| SUMMARY Ovine mastitis causes varying economic fosses in all countries where sheep are kept. A survey of 3128 breeding ewes in 22 farms in two areas with different management practices in Southern Brazil showed that the average prevalence of subclinical and chronic mastitis was 14.1% of ewes with at least one affected gland. From those, 4.49% were also bacteriologically positive. The prevalence in individual farms varied from 0 to 37% of ewes with clinical abnormalities of the udder. The overall prevalence was greater in Area II, where meat breeds predominate and animals are housed at night. It is concluded that subclinical and chronic mastitis is uniikely to be an economic problem in Area I, where wool production is the objective of the sheep industry.... |

| A mastite e uma doenca altamente prevalente em rebalnhos leiteiros de todo o mundo. Os agentes causais das mastites em caprinos sao semelhantes aqueles da doenca em bovinos, sendo os Staphylococcus coagulase positiva os mais frequentes patogenos associados a forma clinica e os Staphylococcus coagulase negativa a forma subclinica da mastite caprina. O diagnostico da mastite clinica e facil, baseado primariamente nos sinais clinicos; entretanto, o diagnostico da forma subclinica e um problema, tendo-se como metodos auxiliares os testes fisico-quimicos do leite e os baseados no aumento do conteudo celular da glandula mamaria. Por serem rapidos e de facil execucao, os testes baseados no aumento celular do leite sao muito utilizados, sendo o California Mastitis... |

| The NAHMS Dairy '96 Study was designed to provide both participants and the industry with information on the nation's dairy animal population for education and research. The USDA's National Agricultural Statistics Service (NASS) collaborated with NAHMS to select a statistically valid sample yielding 2,542 producers. Included in the study were 20 states that represented 83.1 percent of the U.S. milk cows as of January 1, 1996. Veterinary Medical Officers (VMO's) and Animal Health Technicians (AHT's) collected data for Part III from 1,219 operations that had 30 or more milk cows on January 1, 1996, from February 20 through May 24, 1996.

| 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... |

| El objetivo del presente trabajo fue probar una nueva expresión matemática destinada a mejorar la interpretación de los recuentos de células somáticas y niveles de producción de leche. Un modelo múltiple de curva de lactancia se comparó con el modelo clásico de Wood, separadamente para cada uno de los rangos celulares (RC). Se trabajó con una base de datos depurada proveniente del control sistemático de cinco rebaños lecheros que representan una masa de 1200 vacas Holstein Friesian. Se ajustó una curva de producción de leche, separadamente para vaquillas y vacas, mediante la expresión y(t) = a t b e- c t. El modelo múltiple propuesto estuvo basado en la ecuación anterior, incorporando la variable RC en la forma y (t, RC = a t b e- c t e d RC + f RC2. El... |

| A concentração inibitória mínima-MIC em 30 estirpes de Pseudomonas aeruginosa isoladas de mastite bovina foi avaliada utilizando o E-test padrão e o método modificado, pela adição de Tris-EDTA e DMSO. Os métodos modificados apresentaram redução significativa da MIC das estirpes utilizando a gentamicina, a ciprofloxacina e a norfloxacina. |

| 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... |

| With the objective to know the mastitis cost for milk producer, was developed this study, with duration of a year in a milk farm of the North region of Sonora. The cost of the clinical and subclinical mastitis was estimated, taking into account the milk production, treatment costs and commercial milk value. The information was recorded monthly, the incidence of subclinical mastitis was obtained using California MastitisTest (CMT) and clinical mastitis incidence was obtained from farm health records. Was an incidence average of 18,3% of subclinical mastitis, whereas the incidence of the clinical form of mastitis was of 5,35%. The average monthly cost of each animal with mastitis was $185.40; altogether the mastitis had a cost of $30.966,34 annually,... |

| 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... |
