Species Distribution Models (SDMs) are used regularly to develop management strategies, but many modelling methods ignore the spatial nature of data. To address this, we compared fine-scale distribution predictions harbour porpoise (Phocoena phocoena) using empirical aerial-video-survey data collected along east coast Scotland in August and September 2010 2014. Incorporating environmental covar...

The present study was carried out to know the lowest detection limit of Listeria monocytogenes by PCR. The quantification of organisms was done by CFU counting from ten fold serial dilution and PCR amplification of inlA gene fragment was performed from each dilution. The PCR could detect as low as 20 organisms indicating the lowest PCR detection limit. Thus, lowest number of L. monocytogenes de...

Listeria monocytogenes mutants defective in the actA gene, the plcB gene, and the inlA and inlB genes were less virulent when injected intravenously into BALB/c mice. The growth of these strains as well as of the virulent wild-type strains was increased by treating mice with a neutrophil-specific depleting monoclonal antibody, RB6-8C5. Histologic examination of the livers of the treated animals...

ers such as the intestinal epithelium and the placental and blood-brain barriers. It is thought that the ability of these bacteria to invade non-phagocytic cells plays an essential role in breaching those natural barriers. Efforts to identify L. monocytogenes determinants that mediate internalization resulted in the characterization of two related proteins, InlA, also known as internalin, and I...

Members of the genus Listeria provide a model for defining host responses to invasive foodborne enteropathogens. Active translocation of Listeriamonocytogenes across the gut epithelial barrier is mediated by interaction of bacterial internalin (InlA) and its species-specific host receptor, E-cadherin, whereas translocation across Peyer’s patches through M-cells is InlAindependent. To define mic...

El objetivo de este trabajo es identificar patrones distribución espacial la sobrepoblación relativa, medida por Población Económicamente Activa y migración, en localidades del estado Chiapas 2020. Se aplican técnicas análisis exploratorio datos espaciales modelos gaussianos latentes se utiliza tasa inmigración como covariable dos empíricos distintos. ajuste dichos realiza empleando el paquete ...

B Background The pathogenic bacterium Listeria monocytogenes is able to cross the endothelial, placental and blood-brain barrier causing gastritis, meningitis, neonatal death and other diseases in humans. PrfA (Positive regulatory factor A) is the sole regulator of the virulence genes identified in Listeria monocytogenes till date. It regulates genes within the virulence gene cluster (vgc), whi...
