“…They may even cause death since they interfere with respiration and locomotion (Overstreet 1973). Transmission of ciliate parasites increases during summer in tropical or subtropical climates because of the physicochemical conditions of the farm (Norma et al 2009), increasing metabolism and molting of decapods host occurred due to heavy amount of solar energy (Rhode 1992;Jayasree et al 2001).…”

“…Thus from the above discussion it can be concluded that heavy infestations of epibionts and parasites are expected when the rate of transmission is increased due to high stocking density and variations of environmental parameters (e.g., amount of ammonium, nitrate, and dissolved oxygen levels) and the consequences of pond fertilization (Kautsky et al 2000;Gualteros-Rodríguez 2003). During summer months due to high intensity of solar energy the moulting process is favoured (Rhode 1992;Jayasree et al 2001), thus enhancing the invasion of parasites. So adequate measures should be taken in the susceptible months to avoid protozoan infections.…”

“…Their abundant presence can interfere with the breathing and mobility of the host. The Zoothamnium infections are at their peak during monsoon and postmonsoon months and these infections appear to be governed directly by salinity of the habitat and indirectly by the rainfall (Jayasree et al 2001).…”

There is a delicate balance between the host, pathogen and environment. Aquatic organisms, including shellfish, respond directly to climatic changes in their biological environment as their metabolic processes are influenced by temperature, salinity, and oxygen levels. Certain environmental conditions are more conducive to diseases than others among which water temperature is significantly associated with disease outbreak. The present study showed that Peneaus monodon of Sundarbans serve as a host for many protozoan parasites and epibionts including ciliates, gregarines and microsporidia. The protozoan parasites also require a particular environmental condition for their maximum growth and survival. The intensity of infection significantly increases with rise in temperature (P < 0.05) following a definite trend but no significant relationship between infection rate of ciliates and pH of water. In case of gregarine parasites significance (P < 0.05) exists among infection rate and temperature as well as pH of the farm water. Microsporidian parasites do not follow any significant seasonal trend in infecting the host P. monodon.

“…In the present survey, P. manipuriensis, also harboured other metacercariae of the microphallid trematode genus-Microphallus, beside P. heterotremus. Metacercarial stages of Microphallus have been earlier reported from sand crabs and brackish-water prawns (Anantaraman and Subramoniam 1976;Jayasree et al 2001). Metacercariae of Microphallus indicus have been reported from B. lugubris in Meghalaya (Goswami et al 2013).…”

Food-borne trematode infections, which are mainly transmitted through consumption of inadequately cooked or raw fish and crabs, affect a large section of population, particularly in Southeast Asian countries, thus eliciting a remarkable morbidity and causing serious damage to health. In India, centering in several mountainous regions of the Northeast, the natives have the habit of consuming such fish or crabs that still sustain viable infective larval stage (metacercaria) of trematode flukes in their muscle tissue. The present study was undertaken to ascertain the spectrum of metacercarial diversity in commonly edible freshwater fishes and crab species in the northeastern state of Manipur and to adjudge their zoonotic potential, if any. Commonly edible fishes belonging to 15 species from 12 localities and crabs belonging to 2 species from 11 localities across Manipur state were surveyed for the purpose. The study revealed that 3 species of fishes (Channa punctatus, C. straitus and Wallago attu) harboured 4 different types of metacercariae belonging to 4 trematode families-Euclinostomum heterostomum (Clinostomidae); Lophosicyadiplostomum sp. and Posthodiplostomum sp. (Diplostomidae); and Polylekithum sp. (Allocreadiidae) in addition to adult flukes of Isoparorchis hypselobagri (Isoparorchiidae). Among these, metacercariae of Posthodiplostomum showed the highest prevalence (2.33 %) though a low abundance, while for other species the prevalence ranged between 0.25 and 1.19 %. The crab species (Barythelphusa lugubris masoniana and Potamiscus manipuriensis) were found infected with 4 different types of metacercariae representing the genera Paragonimus (Troglotrematidae) and Microphallus (Microphallidae). The paragonimids showed a higher rate of occurrence (*4-25 %) compared to microphallids (*15 %). The crustaceans surveyed emerged as prospective intermediate hosts for lungflukes. Identifying the potent vectors for zoonotic parasites helps in control measures towards their transmission to higher mammals.

“…and Epistylis sp. can hinder moulting and growth, causing death in cases of extreme parasitosis (Jayasree et al 2001 (Edgerton et al 2002), and thus appear to have no strong host preference.…”
