We analyzed the susceptibility of 10 AKXD recombinant inbred (RI) mouse strains to lymphomas. These strains were derived from crosses of AKR/J, a highly lymphomatous strain, and DBA/2J, a weakly lymphomatous strain. Of the 10 strains analyzed, nine showed a high incidence of lymphoma development. As with the other 13 AKXD strains analyzed previously (M. L. Mucenski, B. A. Taylor, N. A. Jenkins,...

1 We have compared nine Enterococcus faecalis strains with E. faecalis V583 (V583), for 2 which a complete genome sequence and a genome-wide microarray is available. The strains 3 we have used in this study (the test strains) originated from various environments; 4 veterinarian, food, and environmental isolates, as well as lab strains. Comparative genomic 5 hybridization using microarrays (CGH)...

1. Squirrels and chipmunks were found to be susceptible to infection with the Spironema recurrentis of North China, but no relapses occurred in normal animals. 2. Splenectomy caused an increase in the intensity of the infection and the appearance of one or two relapses. 3. By inoculating splenectomized squirrels with a single human strain of spirochetes, six different strains were produced as a...

conclusions: considering the low rate of ceftriaxone resistance amongst isolated pneumcocci.in this study, only ceftriaxone treatment of adult patients with invasive pneumococcal infections (other than cns infections) is sufficient; but pediatric patients and patients with cns infections should be treated with ceftriaxone and vancomycin. apparently, diminution of vancomycin use can be resulted ...

Mutations related to streptomycin resistance in the rpsL and rrs genes are well known and can explain about 70% of this phenotypic resistance. Recently, the gidB gene was found to be associated with low-level streptomycin resistance in Mycobacterium tuberculosis. Mutations in gidB have been reported with high frequency, and this gene appears to be very polymorphic, with frameshift and point mut...

Sixty-two strains of Gibberella pulicaris (anamorph: Fusarium sambucinum) from diseased plants and from soil were tested for tolerance of the furanocoumarin xanthotoxin in vitro. Twenty-one (88%) of the plant-derived strains and two (5%) of the soil-derived strains were highly tolerant ofxanthotoxin. Sixteen selected strains were tested further against 16 furanocoumarins or furanocoumarin precu...

Bacteriol. 90:108-115. 1965.-A study of several wild cross-transformable strains of Bacillus subtilis revealed differences in the resistance of their spores to X rays. Closer study of two such strains reveale...

Salmonella enterica serovar Typhimurium strains of particular phage types, such as DT104, U302, DT120, DT193, and nontypable strains, are often characterized by resistance to multiple antibiotics. This antibiotic resistance can be caused by the presence of the integrons, transposons, Salmonella genomic island 1 (SGI1), or conjugative plasmids. In this study we were interested in the relative co...

BACKGROUND Leptospirosis is one of the most important neglected tropical infectious diseases worldwide. Icterohaemorrhagiae has been throughout recent history, and still is, the predominant serogroup of this pathogen in China. However, very little in detail is known about the serovars or genotypes of this serogroup. METHODOLOGY/PRINCIPAL FINDINGS In this study, 120 epidemic strains from five ...
