the ability of uropathogenic e. coli (upec) to cause symptomatic uti is associated with the expression of a variety of virulence factors. biofilm formation enables upec to resist the flow of urine and increases its tolerance to antimicrobials and the host immune response. the measurement of biofilm formation in vitro is affected by the type of culture medium used. the aim of this study was to e...

Background: For biotechnological application, selected lactic acid bacteria strains belonging to the genera Lactobacillus (Lb) are proposed as an alternative to the antibiotics for the prevention and treatment of urogenital tract infections. Objectives: Isolating and selecting vaginal lactobacilli strains for probiotic use based on their technological and probiotic aptitudes. Materials and Meth...

Cholesterol oxidase (EC1.1.3.6; CHO) is an enzyme, which catalyzes the oxidation of cholesterol and converts 5cholesten-3β-ol into 4cholesten-3-one. The objective of this study is to isolate extracellular cholesterol oxidase (CHO) producing microorganisms to obtain an abundant source of cholesterol oxidase (CHO) for industrial and medicinal needs. Cholesterol oxidase producing bacteria were iso...

Background and Aims: The protozoan parasites of the genus Leishmania are the causative agents of various clinical diseases. Different methods of cultivation of Leishmania parasites are available. In the present study, the efficacy of the LB broth with rabbit lyophilized anti-sheep red blood cell haemolysin was evaluated in the cultivation of promastigotes of Leishmania major. Materials and Met...

This experiment was studied to examine the in vitro developmental potential of enucleateddomestic cat oocytes reconstructed with skin fibroblasts from female domestic and leopard cats. The cumulus oocyte complex of domestic cat were cultured in IVM medium under 38.5°C, 5%CO2, 5%O2,90%N2 for 24 hours. The matured oocytes were enucleated and individual donor cell was inserted into...

Consider a wireless network of n nodes represented by a graph G = (V,E) where anedge (i, j) ∈ E models the fact that transmissions of i and j interfere with each other, i.e.simultaneous transmissions of i and j become unsuccessful. Hence it is required that ateach time instance a set of non-interfering nodes (corresponding to an independent set in G)access the wireless mediu...

The enzyme amylase was shown to be present in extracts prepared from both house dust and spent growth medium used in the culture of the mite Dermatophagoides pteronyssinus. In dust, it was shown to correlate with both mite counts and concentrations of the faecally derived mite allergen, Der p I. Mite amylase was isolated from the culture medium and shown to be a single chain protein with a mole...
