Different organic and aqueous extracts of leaves of Cassia occidentalis L (Caesalpiniaceae) were screened for their antimicrobial activity against seven human pathogenic bacterial and two fungal strains by disk diffusion assay. The pattern of inhibition varied with the solvent used for extraction and the microorganism tested. Among these extracts, methanol and aqueous extracts showed significan...

A large range of microorganisms can associate with plants, resulting in neutral, friendly or hostile interactions. The ability of plants to recognize compatible and incompatible microorganisms and to limit or promote their colonization is therefore crucial for their survival. Elaborated communication networks determine the degree of association between the host plant and the invading microorgan...

BACKGROUND Streptococcus uberis, the most frequent cause of mastitis in lactating cows, is considered non-pathogenic for humans. Only a few case reports have described human infections with this microorganism, which is notoriously difficult to identify. CASE PRESENTATION We report the case of a 75-year-old male haemodialysis patient, who developed a severe foot infection with osteomyelitis an...

Probiotics are digestive tract microorganisms that, when taken orally, beneficial to the health of their host. Probiotics; It is human origin, not being pathogenic and toxigenic, holding on intestinal cell epithelium, having antimicrobial properties, resistant gastric acid bile a positive effect host, it provides inhibition microorganisms, improves digestibility food by improving gastrointestin...

Most bacteria pathogenic to insects are classified in the families Pseudomonadaceae, Enterobacteriaceae, Lactobacillaceae, Micrococcaceae, and Bacilliaceae; spirochetes and rickettsia are in the families Spirochaetaceae and Rickettsiaceae, respectively. Except for Bacilliaceae, these families contain nonsporulating microorganisms. Most spore-forming bacteria pathogenic to insects belong to the ...

Immunology has traditionally been concerned with two central topicsimmunity against pathogenic microorganisms and the nature and properties of antibodies. Both of course are, and will remain, immensely important but at the present time there can be little question that the problems of the origin, nature, and behaviour of the "immunologically competent cell" provide the centre of current interes...

Recent studies of microorganisms have revealed diverse complex social behaviors, including cooperation in foraging, building, reproducing, dispersing and communicating. These microorganisms should provide novel, tractable systems for the analysis of social evolution. The application of evolutionary and ecological theory to understanding their behavior will aid in developing better means to cont...
