Epidemiologia e sinais clínicos da conidiobolomicose em ovinos no Estado do Piauí

Epidemiological, clinical and diagnostic aspects of sheep conidiobolomycosis in Brazil

“…Table 2 lists the ovine conidiobolomycosis outbreaks reported in Brazil, including the years 1979 to 2014. Epidemiological conditions that determined the occurrence of the disease in sheep in the country were generally associated with periods of high rates of rainfall, temperatures between 19ºC and 36°C, high relative humidity and increased decaying plant matter on the environment (SILVA et al, 2007a;BOABAID et al, 2008;PEDROSO et al, 2009;FURLAN et al, 2010;MENDONÇA et al, 2012). Such conditions favor the proliferation of the fungus and, consequently, increase environmental contamination and predispose susceptible animals to inhalation of conidia.…”

“…Another route of contamination might be due to injury caused by sharp plants contaminated with conidia (KETTERER et al, 1992). SILVA et al (2007a) suggested that the prevalence of the disease in sheep might be related to the grazing habits of these animals favoring the inhalation of conidia.…”

“…For a long time, conidiobolomycosis in ovine was erroneously diagnosed as enzootic ethmoid tumor (SILVA et al, 2007a). However, the enzootic nasal tumor also known as enzootic nasal adenocarcinoma is a contagious chronic disease of goats and sheep, with viral etiology (retrovirus).…”

“…infection (SILVA et al, 2007a). So far, no drug or chemical has been completely effective in the treatment of conidiobolomycosis (RIET-CORREA et al, 2008;KIMURA et al, 2011;SILVA et al, 2012).…”

Aspectos epidemiológicos da conidiobolomicose em ovinos na região semiárida do Nordeste do Brasil

“…têm sido descritos no Piauí (SILVA et al, 2007a), Paraíba (RIET-CORREA et al, 2008), Mato Grosso (BOABAID et al, 2008;SILVEIRA et al, 2013), Rio Grande do Sul (PEDROSO et al, 2009) e Santa Catarina (FURLAN et al, 2010). Já focos de rinite rinofacial causados por P. insidiosum foram relatados no Mato Grosso (SANTURIO et al, 2008;UBIALI et al, 2013) e Paraíba (RIET-CORREA et al, 2008;PORTELA et al, 2010).…”
