    Aggregata (Protozoa: Apicomplexa) infection in the common octopus Octopus vulgaris from the West Mediterranean Sea: The infection rates and possible effect of faunistic,environmental and ecological factors
    (Elsevier, 2013-04-13) Mayo-Hernández, E.; Barcala, E.; Berriatua, E.; Muñoz, P.; García Ayala, Alfonsa; Sanidad Animal
    Prevalence and distribution of the coccidian parasite Aggregata octopiana (Protozoa: Apicomplexa) in common octopus (Octopus vulgaris) in the Mediterranean Spanish coasts were studied. A total of 114 octopuses were sampled from 30 geographic sectors by trawlfleet, and whitish macroscopic oocysts typical of A. octopiana infection were recorded in 96% of octopuses in the digestive tract and mainly in intestine and spiral caecum. The univariate analysis showed that lesion extension varied according to specific octopus, environmental and faunis- tic variables. A subsequent multivariable analysis indicated that the risk of macroscopic lesions in the caecum was greater in males compared to females, in octopuses living in deeper compared to shallower waters and in hauls where the crustacean.Pagurus excavatus was present. The study provides further evidence of the abundance of A. octopianain octopus ecosystems urging for further studies to evaluate its health impact. The combined abundance of infected octopuses and P. excavatus merits attention.

    Records of Eimeria spp. and their patterns of excretion in captive North African Gazelles
    (Helminthological Society of Washington, 2001) Ruiz de Ybáñez Carnero, María del Rocío; Ortiz, Juana; Garijo Toledo, María Magdalena; Espeso, Gerardo; Abaigar, Teresa; Cano, Mar; Sanidad Animal
    The species of Eimeria occurring in 3 species of captive gazelles (Gazella dama mhorr, Gazella cuvieri, and Gazella dorcas neglecta) were identified. This is the first report of Eimeria pallida, Eimeria elegans, and Eimeria gazella in these hosts and also the first report of E. elegans and E. gazella in Spain. Feces were collected from each of 9 young gazelles for periods of 3-7 mo to determine their oocyst shedding profile. Most oocysts appeared at 20-25 d, peaked, and decreased to undetectable levels between 40 and 115 d. Eimeria gazella delayed its excretion, which continued at low levels throughout the observation stage. No clinical signs of infection were observed in the gazelles during the study.
