Uropathogenic Escherichia coli, the predominant causative agent of urinary tract infections, use type 1 pili to bind and invade bladder epithelial cells. Upon entry, the bacteria rapidly replicate and enter a complex developmental pathway ultimately forming intracellular bacterial communities (IBCs), a niche with biofilm-like properties protected from innate defences and antibiotics. Paradoxica...

Ten Gram-positive, aerobic bacterial strains with coccoid cells occurring singly, in pairs, tetrads and small aggregates were isolated from the surface of marble and calcareous stones. The peptidoglycan contained meso-diaminopimelic acid as the diagnostic diamino acid. The major menaquinone was MK-9(H4). The cellular fatty acid pattern consisted mainly of iso-branched chain components. Accordin...

Vibrio cholerae represents a significant threat to human health in developing countries. This pathogen forms biofilms which favors its attachment to surfaces and its survival and transmission by water or food. This work evaluated the in vitro biofilm formation of V. cholerae isolated from clinical and environmental sources on stainless steel of the type used in food processing by using the envi...

Five obligately anaerobic, Gram-stain-negative, saccharolytic and proteolytic, non-spore-forming bacilli (strains CD3 : 27, CD3 : 28(T), CD3 : 33, CD3 : 32 and CD3 : 34) are described. All five strains were isolated from the small intestine of a female child with coeliac disease. Cells of the five strains were short rods or coccoid cells with longer filamentous forms seen sporadically. The orga...

desired physical form of cities has been noticeable since the beginning of urbanization, from old patterns of early civilizations to the latest urbanism’s theories, which offered to build better cities. the opinions in recent decades have expressed that compact physical form of cities is a better form than sprawl form to achieve urban sustainability. the form of the city is the embodiment of it...

AIM To assess prospectively the value of three serological tests for differentiating between ulcerative colitis and Crohn's disease, used either alone or combined. METHODS Coded serum samples from 63 patients with ulcerative colitis and 67 patients with Crohn's disease were analysed. Detection assays for the presence of perinuclear antineutrophil cytoplasmic antibodies (pANCA), serum agglutin...
