“…Poor hygiene practices; such as inadequate washing of hands, fruits and vegetables, contaminated food and water, and contaminated animal products, are all responsible for the transmission of Salmonellosis [1,3,4]. Also, with the rapid emergence of antimicrobial resistance strains of Salmonella species [17], it is of utmost importance that healthy individuals do not take routine antimicrobial medications in mild to moderate cases; safe in geriatrics, infants or children below five years of age, and immune-compromised individuals [1].…”

It is vital to study and understand the genetic basis to the virulence of different Salmonella strains in other to fully grasp the facts behind the unique capabilities of these pathogenic agents to causing diseases in both humans and animals. In this study, the conventional microbiological culture methods were used to isolate pure Salmonella strains from 120 vegetable samples of five different types; which were all obtained at seven different popular markets in the Jos Metropolis of North-Central Nigeria. 25 (20.8%) pure isolates were obtained from 120 samples after initial culture and sub-cultures; with 24 (20%) of the pure isolates testing positive as being pathogenic after biochemical analysis. From the 25 pure isolates, the same 24 which tested positive for biochemical tests were also successfully amplified by PCR technique with the Salmonella invA virulence gene. The result shows that 96% of the pure isolates were positive for the Salmonella invA gene. The PCR product which was very specific is a 250bp fragment of DNA which was visualized in 1.5% agarose gel. This finding shows that virulent Salmonella strains pose a major health hazard and public health concern to the affected population. Our study shows that there is a high prevalence rate of virulent Salmonella strains in North-Central Nigeria. It is thus concluded that although both the conventional culture and biochemical methods of isolating Salmonella species are most useful for obtaining pure isolates and identifying pathogenic strains, however, the PCR technique remains the most specific and sensitive; especially when the rapid identification and detection of virulent strains of Salmonella species are of utmost importance.

“…These results may suggest that sediments of the Apies River harboured more diversity than the water. All these pathogenic bacteria are linked to gastro-intestinal infections worldwide (Weinberger and Keller, 2005) and are reported to be multidrug resistant (Gordon et al, 2008). The Salmonella enterica isolated exhibited a 99% genetic relatedness which may suggest a common ancestry and origin between isolates from river water and riverbed sediment, as suggested by Grant et al (2001) (2015) on genetic relatedness between commensal and pathogenic strains of E. coli from lettuce and irrigation water using the phylogenetic tree, they found high genetic relatedness despite the sites being 246 km apart.…”

Riverbed sediment is a vital component of river ecosystems and plays an important role in many geomorphological and ecological processes. However, when re-suspension occurs, pathogenic bacteria associated with sediment particles may be released into the water column, thus creating a health risk to those who use such water for drinking, household and recreational purposes. The aim of this study was to investigate the presence of bacterial pathogens Salmonella spp. and Shigella spp. in the Apies River and to ascertain whether there was any level of genetic relatedness between river water and riverbed sediment isolates of these pathogenic bacteria. A total of 124 water and sediment samples were collected from a site located on the Apies Rivers upstream of the Daspoort Wastewater Treatment Works, Pretoria, Gauteng, South Africa, between August and November 2014. In order to detect and identify the target bacteria, samples were analysed by culture-dependent and culture-independent techniques (quantitative real-time PCR). Genetic relatedness was established using Sanger sequencing of the invA gene of Salmonella spp. and ipaH of Shigella spp. Results of this study displayed the presence of the target bacteria both in the water and sediment of the river. The phylogenetic tree of Salmonella spp. revealed a ≥ 99% and 99% genetic relatedness between river water and riverbed sediment isolates for Salmonella spp. and Shigella spp., respectively. The degree of genetic relatedness between sediment and water pathogen isolates suggests that these organisms could possibly have a common origin and that there could be possible movement of microorganisms between the water column and the sediments.

Recent trends in the epidemiology of non-typhoid Salmonella and antimicrobial resistance: the Israeli experience and worldwide review

Abstract: Many important trends of non-typhoid Salmonella epidemiology are not restricted to a single geographic location, but spread worldwide, reflecting the global nature of the epidemic. This epidemic imposes a heavy burden worldwide.
