Accurate and rapid typing of pathogens is essential for effective surveillance and outbreak detection. Conventional serotyping of Escherichia coli is a delicate, laborious, time-consuming, and expensive procedure. With whole-genome sequencing (WGS) becoming cheaper, it has vast potential in routine typing and surveillance. The aim of this study was to establish a valid and publicly available to...

Classical antibody-based serotyping of Escherichia coli is an important method in diagnostic microbiology for epidemiological purposes, as well as for a rough virulence assessment. However, serotyping is so tedious that its use is restricted to a few reference laboratories. To improve this situation we developed and validated a genetic approach for serotyping based on the microarray technology....

Campylobacter jejuni remains a major cause of bacterial diarrhea worldwide and is associated with numerous sequelae, including Guillain Barré Syndrome, inflammatory bowel disease, reactive arthritis, and irritable bowel syndrome. C. jejuni is unusual for an intestinal pathogen in its ability to coat its surface with a polysaccharide capsule (CPS). These capsular polysaccharides vary in sugar co...

Swine dysentery is a mucohemorrhagic diarrheal disease caused by the anaerobic spirochete Serpulina hyodysenteriae. At present, the serotyping is done by immunodiffusion testing with lipopolysaccharide (LPS) extract as antigen and rabbit hyperimmune sera produced against different serotypes of S. hyodysenteriae. Since the preparation of LPS is time-consuming and requires a large quantity of bac...

PURPOSE This study was carried out to analyze the epidemiology of gonorrhea based on antimicrobial susceptibility testing, auxotyping and serotyping in New Delhi, India. METHODS Sixty gonococcal isolates from males with urethritis, females with endocervicitis and their sexual contacts were studied. The isolates were subjected to antimicrobial susceptibility testing, auxotyping and serotyping ...

Human enteroviruses have traditionally been typed according to neutralization serotype. This procedure is limited by the difficulty in culturing some enteroviruses, the availability of antisera for serotyping, and the cost and technical complexity of serotyping procedures. Furthermore, the impact of information derived from enterovirus serotyping is generally perceived to be low. Enteroviruses ...

aims: cholera is an acute diarrheal disease that can lead to severe dehydration and death. antibiotic resistance is a big challenge in infective disease like cholera. the present study aimed to understand the characteristics and trends of antibiotic resistance of v. cholerae isolations in and around kashan, iran. instrument & methods: in this descriptive cross-sectional study, samples were gath...

The present study carried out to evaluate the presence of diarrheagenic Escherichia as causes of diarrhea in young calves in Damietta governorate during period from November 2015 to March 2016. Bacteriological examination was done on a total of (100) fecal samples collected from young diarrhoeic calves of average age of 2 to 21 days to detect the prevalence of E. coli . The samples were grouped...
