A novel adenovirus potentiates the species jump of Chlamydophila psittaci from birds to man, causing atypical pneumonia (psittacosis). Viruses, in addition to jumping the species barrier themselves, now are helping other bacteria to do the same: is this the beginning of the age of microbes? Continue reading Novel Psittacine Adenovirus Responsible for Potentiating Zoonotic Psittacosis Outbreak: Emerging Co-Infections
The Porcine Epidemic Diarrhea virus (PEDv) first struck the US coasts in April 2013, leaving public health and veterinary doctors puzzled because they could not figure out how it arrived across the ocean despite stringent measures on animal import.

In a recent article published in the American Journal of Tropical Medicine and Hygiene, it has been postulated that the common bedbug (Cimex lectularius) may have potential to act as a vector for the spread of Trypanosoma cruzi, which causes Chagas disease. In this study, the authors injected the causative agent into mice and then made the bedbugs feed on the mice. The authors then show … Continue reading Bed Bugs: Potential Vectors for Chagas Disease?

The diagnosis was made at necropsy of the dead cattle and following confirmation, a first report has been forwarded to the OIE. From the epidemiological summary of the … Continue reading Anthrax Outbreak in Cattle in Croatia
