Detection of Clinical and Subclinical Lumpy Skin Disease Using Ear Notch Testing and Skin Biopsies.
notches are less fit for purpose, as LSDV DNA is only detectable in these samples several days after it is detectable in blood samples. On the other hand, blood samples are less advisable for the detection ...
Residues of chlortetracycline, doxycycline and sulfadiazine-trimethoprim in intestinal content and feces of pigs due to cross-contamination of feed.
A mean concentration of 10 mg/kg CTC and 4 mg/kg DOX in the feces was reached, which is higher than concentrations that were shown to cause resistance selection. On the other hand, lower mean levels of SDZ ...
Comparison of PRRSV Nucleic Acid and Antibody Detection in Pen-Based Oral Fluid and Individual Serum Samples in Three Different Age Categories of Post-Weaning Pigs from Endemically Infected Farms.
relative sensitivity to detection in serum since oral fluid samples were always positive as soon as one pig in the pen was positive in serum. On the other hand, two false positive oral fluid samples in 11 ...
Follow-up of the Schmallenberg Virus Seroprevalence in Belgian Cattle.
2012. On the other hand, age-cohort-specific seroprevalence stayed stable from 1 year to the other. During winter 2012-2013, calves between 6 and 12 months had a seroprevalence of 20.59% (95% CI: ...
Evaluation of a hierarchical ascendant clustering process implemented in a veterinary syndromic surveillance system.
divided and defined as Bluetongue (BTV) positive cases (PC) on the one hand and BTV negative cases (NC) on the other hand. By comparing the clustering result of MoSS- E2 with the expected outcome, the ...
A model for the transfer of passive immunity against Newcastle disease and avian influenza in specific pathogen free chickens.
in early life, when the immune system is immature and unable to fight off infection. On the other hand, MDA can also affect the development of the immune system and interfere with vaccination against ...
In vitro surrogate models to aid in the development of antivirals for the containment of foot-and-mouth disease outbreaks.
(CPE). Madin-Darby bovine kidney cells on the other hand supported viral replication in the absence of CPE. Antiviral tests were developed for ERAV in Vero A cells employing a viral RNA-reduction assay and ...
Different replication profiles in specific-pathogen-free chickens of two H7 low pathogenic avian influenza viruses isolated from wild birds.
oropharyngeal and cloacal excretions compatible with efficient transmission as well as strong immune responses. On the other hand, the H7N7 isolated from the Canada goose presented a lower replication profile ...
Efficacy of rHVT-AI vector vaccine in broilers with passive immunity against challenge with two antigenically divergent Egyptian clade 2.2.1 HPAI H5N1 strains.
inactivated vaccines at the hatchery is no longer an option because of interference with passive immunity indirectly induced by the necessary vaccination of the breeders. On the other hand, injection of ...
Methodologies for Salmonella enterica subsp. enterica subtyping: gold standards and alternatives.
hand-crafted character of classical serotyping is being challenged, although it is widely accepted that classification into serovars should be maintained. This review summarizes and discusses modern typing ...
