Host immune response againstScedosporiumspecies

Bacterial antigenic variation, host immune response, and pathogen-host coevolution.

Many bacterial pathogens are exquisitely adapted to host parasitization. Their niche is primarily determined by the biochemical milieu of the host. As such, pathogens are selected to exhibit environmentally responsive and adaptive molecular traits which allow adherence, entrance, and replication within the host (7, 26). One major set of selective forces which operates to shape the phenotype of ...

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...
