Genetic diversity of healthcare-associated methicillin-resistant Staphylococcus aureus isolates from Southern Iran
This study aimed to investigate the molecular epidemiology as well as the antibiotic resistance pattern of clinical isolates of MRSA from Southern Iran. A total of 135 S. aureus isolates were collected from the patients referred to three hospitals in South Iran. The phenotypic and genotypic diagnosis of MRSA isolates was performed by disk diffusion and PCR methods, respectively. The antibiotic resistance pattern for MRSA isolates was performed using Kirby-Bauer method. The molecular epidemiology of isolates was performed by MLST, Spa typing and SCCmec typing. From 135 S. aureus isolates, 50 (37%) MRSA strains were detected...

Discrepancy between colistin and polymyxin B susceptibility results among Escherichia coli and Klebsiella pneumoniae clinical isolates
This study aimed to determine the correlation between the MIC values of polymyxin B and colistin. A total of 505 isolates, including 122 isolates of Escherichia coli and 383 isolates of Klebsiella pneumoniae were included in the present study. All the isolates were assessed for colistin and polymyxin B using the broth microdilution method. The categorical agreement in the E. coli isolates was 98.4%, and the rate of very major error was 33.3%. The categorical agreement in the K. pneumoniae isolates was 99.5%, the rate of major error was 0.36%, and the rate of very major error was 0.98%. In the evaluation of the essential ag...

Discrepancy between colistin and polymyxin B susceptibility results among Escherichia coli and Klebsiella pneumoniae clinical isolates
This study aimed to determine the correlation between the MIC values of polymyxin B and colistin. A total of 505 isolates, including 122 isolates of Escherichia coli and 383 isolates of Klebsiella pneumoniae were included in the present study. All the isolates were assessed for colistin and polymyxin B using the broth microdilution method. The categorical agreement in the E. coli isolates was 98.4%, and the rate of very major error was 33.3%. The categorical agreement in the K. pneumoniae isolates was 99.5%, the rate of major error was 0.36%, and the rate of very major error was 0.98%. In the evaluation of the essential ag...

Online ahead of print.ABSTRACTThe purpose of our study was to investigate the epidemiology of coagulase negative staphylococci (CoNS) responsible for bacteremia in hematopoietic stem cell transplant (HSCT) recipients and to determine the prevalence and the genetic background of methicillin resistance. The prevalence of CoNS bacteremia was 7.4% (54/728), higher in allograft (10.7%) than in autograft (4.7%) recipients. A sepsis or a septic shock were observed in 9% of cases.

A fatal rabies case and experiences of a mass post exposure prophylaxis among healthcare workers
In this study 109 HCWs and eight household contacts were PEP candidates. Contact persons without infection control precautions were in Group I (high risk-82 cases). HCWs indirectly exposed to environmental surfaces were classified in Group II (low risk-35 cases). PEP schedule was rabies vaccine (RBV) + equine rabies immunoglobulin (eRIG) in Group I and only RBV in Group II. Local and systemic AE were observed in all cases. Efficacy of post exposure prophylaxis (PEP) was determined by rabies development in a six month follow-up. 585 doses of RBV have been used in 117 cases and eRIG has been used in 82 cases. 32 Nurses (39%)...

Molecular characterization of ESBL- producing uropathogenic Escherichia coli recovered from urine samples of patients attending a University Teaching hospital in Nigeria
This study aimed to detect extended spectrum beta-lactamase (ESBL) genes and antibiotic resistance profile of uropathogenic Escherichia coli (E. coli) recovered from patients attending a University Teaching hospital in Nigeria. Uropathogenic E. coli isolates were obtained from the culture collection of Department of Microbiology and Parasitology of the University Teaching hospital for a period of four months (October 2019-January, 2020). Antibiotic susceptibility testing was done using the disc diffusion method while phenotypic ESBL production was detected using double disc synergy test (DDST). Detection of β-lactamas...
