Pediatric tuberculosis in Mexico and the COVID-19 phenomenon: Past and present
Acta Microbiol Immunol Hung. 2024 Feb 15. doi: 10.1556/030.2024.02212. Online ahead of print.ABSTRACTIn endemic regions, tuberculosis in children constitutes a bigger fraction of total cases as compared to those in low endemic regions, regardless of the implications, this phenomenon has been historically neglected. Pediatric tuberculosis has an insidious onset and quickly develops into disseminated disease and the young are at a special risk for dissemination. Some studies suggest that measures to contain adult tuberculosis are not enough to manage tuberculosis in children, meaning that pediatric tuberculosis needs dedicat...

Prevalence and antimicrobial resistance of bacterial enteropathogens in Crete, Greece, during 2011-2022
This study investigated the epidemiology and the antibiotic susceptibility of bacterial enteropathogens among diarrheal patients of all ages in Crete, Greece during 2011-2022. Stool specimens were tested by conventional cultural methods for Salmonella, Shigella, Campylobacter, diarrheagenic Escherichia coli (EPEC, STEC), Yersinia enterocolitica, Aeromonas species and Clostridioides difficile. Antimicrobial susceptibility was determined by the disk diffusion method for Enterobacterales, Campylobacter and Aeromonas, and by the gradient diffusion method for C. difficile. Of the 26,060 stool samples from patients of any age, 1...

Outbreak caused by pandrug-resistant blaOXA-69/blaOXA-23/blaGES harboring Acinetobacter baumannii ST2 in an intensive care unit
Acta Microbiol Immunol Hung. 2024 Jan 29. doi: 10.1556/030.2024.02202. Online ahead of print.ABSTRACTAcinetobacter baumannii has emerged as a main nosocomial pathogen exhibiting high rates of resistance to clinically relevant antibiotics. Six pandrug-resistant A. baumannii (PDR-A. baumannii) were recovered from three patients in a Tunisian Intensive Care Unit (ICU) between 10th and 16th of May 2018 resulting in one fatal case and raising the possibility of an outbreak. On 18th of May environmental screening of ICU surfaces was carried out. On 22nd of May a fourth patient was infected with PDR-A. baumannii and died. A secon...

Antibiotic resistance and genomic characterization of Mycobacterium abscessus complex isolates from patients with pulmonary tuberculosis in Iran: A multi-center study (2010-2021)
Acta Microbiol Immunol Hung. 2024 Jan 29. doi: 10.1556/030.2024.02169. Online ahead of print.ABSTRACTOne hundred and eighteen sputum specimens suspected of Mycobacterium abscessus infection were collected. Species level identification of M. abscessus was performed by rpoB sequencing. Clonality analysis was done by multilocus sequence typing (MLST) for M. abscessus. Antibiotic susceptibility testing was performed for clarithromycin, amikacin, ciprofloxacin and moxifloxacin. Altogether 128 isolates were obtained and were subjected to rpoB gene sequencing for definite identification. Among them 59 were identified as M. absces...

First detection of a cefiderocol-resistant and extensively drug-resistant Acinetobacter baumannii clinical isolate in Bulgaria
Acta Microbiol Immunol Hung. 2024 Jan 23. doi: 10.1556/030.2024.02201. Online ahead of print.ABSTRACTCefiderocol (CFDC) is a first-in-class siderophore cephalosporin with potent activity against multidrug-resistant Gram-negative bacteria including carbapenem-resistant Acinetobacter baumannii. The present study aimed to explore the CFDC resistance mechanisms of an extensively drug-resistant A. baumannii isolate from Bulgaria. The A. baumannii Aba52 strain (designated Aba52) was obtained in 2018 from a blood sample of a critically ill patient. The methodology included antimicrobial susceptibility testing, whole-genome sequen...

Characterization of disinfectant susceptibility profiles among clinical isolates of Acinetobacter baumannii in Ardabil, Iran
This study evaluated the antimicrobial activity of four commonly used disinfectants; triclosan, chlorhexidine digluconate, benzalkonium chloride, and formaldehyde against Acinetobacter baumannii clinical isolates. This study also determined the prevalence and association of efflux pumps encoding genes qacE, qacED1, emrA, and aceI with tolerance to disinfectants. A total of 100 A. baumannii isolates were included in the current study. The antimicrobial disinfectants' minimum inhibitory concentration (MIC) was determined using an agar dilution method. Genes involved in resistance to disinfectants were investigated by PCR met...

High-risk clonal lineages among extended-spectrum β-lactamase producing Escherichia coli and Klebsiella pneumoniae from urban and rural stagnant water samples in Tunisia
This study sought to investigate the occurrence and subsequently to characterize extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae from urban and rural stagnant water samples during the wet season (December to February) in several regions of northern Tunisia. From 56 stagnant water samples, 14 ESBL-producing Enterobacteriaceae were recovered, including 9 Escherichia coli, 3 Klebsiella pneumoniae, and 2 K. oxytoca. Most isolates were multidrug-resistant, with ESBL production primarily encoded by blaCTX-M-15 (n = 8) and blaCTX-M-1 (n = 4) followed by blaCTX-M-55 (n = 1) and blaTEM-26 (n = 1). One K. pneumo...

Molecular characteristics of carbapenem-resistant Raoultella ornithinolytica
In this study, three CR-ROR strains were found to have a higher level of resistance to antibacterial agents and carried multiple antibiotic resistance genes. The CR-ROR strains carrying multiple antibacterial resistant genes require the stringent monitoring to avoid the spread of multidrug-resistant bacterial strains.PMID:38063919 | DOI:10.1556/030.2023.02123 (Source: Acta Microbiologica et Immunologica Hungarica)
