Tapeworm larvae in Artemia franciscana (Crustacea: Anostraca) in the Godolphin lakes of Dubai (United Arab Emirates) throughout an annual cycle.

ABSTRACT

A total of 1840 brine shrimps (Artemia franciscana) were examined for cestode larvae at monthly intervals between November 2015 and June 2016. Of these, 663 (36.03%) specimens were infected with cysticercoids of seven cestode species in numbers between one and sixteen. During the first four months of examination, the percentage of infected shrimps was low but rose significantly with increasing temperatures in March, reaching maximum values in May. Flamingolepis liguloides and Flamingolepis flamingo showed the highest prevalence overall, at 25.3 and 10.7%, respectively. The intensity of infection was 1-10 and 1-4 cysticercoids, respectively. Eurycestus avoceti, Wardium stellorae, Gynandrotaenia stammeri, Anomotaenia tringae and Confluaria podicipina occurred at lower prevalence of 4.5, 3.2, 1.7, 0.3 and 0.05%, respectively. Up to four species were detected in one host.
