Published: December 1994

A slot blot enzyme-linked immunosorbent assay, using monoclonal antibodies specific only for Salmonella paratyphi A, to detect S. paratyphi A contamination in raw prawns has been established. When artificially contaminated prawn samples were tested. S. paratyphi A contamination could be identified correctly within 20 h. No false positives from samples artificially contaminated by other microorganisms were obtained. The sensitivity was such that as few as 1 S. paratyphi A organism per g of raw prawn could be detected. Therefore, the assay constituted a promising test for the rapid and specific detection of S. paratyphi A in prawns.

In this work, microalgae-based zinc oxide nanoparticles loaded with electrospun polyvinyl alcohol (PVA)/sodium alginate (SA) nanofibers were fabricated by electro-spinner. PVA/SA fibrous mats were crosslinked by citric acid, which enhanced their thermal stability and swelling behavior. Green-synthesized ZnO NPs were laboratory synthesized and characterized by FTIR, XRD, EDX, SEM, TEM and TGA analyses.

S. enterica isolates (n = 78) obtained from the vegetable supply chain (farms, distribution centers, markets) in two Cambodian provinces (Siem Reap, Battambang) were sequenced and analyzed. In silico identification of serotypes and detection of antimicrobial resistance genes was performed using SISTR and ABRicate, respectively.

Background: Enteric fever caused by Salmonella enterica serovars Typhi and Paratyphi A in addition to gastroenteritis and invasive disease, predominantly attributable to nontyphoidal Salmonella serovars Typhimurium and Enteritidis, are major causes of death and disability across the globe. A broad-spectrum vaccine that protects against disease caused by typhoidal and nontyphoidal serovars of Salmonella is not available for humans but would prevent a considerable burden of disease worldwide.

Methods: We previously developed a broad-spectrum vaccine for Gram-negative bacteria that is based on the inner core domain of detoxified Escherichia coli O111, Rc (J5) mutant lipooligosaccharide, a highly conserved antigen across Gram-negative bacteria, complexed with an outer membrane protein of group B Neisseria meningitidis.

Unlabelled: The ability to treat infections is threatened by the rapid emergence of antibiotic resistance among pathogenic microbes. Therefore, new antimicrobials are needed. Here we evaluate mannitol-1-phosphate 5-dehydrogenase (MtlD) as a potential new drug target.
