Helminth infracommunities of gallotia caesaris caesaris and gallotia caesaris gomerae (sauria: lacertidae) from the Canary islands (eastern Atlantic)
A survey of gastrointestinal helminth communities of Gallotia caesaris caesaris (Lehrs, 1914) and G. c. gomerae (Boettger and Müller, 1914), from the islands of El Hierro and La Gomera, respectively, in the Canary Archipelago, Spain, was conducted to determine the prevalence, intensity, and diversity of intestinal parasites of these lacertid lizards. Larval forms of cestodes, nematodes, and acanthocephalans were found in the body cavity of G. c. caesaris; this lizard is the intermediate or paratenic host in the life cycle of these helminths. Pharyngodonid nematodes were the most common intestinal helminths in both hosts, 4 of them being Gallotia spp. specialists. Helminth infracommunities o…
El tamaño importa: tractos digestivos y nematodos Pharyngodonidae parásitos de reptiles.
En conclusión podemos afirmar que el notable tamaño del colon de los lagartos canarios resulta un microhábitat adecuado para albergar amplias faunas de nematodos oxiúridos de manera similar a lo que se observa en iguánidos y tortugas terrestres.
Helminths of some lizards of the Iberian Peninsula: bioindicators of the ecology of their hosts.
Parasitological studies carried out for more than three decades have been compared in twelve of the species of lizards that inhabit Iberian Peninsula. The species studied exhibit different ecological strategies in distinct aspects of their way of life. The working hypothesis is that these different ecological characteristics of these hosts will condition the quality and quantity of their helminth communities. Several parameters of host helminth faunas have been compared, such as prevalence, intensity and abundance of infection, and Brillouin diversity index in order to establish similarities and differences between the parasitic communities of the different hosts. Indeed, there are notable …
