Abstract: The present work morphologically characterizes Paratrichodina africana from the gills of wild and farmed Nile tilapia from Northern Brazil (eastern Amazonia). Ninety fish were captured for parasitological analysis in Macapá, State of Amapá, from a wetland area bathed by the Amazon River commonly called 'Ressaca do Zerão' (n = 52), as well as from a local fish farm (n = 38). Wet smears of the skin and gills of the captured fish were air dried at room temperature and impregnated with silver nitrate by Klein's me… Show more

“…The denticle shape of T. corydori mostly resembles Paratrichodina africana Kazubski and El-Tantawy, 1986 recently reported from wild and farmed Oreochromis niloticus (Linnaeus) in eastern Amazonia, Brazil by Tavares-Dias et al (2013). However, T. corydori differs from P. africana in the shape of the denticle, some other measurements, as well as the adoral spiral: (1) The new species is larger than P. africana, for example, in the adhesive disc (27.7-37.0 vs. 12.2-25), and denticulate ring (16.2-23.3 vs. 5.7-16.5).…”

“…The trichodinid species identified in this study (T. centrostrigeata, T. compacta, T. heterodentata, T. migala, T. orthodens, P. africana) have mainly been observed as parasites of cichlids in African and Asian countries (Duncan, 1977;Basson et al, 1983;Kazubski and El-Tantawy, 1986;Van As and Basson, 1989;Van As and Basson, 1992). In Brazil, only T. centrostrigeata (Bittencourt et al, 2014), T. compacta (Ghiraldelli et al, 2006;Jerônimo et al, 2011;Zago et al, 2014), T. magna (Martins and Ghiraldelli, 2008;Zago et al, 2014), Trichodina nobilis Chen, 1963 (Bittencourt et al, 2014) and P. africana (Pantoja et al, 2012;Tavares-Dias et al, 2013;Valladão et al, 2013;Bittencourt et al, 2014) had previously been described as affecting Nile tilapia.…”

“…Some studies suggest that parasites are also vectors of other pathogens, which can lead to acute mortality of fish (Xu et al, 2012;Pilloux et al, 2015). Ectoparasites are common in tilapia culture and have been reported by several authors (Ghiraldelli et al, 2006a;Jerônimo et al, 2011;Tavares-Dias et al, 2013;Nunes et al, 2016) and according to Moraes & Martins (2004) are directly related to water quality and animal management.…”
