Avian and human influenza A virus receptors in trachea and lung of animals.

Background: Influenza A viruses are capable of crossing the specific barrier between human beings and animals resulting in interspecies transmission. The important factor of potential infectivity of influenza A viruses is the suitability of the receptor binding site of the host and viruses. The affinities of avian and human influenza virus to bind with the receptors and the distributions of receptors in animals are different.

Coinfection of Leptospira spp and Toxoplasma gondii among stray dogs in Bangkok, Thailand.

Leptospirosis and toxoplasmosis are zoonotic diseases with global importance. Asymptomatic animals harboring these pathogens may act as carriers to other animals including humans. The objective of this study was to investigate the seroprevalence of Leptospira and Toxoplasma infections in stray dogs in Bangkok.

Identification of the Actinobacillus pleuropneumoniae serotype using PCR based-apx genes.

Actinobacillus pleuropneumoniae (A. pleuropneumoniae) is an important swine respiratory disease pathogen, which has at least 15 serotypes. There are several techniques for the serotyping of A.
