Real-time reverse transcription PCR for the quantification of the mntH expression of Salmonella enterica as a function of growth phase and phagosome-like conditions36757
in different S. enterica strains under various biological conditions, the ratio mntH mRNA level to the normalization factor was determined. The latter is the geometric mean of the RNA level of three ...
Differential inlA and inlB expression and interaction with human intestinal and liver cells by Listeria monocytogenes strains of different origins36774
and for expression levels of specific virulence genes. For THP-1 cells, no differences between clinical and nonclinical L. monocytogenes strains in invasion capacity or in production of the ...
Ultrastructural changes of the tracheal epithelium after vaccination of day-old chickens with the La Sota strain of Newcastle disease virus.
against invading microorganisms, they might explain at the ultrastructural level the secondary complications of vaccination with the La Sota strain against NDV. Health Topics: Animal health Category: A1 ...
Virulence-associated traits in avian Escherichia coli: comparison between isolates from colibacillosis-affected and clinically healthy layer flocks.
characteristics of avian pathogenic Escherichia coli associated with the occurrence of colibacillosis outbreaks at flock level. Forty E. coli strains originating from layers from healthy flocks (‘control ...
Arcobacter cibarius sp. nov., isolated from broiler carcasses.
hybridization with reference strains of the current four Arcobacter species revealed binding levels below 47 %. The G+C contents ranged between 26.8 and 27.3 mol%. Pairwise comparison of 16S rRNA gene sequences ...

Environmental investigations and molecular typing of Aspergillus flavus during an outbreak of postoperative infections36731
surveys were made to follow up the decontamination process; the contamination level did not fall rapidly, needing repetitive cleaning operations. Strains from patients and from the hospital environment ...
Antimicrobial drug resistance in nontyphoid human Salmonella in Belgium: trends for the period 2000-200236738
1756 isolates were screened for their antimicrobial resistance profile by the disc diffusion method. S. Hadar strains showed the highest level of antimicrobial resistance. Simultaneous resistance to ...
Effect of challenge dose and age in experimental infection of pigs with encephalomyocarditis virus.
Swine Diseases Abstract: Two experiments were performed to compare the severity of encephalomyocarditis virus (EMCV) infection in pigs. The pigs were challenged with the Greek myocardial strain, at ...
