“…Infection with Sebekia oxycephala may be related to the semiaquatic habit and piscivorous diet of this host, since the nymphs of Sebekia species use fishes with intermediate hosts (Junker et al, 1998;Almeida et al, 2010;Santos-Costa et al, 2022), suggesting the use of Helicops angulatus as a second intermediate host in the life cycle of this parasite. The Sebekia species has already been registered infecting other species of Helicops, such as H. leopardinus (Schlegel, 1837) in Pantanal, state of Mato Grosso (Rego & Vicente, 1988) and H. infrataeniatus (Jan, 1865) in the state de São Paulo (Silva et al, 2015). In addition, there are is a water snake, widely distributed in Brazil (Uetz et al, 2023).…”

In this study, we investigated the infection by pulmonary parasites in the water snake Helicops angulatus. We found four nymphs of the pentastomide parasite Sebekia oxycephala, parasitizing two adult females H. angulatus collected in the municipality of Rio Tinto, Paraíba, Brazil. This occurrence is likely due to the nymphs of this parasite directly infecting aquatic intermediate hosts, such as fish. The result of this study represents the first record of pentastomid infecting H. angulatus.

Pygocentrus piraya is an endemic species of the São Francisco River basin. In this study, 342 carnivorous fish were examined, nymphs specimens of Sebekia sp. and its ecological indexes are recorded only in piranhas, of the total of 53 collected from three marginal lagoons of the middle São Francisco River basin: 17 specimens from Curral de Varas lagoon; 15 from Maris lagoon, both of state of Minas Gerais; and 21 specimens from Mocambo lagoon, state of Bahia. The prevalence (P) and mean abundance (MA) of Sebekia sp. nymphs in intermediate hosts were as follows: in Curral de Varas lagoon, P = 11.8%, MA = 0.18; in Maris lagoon, P = 46.6%, MA = 0.47; and in Mocambo lagoon, P = 14.3%, MA = 1.05. Despite the lower number of fish examined from Maris lagoon, this lagoon had the highest number of piranhas (seven) parasitized by Sebekia sp. Pentastomids have zoonotic importance and evaluation of the indirect life cycle of sebekids in lagoons is necessary for defining the intermediate and final hosts involved. This record is novel and stems from collection of piranhas in the marginal lagoons of the São Francisco River, in the states of Minas Gerais and Bahia, Brazil.

“…Platyhelminthes (trematodes, cestodes), hirudineans and acanthocephalans were stained with Carmine as described by Vidal-Martínez et al (2001). Nematodes and pentastomids were cleared in graded solutions of glycerine-water (Moravec et al, 1995;Silva et al, 2015). Infection parameters, such as prevalence, mean abundance and mean intensity were those proposed by Bush et al (1997), whereas parasite species were classified as autogenic (i.e., mature in fishes or other aquatic hosts, are incapable of crossing land barriers between freshwater bodies) and allogenic (i.e., mature in mammal or bird hosts and use fish only as intermediate and paratenic host) (Esch et al, 1988;Salgado-Maldonado et al, 2016).…”

Metazoan parasite communities of three endemic cichlid fish species from the upper Grijalva River, Chiapas, Mexico

et al. 2020

SummaryWe recorded the metazoan parasite communities in three endemic cichlids (Chiapaheros grammodes, Vieja breidohri and V. hartwegi) collected between November 2008 and July 2009 in the upper Grijalva River Basin (GRB), Chiapas, Mexico. In total, 6,287 individual parasites belonging to 18 taxa (1 monogenean, 6 digeneans, 1 cestode, 4 nematodes, 2 acanthocephalans, 1 hirudinean, 2 copepods and 1 pentastomid) were found. Eleven metazoans were adult forms and 7 larvae; moreover, 14 were endoparasites and 4 ectoparasites. Sixteen parasite taxa represent new geographical and host records. The helminth community in the three cichlids was characterized by higher number of generalists than specialists, as well as a higher proportion of autogenics than allogenics. The metazoan parasites showed prevalence and mean abundances moderate to high. The infracommunities and component community of metazoan parasites had low diversity, richness, and number of individuals and are similar to those reported for other cichlids in Southeastern Mexico, characterized by the presence of typical parasites of cichlids, with a high number of digeneans and generalist parasites. We report the introduced Asian parasitic copepod Neoergasilus japonicus parasitizing endangered or threatened endemic cichlids in the upper GRB. This copepod have been widespread in other freshwater fish species, mainly in Asia (China, India, Japan, Russia, Taiwan), Europe (France, Hungary, Italy, Turkey), and America (Cuba, Mexico, Peru, United States).
