Conjugative transfer of bacterial plasmids is the most efficient way of horizontal gene spread, and it is therefore considered one of the major reasons for the increase in the number of bacteria exhibiting multiple-antibiotic resistance. Thus, conjugation and spread of antibiotic resistance represents a severe problem in antibiotic treatment, especially of immunosuppressed patients and in inten...

Purpose. Canaliculitis is classically associated with Actinomyces species, which are filamentous bacteria; the purpose of this study was to evaluate the extent to which nonfilamentous bacteria colonize canalicular concretions by using graded histopathological analysis. Methods. This is a series of 16 cases. The percentage of Gram-positive/Gomori's methenamine silver-positive filamentous bacteri...

Sudarshan Churna (SC) is very potent Ayurvedic medicine ; composed of 42 medicinal plants, which is used traditionally in treatment of malaria, viral fever, and bacterial infection. The Present study was designated to evaluate the antimicrobial activity of aqueous extract of Sudarshan Churna (ASC) using the paper disc diffusion method. The ASC was found active against the gram-negative b...

We report on the mobilization of shuttle plasmids from gram-negative Escherichia coli to gram-positive corynebacteria mediated by P-type transfer functions. Introduction of plasmids into corynebacteria was markedly enhanced after heat treatment of the recipient cells. High-frequency plasmid transfer was also observed when the restriction system of the recipient was mutated. On the basis of our ...
