“…Shigellosis due to S. sonnei is reported to occur at low rates among people living in developing countries. Plesiomonas shigelloides is a gram-negative bacteria often found in surface water that shares antigens with S. sonnei , and until recently P. shigelloides has been a frequently isolated enteric pathogen from <2 years old Bangladeshi children in the diarrhea hospital [15], [16]. It is well accepted that exposure to P shigelloides, through contaminated drinking water, may immunize people to S. sonnei in these developing countries [17].…”

BackgroundShigellosis continues to be a public health challenge for developing countries, including Bangladesh. The aim of the study is to demonstrate recent changes in Shigella sero-groups and their geographical diversity.MethodsData were extracted from data archive of four diarrheal disease surveillance systems. A 2% sub sample from urban Dhaka Hospital (2008–2011; n = 10,650), and 10% from urban Mirpur Treatment Centre (2009–2011; n = 3,585), were enrolled systematically; whereas, all patients coming from the Health and Demographic Surveillance System area in rural Matlab (2008–2011; n = 6,399) and rural Mirzapur (2010–2011; n = 2,812) were included irrespective of age, sex, and disease severity. A fresh stool specimen was collected for identification of Shigella spp. Of them, 315 (3%) were positive for Shigella in Dhaka, 490 (8%) from Matlab, 109 (3%) from Mirpur and 369 (13%) from Mirzapur and considered as analyzable sample size.ResultsAmong all Shigella isolates regardless of age, significant decreases in percentage of S. flexneri over time was observed in Mirpur (55→29%; p value of χ2-for trend = 0.019) and Mirzapur (59→47%; p = 0.025). A non-significant decrease was also seen in Dhaka (58→48%), while in Matlab there was a non-significant increase (73→81%). Similar patterns were observed among under-5 children at all sites. Emergence of S. sonnei was found in Dhaka (8→25%; p<0.001) and Mirpur (10→33%; p = 0.015), whereas it decreased in Mirzapur (32→23%; p = 0.056). The emergence of S. boydii was seen in all ages in Mirzapur [(3→28%; p<0.001); (3→27%; p<0.001)]. On the other hand, we saw non-significant percent reductions in S. boydii in Dhaka [overall (25→16%); under-5 (16→9%)]. Decreasing rates of Shigella dysenteriae were observed in Matlab, Mirpur and Mirzapur; whereas, in Dhaka it remained unchanged.Conclusion and SignificanceEmergence of S. sonnei and S. boydii as important infectious diarrhea etiologies and variations in geographical diversity underscore the need for monitoring, with possible implications for vaccine development.

Practical Guidance for Clinical Microbiology Laboratories: Diagnosis of Bacterial Gastroenteritis

2015

View full text Add to dashboard Cite

SUMMARY Bacterial gastroenteritis is a disease that is pervasive in both the developing and developed worlds. While for the most part bacterial gastroenteritis is self-limiting, identification of an etiological agent by bacterial stool culture is required for the management of patients with severe or prolonged diarrhea, symptoms consistent with invasive disease, or a history that may predict a complicated course of disease. Importantly, characterization of bacterial enteropathogens from stool cultures in clinical laboratories is one of the primary means by which public health officials identify and track outbreaks of bacterial gastroenteritis. This article provides guidance for clinical microbiology laboratories that perform stool cultures. The general characteristics, epidemiology, and clinical manifestations of key bacterial enteropathogens are summarized. Information regarding optimal specimen collection, transport, and processing and current diagnostic tests and testing algorithms is provided. This article is an update of Cumitech 12A (P. H. Gilligan, J. M. Janda, M. A. Karmali, and J. M. Miller, Cumitech 12A, Laboratory diagnosis of bacterial diarrhea, 1992).

“…Interestingly, stools samples as an end product of nutrients metabolism in the content section, several potential aquatic pathogenic bacteria were enriched, including Serratia, Acinetobacter johnsonii, Plesiomonas shigelloides, and Aeromonadaceae (González et al, 2000;Martins et al, 2013;Nadirah et al, 2012;Huang et al, 2018). P. shigelloides is a cause of diarrhea in human, usually isolated from the faeces (Khan et al, 2004) and has also been found from the gut of many fishes, such as tilapia (Oreochromis niloticus) (Nadirah et al, 2012), largemouth bass Micropterus salmoides (Larsen et al, 2014) and Japanese eel Anguilla japonica (Hsu et al, 2018). In grass carps, P. shigelloides has also been found to be associated with muscle erosive disease (Hu et al, 2014).…”

Peer Review #1 of "Systematic evaluation of the gut microbiome of swamp eel (Monopterus albus) by 16S rRNA gene sequencing (v0.2)"

Swamp eel (Monopterus albus) is a commercially important farmed species in China. T he dysbiosis and homeostasis of gut microbiota might be associated with swamp eel's diseases pathogenesis and food digestion. The contribution of gut microbiome in fish growth and health is being increasingly recognized. However, little was known about the microbial community in the intestine of swamp eel (Monopterus albus). Methods The intestinal microbiomes of the five distinct gut sections (midgut content and mucosa, hindgut content and mucosa, and stools) of swamp eel were compared by the Illumina MiSeq sequencing of the bacterial 16S rRNA gene sequencing and statistical analysis. Results The results showed that the number of observed OTUs decreased from proximal to distal of intestine. PCoA analysis revealed significant separations among samples from different gut sections. Nevertheless, there were 54 core OTUs shared by all gut sections and 36 out of 54 core OTUs significantly varied in the abundances in different gut sections. Furthermore, we discovered 66 section-specific enriched KEGG pathways. These section-specific enriched microbial taxa (e.g., Bacillus, Lactobacillus) and potential function capacities (e.g., amino acid metabolism, carbohydrate metabolism) might play vital roles in nutrients metabolism, immune modulation, and host-microbe interactions of swamp eel. Conclusions Our results showed that the microbial diversity, composition, and function capacity were varied substantially in different gut sections. The gut section-specific enriched core microbial taxa and function capacities may exert an important role in swamp eel's nutrients metabolism, immune modulation, and host-microbe interactions. This study should provide basic insights into the gut microbiome of swamp eel.
