Mycobacterium leprae Infection in a Wild Nine-Banded Armadillo, Nuevo León, Mexico.

Nine-banded armadillos (Dasypus novemcinctus) are naturally infected with Mycobacterium leprae and are implicated in the zoonotic transmission of leprosy in the United States. In Mexico, the existence of such a reservoir remains to be characterized. We describe a wild armadillo infected by M.

[Molecular detection of hepatitis E virus in pig livers destined for human consumption in the state of Nuevo Leon, Mexico].

Objective: Molecular detection of HEV in pig livers destined for human consumption in Nuevo Leon, Mexico.

Materials And Methods: 87 livers were collected from pigs slaughtered in TIF and 40 livers from butchers. A 212 pb fragment of HEV ORF2 gene was amplified by semi-nested RT-PCR.

Prevalence of antibodies to Theileria equi and Babesia caballi in horses from northeastern Mexico.

The objective of this study was to obtain an estimate for seroprevalences of Theileria equi (Babesia equi) and Babesia caballi in horses from northeastern Mexico. Sera were collected in spring of 2007 in 248 clinically healthy horses used for different purposes. Antibodies were detected by the indirect immunofluorecent technique.

Genetic and antigenic characterization of novel pestivirus genotypes: implications for classification.

Currently, the genus Pestivirus comprises the four approved species Bovine viral diarrhea virus 1 (BVDV-1), BVDV-2, Classical swine fever virus (CSFV), and Border disease virus (BDV) and one tentative fifth species represented by a single strain (H138) isolated from a giraffe in Kenya more than 30 years ago. To further address the issue of heterogeneity of pestiviruses we have determined the entire N(pro) and E2 coding sequences for several new pestivirus isolates. Interestingly, phylogenetic analysis revealed that one pestivirus isolated in the 1990s in Africa is closely related to strain H138.
