Avipoxvirus (APV) is a fairly common virus affecting birds that causes morbidity and mortality in wild and captive birds. We studied the prevalence of pox-like lesions and genetic diversity of APV in house sparrows (Passer domesticus) in natural, agricultural and urban areas in southern Spain in 2013 and 2014 and in central Spain for 8 months (2012-2013). Overall, 3.2% of 2,341 house sparrows v...
Cobalt-60 Irradiation/Testis/House Sparrow (Passer domesticus, Linn.) Adult male house sparrows were exposed to Co-60 external irradiation at doses of 475, 712 and 950R. The dose rate was 100 R/hr at a distance of one foot. The birds were autopsied at intervals of 1, 3, 5, 7 and 15 days after irradiation. Testes were studied for histopathological damage produced.
