Compliance of biosecurity practices for compartmentalization to foot-mouth disease and classical swine fever viruses in commercial swine companies from southern Brazil.

Classical swine fever (CSF) and foot-mouth disease (FMD) are both highly contagious disease and disruptive to commercial trades, but they are examples of foreign animal diseases that biosecurity-based compartmentalization could be used to support trade in free zones in response to an outbreak. This study aimed to evaluate biosecurity compliance to the Federal Normative Instruction #44 from December 4th, 2017 (BRAZIL, 2017) in commercial swine farms located in southern Brazil. A total of 604 swine farms from 10 commercial swine companies were sampled, from which 28.

Description of bovine babesiosis and anaplasmosis outbreaks in northern Uruguay between 2016 and 2018.

Bovine babesiosis and anaplasmosis cause important economic losses in livestock production. In Uruguay, the main aetiological agents of bovine babesiosis and anaplasmosis are Babesia bovis, B. bigemina and Anaplasma marginale.

Serological Evidence of Human Infection with after Occupational Exposure to Aborting Cattle.

Cattle are broadly deemed a source of ; however, evidence reinforcing their role in human infection is scarce. Most published human Q fever outbreaks relate to exposure to small ruminants, notably goats. Anti-phase II IgG and IgM were measured by indirect fluorescent antibody tests in 27 farm and veterinary diagnostic laboratory workers to ascertain whether occupational exposure to cattle aborting due to was the probable source of exposure.

Serologic evidence of West Nile virus and Saint Louis encephalitis virus in horses from Southern Brazil.

Flaviviruses as West Nile virus (WNV), Saint Louis encephalitis virus (SLEV), Ilhéus virus (ILHV), and Rocio virus (ROCV) are previously reported in different Brazilian regions, but studies in Southern Brazil are still scarce. To improve the information regarding flaviviruses in Southern Brazil, horse serum samples were analyzed using RT-qPCR and a commercial ELISA-Ab against WNV followed by PRNT. All 1000 samples analyzed by real-time RT-PCR resulted negative.
