The increased resistance of campylobacters to antibiotics required the identification and isolation novel antimicrobials able inhibit its virulence, cause less or no display host toxicity. Acquiring all this knowledge was only possible through a better understanding their antibacterial potency biological mechanisms involved attenuating bacterial virulence factors. This review describes most rec...

conclusions these findings underscored the importance of monitoring and developing guidelines for better management of infectious diarrhoea in bangladesh and elsewhere. background diarrhoea is considered as the most widespread illness occurring in bangladesh. in addition, the growing antimicrobial resistance of diarrhoeal pathogens in this developing country hardens physicians to supervise pati...

The aim of this study was to isolate and identify airborne fungi from locations in Babol city, Babolkenar forest and a beach on the Caspian Sea (all in North part of Iran) in spring and summer. Of 126 samples collected, the most clinically important isolated fungi were Mucor spp. (18.6%) in the forest, Alternaria spp. (13.4%) at the beach; and Cladophialophora spp. (15.8%), Mucor spp. (11.7%) a...

background: blastocystis  is a zoonotic protozoan parasite habit in intestinal tract of humans and wide range of animals. because of the mysterious nature and unknown or less-known aspects of blastocystis, comprehensive information about epidemiology of this parasite is not available. the objective of this study was to investigate the available parasitology studies during the last decade in ira...

A field program to control multiple anthelmintic resistant worm infections in cattle of Argentina is described. In 2003 around 140 calves died as a consequence of high worm burdens despite the administration of monthly alternate treatments with ivermectin (IVM) or fenbendazole (FBZ). A fecal egg count reduction test (FECRT) showed a clinical efficacy of 73%, 49.1% and 90.4% for IVM, FBZ and lev...

Streptococcus sanguis on media containing 3% sucrose gives rise to characteristic hard cohesive colonies (designated Spp+). Populations of Spp+ bacteria (strain Challis) on sucrose media switch to a soft noncohesive phenotype (designated Spp-) at a frequency of 10(-4) to 10(-3). Spp- bacteria switch back to Spp+ bacteria at a similar frequency. Successive rounds of Spp variation were observed. ...

Exogenous sphingosine-1-phosphate (SPP) inhibits chemotactic motility of several transformed cell lines. We have found that SPP at high micromolar concentrations decreased chemotaxis of estrogen-independent (MDA-MB-231 and BT 549) and estrogen-dependent (MCF-7 and ZR-75-1) human breast cancer cells. Because SPP has been implicated as a lipid-signaling molecule with novel dual intra- and interce...

Physiological features were examined of a 20-year-old Vitis vinifera ‘Italia’ table grape vineyard cropped in Apulia, Italy. Healthy vines with no foliar symptoms and any indications wood or berry alterations, natural infections by Phaeoacremonium minimum (syn. P. aleophilum) Phaeomoniella chlamydospora showing brown streaking symptoms, naturally infected minimum, Fomitiporia mediterranea white...

We identified the Drosophila melanogaster Signal peptide peptidase gene (Spp) that encodes a multipass transmembrane aspartyl protease. Drosophila SPP is homologous to the human signal peptide peptidase (SPP) and is distantly related to the presenilins. We show that, like human SPP, Drosophila SPP can proteolyze a model signal peptide and is sensitive to an SPP protease inhibitor and that it lo...
