No evidence for sylvatic cycles of chikungunya, dengue and Zika viruses in African green monkeys (Chlorocebus aethiops sabaeus) on St. Kitts, West Indies.

Background: Dengue, chikungunya and Zika viruses (DENV, CHIKV and ZIKV) are transmitted in sylvatic transmission cycles between non-human primates and forest (sylvan) mosquitoes in Africa and Asia. It remains unclear if sylvatic cycles exist or could establish themselves elsewhere and contribute to the epidemiology of these diseases. The Caribbean island of St.

Whole genome analysis provides evidence for porcine-to-simian interspecies transmission of rotavirus-A.

We report here whole genome analysis of a porcine rotavirus-A (RVA) strain RVA/Pig-wt/KNA/ET8B/2015/G5P[13] detected in a diarrheic piglet, and nearly whole genome (except for VP4 gene) analysis of a simian RVA strain RVA/Simian-wt/KNA/08979/2015/G5P[X] detected in a non-diarrheic African green monkey (AGM) on the island of St. Kitts, Caribbean region. Strain ET8B exhibited a G5-P[13]-I5-R1-C1-M1-A8-N1-T7-E1-H1 genotype constellation that was identical to those of Brazilian porcine RVA G5P[13] strains RVA/Pig-wt/BRA/ROTA01/2013/G5P[13] and RVA/Pig-wt/BRA/ROTA07/2013/G5P[13], the only porcine G5P[13] RVAs that have been analyzed for the whole genome so far.

Nocardia cyriacigeorgica as the causative agent of mandibular osteomyelitis (lumpy jaw) in a cat.

An unusual case of osteomyelitis caused by Nocardia cyriacigeorgica infection and resulting in mandibular osteomyelitis and cellulitis (lumpy jaw) is described in a young cat. A 1-cm hard nodular mass was an incidental finding in the right mandible of a 14-month-old cat during routine physical examination. The lesion was fast growing, reaching up to 6 cm in its largest dimension over a 5-week period.
