Keratin pattern in hyperkeratotic and ulcerated gastric pars oesophagea in pigs.
and the ulcerated pars oesophagea but not in the normal epithelium. These results indicate that K 6 is expressed in association with the mucosal changes. The pattern of the intermediate filaments of ...
Serological and biochemical follow-up in cattle naturally infected with Fasciola hepatica, and comparison with a climate model for predicting risks of fasciolosis.
untreated. The Lymnaea truncatula snails were counted on three different occasions. The results indicated a poor molluscicide efficiency. Body weight gains, anti-Fasciola antibody levels, faecal egg counts, ...
Characterization of In Vivo acquired resistance of Mycoplasma hyopneumoniae to macrolides and lincosamides.
gene of the resistant strain. No differences linked to resistance were found in the ribosomal proteins L4 and L22. The present study showed that 23S rRNA mutations resulting in resistance to macrolides ...
Resistance mechanism against fluoroquinolones in Mycoplasma hyopneumoniae field isolates.
In all five resistant isolates, one point mutation (C-→ A) in parC was found, resulting in an amino acid change from serine to tyrosine at position 80 (Escherichia coli numbering). For four of these ...
Sensitivity of avian Eimeria spp. to seven chemical and five ionophore anticoccidials in five Belgian integrated broiler operations.
of three Ross chicks. Medication started at 8 days of age, and each inoculated bird received 50,000 sporulated oocysts at 10 days. Results were related to the anticoccidial program that had been in ...
Analysis of foodborne disease in Belgium in 1997.
element of this surveillance is communication of the results, risks and measures for prevention between all the departments, institutions and public health authorities concerned. Health Topics: Animal ...
Dietary silver nanoparticles can disturb the gut microbiota in mice.
RESULTS: No overall toxicity was recorded in mice exposed to Ag NP. Ag NP disturbed bacterial evenness (α-diversity) and populations (β-diversity) in a dose-dependent manner. Ag NP increased the ratio ...
Comparative Analysis of Different Serological and Molecular Tests for the Detection of Small Ruminant Lentiviruses (SRLVs) in Belgian Sheep and Goats.
infection before seroconversion at two weeks post infection and showed a specificity of 100%. Sensitivity however remained suboptimal at 85%. These results allow to propose a faster and cheaper diagnostic ...
(Non-)Sense of Milk Testing in Small Ruminant Lentivirus Control Programs in Goats. Comparative Analysis of Antibody Detection and Molecular Diagnosis in Blood and Milk.
with a 10-fold higher analytical sensitivity of the ID screen test. In contrast to the overall good ELISA results, qPCR on milk cell pellets lacked sensitivity (81%) and specificity (88%), compared to ...
Transmission of Bluetongue Virus Serotype 8 by Artificial Insemination with Frozen-Thawed Semen from Naturally Infected Bulls.
and this had a significant impact on the infection rate, the time of onset of viraemia post artificial insemination, and the gestational stage at which pregnancy loss occurred. These results, which ...
