Here we present the draft genome of an actinobacterium, Brachybacterium muris UCD-AY4. The assembly contains 3,257,338 bp and has a GC content of 70%. This strain was isolated from a residential bath towel and has a 16S rRNA gene 99.7% identical to that of the original B. muris strain, C3H-21.

1. The virus of Bartonella muris anemia of splenectomized rats may be transmitted to normal young unoperated rats and rabbits. This confirms the observations of Ford and Eliot. 2. Trypanosoma lewisi infections in normal adult rats are accompanied by an anemia most marked at the height of the infection and the appearance of Bartonella muris bodies in the red blood cells. 3. In young rats Trypano...

AIMS The research was initiated to confirm earlier ultraviolet (u.v.) light inactivation studies performed on Giardia cysts using excystation as the viability indicator. Following this, a comparison of in vitro excystation and animal infectivity was performed for assessing cyst viability after exposure to low-pressure u.v. irradiation. METHODS AND RESULTS Cysts of Giardia muris were inactivat...

The effect of Giardia muris infection on the diarrheal response and gut mucosal antibody response to cholera toxin was examined in mice. The results obtained showed that the fluid accumulation in intestinal loops exposed to cholera toxin was increased in mice infected with a low number (5 X 10(4) ) of G. muris cysts compared with the response in noninfected mice. This effect was associated with...

Trichuris muris resides in intimate contact with its host, burrowing within cecal epithelial cells. However, whether the enterocyte itself responds innately to T. muris is unknown. This study investigated for the first time whether colonic intestinal epithelial cells (IEC) produce cytokines or chemokines following T. muris infection and whether divergence of the innate response could explain di...

The mange mite Notoedres muris is reported from a new host, the marsh rat (Holochilus brasiliensis) from Argentina. The infection involved alopecia and encrustations on the ears and face, and was treated successfully by a subcutaneous injection of ivermectin. The new record suggests that Notoedres muris has become self-maintaining within this marsh rat population.

Syphacia muris worm burdens were evaluated in the rat Rattus norvegicus of the strains Wistar (outbred), Low/M and AM/2/Torr (inbred), maintained conventionally in institutional animal houses in Brazil. Morphometrics and illustration data for S. muris recovered from Brazilian laboratory rats are provided for the first time since its proposition in 1935.

We report here the complete genome sequence of Ehrlichia muris strain AS145(T), which was isolated from a wild mouse in 1983 in Japan. E. muris establishes persistent infections in laboratory mice and is widely used as a surrogate pathogen in a murine model of ehrlichiosis.
