| ABSTRACT: We compared the potential of routine techniques used for the identification of Staphylococcus species, aiming to evaluate their accuracy in the detection of 43 Staphylococcus chromogenes strains isolated from bovine mastitis that, despite being a coagulase-negative species, are able to clot plasma. These strains could be mistakenly suspected to be S. aureus and lead to an unappropriated treatment of the disease. MALDI-TOF, PCR-RFLP of the chaperonine gene groEL, and sequencing of the 16S rRNA and elongation factor Tu gene tuf were employed. Results from the four methods were coincident for only half of the strains because of the low accuracy of the groEL PCR-RFLP (51.2% accuracy). Even though all the sequencing results were identical, the high... |

| The purpose of this study was to evaluate the monthly milk production and quality of buffaloes from two milk production systems in the Brazilian northeast using the multivariate analysis: principal component analysis (PCA). A total of 2,506 individual milk recordings were performed in two production systems, containing information on milk production (kg day-1), fat, protein, lactose and total solids counts and somatic cell count (SCC). There were positive correlations between the fat content and the contents of total solids (TS) and protein, and of TS and protein. From the PCA, two main components (PC1 and PC2) were identified, explaining 67.71% of the total variation. The fat, protein, lactose and ST level, represented by PC1, explain 46.18% of the total... |

| ABSTRACT The present study aimed to compare two MALDI-TOF identification methods [(a) direct sample identification after pre-incubation; or (b) use of bacteria isolated on pre-culture)] to standard, traditional bench microbiology. A total of 120 quarter milk samples from 40 Holstein lactating cows were screened based on culture-positive results obtained by microbiological culture (reference method) with the following numbers of quarters positive per cow: 4 cows with 1, 8 cows with 2, 12 cows with 3 and 16 cows with 4 infected quarters per cow. For direct identification method, quarter milk samples (n = 120) were skimmed by centrifugation (10,000 × g/10 min) and pre-incubated at 37 ºC for 12 h. After pre-incubation, quarter milk samples were submitted to... |

| ABSTRACT Mammary disorders in mares are rare and usually only one animal per paddock is affected. In this report, two mares with 7 and 9 years old, were concomitantly diagnosis of chronic pyogranulomatous mastitis, associated with the Splendore-Hoeppli reaction, indicative of botryomycosis a rare, chronic suppurative disease with microabscess formation, characterized by in vivo formation of eosinophilic materials around microorganisms or biologically inert material. Various bacteria can cause botryomycosis in horses, and the most frequently isolated one is Staphylococcus sp., particularly S. aureus. This report confirms the role of Staphylococcus sp.; however, specifically S. hyicus and S. cohnii that prior to the current report, had not been associated... |

| Avaliou-se o risco de infecção em diferentes fases da lactação em 33 ovelhas da raça Santa Inês. Inicialmente a glândula foi submetida ao exame físico e à prova de fundo escuro. Posteriormente, amostras de leite foram coletadas assepticamente para a realização de exame bacteriológico - California Mastitis teste -, e contagens microscópica e automática de células somáticas. Nenhuma diferença foi observada entre as distintas fases de lactação. Observou-se alta persistência de infecções intramamárias, e tendência a maior contagem de células somáticas no último período de lactação, que pode ser oriunda da maior resistência a infecções neste período. |

| A non-lactating 17-year-old grey barren Mangalarga Marchador mare was referred to the Large Animal Veterinary Hospital of the Federal Rural University of Rio de Janeiro (UFRRJ), presenting enlargement of the mammary gland. The owner reported that the animal had a lesion in the mammary gland for at least two years, diagnosed and treated as chronic mastitis. Initially only the right gland was involved, presenting ulceration and exudation on the cutaneous surface. After 20 months, the left gland also became affected. The diagnosis of tubulo-papillary adenocarcinoma was based on the typical microscopic lesions. This work shows the importance of the histopathological examination in the differential diagnosis between the neoplasms and the chronic inflammation in... |

| This study aimed to detect methicillin resistant and slime producing Staphylococcus aureus in cases of bovine mastitis. A triplex PCR was optimized targetting 16S rRNA, nuc and mecA genes for detection of Staphylococcus species, S. aureus and methicillin resistance, respectively. Furthermore, for detection of slime producing strains, a PCR assay targetting icaA and icaD genes was performed. In this study, 59 strains were detected as S. aureus by both conventional tests and PCR, and 13 of them were found to be methicillin resistant and 4 (30.7%) were positive for mecA gene. Although 22 of 59 (37.2%) S. aureus isolates were slime-producing in Congo Red Agar, in PCR analysis only 15 were positive for both icaA and icaD genes. Sixteen and 38 out of 59 strains... |

| Mastitis is an inflammation of the mammary gland that causes severe economic losses due to reduced milk production, expence on pharmaceuticals, veterinary care, discarding of milk after treatment and discarding of affected animals. This inflammatory process may have distinct origins, but all cases of economic importance are caused by microorganisms. According to their origin and means of transmission, the main etiological agents were put together in two groups, contagious microorganisms (Streptococcus agalactiae, Staphylococcus sp, e Corynebacterium bovis) transmitted mainly during rnilking and environmental microorganisms (Streptococcus uberis, Enterobacteriaceae, fungos, algae of the genus Prototheca, etc.).Clinical mastitis is characterized by visible... |

| Mycoplasma bovis es el mycoplasma causante de mastitis más importante en vacas lecheras y ha sido diagnosticado en nuestro país así como a nivel mundial. Para realizar estudios epidemiológicos de brotes, el análisis por MLVA parece ser una herramienta adecuada para la tipificación genética del patógeno. En el presente trabajo se analizaron 7 cepas de M. bovis provenientes de 2 tambos distintos (muestras de leche de tanque de enfriado, y cuartos mamarios de vacas con y sin signos de mastitis) que habían sido previamente identificadas. Se estudiaron por PCR 4 regiones que comprenden secuencias repetidas en tándem (TR). Dentro de los loci TR analizados, sólo se encontró variabilidad en TR 52, en el cual se observaron 2 posibles alelos en muestras que... |
