Some of the parasites are specific to individual species while others may be transmissible to University, Andhra Pradesh humans as zoonotic in nature. Impairment of the health condition of the animals leads to huge economic India loss interns of productivity and reproduction. Parasitic diseases in livestock can be controlled by geographical location, type of host and their manage mental practices. Conventional methods of B Sudhakara Reddy controlling parasites use synthetic chemotherapeutic drugs. In a safe manner, control of the animal Assistant Professor, parasites can be done by the biological control which means maintenance of natural enemies which Faculty of Veterinary Medicine, maintain a parasitic population at the lower level. Recently, parasitic castration has a role in the control Department of Veterinary of the parasitic diseases. In this, with help of different parasites, reproduction of the other parasites which Clinical Complex, College of are harmful to the animals can be reduced. This would be a case of direct parasitic castration by feeding Veterinary Science, Proddatur, on gonads of the hosts or indirectly, diverting the host energy from gonad development. -

Digenea, Microphallidae) and Relative Merits of Two-Host Microphallid Life Cycles
Parasitology Research (2018) 117:1051–1068 https://doi.org/10.1007/s00436-018-5782-1 ORIGINAL PAPER Microphallus ochotensis sp. nov. (Digenea, Microphallidae) and relative merits of two-host microphallid life cycles Kirill V. Galaktionov1,2 & Isabel Blasco-Costa3 Received: 21 July 2017 /Accepted: 23 January 2018 /Published online: 3 February 2018 # Springer-Verlag GmbH Germany, part of Springer Nature 2018 Abstract A new digenean species, Microphallus ochotensis sp. nov., was described from the intestine of Pacific eiders (Somateria mollissima v-nigrum) from the north of the Sea of Okhotsk. It differs from other microphallids in the structure of the metraterm, which consists of two distinct parts: a sac with spicule-like structures and a short muscular duct opening into the genital atrium. Mi. ochotensis forms a monophyletic clade together with other congeneric species in phylograms derived from the 28S and ITS2 rRNA gene. Its dixenous life cycle was elucidated with the use of the same molecular markers. Encysted metacercariae infective for birds develop inside sporocysts in the first intermediate host, an intertidal mollusc Falsicingula kurilensis. The morphology of metacercariae and adults was described with an emphasis on the structure of terminal genitalia. Considering that Falsicingula occurs at the Pacific coast of North America and that the Pacific eider is capable of trans-continental flights, the distribution of Mi. ochotensis might span the Pacific coast of Alaska and Canada. The range of its final hosts may presumably include other benthos- feeding marine ducks as well as shorebirds. We suggest that a broad occurrence of two-host life cycles in microphallids is associated with parasitism in birds migrating along sea coasts. -
Trematode Infection Correlates with Shell Shape and Defence Morphology in a Freshwater Snail
699 Trematode infection correlates with shell shape and defence morphology in a freshwater snail E. P. LEVRI*, J. DILLARD and T. MARTIN Division of Math and Sciences, 3000 Ivyside Park, Penn State – Altoona, Altoona, PA 16601, USA (Received 21 October 2004; revised 14 December 2004; accepted 15 December 2004) SUMMARY Parasitism often influences the phenotype of individuals. Many of the resulting changes are due to changes in resource allocation that come with infection. Here we examine the effect of a trematode parasite on the shape and defence morphology of a New Zealand freshwater snail, Potamopyrgus antipodarum. The trematode Microphallus sp. asexually produces hundreds of metacercarial cysts in the snail. The length, width and 2-dimensional area of each snail were measured. Snails were also assessed for their degree of spininess. Snails were dissected to determine gender, brooding condition and parasitism. Snails infected with Microphallus sp. were found to be significantly less spiny than uninfected snails. Microphallus-infected snails were also found to have a significantly greater width to length ratio at larger sizes than their uninfected counterparts. These trends could be explained in at least 3 ways. (1) Infection causes the snails to not produce spines and to become wider. (2) Spiny and narrower snails are more likely to die when they become infected. (3) Spiny and narrower snails are more resistant to infection. The changes in phenotype observed are unlikely to be adaptive for either the host or parasite and probably represent physiological by-products of the host-parasite relationship. Key words: Potamopyrgus antipodarum, Microphallus, trematode, shell morphology, spines. -

FA is predicted to increase in response to environmental stress, 17 including parasite infection. In addition, theory predicts higher FA in sexually selected traits, due to their 18 greater sensitivity to stress. Here we investigate the relationships between FA, parasitism and 19 reproductive fitness in two species of gammarid crustacean, incorporating both sexual and non-sexual 20 traits. -

Additionally, the salt ponds offers coastal breeding and nursery habitat to fishes and invertebrates providing abundant amphipods potentially useful as a resource in aquaculture. Fishmeal and fish oil are necessary food resources to support aquaculture of carnivorous species due to their omega-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA). Their dependence on limited fisheries constrains growth of aquaculture and the need for n-3 LC-PUFA recommends the development of more sustainable food sources. -
