a hundred and five strains of salmonella havana were studied from the patients of pediatric hospital of tehran and tabriz during 1976-86. the sources of the strains in order to their frequency were from-stool, blood, spinal, fluid, wound and urine. from the epidemiological point of view salmonella havana is serotype of most non-typhoid salmonella. all of the strains had drug resistancy and most...

Introduction: Calf diarrhea is one of the significant problems in dairy farms associated with treatment costs and reduced livestock production. Salmonellae are among the most common and the major causative agents of diarrhea in calves and humans. The present study was carried out to isolate and identify Salmonella in fecal samples of calves in industrial dairy farms of Hamedan and to determine ...

To determine antimicrobial drug resistance of Streptococcus pneumoniae serotypes, we analyzed isolates from blood cultures of sick children residing in the West Bank before initiation of pneumococcal vaccination. Of 120 serotypes isolated, 50.8%, 73.3%, and 80.8% of the bacteremia cases could have been prevented by pneumococcal conjugate vaccines. Serotype 14 was the most drug-resistant serotyp...

Abstract In this study, we focused on the emergence of extensively drug-resistant (XDR), pandrug-resistant (PDR), and hypervirulent Klebsiella pneumoniae (hvKP) in Iran. During 2018 to 2020 a total 52 K. isolates were collected from different clinical specimens. The hvKP identified by PCR amplification virulence capsular serotype-specific genes. Hypermucoviscous (hmKP) string test. Carbapenem-r...

background and objectives: group b streptococci (gbs) is a major cause of neonatal and maternal infections. the aim of this study was to determine the serotype distribution and antibiotic resistance profile of gbs strains isolated from pregnant women in ardabil. materials and methods: antibiotic resistance of 56 gbs isolates was investigated using e-test strips and disk-diffusion method. seroty...

Salmonella is a major cause of food poisoning, and its infection antimicrobial resistance vary regionally due to different sanitary standards the use antimicrobials. The aim this study evaluate microbiological contamination in Shanghai, providing references for supervision over safety clinical treatment. This analysed distribution serotypes, poultry meats serotype Salmonella, correlation betwee...

We investigated the serotypes, distributions, and antimicrobial resistance of Campylobacter jejuni isolates from humans and animals as a source of infection in poultry between 2002 and 2003. A total of 50 C. jejuni isolates from humans and 29 C. jejuni isolates from poultry were studied for serotype using the Penner serotyping scheme and the drug susceptibilities of the isolates which were dete...

To determine antimicrobial drug resistance patterns, we characterized nontyphoidal Salmonella enterica strains isolated in Liverpool, UK, January 2003 through December 2009. Decreased susceptibility to ciprofloxacin was found in 103 (20.9%) of 492 isolates. The lower susceptibility was associated with ciprofloxacin treatment failures and with particular serovars and phage types often acquired d...

We report a cluster of pediatric diarrhea due to Shigella dysenteriae serotype 1 involving 11 children in France, including the index case, who had returned from Senegal. Child-to-child transmission was documented by ribotyping. Five children developed hemolytic uremic syndrome (HUS). On the basis of our findings, the choice of antimicrobial treatment for infections with S. dysenteriae serotype...
