The emergence of one of the most recently described carbapenemases, namely, the New Delhi metallo-lactamase (NDM-1), constitutes a critical and growingly important medical issue. This resistance trait compromises the efficacy of almost all lactams (except aztreonam), including the last resort carbapenems. Therapeutical options may remain limited mostly to colistin, tigecycline, and fosfomycin. ...

AIMS This study was carried to reveal the genetic mechanisms of trimethoprim/sulfamethoxazole (SXT) resistance. METHODS Among 300 clinical Stenotrophomonas maltophilia isolates from China, resistance determinants such as sul and dfrA genes, integrons and transposase were examined using PCR, DNA sequencing and thermal asymmetric interlaced PCR (TAIL-PCR). Data were analyzed using SPSS 20.0. ...

We present some exact formulas for hitting probabilities and hitting numbers of one or several levels for a Lévy process {Xt | t ≥ 0} with no negative jumps, starting at zero. Let Nx be the number of visits of level x ∈ R and define τx = inf{t > 0 | Xt = x}. We determine the Laplace transform of f(x) = P[τx < ∞], x > 0. The counting variable Nx is finite if and only if EX1 6= 0 and the paths of...

The utilization of rocks as fertilizers is limited by their low solubility. However, solubilization may be achieved by some micro-organisms, such as ectomycorrhizal fungi (ECMf). The aim of this study was to evaluate the potential of seven isolates of ECMf to solubilize two rocks, alkaline breccia and granite, and to liberate potassium and phosphorus for Eucalyptus dunnii seedlings under greenh...

Bacterial strains D11, E1 and E2 isolated from petroleum-contaminated soils were found to be members of Acinetobacter genus revealed by 16S rRNA gene sequence analysis phenotypic characteristics. After incubation for 5 days, about 43%, 9% 12% total petroleum hydrocarbons crude oil degraded E2, respectively, determined GC-MS analysis. Moreover, 70% 76% single hydrocarbon hexadecane was the D11 a...

A previous study of deletions in the protocatechuate (pca) region of the Acinetobacter sp. strain ADP1 chromosome revealed that genes required for utilization of the six-carbon dicarboxylic acid, adipic acid, are linked to the pca structural genes. To investigate the genes involved in adipate catabolism, a 33.8-kb SacI fragment, which corrects a deletion spanning this region, was cloned. In add...

Bacterial and Fungal Organisms in the Vagina of Normal Cows and Cows with Vaginitis. (December 2003) James Ross Husted, B.S. Texas A&M University Chair of Advisory Committee: Dr. R. Bruce Simpson Previous studies on infections of the reproductive tract in various animal species have focused on uterine and cervical infections. This study defined the bacterial flora from the vaginal fornix of 110...
