J Microbiol 2018 Oct 2. Epub 2018 Oct 2.

Radiation Biotechnology Division, Korea Atomic Energy Research Institute, Jeongeup, 56212, Republic of Korea.

Salmonella enterica is a major human pathogen that causes invasive non-typhoidal Salmonellosis (iNTS), resulting in significant morbidity and mortality. Although a number of pre-clinical and clinical studies have reported on the feasibility of developing a safe and effective vaccine against iNTS, there have been no licensed Salmonella vaccines available to protect against NTS strains. Vaccine formulations of highest priority for NTS are live attenuated vaccines, which can elicit effective induction of intestinal mucosal and intracellular bacteria-specific cell mediated immune responses.

Prevalence of Salmonella in juvenile dogs affected with parvoviral enteritis.

J S Afr Vet Assoc 2018 Dec 5;89(0):e1-e6. Epub 2018 Dec 5.

Department of Companion Animal Clinical Studies, University of Pretoria.

Salmonellosis is a disease of major zoonotic importance and canine parvovirus is a potentially fatal cause of canine enteritis with a world-wide distribution. Persistent isolation of Salmonella during routine environmental sampling surveys of a hospital ward, reserved for the treatment of dogs with canine parvovirus infection, prompted investigation into a possible source. We hypothesised that dogs affected by canine parvovirus would have a higher prevalence of faecal salmonellae compared to an apparently healthy cohort. Read More

Department of Horticulture, University of Georgia, 2360 Rainwater Rd., Tifton, GA 31793-5766, USA.

Plant genotype has been advocated to have an important role in the fate of enteric pathogens residing in lettuce foliage. This study was therefore undertaken under the premise that different pathogen responses could occur in lettuce cultivars with cultivar selection being one of several hurdles in an overall strategy for controlling foodborne pathogens on field-grown produce. Up to eight lettuce cultivars ('Gabriella', 'Green Star', 'Muir', 'New Red Fire', 'Coastal Star', 'Starfighter', 'Tropicana', and 'Two Star') were examined in these experiments in which the plants were subjected to spray contamination of their foliage with pathogens.

Evaluation of temocillin for phenotypic carbapenemase screening of Escherichia coli and Salmonella enterica isolates in relation to the presence of genes encoding ESBLs and carbapenemase production.

J Antimicrob Chemother 2018 Dec 13. Epub 2018 Dec 13.

Statens Serum Institut, Copenhagen, Denmark.

Background: The expression of enzymes of the OXA-48 carbapenemase group is difficult to detect by phenotypic methods owing to frequent low levels of carbapenem resistance and negative results with some screening methods. Temocillin has been shown to be a good option for phenotypic screening as it is hydrolysed by the OXA-48-group enzymes, whereas ESBLs, AmpC and some other carbapenemases have a lower hydrolytic effect on this antimicrobial. However, no epidemiological cut-off for temocillin is available. Read More

Overexpression of Toll-like receptor 4 enhances LPS-induced inflammatory response and inhibits Salmonella Typhimurium growth in ovine macrophages.

Eur J Cell Biol 2018 Nov 29. Epub 2018 Nov 29.

Beijing Key Laboratory for Animal Genetic Improvement, College of Animal Science and Technology, China Agricultural University, Beijing, China; National Engineering Laboratory for Animal Breeding, College of Animal Science and Technology, China Agricultural University, Beijing, China. Electronic address:

The Toll-like receptor 4 (TLR4) plays a crucial role in innate inflammatory responses, as it recognizes gram-negative bacteria (or their products) and contributes greatly to host defense against invading pathogens. Though TLR4 overexpressing transgenic sheep, resistant to certain diseases related with gram-negative bacteria, had been bred in our previous research, the effects of overexpression of TLR4 on innate immune response remained unclear. In this study, TLR4 overexpressing ovine macrophages were obtained from peripheral blood, and it was found that the overexpression of TLR4 initially promoted the production of proinflammatory cytokines TNFα and IL-6 by activating TLR4-mediated IRAK4-dependent NF-κB and MAPK (JNK and ERK1/2) signaling following LPS stimulation.

What role does pyroptosis play in microbial infection?

J Cell Physiol 2018 Dec 7. Epub 2018 Dec 7.

College of Animal Science and Veterinary Medicine, Henan Institute of Science and Technology, Xinxiang, China.

Pyroptosis, a type of programmed cell death mediated by gasdermin, is characterized by the swelling and rupture of cells, release of cellular contents and a strong inflammatory response, which is critical for controlling microbial infection. Pattern recognition receptors recognize the intracellular and extracellular pathogenic microbial components and stimulate the organism's inflammatory response by activating the pyroptosis signaling pathway and releasing interleukin-1β (IL-1β), IL-18, and other inflammatory factors to promote pathogen clearance and prevent infection. In the process of continuous evolution, pathogens have developed multiple strategies to modulate the occurrence of pyroptosis and thus enhance their ability to induce disease; that is, the competition between host cells and pathogens controls the occurrence of pyroptosis.
