Host response toHelicobacter pyloriinfection before initiation of the adaptive immune response

The host immune response to Clostridium difficile.

Clostridium difficile is the most common cause of nosocomial bacterial diarrhoea in the Western world. Diarrhoea and colitis are caused by the actions of toxins A and B released by pathogenic strains of C. difficile. Adaptive immune responses to these toxins influence the outcomes of C. difficile infection (CDI). Symptomless carriers of toxinogenic C. difficile and those with a single episode o...

Host Immune Response to Intestinal Amebiasis

Entamoeba histolytica is an invasive enteric protozoan parasite that causes amebiasis. Globally, diarrheal disease is second only to pneumonia as a leading cause of death in children under five, and intestinal amebiasis is one of the top ten causes of severe diarrhea in the developing world. Amebiasis is more common in malnourished children, a state that afflicts approximately onethird of child...

Immune response and host-pathogen interactions.

For the most part, the relationship between the pathogen, Neisseria meningitidis, and humans is uneventful. Colonization of the human nasopharynx at various times during life is an almost universal experience but clinically overt disease is unusual except during epidemics. This overview considers the relationship between the meningococcus and humans, reviewing current immunological and molecula...

Host immune response against Scedosporium species.

Scedosporium apiospermum and Scedosporium prolificans cause therapy-refractory infections in immunocompromised and immunocompetent hosts. While innate immune response is believed to be critical for the host defense against these fungi, its role has only recently been elucidated. Undefined pathogen-associated molecular patterns on the surface of conidia and hyphae are recognized by pattern-recog...
