Box 1346 Ann Arbor, Ml 48106- 1346 ABSTRACT Shistes c m c a In Africa the schistosomes that belong to the haematobium group are transmitted in a highly species specific manner by snails of the genus Bulinus. Hence the miracidial larvae of a given schistosome will develop in a compatible snail but upe*\. ^entering an incompatible snail an immune response will be elicited which destroys the trematode. 4 The factors governing such interactions were investigated using the following host/parasite combination? Bulinus natalensis and B^_ nasutus with the parasite Spect'e3 marqrebowiei. This schistosome^develops in B^_ natalensis but not in B_;_ nasutus. The immune defence system of snails consists of cells (haemocytes) and haemolymph factors. -

Jonathan Department of Plant Science and Applied Zoology, Parasitology and Medical Entomology Laboratory, Olabisi Onabanjo University, P.M.B. 2002, Ago-Iwoye, Ogun State, Nigeria. Accepted 18 March, 2013 Suitability of Tridax procumbens leaves in laboratory feeding of Bulinus truncatus and Bulinus globosus was assessed in comparison with Lactuca sativa between September and October, 2011. The snails were collected from Eri-lope stream in Ago-Iwoye, while T. procumbens were collected from the Mini Campus of the Olabisi Onabanjo University, Ago-Iwoye, Ijebu North, Southwestern Nigeria. For B. truncatus, fresh, sun-dried and oven-dried T. procumbens were used, while only fresh T. procumbens were used for B. globosus. The mean percentage survivals of B. truncatus fed with fresh, sun-dried and oven-dried T. procumbens compared with those of the corresponding control snails showed no significant difference (2 = 0.51, 1.85, and 2.21, respectively). B. truncatus fed with fresh T. procumbens had the highest mean live-weight percentage increase (46.4%) as compared to those fed with sun-dried and oven-dried (2 = 45.65). The mean percentage survival of B. globosus fed with fresh T. procumbens (79.2%) was similar with that of the control (84.6%) (2 = 0.18). -
Schistosomiasis in Lake Malaŵi and the Potential Use of Indigenous Fish for Biological Control
6 Schistosomiasis in Lake Malaŵi and the Potential Use of Indigenous Fish for Biological Control Jay R. Stauffer, Jr.1 and Henry Madsen2 1School of Forest Resources, Penn State University, University Park, PA 2DBL Centre for Health Research and Development, Faculty of Life Sciences, University of Copenhagen, Frederiksberg 1USA 2Denmark 1. Introduction Schistosomiasis is a parasitic disease of major public health importance in many countries in Africa, Asia, and South America, with an estimated 200 million people infected worldwide (World Health Organization, 2002). The disease is caused by trematodes of the genus Schistosoma that require specific freshwater snail species to complete their life cycles (Fig. 1). People contract schistosomiasis when they come in contact with water containing the infective larval stage (cercariae) of the trematode. Fig. 1. Life cycle of schistosomes (Source: CDC/Alexander J. da Silva, PhD/Melanie Moser) www.intechopen.com 120 Schistosomiasis Schistosome transmission, Schistosoma haematobium, is a major public health concern in the Cape Maclear area of Lake Malaŵi (Fig. 2), because the disease poses a great problem for local people and reduces revenue from tourism. Until the mid-1980’s, the open shores of Lake Malaŵi were considered free from human schistosomes (Evans, 1975; Stauffer et al., 1997); thus, only within relatively protected areas of the lake or tributaries would transmission take place. These areas were suitable habitat of intermediate host snail, Bulinus globosus. During mid-1980’s, reports indicated that transmission also occurred along open shorelines. It is now evident that in the southern part of the lake, especially Cape Maclear on Nankumba Peninsula, transmission occurs along exposed shorelines with sandy sediment devoid of aquatic plants via another intermediate host, Bulinus nyassanus (Madsen et al., 2001, 2004). -

There are indications that the strong seasonal presence (late spring to early fall) of sand tigers in this area is a relatively new phenomenon as local fishermen claim that they had never seen this species in large numbers until recently. We utilized passive acoustic telemetry to monitor seasonal residency, habitat use, site fidelity, and fine scale movements of 35 sand tigers (79 – 120 cm fork length; age 0 - 1) in PKD Bay. Sharks were tracked within PKD Bay for periods of 5 – 88 days during September – October, 2008 and June – October, 2009. All movement data are currently being analyzed to quantify spatial and temporal habitat use, however, preliminary analyses suggest that sharks display a high degree of site fidelity to several areas of PKD Bay. Outside PKD Bay, we documented broader regional movements throughout New England. Collectively, these data demonstrate the that both PKD Bay and New England coastal waters serve as nursery and essential fish habitat (EFH) for neonatal and juvenile sand tiger sharks. -

Now a days, some innovative farmers of Bangladesh started snail culture within their fish farms in the view of producing snail to use as feed for their Prawn (Macrobrachiam rosenbergii), indigenous catfish (Clarius batrachus) farms, domestic duck farms and also as a protein supplement for preparing fish feed. From previous study we know that Bulinus nyassanus growth and survive rate was found well on locally formulated fish diet consisting of 30% crude protein with ingredients comprising fish meal, maize bran, rice bran, soya bean, wheat bran, hemicellulose (binder), vitamin premix and mineral premix. -

Distribution and Habitats of the Alien Invader Freshwater Snail Physa Acuta in South Africa
Distribution and habitats of the alien invader freshwater snail Physa acuta in South Africa KN de Kock* and CT Wolmarans School of Environmental Sciences and Development, Zoology, Potchefstroom Campus of the North-West University, Private Bag X6001, Potchefstroom 2520, South Africa Abstract This article focuses on the geographical distribution and habitats of the invader freshwater snail species Physa acuta as reflected by samples taken from 758 collection sites on record in the database of the National Freshwater Snail Collection (NFSC) at the Potchefstroom Campus of the North-West University. This species is currently the second most widespread 1 alien invader freshwater snail species in South Africa. The 121 different loci ( /16- degree squares) from which the samples were collected, reflect a wide but discontinuous distribution mainly clustered around the major ports and urban centres of South Africa. Details of each habitat as described by collectors during surveys were statistically analysed, as well as altitude and mean annual air temperatures and rainfall for each locality. This species was reported from all types of water-bodies rep- resented in the database, but the largest number of samples was recovered from dams and rivers. Chi-square and effect size values were calculated and an integrated decision tree constructed from the data which indicated that temperature, altitude and types of water-bodies were the important factors that significantly influenced the distribution ofP. acuta in South Africa. Its slow progress in invading the relatively undisturbed water-bodies in the Kruger National Park as compared to the recently introduced invader freshwater snail species, Tarebia granifera, is briefly discussed. -
A Thesis Submitted for the Degree of Master of Philosophy from the University of London and the Diploma of Membership of Imperial College
TAXONOMIC STUDY OF THE BULINUS AFRICANUS GROUP IN KENYA BY RICHARD ARCHER A thesis submitted for the degree of Master of Philosophy from the University of London and the Diploma of Membership of Imperial College Department of Pure and Applied Biology, Imperial College, London SW7 and Experimental Taxonomy Unit, Department of Zoology, British Museum (Natural History), London SW7 5BD. 2 ABSTRACT Certain species of the Bulinus africanus group have been implicated in the transmission of Schistosoma haematobium in Kenya. Full taxonomic resolution of the group has previously been hampered by extensive intergradation of form between certain taxa. The major source of difficulty has been the inadequate quantification of traditional characters, particularly those on the shell. With the advent of various numerical and experimental techniques there is a need for re-assessment of shell morphology. This study involved the morphological characterisation of populations from Western and Central Kenya, using new and traditional shell variables. These were standardised and quantified morphometrically, producing two data sets: PI, consisting of four morphologically distinct samples; and P2, consisting of 10 larger samples, less visually distinct. PI and P2 were subjected to multivariate analysis, principally Canonical Variates Analysis and Principal Components Analysis. This study suggests that Principal Components Analysis is of limited use in resolving samples using shell variables. Canonical Variate Analysis is a more useful technique since it minimises the effects of variation within each sample whilst maximising variation between samples. Numerical analysis suggests the presence of three morphotypes among these samples, corresponding to the b.africanus^B.nasutus and B.globosus/ugandae forms. The effects of isometric and allometric growth are discussed. -
