Streptococcus merionis sp. nov., isolated from Mongolian jirds (Meriones unguiculatus)

The Effect of Diethylcarbamazine on Microfilariae of Brugia pahangi in Mongolian Jirds (Meriones unguiculatus)

Diethylcarbamazine (DEC) was effective in reducing microfilarial densities of Brugia pahangi in Mongolian jirds (Meriones unguiculatus) when it was administered intraperitoneally at the daily dosage of 300 mg/kg of body weight either for 5 consecutive days or every 3 days for 43 days with the total of 15 doses. The latter treatment scheme seemed to be more effective than the former, suggesting ...

Streptococcus plurextorum sp. nov., isolated from pigs.

Biochemical and molecular genetic studies were performed on an unknown Gram-positive, catalase-negative, coccus-shaped organism isolated from clinical samples from pigs. On the basis of the results of cellular morphological and biochemical tests, the organism was identified as a streptococcal species. 16S rRNA gene sequence comparisons confirmed its identification as a member of the genus Strep...

Tyrosinase (Tyr) Gene Mutation in Albino Mongolian Gerbil (Meriones unguiculatus)

Tyrosinase is encoded by the Tyr (c or albino) locus and is the key enzyme in pigment biosynthesis. Loss of function of this enzyme caused by gene mutation results in albinism. Most cases of albinism are caused by missense mutations of tyrosinase. Albino mutations in Tyr have been identified in various animals, including human, mouse, rat, rabbit, cattle, cat, and ferret, but not in gerbil. We ...

The somatic chromosomes of the Mongolian gerbil (Meriones unguiculatus).

Streptococcus orisasini sp. nov. and Streptococcus dentasini sp. nov., isolated from the oral cavity of donkeys.

Four Gram-positive, catalase-negative, coccoid isolates that were obtained from donkey oral cavities formed two distinct clonal groups when characterized by phenotypic and phylogenetic studies. From the results of biochemical tests, the organisms were tentatively identified as a streptococcal species. Comparative 16S rRNA gene sequencing studies confirmed the organisms to be members of the genu...
