Crustacean-acanthocephalan interaction and host cell-mediated immunity: parasite encapsulation and melanization

Crustacean-acanthocephalan interaction and host cell-mediated immunity: parasite encapsulation and melanization.

Host-parasite interactions of Pomphorhynchus laevis (Müller, 1776) in naturally infected amphipod, Echinogammarus stammeri (Karaman), from the Brenta River (northern Italy) are described. A fully developed acanthocephalan larva occupies a large portion of an amphipod's haemocoelic space; thus, the parasite frequently induces displacement of host digestive tract and other internal organs. Howeve...

Host-parasite interactions and immunity to irradiated sporozoites.

We compare and contrast the results of immunizing mice with irradiated sporozoites of Plasmodium berghei and Plasmodium yoelii. Host genetic control of protective immunity is different in the two rodent malarias. Few mouse strains are strongly protected by P. yoelii sporozoites, while all are protected by P. berghei sporozoite immunization. The role of CD8+ T cells in the protective immune resp...

EVALUATION OF CELL-MEDIATED IMMUNITY IN MUSTARD GAS INJURIES

Yamakido, et al. in 1986 have studied immunological parameters in poison gas workers, and a depression has been observed in immunologic response. Also, the frequency of cancer has reached as high as five-fold that of the general population. In the present study, cell-mediated immunity (CMI) was measured in three groups of Iranian mustard gas-injured patients. The first group were those wh...

Trichomonas vaginalis and Tritrichomonas foetus: interaction with fibroblasts and muscle cells - new insights into parasite-mediated host cell cytotoxicity.

Trichomonas vaginalis and Tritrichomonas foetus are parasitic, flagellated protists that inhabit the urogenital tract of humans and bovines, respectively. T. vaginalis causes the most prevalent non-viral sexually transmitted disease worldwide and has been associated with an increased risk for human immunodeficiency virus-1 infection in humans. Infections by T. foetus cause significant losses to...
