. Thus, the vaccinia-like virus infections in cattle and humans in the state seem to be an expanding condition, resulting in economic losses to dairy herds and leading to transient incapacitating human disease. Therefore, a possible immunization of the dairy cattle in the state should be carefully evaluated.

E-mail: jrmodolo@fmvz.unesp.br In order to assess the frequency of dairy goats seropositive for Neospora caninum in the state of São Paulo, and its relationship with age, sex, presence of dogs and reproductive problems in goat pens, serum samples were obtained from 923 goats of both sexes older than 3 months of age. Samples were collected in 17 properties located in different municipalities. Neospora agglutination test (NATe”25) was used to determine the presence of Neospora caninum in all animals. Epidemiological and reproductive data were obtained through a questionnaire which was administered in all goat pens. Significance level was set at 5% for all statistical tests. N. caninum positivity rate was 19.77%. Only one of the properties had no seropositive animal revealing N. caninum diffusion in the state. Seropositivity frequency did not correlate with sex, age, or reproductive problems. However, the presence of dogs was associated with a higher frequency of N. caninum seropositivity. A choroplethic map with hatch patterns showing the geographical distribution of goats seropositive for Neospora caninum may considerably contribute to geographic epidemiological studies and the development of disease control strategies.

Samples were collected in 17 properties located in different municipalities. Neospora agglutination test (NATe”25) was used to determine the presence of Neospora caninum in all animals. Epidemiological and reproductive data were obtained through a questionnaire which was administered in all goat pens. Significance level was set at 5% for all statistical tests. N. caninum positivity rate was 19.77%. Only one of the properties had no seropositive animal revealing N. caninum diffusion in the state. Seropositivity frequency did not correlate with sex, age, or reproductive problems. However, the presence of dogs was associated with a higher frequency of N. caninum seropositivity. A choroplethic map with hatch patterns showing the geographical distribution of goats seropositive for Neospora caninum may considerably contribute to geographic epidemiological studies and the development of disease control strategies.

E-mail: jrmodolo@fmvz.unesp.br The study evaluated the anti-Toxplasma gondii antibodies occurrence in dairy goats in São Paulo State, and also verified likely associations with age, sex, presence of cats, occurrence of reproductive problems, and potential risks to public health. Serum was obtained from 923 animals of both sex, over three months of age from 17 properties in different cities. For the diagnosis, the indirect immunofluorescence reaction (RIFIe”16) and a questionnaire about health to collect epidemiological information and the reproductive cycle of every goat were used. Among all properties, 15 foci of T. gondii were diagnosed with seropositivity ranging from 2.70% to 81.25%. Neither association between the frequency of seropositivity and the sex of animals nor occurrence of reproduction failure of goats was identified. There was positive influence of anti-T. gondii antibody rate due to the older age of the animals and the presence of cats in pens. The risk of transmitting T. gondii to the public health must be considered, once in some properties where the positive serology was verified natural, products such as milk and/or meat are commercialized. Results were discussed at 5% level of significance.

E-mail: proehe@ufrgs.br The results of 23 years of rabies diagnosis carried out at the Veterinary Research Institute Desidério Finamor, in the state of Rio Grande do Sul, RS, Brazil, are reported. From 1985 to 2007, a total of 23.460 specimens were examined, corresponding to 95% of the total number of samples submitted to rabies laboratory diagnosis notified within the state. Diagnostic methods included standard techniques such as the fluorescent antibody test (FAT) and mouse inoculation test (MIT). No cases of human rabies occurred in the period. Rabies virus (RV) was detected in 739 specimens (3.1%), from which 656 (88.7%) were from cattle. The virus was also identified in specimens from 23 dogs (3.1%), 21 horses (2.9%), 29 bats (4.0%), 4 cats (0.5%), 3 sheep (0.4%), 2 pigs (0.27%) and a wild animal of undetermined species (0.13%). The last case of rabies associated with a canine variant was diagnosed in 1988. Two cases of rabies associated with bat variant viruses were reported, in a domestic cat (2001) and in a dog (2007). In cattle, a marked tendency to a decrease in the number of cases was detected in the examined period. In contrast, an increase in the number of cases in haematophagous as well as in non haematophagous bats is noticed. However, as the number of bat specimens submitted for diagnosis has increased, this finding most likely reflects a higher degree of awareness on the possible role for bats in the rabies transmission cycle, rather than any particular changes on the virus or its hosts.

E-mail: magblagitz@usp.br The aim was to evaluate and compare the microbiological and cellular profile of the milk of Santa Ines ewes during the lactation period and the active involution. Milk samples were analyzed from 12 ewes during these distinct periods. Clinical examination of the mammary gland, somatic cell count (SCC), California Mastitis Test (CMT), bacteriologic screening and sensibility of the pathogens in vitro were performed. Most alterations were observed in the active involution period. SCC and CMT were higher in this same period. Besides this, a high persistency of infection occurred. The active involution period did not show high susceptibility. Coagulase-negative staphylococci were the only isolated bacteria. A high antimicrobial sensibility of these pathogens was also encountered.
