Cryptosporidium pathogenicity and virulence.
Cryptosporidium is a protozoan parasite of medical and veterinary importance that causes gastroenteritis in a variety of vertebrate hosts. Several studies have reported different degrees of pathogenicity and virulence among Cryptosporidium species and isolates of the same species as well as evidence of variation in host susceptibility to infection. The identification and validation of Cryptospo...
متن کاملPathogenicity and haemagglutinin gene sequence analysis of Iranian avian influenza H9N2 viruses isolated during (1998–2001)
Sixteen avian influenza (AI) H9N2 viruses were isolated from disease outbreaks in different parts of Iranduring (1998–2001). These AI isolates were used for pathogenicity, haemagglutinin (HA) gene variation andphylogenetic analysis. Results in both pathogenicity tests and HA gene cleavage site sequence detectionrepresented a non-highly pathogenic feature for all Iranian AI isolates studied. The...
متن کاملPrevalence of adhesion Virulence factor genes, antibiogram, and pathogenicity of avian Pasteurella multocida isolate from Iran
Pasteurella multocida possesses various virulence factors, including capsule, lipopolysaccharide, fimbriae, toxins, outer membrane proteins, and adhesions. Adhesins have a crucial role in mediating colonization and invasion of the host. The aim of the present study was to identify the prevalence of adhesion factor genes and resistance/sensitivity patterns among the avian P. multocida isolates f...
متن کاملEnterococcal virulence--pathogenicity island of E. Faecalis.
Enterococcal species, though most commonly regarded as members of the microbial flora of the intestinal tract, have recently emerged as human pathogens of significant concern. The rapid spread of antibiotic resistance among enterococci, which has resulted in strains now being routinely isolated that are resistant to all bactericidal regimens, has prompted considerable interest in investigating ...

It is now known that uropathogenic E. coli contains at least four PAIs inserted into various tRNA sites, countries, this may be only a technicality. ranging in size from 40 kb to 190 kb, encoding diverse Another book with the same title was published in virulence factors such as fimbriae, iron utilization, and 1998, edited by Willi...
