Composition of gut microbiota and its correlations with neurological, intestinal, cardiovascular and metabolic diseases
Acta Microbiol Immunol Hung. 2023 Nov 8. doi: 10.1556/030.2023.02134. Online ahead of print.ABSTRACTThe intestinal microbiota is a microenvironment that has been the subject of studies for several decades. Over time, it has been reconsidered as a possible cofactor of multiple acute and chronic human diseases. In fact, alterations of the intestinal bacterial flora have been found in various neurological diseases. There are three modes of interaction between the intestinal microbiota and the gut-brain-axis: chemical signals, neural pathways and immune system. Even at the gastrointestinal level, the gut microbiota plays certa...

Molecular epidemiology and antimicrobial resistance of Haemophilus influenzae isolates from otitis media in Bulgaria
Acta Microbiol Immunol Hung. 2023 Nov 8. doi: 10.1556/030.2023.02126. Online ahead of print.ABSTRACTHaemophilus influenzae is one of the main bacteria responsible for otitis media (OM) among children worldwide. We aimed to estimate the distribution of encapsulated and non-capsulated variants (NTHi), biotypes, antibiotic susceptibility, and molecular epidemiology of H. influenzae isolates recovered from pediatric OM cases in Bulgaria.Capsule detection was done by PCR for bexB gene, absent in NTHi. All encapsulated strains were subjected to PCR serotyping. MIC susceptibility testing was performed according to the criteria of...

Investigation of carbapenem-resistant Enterobacterales isolates at a tertiary laboratory in Pretoria, South Africa
This study aimed to investigate phenotypic and genotypic characteristics of carbapenem-resistant Enterobacterales isolates (CRE) at a tertiary laboratory in South Africa. A total of 99 CRE isolates were collected between 2019 and 2021. Carbapenemase production was tested using modified carbapenem inhibitory method. Colistin susceptibility testing was performed using the ComASP™ Colistin broth microdilution method. Conventional PCR assays were conducted for detection of mcr-1 gene and common carbapenemase genes (blaVIM, blaNDM, blaIMP, blaKPC, blaOXA-23, blaOXA-51 and blaOXA-48). Rep-PCR assay was conducted to determine t...

Antimicrobial veterinary drug sale pattern in correlation with critically important antimicrobials for human use: A five-year study in Montenegro
Acta Microbiol Immunol Hung. 2023 Oct 30. doi: 10.1556/030.2023.02116. Online ahead of print.ABSTRACTAntimicrobial resistance (AMR) poses a significant threat in veterinary medicine due to the excessive and inappropriate use of antimicrobial agents, compromising the effectiveness of these drugs. To combat AMR, the collection of data on the consumption of antibiotics is paramount, as there is a well-established connection between antibiotic use and AMR in both humans and food-producing animals. Hence, the current study aimed to generate measurable data concerning the sales patterns of antimicrobial drugs used in animal trea...

Genetic diversity and biofilm formation of invasive and noninvasive Streptococcus agalactiae isolates: Emergence of hypervirulent CC19 strains in Tehran, Iran
Acta Microbiol Immunol Hung. 2023 Oct 25. doi: 10.1556/030.2023.02085. Online ahead of print.ABSTRACTThe prevalence of Streptococcus agalactiae infections in adult populations is increasing. The current study aimed to characterize the genetic features of S. agalactiae strains responsible for different infections. A cross-sectional study was performed on 65 S. agalactiae strains (30 invasive and 35 noninvasive) isolated from non-pregnant women. All S. agalactiae isolates were confirmed by atr and dltS PCR assays. Antibiotic susceptibility patterns were determined using the disk diffusion method. Biofilm production was inves...
