Gill tissue reactions in walleye Stizostedion Vitreum vitreum and common carp Cyprinus carpio to glochidia of the freshwater mussel Lampsilis radiata siliquoidea

Mast cells/eosinophilic granule cells of teleostean fish: a review focusing on staining properties and functional responses

“…Responses similar to those of salmonids, with local recruitment/accumulation of MCs/EGCs in parasiteinfected tissues have been demonstrated in catostomids (Chaicharn & MAST CELLS/EOSINOPHILIC GRANULE CELLS Bullock, 1967;Lester & Daniels, 1976), cyprinids (Percy, 1970Cross & Matthews, 1993 and labroids (Reimschuessel et al, 1987;Reite, 1996b). Thus, recruitment of MCs/EGCs to sites of persistent inflammation seems to be a general response in teleosts, and it should also be mentioned that fewer EGCs have been found in tissues surrounding freshwater mussel glochidia in unsuitable than in suitable hosts (Fustish & Millemann, 1978;Waller & Mitchell, 1989). The numerous eosinophils described to appear locally during inflammation and wound healing in the skin of the stickleback, Gasterosteus aculeatus (Phromsuthirak, 1977) and in inflammatory exudates in the peritoneal cavity of the striped bass, Morone saxatilis (Bodammer, 1986) and tilapia, Oreochromis nilotica (Suzuki, K., 1986) may also have been tissue EGCs, as may the ' eosinophils with coarse granules ' demonstrated by an early investigator (Drury, 1915) in the peritoneal fluid of several teleostean species.…”

Persistence of host response against glochidia larvae in Micropterus salmoides

Experimentally Induced Glochidiosis in Smallmouth Bass (Micropterus dolomieu)

“…Similar differences in encapsulation and gill tissue reactions and length of infection have been seen with Lampsilis radiata siliquoidea infections in walleye (Stizostedion vitreum vitreum), a suitable host, versus common carp (Cyprinus carpio), a resistant host. 12 Although most natural infections of glochidia go undetected, this report demonstrates the potential for lethal glochidia infections. Introduction of the zebra mussel, an aggressive, nonglochidia-forming species, demonstrates the potential for introduction of glochidia-producing mussels that might out compete and replace native mussel species.…”
