A series of bacteriophages specific for Escherichia coli (E-1, E-2, E-3, and E-4), Citrobacter freundii (phi I, phi II, and phi III), Enterobacter cloacae (Ent), and Shigella spp. (Sh) have been isolated from hospital sewage. These bacteriophages, in combination with Felix Salmonella phage O-I, were used as a diagnostic phage typing set which included seven phage preparations: O-I, C (phi I and...

Strains of enteropathogenic Escherichia coli (EPEC) generally employ the adhesins bundle-forming pili (Bfp) and intimin to colonize the intestine. Atypical EPEC strains possess intimin but are negative for Bfp and, yet, are able to cause disease. To identify alternative adhesins to Bfp in atypical EPEC, we constructed a transposon mutant library of atypical EPEC strain E128012 (serotype O114:H2...

Diarrheal diseases are the second highest cause of mortality of children under 5 years worldwide. There is a continuous search for developing a cost-effective treatment for diarrhea as the present ones are facing challenges. Medicinal plants can be explored further as an alternative treatment for diarrhea. Psidium guajava leaves have been used as an antidiarrheal globally. Citrobacter rodentium...

background and objectives: leucine dehydrogenase (leudh; ec 1.4.1.9) belongs to the amino acid dehydrogenase family and isused as a biocatalyst in medical and pharmaceutical industries (1). this study reported deals with the isolation and characterization of leudh from a thermophilic bacterium isolated from jask port in the province of hormozgan. materials and methods: aliquots of soil and wate...

Paraspinal abscess and spondylodiscitis due to Citrobacter koseri is a very rare condition. We report a remarkable case of Citrobacter koseri bacteraemia complicated by paraspinal abscess and spondylodiscitis in a patient who has successfully been treated in our hospital. Our patient demonstrates one of the common challenges in the practice of infectious disease medicine, wherein an innocuous p...

Citrobacter koseri, Plesiomonas shigelloides, Edwardsiella tarda, Yersinia enterocolitica, Alkalescens dispar, Vibrio parahaemolyticus, and Vibrio alginolyticus were seven interesting microorganisms isolated recently in our diagnostic laboratory.

Sir, Temocillin, a semi-synthetic 6-a-methoxy derivative of ticarcillin, has been shown to be clinically efficacious in infections caused by extended-spectrum b-lactamase (ESBL)and AmpC-producing Enterobacteriaceae. It is licensed in the UK for bacteraemia, urinary tract infections (UTIs) and lower respiratory tract infections where susceptible Gram-negative bacteria are suspected or confirmed....
