Aim. Study of frequency, the characteristic of lower respiratory tract infections, and results of microbiological researches of biomaterial at HIV-positive patients. Materials and methods. Materials of the Infectious hospital No. 1 of Omsk in 5 years (2012 - 2016) were used. Results. From the treated 1926 HIV-positive patients, lower respiratory tract infections occurred in 538 patients. 45,2% at which lethality was 18,1% fell to the share of bacteriemic pneumonia. The analysis of results of microbiological researches of biomaterials at HIV-positive patients was carried out. In a sputum Staphylococcus aureus, Klebsiella pneumoniae, Enterococcus faecalis and other microorganisms was most often allocated. Streptococcus viridans and mushrooms of the sort Candida were a frequent find in biomaterial. Conclusion. The received results demand further researches for comparison of clinicoradiological implications and result of a microbiological research of biomaterials of HIV-positive patients.

Lower respiratory tract infections (LTRIs) are responsible for the vital causes of morbidity and mortality in all ages. In recent years, antibiotic resistance among respiratory pathogens is increasing emergently. The present study aimed to find out the bacterial etiology of LRTIs in Bangladesh and to update the clinicians about the current scenario of antibiotic resistance in lower respiratory tract infections. A total 64 bacterial pathogens from 100 patients with LRTIs were isolated from sputum specimens from a teaching hospital in Savar, Bangladesh between July- 2014 to June- 2015. The sputum specimens received within this year were subjected to analysis with microscopy, culture and susceptibility testing using conventional bacteriologic methods. Out of 100 processed sputum samples 64 (64%) cases had established bacterial etiology. Staphylococcus aureus (57.81%) was found to be the predominant organism in LRTIs followed by Streptococcus pneumonia (25%), Klebsiella and Pseudomonas species. Males (64.06%) were found to be more susceptible to LRTIs than that of females (35.93%). In antimicrobial susceptibility testing, grampositive organisms showed maximum sensitivity to imipenem (94.6%), meropenem (97.3%) and cefotaxime (75%). The resistance pattern varied for different organisms. Staphylococcus aureus isolates were mostly resistant to amoxicillin and ceftazidime (89.2%), whereas, Streptococcus pneumonia was to ceftazidime, amoxicillin and cotrimoxazole (81.2%). In case of gram negative isolates, Klebsiella sp. was mostly resistant to ceftriaxone, ceftazidime and amoxicillin (100%). Escherichia coli were resistant to amoxicillin, cotrimoxazole and vancomycin (100%). Therefore, appropriate identification of the causative organisms and their antibiotic resistance is crucial for right choice of antibiotic therapy in LRTIs.Bangladesh Pharmaceutical Journal 19(1): 85-91, 2016
