Comparison of five parasitological techniques for laboratory diagnosis of Balantidium coli cysts

Abstract Balantidium coli is a protozoon that can cause dysentery in humans, pigs and nonhuman primates, with zoonotic potential. In the literature, there is still little information on the effectiveness of different laboratory techniques for diagnosing this disease. This study compared and evaluated the...

Helminths of Molothrus bonariensis (Gmelin, 1789) (Passeriformes: Icteridae) from southernmost Brazil

Abstract Information about helminths of Molothrus bonariensis (Gmelin, 1789) (Passeriformes: Icteridae) are scarce; in this sense the objective of this paper was to contribute to its knowledge. Five hosts of southern Brazil were examined and the helminths Prosthogonimus ovatus, Tanaisia valida (Digenea),...

Efficacy of treatments with toltrazuril 7. 5% and lasalocid sodium in sheep naturally infected with Eimeria spp

Abstract The objective of this study was to evaluate the efficacy of an experimental formulation of toltrazuril 7.5% + Trimix™ on a naturally acquired infection of Eimeria spp. in suckling lambs kept on pasture and, in another trial, evaluate the comparative efficacy between lasalocid and toltrazur...

Molecular and morphological evidence of Taenia omissa in pumas (Puma concolor) in the Peruvian Highlands

Abstract A total of 41 cestodes were collected during necropsy examination on 2 pumas (Puma concolor) that were found in 2 communities in Canchis province, Cuzco region, Peru, at 4500 meters above sea level (Peruvian Andes).

Influence of the vegetation management of the leeves in irrigated rice organic in diversity of Hymenoptera parasitoids

Braz. j. biol; 76 (3), 2016
Abstract Among the natural enemies of insect pests in rice fields, parasitoids are especially notable. To better understand the space-time dynamics of these insects, the objectives of this study were to describe and compare groups of parasitoids in organic irrigated rice fields using two management appro...

Fabaceae and Myrtaceae were the plant families with the greatest richness of insect galls (4 and 6 morphotype...

Detección molecular de Sarcocystis aucheniae en sangre de llamas de Argentina
Molecular detection of Sarcocystis aucheniae in the blood of llamas from Argentina

Rev. argent. microbiol; 48 (3), 2016
Sarcocystis aucheniae are apicomplexan protozoa that infect South American camelids (SACs), giving rise to macroscopic cysts similar to rice grains in skeletal muscles. Visual detection of macrocysts in slaughtered animals hampers commercialization of SAC meat, a highly relevant economic exploitation for...
