Contribuição ao conhecimento da incidência da brucelose no Estado do Paraná (Brasil)

Abstract

O rebanho bovino paranaense apresenta um índice de brucelose relativamente alto, particularmente no Norte e Leste do Estado. O gado leiteiro revelou um índice de 7,90%, com um foco grave no Município de Castro (29,92%). Bovinos criados em regime extensivo de pastagens naturais se apresentam com menor grau de infecção, pois a maior incidência foi encontrada no Norte do Estado, onde, regra geral, os campos são constituídos de pastos artificiais.<br>The author carried out an examination of brucellosis on the cattle of the State of Paraná (Brazil). In cow milk, an incidence of 7,90 percent was found, but a severe focus was located in Castro county (29,92 percent). In cattle, breaded extensively, the incidence was 16,49 percent. An higher percentage was located particular in the vicinity of the State of São Paulo, in which the livestock in general are kept on artificial pasturages. Sixty breeding farms were visited and 1716 samples of serum,sera from cattle were examined, as well as 797 sera from cow’s milk

Occurrence of brucellosis, leptospirosis and neosporosis in cows with retained placenta in Southwest Paraná, Brazil

“…Although no animal showed brucellosis, this disease affects approximately 5% of cattle (Brasil 2006) and is also related to retained placenta. Palmquist (2001) reported 7.9% prevalence of brucellosis in dairy cattle from the north and east of Paraná. In other Brazilian studies, prevalence was found as 4% (Dias et al 2009), 0.14% (Sabedot et al 2009), 0.32% Fig.1.…”

Fatores de risco e soroprevalência da Brucelose em assentamento rural no Município de Aragominas - TO, Brasil

“…Em rebanhos leiteiros, as frequências de infecção pela detecção de anticorpos contra B. abortus, no Brasil, podem variar de 1,22%, conforme Poletto et al (2004) realizando estudo em Passo Fundo -Rio Grande do Sul; a 16,49%, conforme trabalho de Palmquist (2001) no estado do Paraná.…”
