Examining marginal sequence similarities between bacterial type III secretion system and Trypanosoma cruzi surface proteins: Horizontal gene transfer or convergent evolution? [PDF]
arXiv, 2012 The cell invasion mechanism of Trypanosoma cruzi has similarities with some intracellular bacterial taxa especially regarding calcium mobilization. This mechanism is not observed in other trypanosomatids, suggesting that the molecules involved in this type of cell invasion were a product of (1) acquired by horizontal gene transfer; (2) secondary loss ...

A multiplex oligonucleotide ligation-PCR as a complementary tool for subtyping of Salmonella Typhimurium [PDF]
, 2015 Subtyping below the serovar level is essential for surveillance and outbreak detection and investigation of Salmonella enterica subsp. enterica serovar Typhimurium (S. Typhimurium) and its monophasic variant 1,4,[5],12:i:- (S.

Accurate inference in negative binomial regression [PDF]
arXiv, 2020 Negative binomial regression is commonly employed to analyze overdispersed count data. With small to moderate sample sizes, the maximum likelihood estimator of the dispersion parameter may be subject to a significant bias, that in turn affects inference on mean parameters.

Tissue-specific Salmonella Typhimurium gene expression during persistence in pigs [PDF]
, 2011 Salmonellosis caused by Salmonella Typhimurium is one of the most important bacterial zoonotic diseases. The bacterium persists in pigs resulting in asymptomatic 'carrier pigs', generating a major source for Salmonella contamination of pork.

Genome-Wide Methylation Patterns in Salmonella enterica Subsp. enterica Serovars
PLOS ONE, 2015 The methylation of DNA bases plays an important role in numerous biological processes including development, gene expression, and DNA replication. Salmonella is an important foodborne pathogen, and methylation in Salmonella is implicated in virulence. Using single molecule real-time (SMRT) DNA-sequencing, we sequenced and assembled the complete genomes

A rapid molecular approach to determining the occurrence of pathogen indicators in compost [PDF]
arXiv, 2014 An accurate method for enumerating pathogen indicators, such as Escherichia coli (E. coli), and Salmonella spp. is important for assessing the safety of compost samples. This study aimed to determine the occurrence of pathogen indicators in compost samples by using a molecular approach known as Polymerase Chain Reaction (PCR).

Characterization of virulence factors in the newly described Salmonella enterica serotype Keurmassar emerging in Senegal (sub-Saharan Africa) [PDF]
, 2006 From 2000 to 2001, nine strains of Salmonella enterica belonging to the new serotype Keurmassar have been isolated from human and poultry samples at the Senegalese National Salmonella and Shigella Reference Laboratory at the Pasteur Institute, in Dakar.
