the identification of the efficiency of some mtdna genes of mus musculus species complex (house mouse) for biosystematics research was studied in this approach. recent studies have made use of different mitochondrial genes including nadh dehydrogenase genes, cytochrome b gene, cytochrome oxidase genes, d-loop region and whole mtdna genome to study the house mouse species. usage of each of these...

background : gram-negative bacteria are the most cause of nosocomial infection especially in burned patients. carbapenem resistant strains can limit seriously the choice of antibiotic therapy. ampc can make resistance to carbapenem and detection of that can be useful for identification of carbapenem resistant. the aim of this study was identification of ampc in most prevalent cause of nosocomia...

Precise identification of microorganisms involved in candidiasis together with antifungal susceptibility evaluation could help clinicians to prescribe appropriate medicine, especially in patients with critical conditions. The present study has been conducted to evaluate discriminatory power of Integral System Yeast Plus (ISYP) for rapid identification and determination of antifungal susceptibil...

We present results of the SIRIUS2 submission to the 2012 CASMI contest. Only results for Category 1 (molecular formula identification) were submitted. The SIRIUS method and the parameters used are briefly described, followed by detailed analysis of the results and a discussion of cases where SIRIUS2 was unable to come up with the correct molecular formula. SIRIUS2 returns consistently high qual...

The identification of maximally homologous subsequences among sets of long sequences is an important problem in molecular sequence analysis. The problem is straightforward only if one restricts consideration to contiguous subsequences (segments) containing no internal deletions or insertions. The more general problem has its solution in an extension of sequence metrics (Sellers 1974; Waterman e...

As the pace of biotic homogenization has accelerated over time, the threat of novel phytopathogens has become a question of growing importance for mycologists and plant pathologists. Meanwhile, this question is but one of a whole set of related questions that invasion biologists are attempting to answer. Pathogen release is of interest to both sets of scientists because it provides a measure of...

Pseudouridine, a non-classical nucleoside present in human urine as a degradation product of RNAs, is one of the fewmolecules that has a glycosidic C-C bond. Through a data base mining approach involving transcriptomic data, we have molecularly identified two enzymes that are involved in themetabolism of pseudouridine in uropathogenic Escherichia coli, the principal agent of urinary tract infec...

Systemic fungal infections represent a major cause of morbidity and mortality in immunocompromised patients. The ever-increasing number of yeast species associated with human infections that are not covered by conventional identification kits, and the fact that moulds isolated from deep infections are frequently impossible to identify using classical methods due to lack of sporulation, has driv...

background: systemic candidiasis is a major complication in neutropenic cancer patients undergoing treatment. most systemic fungal infections emerge from endogenous microflora so the aim of the present study was to identify candida species isolated from the different regions of body   in neutropenic patients in compare with the control group. methods: a total of 309 neutropenic cancer patients ...

conclusions although previous studies have shown that a-g transition mutations in 23 srrna gene (domain v) are the main reason for the occurrence of high level macrolides resistance in b. pertussis, however, the mentioned single nucleotide polymorphisms (snps) have not been detected in our resistant strain. this is the first report of high level macrolide resistant b. pertussis, without snps in...
