The bacterial pathogenicity phenomenon is the poly-functional biological potency of germs that are realized by factors (determinants) of pathogenicity (PF) in multi-cellular organism.   Biological functions are responsible for bacterial pathogenicity in a multi-cellular host organism: the adhesive function, the function of invasion and penetration into the cell, the function of evasion of host defense, and

Gongronema latifolium is a plant that has a wide range of nutritional and ethnomedical uses in different tropical African communities. Scientific reports on the chemical composition and bioactivity (anti-inflammatory, antimicrobial, antidiabetic, antioxidant, anticancer and allelopathic properties) of the plant material by different authors are discussed in this review. Future prospects of the plant extracts in

Aims: The focus of this study was to evaluate the antimycobacterial activity of Alcaligenes faecalis BW1 extract and to purify it partially. Study Design: Partial purification of A. faecalis BW1 extract was performed by using thin layer chromatography and active substances responsible for the biological activity were localized. Place and Duration of Study: The study

Introduction: Methicillin resistant Staphylococcus aureus (MRSA) is defined as the resistant to penicillinase-stable penicillin’s, thus the acronym MRSA is still under use even though methicillin is no longer the agent of choice for treatment. The use of vancomycin for MRSA remains as the treatment of choice but concerns with rising resistance to glycol peptides call

The causative agent of banana streak disease (BSD) is Banana streak virus (BSV). In tropical countries such as Kenya, the virus causes considerable damage to the banana crop besides lowering banana production yields. Several mealy-bug species have been reported as vectors of BSV. The latent and retention time of the BSV in the oleander mealy-bug

Aims: To highlight whether metabolites of Alcaligenes faecalis BW1 extract can be administered orally for their possible antimycobacterial effects. Study Design: Study of the influence of certain parameters on the extract of Alcaligenes faecalis by using either discs or well diffusion methods against M. smegmatis. Place and Duration of Study: Laboratory of Microbial Biotechnology, Department

Tomato is one of the most widely grown and extensively consumed horticultural crops in the world. Isolation, identification and pathogenicity of fungal organisms causing postharvest spoilage of tomato fruits during storage was carried out. Tomato fruits showing symptoms of rot were collected from the store house. Small sizes were cut and surface sterilized in 1%

Mycobacterium ulcerans (MU), the causative agent of Buruli ulcer (BU), skin disease, is considered to be an environmental pathogen. The pathogenic virulence of MU is being linked to the expression of toxin called Mycolactone. The ketoreductase (KR) gene, is one of the synthesis genes of mycolactone enzymes previously found in M. ulcerans. Genetic analyses using
