Isolation, drug resistance and molecular characterization of Salmonella isolates in northern Morocco36818

gel electrophoresis (PFGE), and virulence gene analysis were also performed. Results: Sixteen Salmonella strains were isolated in our laboratory, serotyped and identified as S. Kottbus, S. Indiana, S. ...

Epidemiological study of bovine norovirus infection by RT-PCR and a VLP-based antibody ELISA.

diarrhoeic calves screened by RT- PCR. Nucleotide sequencing performed on the polymerase region classified all the norovirus amplicons in the bovine norovirus genotype 2. Rather surprisingly, some rotavirus ...

Analysis of 13 million individual patient records pertaining to Pap smears, colposcopies, biopsies and surgery on the uterine cervix (Belgium, 1996-2000).

cervical biopsies and surgery, performed in Belgium between 1996 and 2000. Cervical cancer screening coverage was defined as the proportion of the target population (women of 25-64 years) that has had a Pap ...

The major portal of entry of koi herpesvirus in Cyprinus carpio is the skin.

further demonstrate the role of the skin as the KHV portal of entry, we constructed an original system, nicknamed “U-tube,” to perform percutaneous infection restricted to the posterior part of the fish. ...

Triage of women with equivocal or low-grade cervical cytology results: a meta-analysis of the HPV test positivity rate.

papillomavirus (HPV) DNA testing in the management of women with equivocal cervical cytological abnormalities, but not in case of low-grade lesions. We performed a meta-analysis including studies where the ...

Technical note: Flow cytometric identification of bovine milk neutrophils and simultaneous quantification of their viability.

iodide was used to determine milk PMNL viability. Thirty milk samples were run in parallel to assess the repeatability of the immunoassay and 6 repeated measurements per sample were performed to assess the ...

Some guidelines for determining foot-and-mouth disease vaccine strain matching by serology.

of foot-and-mouth disease (FMD) virus can be assessed in vivo or by serological r-value determination. Sera from animals involved in vaccine potency and cross-protection trials performed using the ...
