Eight hundred and thirteen European rodents and shrews encompassing seven different species were screened for alphacoronaviruses using PCR detection. Novel alphacoronaviruses were detected in the species Rattus norvegicus, Microtus agrestis, Sorex araneus and Myodes glareolus. These, together with the recently described Lucheng virus found in China, form a distinct rodent/shrew-specific clade w...
Intra- and interspecific agonistic encounters in Long-Evans and field-trapped Rattus norvegicus and Rattus rattus showed a consistency in the form and character of attack and defensive behaviors. Colony alpha males exhibited high levels of lateral attack, on-top, and chasing behaviors which resulted in a high percentage of bites on the intruder's back. Bites directed to the back were countered ...
background rodents play a major role in economic losses and public health problems. these animals are considered as natural reservoir hosts of zoonotic cutaneous leishmaniasis (zcl), one of the major health concerns in iran. conclusions the spatial and temporal monitoring of wild rodents will help to predict the potential zoonotic rodent-borne diseases. objectives this research was aimed to stu...
The order Piroplasmida encompasses tick-borne pathogens of veterinary and medical importance positioned in two main families: Babesiidae Theileriidae. Even though previous studies carried out Brazil recorded the occurrence piroplasmid species circulating small mammals, 18S RNA gene sequences were only partially sequenced, preventing assessment their phylogenetic positioning. current study aimed...
Syphacia muris worm burdens were evaluated in the rat Rattus norvegicus of the strains Wistar (outbred), Low/M and AM/2/Torr (inbred), maintained conventionally in institutional animal houses in Brazil. Morphometrics and illustration data for S. muris recovered from Brazilian laboratory rats are provided for the first time since its proposition in 1935.
We amplified and sequenced six complete genomes of a polyomavirus from feral Norway rats (Rattus norvegicus) and from a long-term breeding colony derived from Norway rats. This virus, which is closely related to hamster polyomavirus and murine polyomavirus, may contribute to understanding the evolutionary history of rodent polyomaviruses.
