PARTICULARITIES OF THE ETIOLOGICAL STRUCTURE OF NOSOCOMIAL INFECTIONS IN HOSPITALS OF ORTHOPEDICS AND TRAUMATOLOGY PROFILE (Abstract): Determination of etiological structure of septic-purulent nosocomial infections (SPNI) in hospitals of orthopedics and traumatology profile. Materials and methods: there were analyzed 2013 strains of microorganisms isolated from the patients with SPNI. Results: ...

-We examined geographic differentiation in mitochondrial (mt) DNA and in morphometric characters among 12 populations of the Sharp-tailed Sparrow (Ammodramus caudacutus) representing all recognized subspecies and geographic regions. Both data sets reveal the existence of two distinct groups of populations, a northern group from the Canadian maritime provinces and Maine, the St. Lawrence Valley,...

BACKGROUND AND OBJECTIVES Resistance among bacterial isolates is the leading cause of increased mortality and morbidity worldwide. Carbapenems once thought to be effective are becoming ineffective mostly due to the emergence of carbapenemase. This study was designed to determine in vitro efficacy of Modified Hodge test for detection of carbapenemase production in Gram negative rods. MATERIAL ...

β-lactams are the most widely used group of antimicrobials. However, increasing resistance to these valuable drugs in uropathogens, mediated principally by β-lactamases, has become a major concern. The present study was undertaken to determine the prevalence of Extended Spectrum β-Lactamase (ESBL) producers in clinical isolates of urine specimens, collected from various healthcare centres acros...

The Mesoamerican bee genus Mexalictus (Hymenoptera: Halictidae: Halictinae) is a group of rare bees which are found at high elevations from southern Arizona (USA) to Panama. The genus is revised using traditional taxonomic approaches. The following twenty one new species are described: M. albofasciatus Dumesh, n. sp., M. anatolii Dumesh, n. sp., M. astriatus Dumesh, n. sp., M. ayalai Dumesh, n....

GR69153, a new parenteral cephalosporin, inhibited 90% of Escherichia coli, Klebsiella oxytoca, Proteus mirabilis, Citrobacter diversus, shigellae, and salmonellae at less than 0.25 micrograms/ml (MIC90). It had activity comparable to those of ceftazidime, cefpirome, cefepime, and E-1040. Against cephalosporinase-producing Enterobacter cloacae, Citrobacter freundii, and Serratia marcescens, MIC...

This paper revises the Afrotropical species of the tribe Eudorylini. The four genera (Claraeola, Clistoabdominalis, Dasydorylas, Eudorylas) present in the Afrotropical Region comprise 77 species (4, 4, 8 and 61 species respectively), 15 of them are new to science: Clistoabdominalis namibiensis, Dasydorylas bodocsi, D. okongoensis, Eudorylas angolae, E. barracloughi, E. brandbergensis, E. femora...

MICs of erythromycin, clarithromycin, and azithromycin for 852 recent clinical isolates were determined by broth microdilution methods. Frequency distribution curves, scattergrams, and regression analyses were used to compare in vitro activities and describe cross-resistance. Clarithromycin was the most active drug against Bacteroides spp. but the least active against Haemophilus influenzae. Az...

OBJECTIVE To determine the aetiological bacterial agents of urinary tract infections, within communities in Kenyatta University, and current resistance levels to commonly available therapeutic agents. DESIGN Cross-sectional survey research design. SETTING Kenyatta University Health Services Clinic, Nairobi. SUBJECTS Outpatients with symptoms of urinary tract infection within the six month...

Augmentin (Beecham Laboratories, Bristol, Tenn.), a combination drug consisting of two parts amoxicillin to one part clavulanic acid and a potent beta-lactamase inhibitor, was evaluated in vitro in comparison with ampicillin or amoxicillin or both for its inhibitory and bactericidal activities against selected clinical isolates. Regression analysis was performed and tentative disk diffusion sus...
