Background. Antibiotic resistance is a worldwide problem that is the main cause of the increase in the number of purulent-inflammatory diseases and postsurgical complications. Aim. The aim of the present study was to monitor antibiotic resistance of microorganisms isolated in the course of microbiological study in otorhinolaryngological and surgical patients of the outpatient department of a single preventive health institution. Material and methods. A statistical analysis of the results of microbiological studies, excretions of patients undergoing outpatient treatment in surgical and otorhinolaryngological departments of outpatient clinic No1 of the state budget institution «City Clinical Hospital No 7» of Tver is presented. We processed 280 findings of microbiological studies of ear, nose, pharynx and wound surface cultures for 2019. Results and discussion. It was found that the spectrum of dominant microorganism species in 2019 detected during swabbing of surgical and otorhinolaryngological patients treated in the outpatient clinic included gram-negative Escherichia coli and Klebsiella pneumonia and gram-positive Staphylococcus aureus and Streptococcus pyogenes microorganisms. Among the microorganisms presented, strains with multiple resistance to the action of antimicrobial drugs were identified. According to the total number of resistant microorganisms it was found that among antibacterial drugs, antibiotics of Aminopenicillin class, including those protected by protease inhibitors, as well as fluoroquinolones of the 2nd generation have the lowest clinical efficacy in the given medical institution. Conclusion. The findings of the present study indicate a rapid rate of spread of resistance genes among nosocomial strains of microorganisms, which necessitates continuous monitoring of antibiotic sensitivity by various specific laboratory methods. The results of laboratory studies should be used when prescribing antibiotic therapy for a particular patient, and the results of this study should be considered when selecting an empirical antibiotic, since they reflect the resistance of the most common pathogens. Key words: antibiotic resistance, antibiotics, cephalosporins, fluoroquinolones.

In this study, the aim was to investigate the discriminatory power of molecular diagnostics based on mNGS and traditional 16S ribosomal RNA PCR among Nocardia species. A total of fourteen clinical isolates from patients with positive Nocardia cultures and clinical evidence were included between January 2017 and June 2020 in HeNan Provincial People’s Hospital. DNA extraction and 16S rRNA PCR were performed on positive cultures, and pathogens were detected by mNGS in these same samples directly. Among the 14 Nocardia isolates, four species were identified, and N. cyriacigeorgica (8 cases) is the most common species. Twelve of the 14 Nocardia spp. isolates were identified by the two methods, while two strains of N. cyriacigeorgica were not identified by mNGS. All tested isolates showed susceptibility to trimethoprim-sulfamethoxazole (SXT), amikacin and linezolid. Apart from Nocardia species, other pathogens such as Acinetobacter baumannii, Klebsiella pneumonia, Aspergillus, Enterococcus faecalis, Human herpesvirus, etc., were detected from the same clinical samples by mNGS. However, these different pathogens were considered as colonization or contamination. We found that it is essential to accurately identify species for determining antibiotic sensitivity and, consequently, choosing antibiotic treatment. 16S rRNA PCR was useful for identification of nocardial infection among species, while this technique needs the clinicians to make the pre-considerations of nocardiosis. However, mNGS may be a putative tool for rapid and accurate detection and identification of Nocardia, beneficial for applications of antimicrobial drugs and timely adjustments of medication.

Relevance. Microbiological monitoring in medical organizations is an essential part of ensuring epidemiological safety in the provision of medical care. The study of the sensitivity of pathogens to antibacterial drugs allows us to reasonably approach the prescription of empirical therapy and form a form of antibacterial agents for medical organization. The purpose of the work was to study the species composition of pathogens of generalized purulent septic infections (GPSI) in a children's multidisciplinary hospital and determine their resistance to antibacterial drugs. Materials and methods. Analysis of microbiological analysis data of material taken from patients with GPSI treated in children's multidisciplinary hospital in the period 2013-2018 was carried out. A total of 572 cultures were studied. Results. It was found that the largest specific gravity in the structure of GPSI was occupied by gram-negative microorganisms, the proportion of which significantly decreased from 73.0% in 2013 to 48.1% in 2018. Gram-positive microorganisms were found in 27.0 ± 8.1% cases, while a significant increase in the proportion of fungi from 5.4 to 30.7% was observed. The antibiotic resistance of the main pathogens has been studied. Among non-fermenting gram-negative bacteria, the highest (p < 0.05) multi-resistivity indicator was found in Acinetobacter baumannii (50.0 ± 6.8%). Enterococcus, having high natural resistance to a number of antibiotic groups, leave the possibility of effective action of the preparation of the group of glycopeptides (vancomycin) against Enterococcus faecium. Conclusions. High pathogens to applied antibacterial preparations is shown. The obtained data make it possible to form an up-to-date form of antimicrobial drugs for use in children's hospitals, to develop measures that inhibit the development of resistance in pathogens of purulent-inflammatory diseases.

Objectives: The study aimed to determine the prevalence of otitis media (OM)-associated bacterial flora of asymptomatic people living with HIV (PLH) on antiretroviral therapy (ART) and assess antibiotic resistance profiles of the bacteria. Methodology: Ear secretion specimens were collected by syringe or cotton swabs. Isolated bacteria were subjected to antibiotic sensitivity tests. Results: Of 290 recruited PLH, 81.7% were females and 18.3% males; their CD4+ counts ranged from 0 to 1770. Staphylococcus aureus, Klebsiella pneumonia, and Escherichia coli were the predominant bacteria. High antibiotic resistance was detected on Streptococcus pyogenes and Streptococcus pneumoniae. The prevalence rate of OM-associated bacteria (OAB) was 93.4%, and majority of the bacteria were resistant to multiple antibiotics. Linear association between the prevalence of OAB with both duration of ART and CD4+ counts was observed. Conclusion: High prevalence rates of OAB and antibiotic resistance were observed. Negative correlation between CD4+ counts and prevalence of OAB was revealed.

Today the one of most important medical-social problems is a growing antibiotic resistance of opportunistic infectious agents. Aim of research: the dynamic observance of antibiotic resistance of opportunistic pathogens – infectious agents of genitourinary tracts under conditions of venereological clinic. The study included 2205 patients with inflammatory diseases of genitourinary tract, who were on the stationary treatment at the department of venereology of SI “IDV NAMS of Ukraine”. Bacteriological studies for isolation of conventionally pathogenic microorganisms with determination of sensitivity of separated laboratory strains to antibacterial drugs of the different groups were carried out using the methods of classic bacteriology. It was demonstrated, that the composition of microbiocenosis of genitourinary tract in patients with infections, caused by conventionally pathogenic microorganisms was characterized by the prevalence of aerobic representatives of Enterobacteriaceae and Staphylococcaceae families that formed associations both between each other and with representatives of other taxonomic groups. The analysis of antibiotic sensitivity of separated strains testifies to the necessity of permanent microbiological monitoring of opportunistic infectious agents for elaborations of the regimes of rational antibacterial therapy.

Globally, antibiotic resistance in bacteria isolated from neonatal sepsis is increasing. In this cross-sectional study conducted at a medical college teaching hospital in Nepal, we assessed the antibiotic resistance levels in bacteria cultured from neonates with sepsis and their in-hospital treatment outcomes. We extracted data of neonates with sepsis admitted for in-patient care from June 2018 to December 2019 by reviewing hospital records of the neonatal intensive care unit and microbiology department. A total of 308 neonates with sepsis were admitted of which, blood bacterial culture antibiotic sensitivity reports were available for 298 neonates. Twenty neonates (7%) had bacteriologic culture-confirmed neonatal sepsis. The most common bacterial species isolated were Staphylococcus aureus (8), followed by coagulase-negative Staphylococcus (5). Most of these bacteria were resistant to at least one first-line antibiotic used to manage neonatal sepsis. Overall, there were 7 (2%) deaths among the 308 neonates (none of them from the bacterial culture-positive group), and 53 (17%) neonates had left the hospital against medical advice (LAMA). Improving hospital procedures to isolate bacteria in neonates with sepsis, undertaking measures to prevent the spread of antibiotic-resistant bacteria, and addressing LAMA’s reasons are urgently needed.

SUMMARYThis study is a part of the surveillance study on childhood diarrhoea in the Andaman and Nicobar Islands; here we report the drug resistance pattern of recent isolates ofShigellaspp. (2006–2011) obtained as part of that study and compare it with that ofShigellaisolates obtained earlier during 2000–2005. During 2006–2011, stool samples from paediatric diarrhoea patients were collected and processed for isolation and identification ofShigellaspp. Susceptibility to 22 antimicrobial drugs was tested and minimum inhibitory concentrations were determined for third-generation cephalosporins, quinolones, amoxicillin-clavulanic acid combinations and gentamicin. A wide spectrum of antibiotic resistance was observed in theShigellastrains obtained during 2006–2011. The proportions of resistant strains showed an increase from 2000–2005 to 2006–2011 in 20/22 antibiotics tested. The number of drug resistance patterns increased from 13 in 2000–2005 to 43 in 2006–2011. Resistance to newer generation fluoroquinolones, third-generation cephalosporins and augmentin, which was not observed during 2000–2005, appeared during 2006–2011. The frequency of resistance inShigellaisolates has increased substantially between 2000–2006 and 2006–2011, with a wide spectrum of resistance. At present, the option for antimicrobial therapy in shigellosis in Andaman is limited to a small number of drugs.

Fournier's Gangrene

Background: Fournier's gangrene (FG) is a devastating disease that is characterized by necrotizing fasciitis of the perineal, genital, or perianal region. Broad-spectrum antibiotics are the key component of its treatment. However, there is paucity of data regarding the optimal empirical antibiotic therapy for FG. Materials and Methods: Data from patients who underwent surgery for FG was retrieved from a prospectively collected departmental FG database. Demographics, clinical characteristics, causative pathogens and drug susceptibility/resistance were evaluated. Outcome was also assessed in terms of mortality. Results: Fifty patients with a median age of 58.5 (40-83) years were included. The perianal region and scrotum (88%) were the most commonly affected. Diabetes mellitus (DM) was the most common comorbidity (92%). The median time to onset of symptoms was 7 (2-15) days, and the median duration of hospital stay was 22 (4-65) days. Ventilator requirement was required in 15 (30%) patients. The median UFGSI score was 9.5 (3-15). The overall mortality rate was 26%. A positive growth was found in specimen cultures of 48 (96%) patients. The median number of bacterial strains that grew in the cultures was 3 (0-10). Amikacin was the antibiotic with the highest frequency of sensitivity (74%), while the highest resistance was observed against ampicillin-sulbactam (64%). Escherichia coli was the most common microorganism (68%). Acinetobacter baumannii and Klebsiella pneumonia were signicantly more common in patients who required mechanical ventilation. The mortality rate was 26%. An Uludag Fournier's Gangrene Severity Index (UFGSI) score of > 9.5 and ventilatory support requirement were factors associated with an increased rate of mortality. Acinetobacter baumannii was the only microorganism which was associated with an increased mortality rate. Conclusion: Causative pathogens in FG appeared to be shifting; thus, empirical antibiotic treatment for this disease should be modied. We recommend 3rd-generation cephalosporin, metronidazole and amikacin for empirical therapy.
