vannamei shrimp postlarvae indicated that toxins released from the cyanobacterial bloom from Chapultepec Lake were potentially capable of producing alteration and severity damage in antennal gland, gills, hepatopancreas, lymphoid organ, muscle and dorsal cecum caused killing of L.

Three of these crabs had moderate to high severity mikrocytid infections characterized by variable necrosis of the antennal gland and the presence of plasmodia and uninucleate forms of these parasites in the gills (not shown).
45% of these animals were affected by a mikrocytid parasite that initially infects the epithelial cells in the antennal gland and in high severity infections spreads to others tissue via the hemolymph.
Samples of hepatopancreas, heart, antennal gland, proximal intestine and abdominal muscle were collected and immediately placed on ice.
The hepatopancreas and antennal gland were sampled with sterile swabs (BBM CultureSwab Plus, Becton Dickinson, Basel, Switzerland) for culture on BA at 28[degrees]C for 48 h.
viridans was recovered from the hepatopancreas and antennal gland of all treatment group animals but no control group lobsters.
Briefly, dead and moribund lobsters from western LIS (zone 1) were collected from late October through early December 1999, and tissues including antenna, antennal gland, compound eye, hepatopancreas, gonad, stomach, intestine, gill, carapace and ventral nerve cord were fixed in 10% neutral buffered formalin, decalcified using Bouin's fixative and processed routinely for paraffin embedding.
Paramoebae were identified most often in antennae (11 of 13 lobsters), followed by eye (5 of 13), gill (3 of 13), ventral nerve cord (2 of 13) and antennal gland (1 of 13; Table 3).
