Identification of the aadB gene coding for the aminoglycoside-2"-O-nucleotidyltransferase, ANT(2"), by means of the polymerase chain reaction36645
a one-step single colony technique demonstrated that it was an acceptable alternative to the classic PCR test. The PCR method was used successfully to detect the presence of the aadB gene in 17 ...
Treatment of high-output gastric fistulas with omeprazole85
gastric antisecretory drugs. IV administration of omeprazole decreased acid output in one patient in a rapid and significant way, resulting in the spontaneous healing of the fistula after eight days of ...
Beta-glucuronidase activity in mouse oocytes, mouse preimplantation embryos, and human gametes17
starting from the morula stage on in a pooled sample of 15 embryos and at blastocyst formation in one single embryo. beta-Gluc activity was low in human sperm cells. The enzyme could be readily demonstrated ...
Pathogenicity of fowl enteroviruses.
one-day-old specific pathogen-free chickens. All viruses were shown by immunofluorescence and transmission electron microscopy to multiply in the cytoplasm of enterocytes but histological lesions of the ...
On-line high-performance liquid chromatographic diode array spectrophotometric analysis of steroidal hormones in illegal preparations
column, using methanol as modifier, was developed. For both types of compound an internal standard was chosen to establish reproducible relative retention times that could be used as one element of the ...
Serological response to a booster foot-and-mouth disease vaccination with strains different from the primary vaccine.
revaccination. At one and two months after revaccination there was no significant difference between the responses to revaccination with vaccine identical to the primary vaccine or with the foreign FMD vaccine. It ...
Isoelectric focusing applied to taxonomic differentiation of the Trichophyton mentagrophytes complex and the related Trichophyton interdigitale36633
first one matched with the Arthroderma vanbreuseghemii profile and gathered all the Trichophyton interdigitale strains studied and 4 Trichophyton mentagrophytes. The second one corresponded to the ...
Analytical evaluation of twenty assays for determination of thyrotropin (TSH)146
manufacturer’s specification. One assay was not acceptable for clinical use because the practical detection limit only reached 1.5 mU/l. Three other assays (from the same origin) demonstrated particular problems ...
Experimental transmission of enzootic bovine leukosis to cattle, sheep and goats: infectious doses of blood and incubation period of the disease.
intradermally with serial dilutions of blood collected on two BLV-positive donor cows. One donor had a high lymphocytosis and high antibody titers to gpBLV antigens; these two parameters were low for the second ...
Significance of Clostridium spiroforme in the enteritis-complex of commercial rabbits.
In 33.3% of C. spiroforme-containing samples, more than one of these agents was present. There was no significant difference between the presence of these organisms in C. spiroforme-positive and ...
