[B Streptococcus and other pathogenic bacteria colonization in hospitals in the Gdańsk Metro Area].

A survey of group B Streptococcus and other pathogenic bacteria colonization was carried out on 658 neonates in 8 neonatal wards of hospitals in the Gdańsk Metro Area and the district of Gdańsk. Out of pathogenic bacteria Haemophilus and enteric bacteria the most frequently were isolated. The percentage of Staphylococcus aureus was relatively low (19.4). The group B Streptococcus frequency in throat was established as 3.8% and ranging from 1.7 to 8.8% in particular wards. In two cases group B streptococcus were not isolated. In probes taken from anus of newborn tested typical enteric flora dominated and E coli and Klebsiella sp were the most frequently encountered. Profile and frequency of bacterial colonization indicated that epidemiological situation in majority of particular wards in similar.

[Susceptibility of bacteria isolated from clinical material to ciprofloxacin].

The aim of the study was to evaluate susceptibility to ciprofloxacin of bacteria species isolated from different specimens of clinical materials. The investigated strains (830) were identified using conventional methods. The antibacterial activity of ciprofloxacin was studied by the method of drug dilution in Mueller-Hinton agar. Among aerobic bacteria, only 5 strains (0.6%) were resistant to ciprofloxacin in concentration 4 micrograms/ml; two belonged to E. coli species, two to S. aureus and one was a Streptococcus group B., Corynebacterium sp. MIC90 = 0.12 microgram/ml turned out to be most resistant, next, Gram-negative rods MIC90 = 0.5 microgram/ml, coagulase-negative and positive staphylococci and Neisseria sp. MIC90 = 1.0 microgram/ml. Enterococcus faecalis and anaerobes were the least susceptible to ciprofloxacin. Their MIC90 was 2 and 16 micrograms/ml respectively. Among 20 anaerobic strains, up to 10 were resistant to ciprofloxacin, mainly from Bacteroides and Clostridium genus.

[Colonization with group B streptococci in neonates and premature infants from selected neonatal departments].

Group B streptococci are considered an important etiological agent of sepsis and meningitis in neonates and, particularly, in premature infants. There is a close correlation between colonization with these bacteria and the frequency of symptomatic infection. It is estimated that symptomatic infections occur in 1.0% of colonised neonates. The purpose of this work was to investigate the frequency of neonate colonization with group B streptococci for determination of the risk of symptomatic infection.

[Group B streptococci as an etiologic agent of infections in adults and their characteristics].

The investigation was performed on 1471 bacteriologically-positive samples of materials derived from patients hospitalized in various hospital wards (mainly gynecology and obstetrics). Group B streptococci were in 10% etiological factors of infections in patients from gynecological and obstetrical wards. These bacteria were isolated in 25% from pus, 15.7% from vaginal smears and in 13.7% from cervix uteri. In urinary tract infections, group B streptococci were present in 10.7% of urine samples with positive bacteriological result. They were also isolated from 8.3% of sperm samples treated because of infertility. Isolated strains of group B streptococci belonged most frequently to following serotypes: Ic, III, R, Ib and II consisting respectively 33.5, 19.3, 12.9, and 11.0% of all strains out of 155 tested serologically. These results demonstrate that group B streptococci are frequently causative in bacterial infections of hospitalized patients.

[Colonization with group B streptococcus in pregnant women taken into the care of unit K and hospitalized in the department of obstetric pathology].

Colonization with group B streptococci (GBS) in 714 pregnant women was investigated. Among 232 were hospitalised in department of pathological pregnancy and 512 were under ambulatory control. In 13.4% of hospitalised patients and 2.8% healthy pregnant women the colonization of vagina or throat with GBS was stated. The greatest percentage of vagina colonization was found in patients hospitalised in connection with gestosis or because of abortions, premature delivery and inanimate fetus. No correlation was found between range of GBS colonization and trimester of pregnancy. Almost all GBS strains proved to be susceptible for commonly used antibiotics but resistant to biseptol (88.2%). Patients of hospitalised group were more often colonized not only GBS but also other potentially pathogenic microorganisms.
