The development of Sarcocystis falcatula merozoites in bovine turbinate (BT) cell cultures is described and compared with development of Sarcocystis neurona merozoites. Merozoites of S. falcatula entered BT cell cultures and increased in size until 3 days post-inoculation when the nucleus of some merozoites developed lobes. Developing schizonts present at 4 days contained a lobed nucleus or app...

Este estudo avaliou a composição e os requisitos mínimos de identidade qualidade da carne bovina previamente moída exposta à venda em estabelecimentos varejistas no Estado do Rio Janeiro. As amostras foram coletadas nos período entre março abril 2019. Os produtos analisados quanto composição, apresentação, temperatura, o pH, teor lipídios, morfologia histoquímica, identificação espécie animal q...

Understanding how closely related wildlife species and their domesticated counterparts exchange or share parasites, or replace each other in parasite life cycles, is of great interest to veterinary and human public health, and wildlife ecology. Grey wolves (Canis lupus) host and spread endoparasites that can either directly infect canid conspecifics or their prey serving as intermediate hosts o...

INTRODUCTION Sarcocystosis is mainly a veterinary problem; however, humans can serve as the definitive host for at least two species (Sarcocystis hominis and Sarcocystis suihominis). Intestinal infections occur in the definitive host after ingesting the intramuscular cysts (sarcocysts) in the intermediate host, which initiate sexual stages in the intestine that terminate in oocysts excreted in ...

The development and merozoite production of Sarcocystis falcatula and 2 isolates (SN6 and SN2) of Sarcocystis neurona were studied in various cultured cell lines inoculated with culture-derived merozoites. All 3 parasites underwent multiple cycles of schizogony in VERO cells, bovine monocytes (M617 cells), and bovine pulmonary artery endothelial cells (CPA). Sarcocystis neurona strains SN6 and ...

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.
