Efficient control of Japanese encephalitis virus in the central nervous system of infected pigs occurs in the absence of a pronounced inflammatory immune response.
where JEV replication was not completely controlled by this mechanism, a short but strong induction of chemokine gene expression was detected. An increased IFN y expression was simultaneously observed ...
Complex Circulation of Foot-and-Mouth Disease Virus in Cattle in Nigeria.
course of the study, while at some point in the study, outbreaks due to FMDV serotype A were observed in three remote States. The genetic and phylogenetic analysis suggests a mixed origin of FMD outbreaks. ...
A liquid bead array for the identification and characterization of fljB-positive and fljB-negative monophasic variants of Salmonella Typhimurium.
4 Salmonella; Monophasic; Typhimurium; 1 [5] Abstract: Salmonella1,4,[5],12:i:- accounts currently for one of the most common serotypes observed worldwide. These isolates do not express the FljB flagellin and ...
Comparative genomics of quinolone-resistant and susceptible Campylobacter jejuni of poultry origin from major poultry producing European countries (GENCAMP)
fluoroquinolone resistance among C. jejuni is related to the transmission through countries or to the selection through fluoroquinolone use in the individual countries. A high genomic diversity was observed. The ...
Risks for animal health related to the presence of zearalenone and its modified forms in feed
oestrogenic activity of the modified forms of ZEN differs considerably. For ZEN, the EFSA Panel on Contaminants in the Food Chain (CONTAM) established no observed adverse effect levels (NOAEL s) for pig ...
Towards the development of innovative multi-mycotoxin reference materials as promising metrological tool for emerging and regulated mycotoxin analyses.
decreases were observed only for T-2 contents at +24 °C, in contrast to the storage at-20 and +4 °C. For the other involved toxins, the candidate material was found to be stable at-20, +4, or +24 °C. Based on ...
Endocrine activity of mycotoxins and mycotoxin mixtures.
mixtures reacted as predicted by the concentration addition (CA) theory. Generally, the CA was within the 95% confidence interval of the observed ones, only minor deviations were detected. Although these ...
Stronger Interference of Avian Influenza Virus-Specific Than Newcastle Disease Virus-Specific Maternally Derived Antibodies with a Recombinant NDV-H5 Vaccine.
antigenically divergent highly pathogenic AI (HPAI) H5N1 challenges. In chickens with both H5 and NDV MDA, a strong interference was observed with reduced clinical protection when compared to vaccinated ...
Role of wildlife and domestic pigs as reservoirs for hepatitis E virus (HEV): study of the infection in suids and cervids and of the susceptibility of pigs to HEV originating from wild boa
out of 29 livers from red deer, it belonged to genotype 3f. No HEV RNA was detected in red and roe deer sera. Using a multivariate logistic regression, a significant effect of age was observed: young ...
Extensive genetic variability linked to IS26 insertions in the fljB promoter region of atypical monophasic variants of Salmonella enterica serovar Typhimurium.
expression of the phase 2 flagellin were observed in 53 isolates. Other genetic events in the invertible region carrying the fljB promoter were observed in 2 isolates. For the remaining 4 isolates, no ...
