background: the objective of the study was to evaluate the presence of neospora caninum organisms in the brain of aborted fetuses and placentas of full-term calves born of seropositive cows. methods: during 2006-2007, 12 brains of aborted calves from neospora seropositive cattle and 7 pla­centas from seropositive dams giving birth to full-term calves, from four dairy cattle farms located around...

Neospora is a cyst-forming coccidian parasite that causes abortions and neuromuscular disorders in a wide variety of mammals. Japanese bovine isolate JPA1 was inoculated intraperitoneally into BALB/c nu/ nu (athymic nude) and BALB/c (congenic wild type) female mice to examine the distribution of parasites and resistance mechanisms to Neospora infection. All the athymic nude mice died within 28 ...

background : neospora caninum is considered one of the major causes of repeated abortions in livestock. this study aimed to determine the seropositivity to n. cani-num using indirect elisa and the influence of the infection on the occurrence of abortions in selected dairy herd in slovakia. method: blood samples were obtained from 490 cattle over a period of two years and were tested for n. cani...

Neospora caninum, a protozoan parasite closely related to Toxoplasma gondii, causes abortion and congenital infection in cattle. To investigate specific methods of antemortem diagnosis, the antibody responses of infected cows were evaluated by immunoblot assay and competitive inhibition enzyme-linked immunosorbent assay (CI-ELISA) by using a monoclonal antibody (MAb), MAb 4A4-2, against N. cani...

Neospora caninum and Toxoplasma gondii are closely related intracellular protozoan parasites associated with bovine and ovine abortion respectively. Little is known about the extent of Neospora/Toxoplasma co-infection in naturally infected populations of animals. Using nested PCR techniques, based on primers from the Nc5 region of N. caninum and SAG1 for T. gondii, the prevalence of N. caninum ...

Abstract Between December 2016 and April 2017, a spate of abortions occurred in closed dairy herd from the central eastern region Paraná, Brazil, which 75 cows aborted. To identify its cause, organ fragments were collected an aborted fetus for histopathology, blood samples stillborn, 4 fetuses, 9 farm dogs indirect fluorescent antibody technique (IFAT). These tests found multifocal non-suppurat...

In this study, two halophilic bacterial strains isolated from saline habitats in Argentina grew in the presence of gas oil. They were identified as Halomonas spp. and Nesterenkonia sp. by 16S ribosomal RNA sequencing. Chemotaxis towards gas oil was observed in Halomonas spp. by using swimming assays.

background: neospora caninum is an apicomplexan protozoa,which causes abortion in cattle worldwide. objectives:the present study was designed to estimate the rate oftransplacental transmission of n.caninum to aborted fetuses inseropositive dams in dairy farms in mashhad area, iran.methods: two hundred blood samples of dam with abortedbovine fetuses were collected from dairy farms from 2008 to20...
