Isolation and characterization of enteroaggregative,enterotoxigenic, diffusely adherent <Emphasis Type="Italic">Escherichia coli</Emphasis> and <Emphasis Type="Italic">Salmonella</Emphasis> Worthington from human diarrhoeic faecal samples in Kashmir and Secunderabad,India

Seven hundred and thirty-five diarrhoeic faecal samples from children were investigated for presence of enteroaggregative E. coli (EAEC), enterotoxigenic E. coli (ETEC), diffusely adherent E. coli (DAEC) and Salmonella spp. by polymerase chain reaction (PCR) and bacterial culture. Out of 675 samples from Kashmir, 55 isolates were obtained, which carried at least one virulence gene studied. Out of the 55 isolates, 36 (65.45%) were EAEC, 18 (32.72%) were ETEC while only one isolate (1.81%) was DAEC. All the EAEC isolates were found to be typical as they possessed aggR gene. Six (16.66%) EAEC isolates carried the astA gene. Out of the 18 ETEC isolates, 13 carried the elt gene alone, four possessed both the elt and est genes and the remaining one harboured the est gene alone. Five ETEC isolates also possessed astA gene. Nineteen EAEC isolates belonged to 10 different serogroups. Serogroup O153 was most frequent. The ETEC isolates also belonged to 10 different serogroups of which O159 was most predominant. Out of 224 E. coli isolates from 60 samples of Secunderabad, 27 isolates carried at least one virulence gene. Out of 27 isolates 22 (81.48%) were typical EAEC, three (11.11%) were ETEC and two (7.4%) were DAEC. Fifteen EAEC isolates belonged to seven different serogroups with O86 as most frequent. Four EAEC isolates also possessed the astA gene. All the three ETEC isolates harboured elt gene only and belonged to three different serogroups. Two isolates of Salmonella Worthington were obtained from only two samples in Kashmir.

The Role of Probiotics in the Treatment of Dysentery: a Randomized Double-Blind Clinical Trial

Diarrhea is considered as an important cause of morbidity and mortality, even though one of the main reasons of death following diarrhea is initiated by dysentery. In recent years, the consumption of probiotics has been proposed for the treatment of infectious diarrhea. Despite most of the studies on probiotics have focused on acute watery diarrhea, few studies in the field of dysentery have found beneficial effects of probiotics. This study is a randomized double-blind clinical trial. The patients were randomly placed into control and case groups. In the intervention group, the patients received probiotics in the form of Kidilact® sachet, which contained high amounts of 7-strain friendly bacteria strains of Lactobacillus casei, Lactobacillus acidophilus, Lactobacillus rhamnosus, Lactobacillus bulgaricus, Bifidobacterium infantis, Bifidobacterium breve, and Streptococcus thermophiles. On the other hand, the patients in the control group received placebo sachets on a daily basis for 5 days. It is notable that the treatment protocol of acute dysentery was done on both groups. The results of this study showed significant differences in the duration of blood in diarrhea between probiotic consumers (2.62 days) and the control group (3.16 days) (P value = 0.05). Additionally, significant differences in the average length of hospitalization in probiotic consumers (3.16 days) and control (3.66 days), (P value = 0.02) could be claimed that the consumption of probiotics is effective in reducing the duration of dysentery and diarrhea. The results of this study suggest that the use of probiotics can be effective in reducing the duration of blood in diarrhea. This study was also recorded in the Iran center of clinical trials registration database (IRCT2014060617985N1).
