A serological survey was carried out to assess the frequency of leptospirosis, small ruminants lentivirus (SRLV), and brucellosis in small ruminant herds in the Recôncavo Baiano, State of Bahia, Brazil, from February to December 2017. In four goat herds, 125 animals were tested for SRLV and leptospirosis, while in five sheep herds, 378 animals were tested for leptospirosis, brucellosis, and SRLV. Regarding leptospirosis, MAT detected 80% of goats and 15.34% of sheep seroreactive. Reactivity was most frequent to serogroups Autumnalis and Grippotyphosa in goats and sheep, respectively. Regarding SRLV, 8.8% of goats and 0.79% of sheep were reactive. Search for anti-B. ovis antibodies revealed 0.52% reactivity. In sheep, three animals showed simultaneous seroreactivity for SRLV and leptospirosis, while one animal had a serological response for brucellosis and leptospirosis. In goats, simultaneous seroreactivity for SRLV and leptospirosis was observed in only one animal. Leptospirosis was the most frequent of the three infectious diseases in investigated herds.

Ureteral ectopy is a rare disorder in the small animals’ clinic. It is characterized as a congenital anomaly, resulting from the ducts differentiation failure during embryogenesis. In this scenario, the ureters present themselves outside the anatomical site, being inserted into the uterus, urethra, urinary vesicle neck, or vagina. The clinical signs are urinary incontinence and perivulvar dermatitis. Surgery is the accepted treatment to correct the anomaly. The surgical procedure is based on relocating the ectopic ureter and treating associated modifications. This report describes a case of intramural bilateral ureteral ectopy, corrected surgically through the neoureterocystostomy technique, making it possible to control the animal’s urinary incontinence.

This case report presents the importance of articulation between legal professionals with the expertise of those who work in different areas of animal science and the activists of animal cause. The report is based on the experience that took place in the interior of the State of Bahia, with a donkey herd, the target of foreign groups interested in donkey hide exploration. The animals were rescued from mistreatment and slaughter, thanks to efficient legal work, aided by several areas of the veterinary sciences, and supported politically by the movement of animal activists. The union between activism and technical knowledge in the areas of health, breeding, nutrition, animal welfare, and legal knowledge is a tool that should not be overlooked. On the contrary, it has proved effective, confirming a strong and innovative link capable of saving animals, promoting their welfare, generating technical knowledge, and new and promising proposals for intersectoral action.

Pattern minas cheese is a product developed with pasteurized milk, fermented with mesophilic cultures, and with the final addition of rennet. This cheese undergoes an artisanal maturation process and possesses a firm shell of yellowish color and striking and acidic flavor. Our study objective was to evaluate the microbiological quality of pattern minas cheese. We collected 40 samples from two micro regions (Uberlândia and Patos de Minas) of the Triângulo Mineiro and Alto Paranaíba mesor regions of the State of Minas Gerais, Brazil. The microbiological test results were recorded as counts of enterobacteria, Escherichia coli, coliforms at 35°C, coagulase-positive Staphylococcus and Salmonella spp. In the Patos de Minas micro region, the results were 45%, 35%, 20%, and 20% higher than 103 CFU/g for the counts of enterobacteria, Escherichia coli, coliforms at 35°C, and Staphylococcus coagulase-positive, respectively. Five percent of the analyzed samples were positive for Salmonella spp. in the Uberlândia micro region. Based on the findings of the microbiota in the cheese analyzed from the micro regions (Uberlândia and Patos de Minas), we concluded that the hygiene conditions in the manufacturing, handling, transport, and storage stages were precarious, requiring the implementation of Good Manufacturing Practices (GMP) systems, including Hazard Analysis and Critical Control Points (HACCP).

Vitamin C supplementation is important for the growth and development of bullfrog tadpoles under optimum water temperature conditions. Therefore, an experiment was carried out to evaluate the effects of vitamin C supplementation on the diet of bullfrog tadpoles at a low temperature. A total of 480 tadpoles with a mean weight of 0.078 g were distributed in 12 aquariums each containing 40 L of water in a closed water recirculation system. The experimental design was entirely randomized with four treatments (0, 150, 300, and 600 mg kg-1 of L-ascorbic acid monophosphate) and three replicates. The productive performance was measured by the weight gain, feed conversion, diet consumption, protein efficiency, carcass yield, hepatosomatic index, viscerosomatic index, visceral fat index, dry matter, and ethereal carcass extract. The water temperature during the experimental period was 21.74 ± 0.43 °C. Vitamin C supplementation did not influence carcass yield and viscerosomatic index. However, there was a quadratic effect of vitamin C supplementation on the weight gain, apparent feed conversion, protein efficiency, visceral fat index, hepatosomatic index, and ethereal carcass extract. Based on these results, bullfrog tadpoles should be supplemented with 600 mg vitamin C kg-1 of the diet when subjected to water temperatures of around 22 °C.

Em rebanhos leiteiros, a suplementação com ácidos graxos poliinsaturados (PUFAs) é considerada uma ferramenta importante para diminuir o balanço energético negativo de vacas leiteiras durante o periparto e contribuir para a reprodução e sistema imunológico. Os efeitos da suplementação com PUFA sobre estes sistemas têm sido pouco explorados na literatura. Os PUFAs mais comuns na dieta dos ruminantes são Ômega-3 (n-3 PUFA) como ácido linolênico e Ômega-6 (n-6 PUFA) como ácido linoleico. Esta revisão abordará os aspectos gerais do n-3 PUFA, seus efeitos mais relevantes no sistema imune, principalmente seus efeitos nas células imunes, bem como seus efeitos na parte reprodutiva, tanto in vivo como in vitro, enfatizando a ação do n-3 PUFA através de mecanismos moleculares. A incorporação de n-3 PUFAs na dieta de vacas leiteiras exerce efeitos positivos na fertilidade e imunidade. Mais estudos a fim de explorar a função do n-3 PUFA na modulação do sistema imune e parâmetros reprodutivos, desde a investigação da biologia básica até a aplicação a campo de modo clínico e preventivo, devem ser requeridos.

Fifty-two Staphylococcus aureus recovered from papillary ostium and milk samples collected from cows with subclinical mastitis and milking environments in three small dairy herds located in southeastern Brazil were subjected to PCR identification based on the thermonuclease (nuc) gene. All the strains were submitted to in vitro antimicrobial susceptibility testing, and we investigated the sequence types (STs), agr groups (I-IV), virulence genes encoding for Microbial Surface Components Recognizing Adhesive Matrix Molecules (MSCRAMMs), biofilm-associated proteins, bi-component toxins, pyrogenic toxin superantigens, and enterotoxins. Screening for oxacillin resistance (2-6 μg/ml oxacillin), beta-lactamase activity assays, and PCR for the mecA/mecC genes detected 26 methicillin-susceptible S. aureus (MSSA) and 26 mec-independent oxacillin-nonsusceptible S. aureus (MIONSA). While MSSA isolates were found to be susceptible to all antimicrobial agents tested, or only resistant to penicillin and ampicillin, MIONSA isolates were multidrug-resistant. ST126-agr group II MSSA isolates were prevalent in milk (n=14) and carried a broad set of virulence genes (clfA, clfB, eno, fnbA, fiB, icaA, icaD, lukED, hla, and hlb), as well as the ST126-agr group II MIONSA isolated from milking liners (n=1), which also carried the eta gene. ST1-agr group III MIONSA isolates (n=4) were found in papillary ostium and milk, but most MIONSA isolates (n=21), which were identified in both papillary ostium and milking liners, were agr-negative and assigned to ST126. The agr-negative and agr group III lineages showed a low potential for virulence. Studies on the characterization of bovine-associated MSSA/MIONSA are essential to reduce S. aureus mastitis to prevent economic losses in dairy production and also to monitor the zoonotic potential of these pathogens associated with invasive infections and treatment failures in healthcare.

Dirofilariasis is a zoonotic disease caused by Dirofilaria immitis, a nematode found mainly in the pulmonary artery and right chambers of the heart, lungs, and large vessels of dogs. This parasitism also occasionally occurs in cats, causing an amicrofilaremic and asymptomatic infection, resulting in severe illness and rapid death. In this case report, it was described acute clinical signs and histopathological alterations in a domestic cat with heartworm disease from the city of Mossoró, the Rio Grande do Norte, Brazil. The nematode species, D. immitis, was confirmed by morphological and molecular analyses. This is the first documented and full report of feline heartworm disease in northeastern Brazil.

Donkeys (Equus asinus) face a global crisis. Their health, welfare, and even their local survival are compromised as the demand for their skins increases. Such demand for donkey skins aims to supply the ejiao industry. Ejiao is a traditional remedy made from the collagen of donkey skins. Some people believe it has medicinal properties. It is estimated that the ejiao industry currently requires approximately 4.8 million donkey skins per year. Although the future of the donkeys is still uncertain, we must guarantee a life free from suffering to the animals under our responsibility. The trade of donkey skins also undermines the cultural role of donkeys. Donkeys have developed an essential role in Brazil, especially in the Northeast region of the country, carrying on their backs construction materials, water, and food, and, as a consequence, helping people build cities in the deepest hinterland. The close relationship between people and donkeys affords donkeys a unique place in the local culture. This central importance has been recognized by Brazilian artists throughout history. We have many examples of songs, books, “cordeis” (typical Brazilian literature), poems, documentaries, movies, woodcuts, paintings, and sculptures, created to honor this important actor. Here we describe some examples of this human-donkey relationship, and its influence on our culture.

Boerka goat is the best meat type goat. Feed quality is one of the biggest factors that affect productivity, so it is necessary to know in advance the need for nutrients. The purpose of this study was to determine the dietray of crude protein (CP) and Total Digestible Nutrients (TDN) in efficient feed for the production of Boerka goats male growing phase. This study was designed in a completely randomized design, consisting of six combination feed treatments with six replications. Namely: 1 (CP 13.00% and TDN 63.10%); 2 (CP 13.03% and TDN 65.07%); 3 (CP 13.00% and TDN 70.00%); 4 (CP 15.00% and TDN 62.69%); 5 (CP 15.12% and TDN 65.00%); 6 (CP 15.00% and TDN 70.00%). The observed variables were feed consumption, feed consumption ratio (FCR), nutrient digestibility (dry matter, organic matter, crude protein) and average daily gain (ADG). Results of this study show that the balanced of CP and TDN has no significant effect on consumption and FCR. However, it was significantly different for digestibility and ADG. Feed treatment (CP 13.03% and TDN 65.07%) obtained the higher digestibility of DM and OM (71.49 and 70.5%), while the highest CP digestibility was treated with CP 15.05% and TDN 62.69% (71.59%). The ADG response of Boerka goats with CP 13.03% and TDN 65.07% was the good results (144.90 g head-1day-1) while the lowest response was on CP 13.08% and TDN 63.10%. It is concluded that the dietray of CP 13.03% and TDN 65.07% is a recommended of Boerka goat male growing phase.
