A 23-year retrospective investigation of Salmonella Typhi and Salmonella Paratyphi isolated in a tertiary Kathmandu hospital. [PDF]

PLoS Neglected Tropical Diseases, 2017
Salmonella serovars Typhi (S. Typhi) and Paratyphi A (S. Paratyphi A), the causative agents of enteric fever, have been routinely isolated organisms from the blood of febrile patients in the Kathmandu Valley since the early 1990s.

Phylogenetic analysis reveals an ancient gene duplication as the origin of the MdtABC efflux pump. [PDF]

, 2020
The efflux pumps from the Resistance-Nodulation-Division family, RND, are main contributors to intrinsic antibiotic resistance in Gram-negative bacteria. Among this family, the MdtABC pump is unusual by having two inner membrane components.

Characterization of the Salmonella paratyphi C Vi polysaccharide [PDF]

Infection and Immunity, 1989
The Vi capsular polysaccharide (Vi) is both a virulence factor and a protective antigen of Salmonella typhi; its pathogenic role for Salmonella paratyphi C is less well understood. We found no differences between the antigenic and immunogenic properties and the structure of the Vi from representative strains of S. paratyphi C, S. typhi, and Citrobacter

Neutral genomic microevolution of a recently emerged pathogen, salmonella enterica serovar agona [PDF]

, 2013
Salmonella enterica serovar Agona has caused multiple food-borne outbreaks of gastroenteritis since it was first isolated in 1952. We analyzed the genomes of 73 isolates from global sources, comparing five distinct outbreaks with sporadic infections as

Resistance to carbapenems in non-typhoidal Salmonella enterica serovars from humans, animals and food [PDF]

, 2018
Non-typhoidal serovars of Salmonella enterica (NTS) are a leading cause of food-borne disease in animals and humans worldwide. Like other zoonotic bacteria, NTS have the potential to act as reservoirs and vehicles for the transmission of antimicrobial ...

Incidence of diarrhea caused by rotavirus infections in rural Zhengding, China: prospective, population-based surveillance.

, 2005
Rotavirus is the pathogen most commonly associated with severe gastroenteritis in young children in the People's Republic of China, yet there are few population-based data on the incidence of rotavirus infection. The present study investigated the burden

Loss of very-long O-antigen chains optimizes capsule-mediated immune evasion by Salmonella enterica serovar Typhi. [PDF]

, 2013
UnlabelledExpression of capsular polysaccharides is a variable trait often associated with more-virulent forms of a bacterial species. For example, typhoid fever is caused by the capsulated Salmonella enterica serovar Typhi, while nontyphoidal Salmonella

Types of Salmonella paratyphi B and their phylogenetic significance [PDF]

Journal of Medical Microbiology, 1988
The substrates inositol, rhamnose, d-tartrate and m-tartrate used in fermentation tests with 338 cultures of Salmonella paratyphi B differentiated strains in some phage types to give information that could be used in epidemiological investigations. Xylose in Bitter's medium, the fifth substrate by which 13 of a potential 32 biotypes were identified ...
