SYNOPSIS Strains of Gram-positive, catalase-positive, coagulase-negative cocci isolated from urine specimens were classified by the system of Baird-Parker (1963). Urinary infections attributed to instrumentation or pathological abnormalities of the urinary tract were caused almost entirely by various Staphylococcus subgroups. These showed a wide range of antibiotic sensitivities, unrelated to s...
A screening study of the presence of metallo-beta-lactamases (IMP and VIM types and SPM-1) in isolates from different nonhospital sources was conducted, and it revealed the presence of bla(VIM-2), associated with the In58 class 1 integron, in two unrelated Pseudomonas aeruginosa strains from aquatic habitats. The results suggest that the hospital setting was the possible origin of these bla(VIM...
Theories of language production need to account for how speakers produce prosodic structure. Very few models have addressed the role of prosodic phrasing in speech planning, and little experimental work examining this question has been conducted so far. Four studies designed to investigate the effect of phrase length and prosodic phrasing on speech planning are presented. The first experiment e...
Work is frequently on the minds of employees—even during evenings, weekends, and vacations. The present study first comprehensive meta-analysis off-job work-related thoughts (WRTs; i.e., employees have about work when they are not at work). We were particularly interested in comparing positive negative (PWRTs NWRTs; positive/negative experiences or characteristics) to each other WRT constructs,...
Acinetobacter baumannii is an opportunistic pathogen, causing infections mainly in patients in intensive care units where the extensive use of antimicrobial agents can select for the emergence of multiresistant strains. In fact, since strains resistant to all antimicrobial agents have been reported, A. baumannii is considered the paradigm of multiresistant bacteria. Both acquired and intrinsic ...
Attenuated strains of Salmonella have been used effectively as vaccines against typhoid fever. We have investigated the use of such strains to deliver cloned antiphagocytic virulence determinants of unrelated bacteria. The aroA strain of S. typhimurium SL3261 was transformed with a low-copy plasmid vector pMK207, which contains the cloned gene spm5 encoding streptococcal M protein, the major vi...
Owing to differences in histocompatibility genes, most transplanted mouse tumors grow pro gressively, as a rule, only in animals of their strain of origin. In mice of genetically unrelated strains they usually grow for a variable period of time and subsequently regress. As the number of serial transfers increases, some transplantable tumors, besides killing 100 per cent in their own strain, ac ...
We describe the use of two insertion sequence elements (ISFtu1 and ISFtu2) in Francisella tularensis to type strains by restriction fragment length polymorphism (RFLP). The RFLP profiles of 17 epidemiologically unrelated isolates were determined and compared. Our results showed that RFLP profiles can be used to assign F. tularensis strains into five main groups corresponding to strains of F. tu...
We examined the antimicrobial susceptibilities of 85 Neisseria gonorrhoeae isolates, classified according to the presence of amino acid substitutions in the GyrA and ParC proteins, to 12 fluoroquinolones and 7 other antibiotics. Sitafloxacin and HSR-903 showed excellent activity against N. gonorrhoeae, including strains with both GyrA and ParC substitutions. Among the strains with various GyrA ...
Mycoplasma strains (B1, B2, CS, and S1A) were isolated from the saliva of normal cats. These were compared with a strain (CO) isolated from the eye of a cat with severe conjunctivitis. On the basis of morphology, biochemical reactions, and antigenic composition, two distinct species were recognizable. Strains CO, B1, and B2 were antigenically unrelated to the other species tested; strains CS an...
