Immunogenicity and protective efficacy of DNA vaccines encoding secreted and non-secreted forms of Mycobacterium tuberculosis Ag85A.
DNA Abstract: OBJECTIVE: To determine the efficacy of Ag85A- DNA against challenge with a highly virulent human clinical isolate of Mycobacterium tuberculosis (CSU37) and to compare the potencies of two ...
Comparison of eae, tir, espA and espB genes of bovine and human attaching and effacing Escherichia coli by multiplex polymerase chain reaction44
The sequences alignments revealed the presence of constant and variable regions. Multiplex polymerase chain reactions were developed, in order to determine the subtype of each gene present in ...
Detection and genotyping of bovine diarrhea virus by reverse transcription-polymerase chain amplification of the 5' untranslated region.
bovine diarrhea virus (BVDV) from other pestiviruses, and to determine the genotype of the BVDV isolates. For this purpose, primer pairs were selected in the 5’ untranslated region (5’ UTR). The primers BE ...
Aminoglycoside resistance in Gram-negative blood isolates from various hospitals in Belgium and the Grand Duchy of Luxembourg. Aminoglycoside Resistance Study Group36690
isepamicin was determined using a microdilution technique according to NCCLS procedures. The overall mean resistance level was 5.9% for gentamicin, 7.7% for tobramycin, 7.5% for netilmicin, 2.8% for amikacin ...
Nested designs in ruggedness testing
determine tetracycline and related substances in bulk samples of tetracycline. Factors such as different laboratories, analysts, instruments, columns, days and batches were examined. The interpretation ...
Interlaboratory study comparing the microbiological potency of spiramycins I, II and III36687
aureus study Test values Abstract: An interlaboratory study has been performed to determine the relative potencies of spiramycins (SPM s) I, II and III by diffusion or/and turbidimetric assays with ...
Genetic multilocus studies of different strains of Cryptococcus neoformans: taxonomy and genetic structure232334008
areas were determined by multilocus enzyme electrophoresis (MLEE). We analyzed the relationships between genotype structure and serotype and between genotype structure and strain origin. Twelve of the 14 ...
Identification of encephalomyocarditis virus in clinical samples by reverse transcription-PCR followed by genetic typing using sequence analysis.
was clearly shown to be the most suitable organ. The detection limit was determined to be 1 viral particle in 100 mg of heart tissue. The sensitivity and specificity of the assay on the basis of the ...
The locus for enterocyte effacement (LEE) of enteropathogenic Escherichia coli (EPEC) from dogs and cats43
Third, since the four types of eae and tir genes were described, we developed a multiplex PCR in order to determine the type of eae and tir genes present in each strain. Fourth, we determined by PCR the ...
