Abstract
The occurrence and toxicity of Amphidinium carterae Hulburt is hereby reported for the first time from the North Arabian Sea on the coast of Pakistan. The concentrations of 1.2 Ã 104 cells mlâ1 were found in intertidal pools that were also inhabited by the brown macroalga Sargassum wightii. Both wild and cultured A. carterae cells were tested for ciguatera toxicity through exposure to brine shrimp nauplii (Artemia salina) and albino mice. Although the brine shrimp did not appear to be affected mortalities in mice ranged between 13 and 16% at doses of 7.2 Ã 104 and 2.5 Ã 105 cells mlâ1, respectively. When mice were affected pharmacological effects such as muscle contraction in lower back area, increased respiration, immobility and paralysis in hind limbs were observed for 2 h. These effects appeared to be reversible and gradually disappeared within 24 h.
