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...

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...

ABSTRACT Ascocarps of Phaeosphaeria nodorum, which causes Stagonospora nodorum blotch (SNB) of wheat, have not been found by others in the eastern United States despite extensive searches. We sampled tissues from living wheat plants or wheat debris in Kinston, NC, each month except June from May to October 2003. Additional wheat samples were gathered in Kinston, Salisbury, and Plymouth, NC, in ...

Endophytic and epiphytic bacteria fungi that live in association with macroalgae produce compounds favor the growth of host, being some cases more efficient than those produced by terrestrial microbiome. This review collects information from articles published Scopus, ScienceDirect, PubMed, Wiley Online Library. Articles were organized according to their antimicrobial properties, synthesis hydr...
