[Beta-lactamases of clinical isolates of Enterobacteriaceae family].

Among 62 clinical strains of enterobacteria, isolated from intestinal tract, representatives of genus Escherichia made--67.4%, Klebsiella--4.84%, Citrobacter--4.

[Isolation frequency and spectrum of sensitivity to antifungal preparations of vulvovaginal candidiasis pathogens].

The conducted microbiological examination of 362 women of reproductive age has shown the availability of vulvovaginal candidiasis in 282 of them. The following representatives of the genus Candida were isolated from the urogenital tract of women: C. albicans (53%), C.

[Composition of microflora and antibiotic sensitivity of bacteria of the women urogenital tract].

A microbial landscape of the urogenital tract in 798 women of reproductive age with various inflammatory diseases of urogenital organs has been investigated. It was fixed, that in 57% of cases the microflora of genitalias of the examined women was presented by associations of aerobic and anaerobic agents. The following associations were distinguished: staphylococci-Bacteroides fragilis (34%), enterobacteria-Bacteroides melaninogenicus (24%), enterobacteria-Anaerobe cocci (15%), staphylococci-B.

[Convertible energy sources in Neisseria gonorrhoeae].

Availability of two major sources of convertible energy in gonococci--the intracellular pool of ATP and electrochemical potential of hydrogen ions--has been established. ATP synthesis occurs when inducing membrane potential by creation of K+ gradient with presence of valinomycin and when inducing the proton gradient. Transmembrane difference of electric potentials has been determined which changes within 103-145 mV under the increase of pH from 5.
