Abstract：
:A non-toxigenic tox gene-bearing (NTTB) Corynebacterium ulcerans was grown from the wound of a 61-year-old gardener and in a nasal specimen from the patient's asymptomatic dog. The two isolates were similar in terms of antibiogram, multilocus sequence typing (ST341), virulence genes, and only three SNPs were found to differentiate the two NTTB C. ulcerans isolates supporting a zoonotic transmission to or between the patient and his dog. Of interest, we found that the two C. ulcerans isolates, although not expressing the diphtheria toxin tox, possessed 13 out of 14 recently described virulence candidate genes.

杂志文章abstract：:Japanese encephalitis virus (JEV) is an arbovirus belonging to the family Flaviviridae. It is maintained in a zoonotic cycle involving pigs, ardeid birds and Culex species of mosquitoes. Humans are accidental/dead end hosts of JEV infection because they cannot sustain high viral titers. Factors affecting the clinical ...
