International trade, new agricultural, animal production and food practices have facilitated the spread and transmission of food-borne pathogens; including Salmonella. Salmonella is a ubiquitous bacterium responsible for a variety of diseases in humans, animals. It has a large diversity and contains more than 2579 serotypes. However, very little work describing the diversity, structure and populations dynamics of Salmonella in different hosts is available in Niger. In order to describe the general context of Salmonella diversity in Africa, an analysis of the available literature on this subject was carried out. A total of 131 publications were identified. From those publications, twenty five (25) were eligible. The LOGIT estimation model was used for serotype analysis to standardize the distribution of data and minimize sample sizes. It appears from our analysis that the prevalence of Salmonella is high regardless of the host and host germ. The major serotypes found in humans in Africa are S. Typhimurium, S. Enteritidis and S. Typhi. In poultry, the predominant serotype is S. Hadar on the other side S. Typhimurium predominates in North Africa. Thus, the results of these review analyzes constitute one of the steps in the process of understanding trends in the distribution of Salmonella in Africa. These results are presented as an outline of the implementation of a successful

“…Most of the reported cases of S. Stanleyville and S. Senftenberg isolation in humans occurred in Africa, so these seem to be endemic in Africa. S. Stanleyville and S. Senftenberg have been previously isolated in other West African countries [13,14]; however, they have never been reported in Ghana. There are few reports of the isolation of Salmonella in Ghana, probably due to the lack of facilities and logistics in the region for performing these tests.…”

Introduction: Salmonella infections are increasing worldwide, but there are few reports on Salmonella surveillance in African countries and other developing countries. This has made it difficult to estimate the actual burden of salmonellosis, especially in Africa. This study was conducted in a neglected Northern Region of Ghana where there are no previous data on Salmonella serotypes. Methodology: Standard microbiological tests were used for isolation, identification, and serotyping. Micro-dilution was used for the antimicrobial susceptibility tests. Results: Four serotypes of Salmonella were identified: S. Urbana, S. Ouakam, S. Senftenberg, and S. Stanleyville. All the serotypes were susceptible to the 20 antibiotics used in the susceptibility test. S. Urbana and S. Ouakam were identified in humans for the first time in Africa. Conclusion: This study may serve as a baseline study for future investigations on Salmonella in the region and may assist public health officials to take the appropriate measures in case of a disease outbreak caused by Salmonella in the area. The article may also give health officials a fair idea of the resistance level of these serotypes in the region.

“…Many approaches, such as subtractive hybridization, next generation sequencing, and microarray techniques, have been used to identify genes that are specific or unique to a pathogen [17]. A nested polymerase chain reaction using H1-d primers has been used to amplify specific genes of S. typhi in the blood of patients and is a promising means of making a rapid diagnosis [149].…”

Salmonella typhi is the causal organism for the typhoid fever. Typhoid disease is a problem in those developing countries where lack of sanitation, poor water supplies and exposure to unhygienic and polluted environment is a part of routine life of majority of population. Salmonella typhi expresses various virulence antigens like H-antigens, O-antigens and Vi antigens which plays vital role in the infection and pathogenesis of the bacteria. Salmonella typhi causes fever, nausea, headache, body fatigue and bowel related complications in the patients. This disease had been diagnosed by culture method, Widal test for past several decades. These diagnostic techniques are being replaced by the modern assays like ELISA, Dot blot ELISA, DipStick Assays, RT-PCR and other molecular assays. The evolution in diagnostic assays had occurred as the antibiotic resistance in the Salmonella typhi had shown an increase. The Salmonella typhi had been evolved into a multidrug resistant bacteria which need to be timely diagnosed to start the appropriate and correct treatment of typhoid to prevent further complications. This article imparts a brief glimpse on Salmonella typhi, typhoid fever and diagnostic assays available at clinical laboratories. There is a need to focus on the correct and rapid diagnostic methods which should be modified and made accessible to the clinical diagnostic laboratories.
