La aplicación bilateral intraepididimal en el perro de clorhexidina gluconato al 3% produce Azoospermia en el eyaculado a los 14 días post-aplicación. Mientras que la clorhexidina gluconato al 1,5% en asociación con cetrimida al 15%, la azoospermia se presenta a la primera semana post-aplicación. Considerándose, una alternativa para el control permanente de la capacidad reproductiva del macho y por ser económica, de fácil aplicación y sin mayores complicaciones de post aplicación se recomienda para los programas de control masivo de la natalidad.

The study aimed to determine the prevalence of zoonotic liver helminths and their histopathological characterization in rodents (Rattus spp.) from a zoo, pig farms and food markets in Lima, Perú. The morphometric parameters of each rodent were recorded to determine the age and identify the species, computing a total of 267 animals. The handling and the capture methodology were carried out according to the biosafety standards established by the Center for Infectious Diseases and Prevention of Atlanta. Livers were macroscopically evaluated for lesions. For diagnostic confirmation by histopathology, samples were taken from the right lateral lobe of all the livers together with other areas that showed damage in search of tissue lesions and inflammatory response related to the presence of the parasites. The pathological analysis determined a prevalence of 3.74% of Cysticercus fasciolaris in ...

The clinical effects, sperm parameters and macroscopic and histological lesions caused by chemical castration in dogs through the application of sclerosing substances were evaluated. Three groups were established: (G1, n=10), 4% chlorhexidine gluconate, (G2, n=10), 4% benzalkonium chloride + 0.4% cetrimide, and (G3, control, n=5) chloride of 0.9% sodium, at a dose of 0.5-1.0 ml intra-epididymal (IEPD) and bilateral on day 0. The effects were evaluated on days 2, 7, 14, 28 and 56 post-application. The manifest oligospermia was observed in 9/10 animals of G1 (90%) and in 7/10 of G2 at day 2 post-application, with a critical decrease of sperm concentration (3.78 ± 6.3 x 106/ml and 0.95 ± 0.89 x 106/ml, respectively, motility of 0.10 ± 0.32 - 0.20 ± 0.42% with oscillatory movement, without progressive advance and vitality of 0.30 ± 0.67% - 0% in both groups. Azoospermia was detected in ...
