The Difference

An investigation of the digenetic trematodes of anurans from Agbede, a location in the derived savanna biotope in Edo state,Nigeria was conducted from August, 2007 to July, 2008. Anuran hosts examined included Sclerophrys maculata, S.regularis, Ptychadena pumilio, P. bibroni, P. oxyrhynchus, Hoplobatrachus occipitalis and Hylarana galamensis. Theanurans were collected using the Visual Acoustic Encounter Survey (VAES) method, dissected and examined for trematodeinfections. A total of 267 anurans were examined of which 33 were infected with an overall prevalence of 12.36%. Seasonalprevalence was 14.88% for the wet season and 8.08% for dry season. The difference in prevalence values was not statisticallysignificant (p >0.05). Four digenetic trematodes, namely, Mesocoelium monodi, an unidentified Mesocoelium sp.,Haematoloechus exoterorchis and an unidentified Haematoloechus sp. Haematoloechus exoterorchis was recovered from H.occipitalis while the unidentified Haematoloechus sp. infected H. occipitalis and Sclerophrys maculata. Mesocoeliummonodi infected only Sclerophrys maculata while the unidentified Mesocoelium sp. was a generalist, infecting five anuranhosts. Sclerophrys maculata is thus a new host record for the genus Haematoloechus in Nigeria. In conclusion, this studyrevealed a low trematode diversity in the anurans of the savanna-mosaic at Agbede. However, anurans from this locationharboured two new trematodes: an unidentified Mesocoelium sp and a Haematolechus sp. Sclerophrys maculata as a newhost record for the genus Haematoloechus in Nigeria. More specimens of the Haematoloechus sp. are needed for themorphological description and molecular characterization of the parasite, to establish its relationship with the cogener inH.occipitalis.

Abstract Morphological Redescription and Molecular Characterization of Dactylogyrus labei (Monogenea, Dactylogyridae) from Catla catla: a New Host Record in India. Chiary, H. R., Chaudhary, A., Singh, H. S. - Dactylogyrus labei Musselius et Gusev, 1976 (atypical form) specimens were collected from host Catla catla from the river Brahmaputra, Guwahati, Assam, India. The Dactylogyrus samples were examined by morphological and molecular methods. This parasite was originally described from Labeo rohita from fish farm Kalyani, West Bengal, India, but the morphological study of sclerotized parts showed the existence of D. labei on Catla catla. This is the first record of D. labei from Catla catla in India.

The present study provides a new insight into valuable information on the diverse structure of the Anisakid population and discusses the limited species richness in the Nemipterus japonicus (Bloch,1791) (Perciformes, Nemiperidae). The fishing area consists of various locations in the Arabian Gulf (29°58 0 33 00 N48°28 0 20 E). A total of 315 marine fish were examined, (n=287) were infected. Larval stages (n= 763) encysted within the mesenteries peritoneum and viscera of fish organs were isolated, with a prevalence of 91.11% of infection and, the intensity was 2.65. Molecular analysis was carried out on thirty individuals who have examined the morphology and showed some appearance differences, by amplifying internal transcribed spacers ITS and ITS-1 of nuclear rDNA (rDNA) by PCR using the primer sets NC5/NC2 and SS1/NC13R of thirteen DNA products. Evolutionary analyses were conducted in MEGA X. based on the identity percentage in the GenBank database showed that they belong to anisakid nematodes, in particular, they belong to eleven distinct taxa within the Hysterothylacium Ward & Magath, 1917 (Rhabditida, Raphidascarididae) and one identified species H. amoyense (Hsü, 1933) Deardorff & Overstreet, 1980. The current study records eleven species that belong to a genus of Hysterothylacium; some of the alignment of sequences polymorphisms reveals new different individuals of larvae species that may be adopted as new species if their adult stage is detected, and N. japonicus fish considered as a new host record. The current study provides some insights on the systematic taxonomy of these parasites, in addition, it supports similar studies that have been published elsewhere.

A novel species, Micropeltis goniothalamicola and a new record Scolecopeltidium menglaense were collected from Mae Fah Luang Botanical Gardens, Thailand. Our new taxon is different from other species in Micropeltis in having relatively smaller ascomata, 6–8-spored asci and 4–5-septate ascospores covering with mucilaginous sheath. Our new record, S. menglaense is the first host recorded from Jasmine grandiflorum (Oleaceae). Morphological comparison coupled with phylogenetic analysis of combined LSU and ITS sequence data provide evidence for the new species and new host record.

Rhipidocotyle pentagonum (Ozaki, 1924) is reported for the first time in South America parasitizing Auxis thazard and in a new host Katsuwonus pelamis. Tergestia laticollis (Rudolphi, 1819) is reported for the first time in South America and in Thunnus albacares, representing a new host record. Copiatestes filiferus (Leuckart, in Sars, 1885) is recorded for the first time in Brazil and in Thunnus albacares, another new host record. Tetrochetus coryphaenae (Yamaguti, 1934) is presented for the first time in Brazil parasitizing Thunnus albacares.
