Temporal trends in bulk milk antibodies to Salmonella, Neospora caninum, and Leptospira interrogans serovar hardjo in Irish dairy herds [PDF]

, 2012
peer-reviewedBulk milk samples were collected from 309 Irish dairy herds at four time points during 2009 and tested for antibodies to Salmonella spp., N. caninum, and L. hardjo, three abortifacient agents in Irish dairy herds. Of the 312 study herds, 49%

Cytosolic delivery of bacterial metabolites by riboflavin transporters promotes MR1 antigen presentation and MAIT cell recognition

Immunology &Cell Biology, EarlyView.
VitBAg antigen presentation is promoted through a cytosolic pathway that reaches ligand‐receptive MR1 to present to MAIT cells, like the riboflavin transport pathway. Riboflavin solute carrier transporters can promote this MR1 presentation, but they are not essential for this role, suggesting redundant pathways to uptake VitBAg.

A Novel Loop-Mediated Isothermal Amplification (LAMP) Primer Set for Detecting the STY2879 Gene of Salmonella enterica Serovar Typhi in Raw Milk

Microorganisms
Milk-borne outbreaks remain a significant issue in low-income countries due to unhygienic practices. Currently, there are no known easily accessible and low-cost diagnostic tests that can detect Salmonella enterica subsp.

CRP-cAMP mediates silencing of Salmonella virulence at the post-transcriptional level [PDF]

, 2018
Invasion of epithelial cells by Salmonella enterica requires expression of genes located in the pathogenicity island I (SPI-1). The expression of SPI-1 genes is very tightly regulated and activated only under specific conditions.

Temperature, Disinfectant Concentration and Bacterial Innate Properties Influence the Disinfection of Bacterial Pathogens Relevant to Catfish Aquaculture

Journal of Fish Diseases, EarlyView.
ABSTRACT Aquaculture systems suffer a wide range of losses, mostly due to bacterial disease outbreaks, and the use of disinfectants is a routine practice for controlling the spread of pathogenic organisms globally. Including Aeromonas hydrophila, Streptococcus agalactiae and Edwardsiella tarda, implicated for natural disease outbreaks and economic ...

Enteric pathogen survival varies substantially in irrigation water from Belgian lettuce producers [PDF]

, 2014
It is accepted that irrigation water is a potential carrier of enteric pathogens, such as Salmonella and E. coli O157:H7 and, therefore, a source for contamination of fresh produce.

PLP Homeostasis Protein Is Required for Efficient Maturation of Aromatic Amino Acid Aminotransferase in Salmonella enterica

Molecular Microbiology, EarlyView.
Cellular pool of aromatic amino acid aminotransferase proteins represented as holo‐ or apo‐ enzymes, reflecting presence or absence of associated PLP. Status of PLPHP is implicated in determining the ratio of holo‐ and apo‐TyrB. ABSTRACT Pyridoxal 5′‐phosphate (PLP) is an essential cofactor required for metabolic functions including amino acid ...

Minimum Inhibitory Concentration of Glyphosate and a Glyphosate-Containing Herbicide in Salmonella enterica Isolates Originating from Different Time Periods, Hosts, and Serovars [PDF]

, 2019
Glyphosate, the active compound of Roundup, is one of the most used pesticides in the world. Its residues are often detected in animal feed, but the impact on the animal gut microbiota and on pathogens of the intestine has not intensively been ...

Protein STM3547 From Salmonella typhimurium Is a Phosphofructose Kinase B‐Type Enzyme With Ribose Kinase Activity

Molecular Microbiology, EarlyView.
The metabolism of ribose starts with the phosphorylation of its 5′ hydroxyl group. Salmonella typhimurium has two kinases that perform this function, namely ribose rinase (RbsK) and deoxyribose kinase (DeoK). Here we report a new ribose kinase that we named RikA. The illustration was partially created in BioRender.

Cytotoxigenicity in Salmonella serovars.

Indian journal of experimental biology, 1995
Twenty two strains of Salmonella belonging to eight different serovars, namely S. enterica subsp. enterica serovar S. typhimurium, S. nchanga, S. newport, S. virchow, S. bovismorbificans, S. seftenberg, S. weltevreden and S. indiana, isolated from foods of animal origin, were tested for their cytotoxicity on MDBK and Vero cell-lines.
