Abstract in English:

Abamectin is an anthelminthic widely used in agriculture, human, and veterinary medicine. The predomination in cases of abamectin toxicosis are neurological changes such as ataxia, lethargy, coma, tremors, convulsions, mydriasis, and blindness. This article describes the clinical, morphological, and toxicological results of cattle accidentally poisoned by abamectin on properties in the states of Rondônia and Mato Grosso, Brazil. Clinical and epidemiological data on the affected herd were collected from the owners, employees, and veterinarians of the properties. A clinical examination was conducted, and a necropsy was performed on the affected animals, with organ samples collected for histological and toxicological analysis. The main clinical signs observed were ataxia, apathy, and death. No significant gross or histologic changes were present. The concentration of abamectin in the brains and livers was > 25.00 μg/kg. The predisposing factors for the occurrence of these outbreaks were visual estimation of cattle weight, standardization of medication doses for batches of cattle, and medication bottle error during application resulting in poisoning and death of cattle. The findings emphasize the need to improve animal management and team training prior to drug application in properties.

Abstract in English:

Mammary neoplasms are common in domestic felines but are rarely reported in wild felids. On the other hand, understanding the diseases that affect these animals is crucial, considering the importance of wild felines for the environmental balance. Therefore, we aim to describe a case of mammary neoplasia in an ocelot (Leopardus pardalis). A 12-year-old female ocelot housed in a breeding facility located in the state of Paraíba, Brazil, presented anorexia and dehydration for 48 hours, followed by death. The necropsy revealed a firm mass in the abdominal region and a single irregular, ulcerated mass between the caudal abdominal and inguinal mammary glands. All lesions were located on the right side. The masses were multilobulated, irregular, soft, and white on sectioning, with friable and dark (necrotic) areas. Histopathological examination revealed multiple multilobulated, partially encapsulated, non-delimited masses without free borders, composed of ducts, sometimes forming densely solid areas. Metastases were also observed in the lung and the internal muscle of the pelvic limb in the femoral region. Immunohistochemistry (IHC) was performed using anti-cytokeratin and anti-vimentin antibodies. IHC revealed cytokeratin positivity in the mammary gland. Vimentin was negative in the neoplastic cells and positive in the adjacent connective tissue. Thus, histopathological examination led to what seems to be the first diagnosis of metastatic simple tubular mammary carcinoma in an ocelot.

Abstract in Portuguese:

Neoplasia mamárias são comuns em felinos domésticos, porém pouco relatadas em felídeos selvagens. Por outro lado, considerando a importância do felinos silvestres para o equilíbrio ambiental, torna-se fundamental o conhecimento das enfermidades que acometem esses animais. Dessa forma, objetivamos descrever um caso de neoplasia mamária em uma jaguatirica (Leopardus pardalis). Uma Jaguatirica fêmea, de 12 anos, mantida em um criatório situado no estado da Paraíba, Brasil, apresentou quadro de inapetência e desidratação por 48 horas, seguido de morte. Após a morte foi realizada a necropsia, na qual foi possível observar uma massa firme na região abdominal e uma massa única irregular e ulcerada entre a mama abdominal caudal e inguinal. Todas as lesões situavam-se no lado direito. Ao corte essas massas eram multilobuladas, irregulares, macias e brancas, com áreas friáveis e escuras (necróticas). No exame histopatológico foram visualizadas múltiplas massas multilobuladas, parcialmente encapsuladas, não delimitadas, sem bordas livres, constituídas por ductos, por vezes, formando áreas densamente sólidas. Metástases também foram observadas no pulmão e no músculo interno do membro pélvico na região do fêmur. A imuno-histoquímica (IHQ) foi com anticorpos anti-citoceratina e anti-vimentina. A IHQ revelou positividade para a citoceratina na glândula mamária. A vimentina foi negativa nas células neoplásicas e positivas no tecido conjuntivo adjacente. Assim, o exame histopatológico conduziu ao que parece ser o primeiro diagnóstico de carcinoma mamário tubular simples metastático em uma jaguatirica.

Abstract in English:

Bovine mastitis is the most common infectious disease in dairy herds and causes important economic losses. Various pathogens can cause the disease, with Staphylococcus aureus being one of the most significant. S. aureus can cause clinical, subclinical, and chronic forms of the disease due to a variety of virulence factors, including protein A, coagulase, toxins, and adhesins. The presence of methicillin-resistant S. aureus strains complicates treatment protocols and raises concerns about antimicrobial resistance. The genetic characterization of these strains, utilizing techniques such as molecular typing by pulsed-field gel electrophoresis (PFGE), reveals the existence of different genetic and virulence profiles, as well as the geographical variations in the distribution of these genotypes. The role of next-generation sequencing (NGS) technologies, functional genomics, and multi-omics approaches in the genetic research of bovine mastitis are highlighted, providing a complete understanding of its genetic basis and opening opportunities for targeted interventions and improved disease control strategies in the dairy industry. This review highlights the importance of understanding the genetic diversity and pathogenic mechanisms of S. aureus in bovine mastitis to develop effective disease management strategies and reduce economic losses in the dairy sector globally.

Abstract in Portuguese:

A mastite bovina é a doença infecciosa mais comum em rebanhos leiteiros e causa importantes perdas econômicas. Diversos patógenos podem causar a doença, sendo Staphylococcus aureus um dos mais significativos. S. aureus pode causar formas clínicas, subclínicas e crônicas da doença devido a uma variedade de fatores de virulência, incluindo proteína A, coagulase, toxinas e adesinas. A presença de cepas de S. aureus resistentes à meticilina complica os protocolos de tratamento e levanta preocupações sobre a resistência antimicrobiana. A caracterização genética dessas cepas, utilizando técnicas como a tipagem molecular por eletroforese em gel de campo pulsado (PFGE), revela a existência de diferentes perfis genéticos e de virulência, bem como as variações geográficas na distribuição desses genótipos. Destaca-se o papel das tecnologias de sequenciamento de nova geração (NGS), da genômica funcional e das abordagens multi-ômicas na pesquisa genética da mastite bovina, proporcionando uma compreensão mais completa de sua base genética e abrindo oportunidades para intervenções direcionadas e melhores estratégias de controle da doença na indústria de laticínios. Esta revisão destaca a importância de compreender a diversidade genética e os mecanismos patogênicos de S. aureus na mastite bovina para desenvolver estratégias eficazes de manejo da doença e reduzir as perdas econômicas no setor de laticínios globalmente.

Abstract in English:

Salivary gland neoplasms are infrequently documented in veterinary medicine and rare in non-human primates; therefore, they are scarce in the literature. Adenocarcinomas are malignant neoplasms that originate in the glandular epithelium and can affect various species. Our study presents detailed cytological, histological, and immunohistochemical findings of a salivary gland adenocarcinoma in a capuchin monkey (Sapajus nigritus). In the necropsy, a multilobulated mass was observed in the left submandibular region, characterized by a dark red surface, soft and firm upon cut surface. Histologically, a neoplastic proliferation of malignant epithelial cells was identified in the submandibular region and the lungs. The cells showed acinar formation, areas of architectural tissue differentiation loss, and solid aggregates. Immunohistochemistry was conducted to corroborate and elucidate the case. In the neoplasia, there was positive immunolabelling for pan-cytokeratin (Pan CK) and cytokeratin 7 (CK7), and negative labeling for thyroglobulin, thyroid transcription factor-1 (TTF-1), cytokeratin 20 (CK20), and Napsin A. The cytological, anatomopathological, and immunohistochemical findings lead to the diagnosis of salivary gland adenocarcinoma. Remarkably, this report seems to be the inaugural documentation of this neoplasm in a capuchin monkey (Sapajus nigritus).

Neoplasias de glândula salivar são pouco documentadas na medicina veterinária e raras em primatas não-humanos, portanto são escassos na literatura. Adenocarcinomas são neoplasias malignas que se originam do epitélio glandular e podem afetar várias espécies. Nosso estudo apresenta achados citológicos, histológicos e imuno-histoquímicos de um adenocarcinoma de glândula salivar em macaco-prego (Sapajus nigritus). Na necropsia, foi observada uma massa multilobulada na região submandibular esquerda, caracterizada por uma superfície vermelha escura e macia a firme ao corte. Histologicamente, uma proliferação neoplásica de células epiteliais malignas foi identificada na região submandibular e nos pulmões. As células apresentaram formação acinar, áreas com perda de diferenciação tecidual e agregados sólidos. Foi realizado imuno-histoquímica para corroborar e elucidar o caso. Houve imunomarcação positiva para citoqueratina (Pan CK) e citoqueratina 7 (CK7), e marcação negativa para tireoglobulina, fator de transcrição de tireoide-1 (TTF-1), citoqueratina 20 (CK20) e Napsin A. Os achados citológicos, anatomopatológicos e imuno-histoquímicos levam ao diagnóstico de adenocarcinoma de glândula salivar. Este relato apresenta um caso que parece ser inédito desta neoplasia em um macaco-prego (Sapajus nigritus).

Abstract in English:

Blood samples were taken from 94 dairy cows based on a past of abortions (4th-7th months) in four different farms in Burdur province. The presence of Chlamydophila abortus (Antibody = Ab), Coxiella burnetti (Ab), Sarcocystis spp. (Ab), Neospora caninum (Ab) and bovine viral diarrhea virus (BVDV) (Antigen = Ag) were investigated in the collected blood samples. While seropositivity was determined for C. abortus, C. burnetti and N. caninum in the samples, BVDV was detected positive in the same samples. No samples were detected seropositive for Sarcocystis spp. (Ab). N. caninum showed the highest seropositivity in the samples tested, whereas C. burnetti had the lowest. When we looked at the mixed distribution of the factors in the positive animals, C. abortus + N. caninum was found to be the highest, and C. burnetti + N. caninum was the lowest. As a result of the study, it was determined that N. caninum was the most common abortion factor in cattle that had abortions between 4-7 months, and BVDV, C. abortus and C. burnetti, respectively, could also cause abortion. The high level of N. caninum indicates that canes and underground spring waters around the farms may be important reservoirs.

Abstract in English:

Botulism is a serious disease caused by neurotoxins produced by Clostridium botulinum, an anaerobic spore-forming bacterium commonly found in the environment and the intestinal tract of animals. The disease occurs through the ingestion of food or water contaminated with preformed toxins, leading to progressive flaccid paralysis across various susceptible species. This study reports the clinical, epidemiological, and laboratory aspects of the simultaneous occurrence of type C botulism in domestic birds (chickens and ducks) and dogs on a farm in Rio Pomba, Minas Gerais, Brazil. The farm housed 47 chickens, two ducks, and seven dogs. Over approximately 15 days, 40 chickens (85.1%) and one duck (50%) fell ill and died. Among the seven dogs, five (71.4%) exhibited clinical signs, and two (28.6%) ultimately died. Diagnosis of botulism was confirmed through bioassay technique and neutralization using homologous antitoxin in mice, which identified botulinum toxin type C in serum samples from two chickens with clinical signs, in samples from two necropsied chickens and in one water sample. The most probable transmission route was likely the remains of a decomposing bovine carcass, and the water that had accumulated around it, to which the chickens, ducks and dogs had access, highlighting the importance of proper carcass disposal to prevent disease outbreaks.

Abstract in Portuguese:

Botulismo é uma doença grave causada por neurotoxinas produzidas por Clostridium botulinum, uma bactéria anaeróbica formadora de esporos comumente encontrada no ambiente e trato intestinal de animais. A doença ocorre pela ingestão de alimentos ou água contaminados com toxinas pré-formadas, levando à paralisia flácida progressiva em várias espécies suscetíveis. Este estudo relata os aspectos clínicos, epidemiológicos e laboratoriais de um surto de botulismo tipo C que afetou aves domésticas (galinhas e patos) e cães em uma fazenda no município de Rio Pomba, Minas Gerais, Brasil. A fazenda abrigava 47 galinhas, dois patos e sete cães. Ao longo de aproximadamente 15 dias, 40 galinhas (85,1%) e um pato (50%) adoeceram e morreram. Entre os sete cães, cinco (71,4%) apresentaram sinais clínicos e dois (28,6%) acabaram morrendo. O diagnóstico de botulismo foi confirmado por meio da técnica de bioensaio e neutralização com antitoxina homóloga em camundongos, que identificou toxina botulínica tipo C em amostras de soro de duas galinhas com sinais clínicos, em amostras de duas galinhas necropsiadas e em uma amostra de água. A rota de transmissão mais provável foi provavelmente os restos de uma carcaça bovina em decomposição e a água que havia se acumulado ao redor dela, à qual as galinhas, patos e cães tiveram acesso, o que destaca a importância do descarte adequado de carcaças para prevenir surtos da doença.

Abstract in English:

Feline obesity has become an increasingly common problem worldwide over the past decade. Excess weight in cats may predispose them to a range of conditions such as insulin resistance, type 2 diabetes mellitus, and hepatic lipidosis. However, few studies have conducted clinical-laboratory profiles of overweight and obese cats. Therefore, the aim of this study was to describe and correlate clinical and laboratory alterations in overweight and obese cats, comparing them with lean cats. Fifty-three cats were evaluated and divided into obese (OB), overweight (SP), and control (CT) groups. After a clinical assessment, the clinically selected cats underwent morphometric measurements and hematological and biochemical tests; their owners were also instructed to complete a questionnaire. Our primary findings included an increase in mean corpuscular volume and total proteins, a decrease in red blood cell count, and an increase in circulating concentrations of total cholesterol, triglycerides, and urea in the OB group; the SP group exhibited an increase only in total cholesterol and urea. Furthermore, the OB and SP groups exhibited a higher frequency of ad libitum feeding, were more likely to receive premium food, and generally had lower activity levels. We concluded that being overweight or obese altered the cats’ hematological and biochemical parameters. Moreover, factors related to the feeding and environmental management of cats may predict an increased risk of being overweight.

Abstract in Portuguese:

Em gatos, a obesidade tornou-se um problema global com prevalência crescente nos últimos 10 anos. O excesso de peso na espécie felina pode predispor a uma série de condições como a resistência à insulina, a diabetes mellitus tipo 2 e a lipidose hepática. Poucos estudos traçaram um perfil clínico-laboratorial de gatos com sobrepeso e obesos. Com isso, o objetivo deste trabalho foi descrever e correlacionar as alterações clínicas e laboratoriais em gatos com sobrepeso e obesos comparando-as com gatos magros. Foram avaliados 53 gatos, divididos nos grupos: obeso (OB), sobrepeso (SP) e controle (CT). Após realizar uma avaliação clínica, os gatos clinicamente selecionados foram direcionados para mensuração de medidas morfométricas, coleta de exames hematológicos e bioquímicos e preenchimento de questionário aplicado ao tutor. Os principais achados foram aumento VCM (volume corpuscular médio) e proteínas totais, redução do número de hemácias, aumento das concentrações circulantes de colesterol total, triglicerídeos e ureia no grupo OB, enquanto o grupo SP mostrou aumento somente de colesterol total e ureia. Ademais, os grupos OB e SP apresentaram maior frequência de alimentação ad libitum, categorizada como premium e gatos com menor nível de atividade. Assim, conclui-se que o sobrepeso e a obesidade alteraram parâmetros hematológicos e bioquímicos. Além disso, fatores relacionados ao manejo alimentar e o ambiental dos gatos podem ser preditivos para um risco aumentado de excesso de peso.

Abstract in English:

This study evaluated palatine tonsils from 327 water buffaloes collected in a slaughterhouse located in the city of Belém, Pará State, Brazil, over four months (nine sample collecting visits). The overwhelming majority (84.71%) of these buffaloes came from Marajó Island, Pará State, Brazil. The main pathological findings were crypt dilatations/keratin cysts (96.0%, 314 cases), mild to moderate follicular lymphoid hyperplasia (93.0%, 304 cases), crypt abscesses (79.8%, 261 cases), tonsillar corpuscles (31.2%, 102 cases) and tuberculoid granulomas (1.53%, 5 cases). Acid-fast bacilli (AFB) were observed in 20% (1 out of 5 cases) of these granulomas. The study indicates that pathological evaluation of tonsils in buffaloes can provide details of structural features of the organ in the species and information on subclinical or asymptomatic tonsillitis.

Abstract in English:

This study aims to establish a therapy strategy for canine leukopenia induced by canine parvovirus (CPV) infection through intravenous infusion of allogeneic bone marrow mesenchymal stem cells (BMMSCs) and to evaluate the therapeutic effect of BMMSCs on canine parvovirus. Forty healthy 2-month-old dogs were randomly divided into four groups including the BMMSC treatment group (A), conventional treatment group (B), CPV infection group (C), and a normal control group (D). Then the A, B, and C groups were orally infected with CPV (103.25 TCID50/mL) at 1mL/kg, and the D group received the same dose of saline. After the onset of infection, Group A received mesenchymal stem cells (MSCs) and rehydration as the treatment; Group B was treated with anti-inflammatory therapeutics and rehydration; and Group C and D were injected with the same dose of physiological saline. The level of leukocytes rebounded significantly after the treatment with BMMSCs and returned to reference numbers on Day 3 after treatment, which was significantly higher than that in the conventional treatment group. The concentrations of IL-2 and IFN-α were gradually increased during the treatment, and the BMMSC treatment group exhibited significantly higher IL-2 and IFN-α concentrations than the conventional treatment group on Days 3 and 4. The expression of the virus in the blood gradually decreased during the treatment, and the BMMSC treatment group displayed a faster decrease than the conventional treatment group. These results showed the advantages of BMMSC treatment over conventional treatment. This study provides a new BMMSC treatment strategy for canine leukopenia induced by CPV infection and reveals the mechanism by which BMMSC increases leukocytes after CPV infection.

Este estudo tem como objetivo estabelecer uma estratégia terapêutica de leucopenia canina induzida pela infecção por parvovírus canino (CPV) através de infusão intravenosa de células tronco mesenquimais da medula óssea alogênica (BMMSCs) e avaliar o efeito terapêutico de BMMSCs no parvovírus canino. Quarenta cães saudáveis de dois meses de idade foram divididos aleatoriamente em quatro grupos: o grupo de tratamento de BMMSCs (A), o grupo de terapia convencional (B), o grupo de infecção por CPV (C) e um grupo controle (D). Os grupos A, B e C foram infectados oralmente com CPV (103.25 TCID50/mL) a 1mL/kg e o D recebeu a mesma dose de soro fisiológico. Após o início da infecção, o grupo A recebeu uma dose de derivadas da medula óssea (CTMMO) e hidratação como tratamento, o grupo B foi tratado com terapia anti-inflamatória e hidratação, e grupos C e D foram injetados com a mesma dose de soro fisiológico. As concentrações de IL-2 e IFN-α aumentaram gradualmente durante o tratamento, e o grupo de tratamento BMMSC mostrou concentrações significativamente maiores de IL-2 e IFN-α do que o grupo de tratamento convencional nos Dias 3 e 4. A expressão de vírus no sangue diminuiu gradualmente durante o tratamento, e o grupo de tratamento BMMSC mostrou uma diminuição mais rápida do que o grupo de tratamento convencional. Esses resultados mostraram as vantagens do tratamento BMMSC em relação ao tratamento convencional. Este estudo fornece uma nova estratégia de tratamento da BMMSC para leucopenia canina induzida pela infecção por VCP e revela o mecanismo pelo qual a BMMSC aumenta os leucócitos após infecção por VCP.

Abstract in English:

In Brazil, the Atlantic Forest has been suffering from deforestation, which has had impacts on its flora, fauna, and microbiota. However, the fungal diversity present in these environments is little known and studied. In this study, a total of 90 samples of 45 wild birds (45 feathers and 45 feces) were collected in Ilha da Marambaia, southeastern Brazil. Filamentous fungi isolated from these samples were identified through macroscopic and microscopic characteristics. Some isolates were identified by molecular biology using the PCR technique. Acremonium, Alternaria, Aspergillus, Cunninghamella, Curvularia, Eurotium, Fusarium, Geotrichum, Neosartorya, Pestalotia, Paecilomyces, Penicillium, Rhizopus, Mucor and Syncephalastrum were identified. These results indicate the presence of saprophytic fungi species in the feathers and feces of wild birds of the capture site. Further studies should be conducted to elucidate if the mycobiota profile modifies with anthropization and if it interferes with bird health and environmental recovery.
