[An algorithm for identification of CTX-M-type beta-lactamase genes using restriction fragment length polymorphism analysis of PCR-product].
The algorithm of the identification of the bla(CTX-M) genes coding CTX-M-type beta-lactamases providing resistance to cephalosporins III-IV was developed. This algorithm provides identification of 49 genes of 96 genes presented in the GenBank database so far. Remaining 47 genes can b...
Growth potential of Listeria monocytogenes strains in mixed ready-to-eat salads
In this study, a microbiological challenge test in three artificially contaminated retail mixed mayonnaise-based ready-to-eat salads stored at refrigerator temperatures (3°C and 7°C) for 48h was carried out. Shrimp-tomato salad, smoked ham salad and garlic cheese salad were separat...
Effects of probiotic administration in swine
We evaluated the effects of probiotic strains administration in pigs. On the 35th day of age, 30 pigs were distributed into 2 groups: the non-treated control group (initial average BW: 8.3+/-0.6 kg) and a probiotic supplemented fed group (initial average BW: 8.7+/-0.4 kg). Each experimental group wa...
[Chromogenic medium for detection of enterobacteria producing beta-lactamases in North-Eastern Romania].
We evaluated the performances and analyzed practicability of an ESBL-detecting chromogenic agar medium (chromID ESBL, bioMerieux) for the screening of ESBL production. We have tested 112 enterobacteria strains, isolated in 2009 year, in North Eastern region of Romania. Each bacterial strain was cult...
Evolutionary convergence and nitrogen metabolism in Blattabacterium strain Bge, primary endosymbiont of the cockroach Blattella germanica.
We describe the genome sequence and inferred metabolism of Blattabacterium strain Bge, the primary Flavobacteria endosymbiont of the omnivorous German cockroach Blattella germanica. Through comparative genomics with other insect endosymbionts and free-living Flavobacteria we reveal that Blattabacter...
Effect of gutting on microbial loads, sensory properties, and volatile and biogenic amine contents of European hake (Merluccius merluccius v...
The effect of gutting on sensory, microbiological, and chemical properties of European hake (Merluccius merluccius var. mediterraneus) stored in ice was studied. Gutting of hake noticeably affected the development of gram-negative bacteria: counts of Enterobacteriaceae, Shewanella putrefaciens, and...
Two species of symbiotic bacteria present in the soybean aphid (Hemiptera: Aphididae).
Aphids, which feed solely on plant phloem sap, have developed symbiotic associations with bacteria that provide them with the amino acids that are lacking in phloem. Three soybean aphid (Aphis glycines Mat samura) populations were screened for the presence of Buchnera aphidicola and three common spe...
[Effect of tigecycline on selected multiresistant bacteria].
A total of 350 isolates were tested (100 MRSA, 10 0 VRE, 100 ESBL-positive and 50 AmpC-positive enterobacteria). In the cases of VRE and MRSA, no resistance to tigecycline was detected and the minimum inhibitory concentrations (MIC) did not exceed 0.25 mg/l and 0.5 mg/l, respectively. In ESBL-positi...

Phenotypic Characterization of Human Pathogenic Bacteria in Fish from the Coastal Waters of South West Cameroon: Public Health Implications
We investigated the microbiological quality of fish from the Limbe and Tiko beaches in South West Cameroon from May to October 2007. We isolated human pathogenic bacteria from three anatomic sites (skin, gills, intestine) of 50 fish (150 specimens) and investigated their susceptibility patterns to a...
