Molecular detection of Giardia duodenalis and Cryptosporidium spp. from stray dogs residing in monasteries in Bangkok, Thailand.

Both Cryptosporidium spp. and Giardia duodenalis are enteric protozoan parasites that infect a wide variety of domestic animals as well as humans worldwide, causing diarrheal diseases. Giardia duodenalis assemblages C and D are specific to canine hosts and zoonotic assemblages A and B are also found in dogs as a reservoir host.

Detection of Babesia vogeli in stray cats of metropolitan Bangkok, Thailand.

The combination of a rapidly growing stray animal population and the lack of animal control in Bangkok has resulted in a unique opportunity to evaluate the potential role of companion animals as sentinels and reservoirs of infectious diseases, including several of those caused by vector-borne parasites. The purpose of this study was to determine the prevalence and factors associated with the distribution of Babesia species infections among stray cats in Bangkok. Blood samples were collected from 1490 stray cats residing in 140 monasteries of 50 metropolitan districts of Bangkok, and assayed with light microscopy and PCR for evidence of Babesia spp.
