Multidrug-resistant Enterococci colonizing the intestinal tract of patients are major sources infection as well spread resistance. The present study aims to determine antimicrobial resistance profile Enterococcus species from admitted laboratory Yaounde Military Hospital. was conducted in July November 2020. Stool samples were collected and processed for bacterial isolation susceptibility testi...

Two species of dairy streptococci, Streptococcus waius and Streptococcus macedonicus, were originally characterized by 16S-23S intergenic spacer sequence analysis, random amplified polymorphic DNA fingerprinting, PFGE analysis and DNA-DNA reassociation experiments. All genetic data suggested that S. waius strains belong to the previously described species S. macedonicus. Likewise, the phenotypi...

Two strains named ESC1(T) and ESC5 were isolated from nodules of Cytisus scoparius growing in a Spanish soil. Phylogenetic analysis of the 16S rRNA gene showed that these strains belong to the genus Ochrobactrum, their closest relatives being Ochrobactrum anthropi and Ochrobactrum lupini, with 100 and 99.9 % similarity to the respective type strains. Despite this high similarity, the results of...

Twenty-three isolates of Achromobacter species (CDC group Vd) were examined morphologically and biochemically. Gram stains revealed gram-variable bacilli frequently curved or hooked at one pole and often coryneform in shape and arrangement. Electron microscopy revealed the presence of extracellular material in polar accumulations and demonstrated the polar flagella arrangement seen by light mic...

Bacteria present in natural environments such as soil have evolved multiple strategies to escape predation. We report that natural isolates of Enterobacteriaceae that actively hydrolyze plant-derived aromatic b-glucosides such as salicin, arbutin and esculin, are able to avoid predation by the bacteriovorous amoeba Dictyostelium discoideum and nematodes of multiple genera belonging to the famil...

The Analytab Products, Inc. (API), anaerobic multitest microsystem (MICRO) was compared with the Center for Disease Control conventional (CONV) thioglycolate (supplemented with hemin and vitamin K1) system and with pre-reduced anaerobically sterilized (PRAS) media as recommended by the Virginia Polytechnic Institute. Growth from a solid medium was suspended to produce standard inocula. Substrat...

Multiple isolates of the genus Providencia were obtained from the haemolymph of wild-caught Drosophila melanogaster fruit flies. Sixteen isolates were distinguished from the six previously described species based on 16S rRNA gene sequences. These isolates belonged to two distinct groups, which we propose each comprise previously undescribed species. Two isolates, designated A(T) and B(T), were ...
