Occurrence of gastrointestinal protozoans in cats from Londrina, Paraná, Brazil

Protozoans are widely distributed, and several species may parasitize the digestive tracts of cats (Felis catus), and can be transmitted to humans. The present study aimed to evaluate the species and occurrence of gastrointestinal protozoans in cats in the city of Londrina, Paraná, Brazil. A total of 206 cat fecal samples were tested, of which 141 were from shelter animals, and 65 were from pets owned by local ...

First molecular detection of Eimeria spp. in eared doves (Zenaida auriculata) f...

The aim of the present study was to detect Eimeria spp. in eared doves (Zenaida auriculata) from Brazil. Two hundred and fourteen birds were trap-capture in different regions of Londrina city, Paraná state, Southern Brazil. Fecal samples were collected, and DNA extraction was performed. A nested PCR based on the subunit I of the cytochrome c oxidase gene of the Eimeria mitochondrial genome was used to detect th...

Molecular detection of Babesia vogeli, Ehrlichia canis and Anaplasma platys in ...

There is an increase in tick-borne diseases in dogs in urban and rural areas in Brazil and some of these are of public health importance. Rhipicephalus sanguineus-transmitted hemoparasitoses are the main causes of mortality in dogs. The present study investigated the molecular occurrence of Ehrlichia canis, Babesia vogeli and Anaplasma platys in dogs with clinical sings and hematological abnormalities suggestiv...

Development of a qPCR to diagnose the genus Eimeria in bovines

Bovine coccidiosis is caused by protozoa of the genus Eimeria. These protozoa mainly affect young animals, causing a decrease in production and consequent economic losses. The routine diagnosis is made through morphological observation of the oocysts, which has several limitations. The objective of the present study was to develop a qPCR technique for the diagnose of Eimeria spp. in cattle. For this purpose, th...

Neospora caninum: seroepidemiology of cows and dogs from milk farms of Cunha, S...

Neosporosis, a parasitic disease prevalent worldwide, is caused by the protozoan Neospora caninum, an obligatory intracellular parasite that can cause abortions and infertility in females, resulting in high economic losses. The aim of this study was to determine the seroprevalence of antibodies against N. caninum in dairy cattle, and the occurrence of antibodies in dogs from farms in the municipality of Cunha, ...

Congenital toxoplasmosis in chronically infected and subsequently challenged ewes

Made available in DSpace on 2018-12-11T17:07:21Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-10-01; This experiment studied congenital transmission in sheep experimentally infected with oocysts of Toxoplasma gondii and reinfected at one of three stages of pregnancy. Twenty ewes were experimentally infected with T. gondii strain ME49 (day 0). After the T. gondii infection became chronic (IFAT≤512), the...
