Abortion and congenital transmission of Trypanosoma vivax in goats and ewes in semiarid northeastern Brazil.

The main effects of trypanosomosis in Brazil are related to reproductive alterations. In this context, the present study aimed to report the occurrence of abortions in goats and sheeps in the semiarid region of Northeastern Brazil, associated with Trypanosoma vivax. Trypomastigotes forms visualized by Buffy coat technique (BCT) method in 68.

Cardiac involvement in trypanosomiasis in sheep experimentally infected by Trypanosoma vivax (Ziemman, 1905).

The objective of the present study was to evaluate the clinical signs, electrocardiographic signs and evolution of histopathological lesions in the heart of sheep experimentally infected by Trypanosoma vivax during the acute and chronic phases of infection as well as to investigate the presence of parasitic DNA in the heart using polymerase chain reaction (PCR). Twenty-two male sheep were divided into the following four groups: G1, which consisted of six sheep infected by T. vivax that were evaluated until 20 days post-infection (dpi; acute phase); G2, which consisted of six sheep infected by T.

Detection of Trypanosoma vivax DNA in semen from experimentally infected goats.

The present work aimed to investigate the presence of T. vivax DNA in the semen of experimentally infected goats. Twelve male goats native to the Brazilian Northeast, adults, were randomly assigned to two experimental groups: the infected group consisting of six goats infected intravenously with 0.

Lactation curve and milk quality of goats experimentally infected with Trypanosoma vivax.

The present study aimed to evaluate the effects of Trypanosoma vivax infection on the shape of the lactation curve and the milk quality of dairy goats experimentally infected with T. vivax. In total, twenty Saanen goats, aged 26-30 months and the same number of calving (two calvings), were divided into two experimental groups: an infected group, consisting of ten goats intravenously infected with 0.

Toxicity effects of toad (Rhinella jimi Stevaux, 2002) venom in chicken (Gallus gallus domesticus).

This study aimed to evaluate the pathological changes that occur after administering different doses of R. jimi (Stevaux, 2002) parotoid glands secretion to Gallus gallus domesticus chicks. Twenty-three animals were used in this study and were divided into 5 groups that received a toad venom dose of 0, 3.

Clinical and pathological effects of Calotropis procera exposure in sheep and rats.

This study aimed to describe the toxic effects resulting from the administration of Calotropis procera (Aiton) W. T. Aiton latex to rats and C.
