D'ávila, S., Manso, P. P. A., Bessa, E. C. A., Rodrigues, M. L. A. and Dias, R. J. P. 2010. Gross anatomy of the musculature and a new description of the reproductive system of Tanaisia bragai and Tanaisia inopina (Trematoda: Eucotylidae) analysed by confocal laser scanning microscopy. -Acta Zoologica (Stockholm) 91: 139-149Confocal scanning laser microscopy has become an important tool to clarify the organization of the musculature and innervation, as well as the morphology of the reproductive and alimentary tract of various helminth species. The goal of this work was to describe the morphology of the reproductive system and the gross anatomy of the musculature of adults of the species Tanaisia bragai and Tanaisia inopina by means of confocal scanning laser microscopy. The helminths were found parasitizing the kidney collection ducts of Columba livia, in the municipality of Juiz de Fora, Brazil. These helminths were stained with Mayer's carmalum, mounted on permanent slides and observed through a confocal scanning laser microscope. The tomographic images showed the morphology of the organs and glands of the reproductive system, along with the general morphology of the musculature of the body wall, oral sucker, acetabulum, pharynx, intestinal caeca, oesophagus and reproductive system ducts. The present work is the first re-characterization of the reproductive tract of T. bragai and T. inopina. We also present the first description of the general morphology of the gametes and cells of the glands associated with the reproductive apparatus of these species.

“…Tanaisia inopina was described by from specimens recovered from Passer domesticus, previously identified by Almeida (1936) as T. zarudinyi. Later, Sterna sp., Icterus chrysocephalus and Coturnix japonica were registered as new hosts for this species by Freitas (1959), Franco (1965) and Pinto et al (2005), respectively.…”

The objective of the present study was to describe the composition and structure of the helminth community present in domestic pigeons, in the municipality of Juiz de Fora, Minas Gerais, Brazil. The helminthological survey of 35 hosts revealed the presence of two digenetic trematodes, Tanaisia (Paratanaisia) bragai (prevalence 51.42%, mean intensity 288.8 ± 403.86 and mean abundance 148 ± 320.9) and T. inopina (prevalence 2.85% and mean abundance 0.68 ± 4.05); five cestodes, Raillietina allomyodes (prevalence 34.28%, mean intensity 6.66 ± 9.14 and mean abundance 2.28 ± 6.11), Raillietina sp. (prevalence 37.14%, mean intensity 9 ± 10.68 and mean abundance 3.34 ± 7.7), Skrjabinia bonini (prevalence 20%, mean intensity 2.14 ± 1.21 and mean abundance 0.42 ± 1), Skrjabinia sp.( prevalence 5.7%, mean intensity 6 ± 7 and mean abundance 0.34 ± 7) and Fuhrmanneta sp. (prevalence 2.85% and mean abundance 0.028 ± 0.16) and four nematodes, Baruscapillaria obsignata (prevalence 51.42%, mean intensity 29.72 ± 44.2 and mean abundance 15.28 ± 34.7); Ascaridia columbae (prevalence 51.42%, mean intensity 60.55 ± 79.88 and mean abundance 31.14 ± 64.2); Tetrameres fissipina (prevalence 14.28%, mean intensity 346.3 ± 504.4 and mean abundance 49.42 ± 212.1) and Synhimanthus (Dyspharynx) nasuta (prevalence 2.85% and mean abundance 0.028 ± 0.16). Among the examined hosts, 97.2 % were found parasitized by at least one helminth species. In accordance with the prevalence of each species T. bragai, A. columbae and B. obsignata were considered secondary species and T. inopina, T. fissipina, S. nasuta, S. bonini, Skrjabinia sp., R. allomyodes, Raillietina sp. and Fuhrmanneta sp. were considered satellite species. All the species exhibited aggregate distributions, which is the most common distribution pattern in helminth populations.

“…In Brazil, studies concerning this trematode have focused on taxonomy, life cycle, pathology in the definitive host, occurrence and prevalence. Tanaisia bragai was reported infecting Columba livia Gmelin, 1789; Gallus gallus domesticus (Linnaeus, 1758); Odontophorus capueira Cory, 1915; Meleagris gallopavo Linnaeus, 1758 and Columbina talpacoti Temmink, 1810 (Santos, 1934;Pinto et al 2004;Franco 1965) Keller and Araújo (1992) studied the life cycle of T. bragai, under laboratory conditions, infecting the land snail Leptinaria unilamellata (d'Orbigny, 1835), and Brandolini et al (1997) carried out experimental infection of Subulina octona (Bruguière, 1789), the intermediate host first reported by Maldonado (1945). Portugal et al (1972), as well as Pinto et al (2004), described the pathology caused by T. bragai in C. livia and C. talpacoti, respectively.…”

The aim of this study was to obtain data on the morphology and morphometry of pre-ovigerous and post-ovigerous adults of the species Tanaisia (Paratanaisia) bragai, using confocal laser scanning microscopy to obtain tomographic images of the suckers and tegument. For morphometric analysis, 45 specimens (30 pre-ovigerous adults and 15 post-ovigerous adults) were measured with the aid of an ocular micrometer coupled to the objective of a photonic microscope. Pre-ovigerous and post-ovigerous adult individuals, stained with Mair carmalumen and mounted in permanent preparations, were analyzed by means of confocal laser scanning microscopy. Positive correlation was detected between the body length and ovary length of post-ovigerous adults (rs: 0.774; p<0.01), as well as between the body length and testes (rs: 0.604 and 0.659; p< 0.05), the body length and the length of uterus (rs: 0.839; p< 0,01) and between the ovary width and egg length (rs: 0.777; p<0.01). Morphological study of the pre-ovigerous adults demonstrated that the ovary and testes develop simultaneously before the development of the uterus and vitelline glands. The acetabulum was detected in pre-ovigerous adults stained with hematoxilin and observed using light microscopy. In these specimens, the acetabulum measured 36.7 ± 6.9 µm (25-50 µm) in width and 39.91 ± 6.8 µm (25-55 µm) in length. The acetabulum was not detected in post-ovigerous adults observed with light microscopy. However, this structure was detected using confocal miscrocopy. In the post-ovigerous specimens, the acetabulum presented a reduced size compared to the pre-ovigerous adults. This may imply that this structure has more functional significance in the larval and pre-ovigerous stages.
