Relationship between the probiotic Lactobacillus rhamnosus and Enterococcus faecalis during the biofilm formation
One of the factors that make the treatment of Enterococcus faecalis infections difficult is their ability to form biofilm, as well as their natural and acquired resistance to antibiotics which does not have specific drugs for their inhibition. This fact makes essential the search for alternative treatments, as the use of probiotics strains of Lactobacillus rhamnosus has been effective in the treatment of some diseases....

Relative efficiency and response of promiscuous soybean to rhizobia inoculant in Savanna region of Nigeria
Inoculation of promiscuous soybean with rhizobia has been proven to improve yield. Screenhouse pot experiments were conducted to assess the response of promiscuous soybean, TGx1448-2E to rhizobia inoculation and to determine the relative efficiency of indigenous rhizobia from soils collected from the Northern and Southern Guinea and Sudan Savanna agro-ecological zones of Nigeria. Soils were collected at 0 to 20 cm depth...

Diagnosis of Helicobacter pylori infection in children and their mothers using some non-invasive techniques
Helicobacter pylori (H. pylori) is an important global public health concern. It infects approximately one half of the world’s population. Considering the broad spectrum of available H. pylori diagnostic methods and since a reliable diagnosis is mandatory both before and after eradication therapy; thus it is crucial to study the different methods to be able to select the highly accurate laboratory tests that could...

Bioprospecting and plant growth-promoting bacteria tolerant to salinity associated with Atriplex nummularia L. in saline soils
This study aimed to bioprospect and select halotolerantes bacteria and promoting plant growth associated with the plant Atriplex nummularia L. in saline soils. For bioprospecting of bacteria, samples were collected in five niches and two field experiments located in Serra Talhada and Ibimirim, Pernambuco, Brazil. After collecting the material it was performed the isolation and selection of bacteria based on plant growth...

Morphogenesis of edible gall in Zizania latifolia (Griseb.) Turcz. ex Stapf due to Ustilago esculenta Henn. infection in India
The Zizania latifolia Griseb. Turcz. ex Stapf., a perennial wetland wild rice species get infected by a basidiomycetous fungus Ustilago esculenta Henn that produces gall. Here we report the morphogenesis behaviour of this plant during gall transformation. The identity of Z. latifolia and U. esculenta were confirmed by comparing microsatellite and Internal Transcribed Spacer region of nuclear ribosomal DNA sequence with...

In vitro antimicrobial activity of essential oil of Cymbopogon citratus (lemon grass) on Streptococcus mutans biofilm
The present study aimed to investigate the effect of essential oil of lemon grass (LGO) on Streptococcus mutans biofilm developed in hydroxyapatite discs surface. Initially, the susceptibility of S. mutans to the LGO through the inhibition zone test in planktonic suspension and minimum inhibitory concentration (MIC) was investigated. To evaluate the effect of the essential oil in biofilms, hydroxyapatite discs were used...

Antimicrobial activity of extracts from Crotalaria bernieri Baill. (Fabaceae)
This work was designed to study the antimicrobial activity of Crotalaria bernieri Baill. (Fabaceae). Extracts from leaf, root, pod and seed using hexane, ethyl acetate and methanol were tested in vitro for their activity against 17 bacteria, 5 fungi (3 yeasts and 2 molds) using disc diffusion and micro dilution methods. At the concentration of 1 mg/disc, all the extracts exhibited antimicrobial activity depending on the...
