“…However, other factors of non-infectious origin, such as lactation stage, animal age and season, among others, may also influence CMT results, which is considered an indirect indicator of milk SCC, but the effects are minimal in uninfected mammary glands (Reneau, 1986;Harmon, 1994). Buffaloes are considered less susceptible to mastitis than cows, because of specific anatomical and physiological characteristics; several studies have reported low occurrence of clinical and subclinical mastitis in this species, in spite of the similarity of the etiologic agents in the two species (Jorge et al, 2005;Kapronezai et al, 2005;Carvalho et al, 2007;Sollecito et al, 2011).…”

The aim of this study was to evaluate somatic cell count (SCC), prevalence and etiology of mastitis in a dairy buffalo herd from Analândia, São Paulo State, Brazil, in the dry and rainy seasons. Additionally, antimicrobial susceptibility profile of microorganisms isolated from milk samples was also evaluated. 1,042 milk samples from female Murrah buffaloes in a dairy farm located in Analândia, São Paulo State, Brazil, collected between May 2011 and November 2012 were analyzed. After the mammary gland physical examination, strip cup test and California Mastitis Test (CMT) were performed. Afterwards, 50mL of milk samples from each mammary quarter were collected aseptically for SCC in automatic equipment and microbiological examination. The antimicrobial sensitivity profile to ampicillin, cefoperazone, ceftiofur, enrofloxacin, gentamicin, neomycin, oxacillin, penicillin, and sulfamethoxazole/trimethoprim was evaluated by disk diffusion method. The monthly average temperature and pluviometric index were obtained from "Centro Integrado de Informações Agrometeorológicas" (CIIAGRO) of "Instituto Agronômico de Campinas" (IAC). Milk samples with positive results in the microbiological test showed average SCC of 137,720 cells/mL in the dry period and 190,309 cells/mL in the rainy period. Although a higher number of isolated microorganisms was observed in buffalo milk samples during the rainy period (69/600) compared to the dry period (50/442), the season had no significant effect on the frequency of isolation of microorganisms.

“…The disease interferes directly in the milk quality and countless efforts have been made for its control and prevention (Pedrini & Margatho 2003, Freitas et al 2005, Carvalho et al 2007. It is an illness of multi-etiologic and multifactorial origin that assaults the majority of the world's dairy herd and causes problem in the whole productive chain, even for the consumer, which may receive a final product of low quality (Costa 1999).…”

Risk factors associated with buffalo mastitis in the Brazilian Northeast

et al. 2011

Risk factors for subclinical mastitis were studied in 474 buffaloes cows proceeding from four dairy farms located in the states of Pernambuco, Alagoas, Bahia and Ceará, Brazil. Milk samples (n=1896) of lactating buffaloes cows were examined for somatic cells count (SCC) and microbiologic exam, and a questionnaire composed by objective questions was applied in order to obtain animals and herd management data. Risk factors analysis was performed in two stages: univariate and mutivariate analysis. Two analysis were performed, one considering the animal classification for SCC as the dependent variable (<400,000 -negative; >400,000 -positive) and another, considering the microbiologic exam result (positive and negative). In the multivariate analysis considering SCC as dependent variable, the lack of teat washing was the only variable identified as a risk factor, so that farms without this procedure before the milking presented risk of infection of 2.68 (I.C. 1.49-4.83). In the multivariate analysis considering the microbiologic exam as dependent variable, it was observed that properties that performed the cleaning of the milking equipment manually presented risk of 1.85 (I.CI. 1.32-3.64), which was higher than those properties that performed the cleaning mechanically (p=0.019). Risk factors for the occurrence of subclinical mastitis in dairy buffaloes in Brazilian Northeast farms were related to the characteristics of improper milking management. Risk factors identified in this study must be carefully corrected in order to reduce the frequency of mastitis cases, and therefore, contribute for disease control and prevention in the herds. RESUMO.-[Fatores de risco associados à mastite bubalina no Nordeste brasileiro.]Foram estudados os fatores de risco para mastite subclínica em 474 búfalas procedentes de quatro propriedades de exploração leiteira situadas nos Estados de Pernambuco, Alagoas, Bahia e Ceará. Amostras de leite (n=1896) de búfalas em lactação foram examinadas para contagem de células somáticas (CCS) e exame microbiológico, e um questionário constituído de perguntas objetivas foi aplicado para obtenção de dados dos animais e do manejo do rebanho. A análise dos fatores de risco foi efetuada em duas eta-pas: análise univariada e multivariada. Foram realizadas duas análises, uma considerando a classificação dos animais quanto à CCS como variável dependente (<400.000 -negativo; > 400.000 -positivo) e outra considerando o resultado do exame microbiológico (positivo e negativo).

“…No entanto, a ação bacteriana pode comprometer a composição do leite em razão do consumo de lactose e deterioração de proteínas e lipídeos pelas suas enzimas. Apesar de levar a perdas econômicas em toda cadeia produtiva, sobretudo no rendimento e qualidade de derivados lácteos (CARVALHO et al, 2007), o problema maior recai sobre o consumidor final, que fica exposto a bactérias patogênicas e suas toxinas, frequentemente relatadas em surtos de toxinfecções alimentares (BORGES et al, 2008).…”

O resfriamento do leite após a ordenha em todas as dimensões dos tanques de expansão deve preservar as características do leite. Portanto, o objetivo do trabalho foi verificar a temperatura do leite cru mensurada por termostato e termômetro em pontos superficiais e do fundo de 33 tanques de expansão no Vale do Rio Doce (MG). Os dados foram relacionados com a qualidade do leite e conhecimento dos produtores quanto à refrigeração do leite. A temperatura média mensurada pelo termostato do tanque de refrigeração foi inferior (p<0,05) às temperaturas médias mensuradas pelos termômetros, mas estas foram iguais (p>0,05) em pontos diferentes no interior do tanque. A contagem bacteriana do leite foi maior (p<0,05) em tanques com alta temperatura de armazenamento, o que causou desconformidade de 42,4% de amostras quanto a legislação. A falta de informação dos produtores a respeito da refrigeração correta do leite e a refrigeração inadequada de tanques comprometeram a qualidade e conformidade de 10% de amostras quanto à legislação. A manutenção e inspeção de tanques devem ser efetivadas de forma constante. PALAVRAS-CHAVE:Qualidade. Refrigeração. Legislação. Inspeção.
