Evaluation of antimicrobial activities of Rosa damascena cv. Taifi extract

Antimicrobial activities were evaluated from the known varied weights of rose petals (50 to 400 mg) and pollens extracts of Rosa damascena cv. Taifi in different aqueous solutions and solvents such as sterilized zamzam water, distilled water, ethanol, acetone, isoamyl alcohol and 100 millimolar (mM) Tris-HCl at pH 8.7 by using liquid nitrogen. The highest activity was recorded against ethyl...

Chrome agar Candida for species level identification of isolates of Candida sp. from oral cavity

Recently, Candida has become an important nosocomial pathogen. They are normal flora of skin, mouth, gut and vagina of healthy humans. They become opportunistic with immunocompromised and immunosuppresed individual. Since it is not possible to identify the species directly on Sabouraud’s dextrose agar (SDA), CHROM agar for candida is used for easy recognition of species by colour of the colonies. This study was...

Antimicrobial assay and phyto-chemical analysis of Solanum nigrum complex growing in Kenya

Solanum nigrum complex is a group of plants used as indigenous vegetables and also a source of traditional medicine in Kenya and other parts of the world. The main objective of this study was to determine the antimicrobial property and phytochemical composition of S. nigrum complex. Samples of S. nigrum complex were collected from Kenya. The plants were dried under the shade and then ground to a fine powder. Crude...

Relative plant growth promoting potential of Himalayan Psychrotolerant Pseudomonas jesenii strain MP1 against native Cicer arietinum (L.)., Vigna mungo (L.) Hepper; Vigna radiata (L.) Wilczek., Cajanus cajan (L.) Millsp. and Eleusine coracana (L.)Gaertn.

Plant growth promoting properties of Pseudomonas jesenii strain MP1 were tested against five native crops viz. Cicer arietinum (L.) (Chickpea), Vigna mungo (L.) Hepper. (Blackgram), Vignaradiata (L.) Wilczek. (Greengram), Cajanus cajan (L.) Millsp. (Pigeonpea) and Eleusine coracana (L.) Gaertn. (Finger millet). The strain significantly (p<0.05) stimulated the growth of shoot length, root length, plant fresh weight...

Prevalence of mecA, PVL and ica genes in Staphylococcus aureus strains isolated from urinary tract infections patients

The prevalence of Staphylococcus aureus among urinary tract infections (UTIs) patients has been increasing worldwide. The aim of this study was to determine the occurrence of the mecA, PVL, ica genes in a collection of MRSA urinary isolates by PCR. Methicillin resistance S. aureus (MRSA) is considered to have emerged from S. aureus through the acquisition of staphylococcal cassette chromosome (SCCmec), which carries the...
