Severity of group B streptococcal arthritis in selected strains of laboratory mice.
The susceptibilities of C3H/HeN, BALB/c, and C57BL/6N mouse strains to group B streptococci (GBS) infection were evaluated. C3H/HeN mice developed severe polyarthitis; mild lesions and no lesions were observed in BALB/c and C57BL/6N mice, respectively. A correlation between the severity of arthritis, the number of GBS in the joints, and local interleukin-6 and interleukin-1beta production was e...
متن کاملAntibiotic susceptibilities of genetically characterized Streptococcus milleri group strains.
Previous studies of the antibiotic susceptibility of Streptococcus milleri group organisms have distinguished among species by using phenotypic techniques. Using 44 isolates that were speciated by 16S rRNA gene sequencing, we studied the MICs and minimum bactericidal concentrations of penicillin, ampicillin, ceftriaxone, and clindamycin for Streptococcus intermedius, Streptococcus constellatus,...
متن کاملGenetic analysis of the porcine group B rotavirus NSP2 gene from wild-type Brazilian strains.
Group B rotaviruses (RV-B) were first identified in piglet feces, being later associated with diarrhea in humans, cattle, lambs, and rats. In human beings, the virus was only described in China, India, and Bangladesh, especially infecting adults. Only a few studies concerning molecular analysis of the RV-B NSP2 gene have been conducted, and porcine RV-B has not been characterized. In the presen...
متن کاملCharacterization of group C and G streptococcal strains that cause streptococcal toxic shock syndrome.
Twelve strains (the largest number ever reported) of group C and G(1) streptococci (GCS and GGS, respectively) that caused streptococcal toxic shock syndrome (STSS) were collected and characterized. Eleven strains were identified as Streptococcus dysgalactiae subsp. equisimilis, and one strain was identified as Streptococcus equi subsp. zooepidemicus. We found that it was the first reported cas...
متن کاملDifferential lung mechanics are genetically determined in inbred murine strains.
Genetic determinants of lung structure and function have been demonstrated by differential phenotypes among inbred mice strains. For example, previous studies have reported phenotypic variation in baseline ventilatory measurements of standard inbred murine strains as well as segregant and nonsegregant offspring of C3H/HeJ (C3) and C57BL/6J (B6) progenitors. One purpose of the present study is t...
