background : rhoptries are unique secretory/excretory organelles that are found exclusively in the apicomplexa, and their contents are discharged at the time of invasion and are critical in the establishment of productive infection. several rhoptry proteins have been identified in toxoplasma gondii , plasmodium falciparum and neospora caninum and have been linked not only with the parasites’ ad...

background: protein-protein interactions do not provide any direct information re­garding the domains within the proteins that mediate the interactions. the majority of proteins are multi domain proteins and the interaction between them is often defined by the pairs of their domains. most of the former studies focus only on interacting do­main pairs. however they do not consider the interaction...

background: nontypeable haemophilus influenzae (nthi) is a common cause of respiratory tract disease and initiates infection by colonization in nasopharynx. the haemophilus influenzae (h. influenzae) hap adhesin is an auto transporter protein that promotes initial interaction with human epithelial cells. hap protein contains a 110 kda internal passenger domain called “haps” and a 45 kda c-termi...

host innate immunity can affect the clinical outcomes of helicobacter pylori infection, including gastritis, gastric ulcer, gastric adenocarcinoma, and malt lymphoma. nucleotide binding oligomerization domain (nod)-1 and -2 are two molecules of innate immunity which are involved in the host defense against h. pylori . this study aimed to evaluate the effect of the expression level of nod1 and n...

introduction: acinetobacter baumannii is associated with hospital-acquired infections. outer membrane protein a of a.baumannii (abompa) is a well-characterized virulence factor which has important roles in pathogenesis of this bacterium. methods: based on our pcr-sequencing of ompa gene in the clinical isolates, abompa protein can be categorized into two types, named here type-1 and type-2. we ...
