“…De Chambrier and Vaucher (1999) have demonstrated the presence of vitelline follicles in T. avitellina, contrary to the observations of Rego and Pavanelli (1987, p. 358 and 359) and Rego (1994, p. 261). Moreover, the absence of vitelline follicles was the main criterion that led Rego Travassiella avitellina Rego & Pavanelli, 1987. Pavanelli (1987) to propose the genus Travassiella.…”

“…Lately, Rego et al (1999) observed vitelline follicles in gravid proglottides. However, the vitelline follicles are in the cortex of the proglottis and therefore the genus has been placed in the Zygobothriinae by de Chambrier and Vaucher (1999).…”

“…Rego and Pavanelli (1987) included Travassiella in the Proteocephalinae Mola, 1929 based on the medullar condition of the genitalia, and the absence of vitelline follicles. De Chambrier and Vaucher (1999) observed the presence of vitelline follicles in the cortex of the proglottis in T. avitellina and transferred this species to Zygobothriinae Woodland, 1933, within Monticelliidae.…”

“…In contrast to the present study, Moravec et al (2002) did not observe seasonal variation. A 100% prevalence in C. piquiti was also reported in fish parasitized by Proteocephalus chamelensis (Pérez Ponce de Leó n et al, 1995) and by S. maringaensis (De Chambrier & Vaucher, 1999;Arredondo & Gil de Pertierra, 2008). According to Scholz (1987), larger perch were the most parasitized by Proteocephalus percae Mü ller, 1780.…”

Infection levels of proteocephalidean cestodes inCichla piquiti(Osteichthyes: Cichlidae) of the Volta Grande Reservoir, Minas Gerais, Brazil, relative to host body weight and gender

We evaluated the relationship between infection by proteocephalid cestodes and the sex and weight classes of tucunaré (Cichla piquiti) captured between August 1999 and June 2001 in the Volta Grande Reservoir, Minas Gerais, Brazil. A total of 96 fish, 75.9^9.3% males and 88.9^6.4% females, were parasitized by Proteocephalus macrophallus and P. microscopicus, with total mean intensities of 76.6^23.9 and 145.2^36.7, respectively, during this period. In the majority of the months analysed, males showed 71.4 -100% prevalence of parasitism and females 80 -100%. Although there was no significant difference, females showed a higher mean intensity of infection (145.2^36.7) than males (76.6^23.9). Fish weighing 300 -800 g showed a higher mean abundance of parasites (P , 0.05) compared with the biggest specimens weighing 801 -2750 g. Analysing both males and females together, the greatest mean intensities of infection were found in October and December (P , 0.05) independent of the year, which coincides with the months of highest rainfall. These results show that fish living in reservoirs may be more susceptible to intermediate hosts than those that live in rivers.

The fine structure of the mature spermatozoon of the proteocephalidean tapeworm Proteocephalus torulosus, a parasite of cyprinid fishes, was studied by transmission electron microscopy for the first time. The mature spermatozoon of P. torulosus is filiform and tapered at both extremities. It contains two axonemes of the 9+''1'' type and of unequal length. The anterior extremity of the spermatozoon bears a helicoidal crested body approximately 100 nm thick. Cortical microtubules of two types lie parallel to the spermatozoon axis. The nucleus is a fine cord of condensed chromatin. The slightly electron-dense cytoplasm contains electrondense granules in regions II and III of the spermatozoon. The anterior and posterior extremities of the spermatozoon contain a single axoneme. The mature spermatozoon of P. torulosus differs from that of other Proteocephalus species in the presence of a single crested body and in the morphology of its posterior end.
