ShigaShield™ is a phage preparation composed of five lytic bacteriophages that specifically target pathogenic Shigella species found in contaminated waters and foods. In this study, we examined the efficacy of various doses (9x105-9x107 PFU/g) of ShigaShield™ in removing experimentally added Shigella on deli meat, smoked salmon, pre-cooked chicken, lettuce, melon and yogurt. The highest dose (2...

| Shigellosis caused by multidrug-resistant (MDR) Shigella strains is an important cause of morbidity and mortality in developing countries. Shigella strains usually harbour heterogeneous population of plasmids which can confer resistance to different antibiotics. A hospital based survey was conducted to determine the pattern of antimicrobial resistance and plasmid profiles in Shigella species ...

Examination of faecal specimens for the presence of Yersinia spp. during a 1-year period yielded isolations from 3.5% of patients. Salmonella spp., Campylobacter spp. and Shigella spp. were isolated from 2.5%, 2.8% and 0.34% of patients respectively. Most isolates belonged to Y. enterocolitica biotype 1 (53%) and Y. frederikseni (39%). The most frequently encountered serotypable strains were se...

Diarrhoeal diseases and enteric infections are major causes of morbidity and mortality in the developing countries. Shigellosis was sixth in the rank of death caused by infectious disease in China. Present study assess the patterns of antimicrobial susceptibility and mutations in marA genes of Shigella isolates and its association. One hundred isolates of Shigella spp were tested to evaluate th...

A rapid seminested polymerase chain reaction (PCR) method for the specific, sensitive detection of virulent Shigella spp. in spiked environmental water samples was developed. A set of primers specific for the invasion plasmid antigen gene (ipaH) of virulent Shigella spp. and enteroinvasive Escherichia coli produced a 620-bp fragment that was used as template for the seminested primer pair delin...

In this study, we used plasmid profile analysis, XbaI macrorestriction with pulsed-field gel electrophoresis (PFGE), and PCR of the ipaH gene, to study the molecular characteristics of 183 Shigella spp. isolated during May 2000 to April 2003 from rectal swabs of patients with watery and/or bloody diarrhoea in a new industrialized area of Thailand. Among the 183 isolates, 167 were S. sonnei and ...

An epidemic of bacillary dysentery caused by multiply resistant Shigella dysenteriae type 1 swept through all the districts of West Bengal in 1984 (S. C. Pal, Letter, Lancet i:1462, 1984), providing us the opportunity to evaluate the efficacy of two drugs in the treatment of invasive diarrhea, particularly shigellosis. Male patients over 5 years of age admitted to the Infectious Diseases Hospit...

The growth and appearance of 115 stock Salmonella isolates on a new formulation of CHROMagar Salmonella (CAS) medium were compared to those on xylose-lysine-desoxycholate agar (XLD), Salmonella-Shigella agar (SS), and Hektoen enteric agar (HEA) media. CAS medium was then compared prospectively to XLD and SS for the detection and presumptive identification of Salmonella strains in 500 consecutiv...

Acute diarrheal disease (ADD) can be caused by a range of pathogens, including bacteria, viruses, and parasites. Conventional diagnostic methods, such as culture, microscopy, biochemical assays, and enzyme-linked immunosorbent assays (ELISA), are laborious and time-consuming and lack sensitivity. Combined, the array of tests performed on a single specimen can increase the turnaround time (TAT) ...

Escherichia spp., including E. albertii and E. coli, Shigella dysenteriae, and S. flexneri are causative agents of foodborne disease. We report here reference-level whole-genome sequences of E. albertii (2014C-4356), E. coli (2011C-4315 and 2012C-4431), S. dysenteriae (BU53M1), and S. flexneri (94-3007 and 71-2783).
