“…For the parasite measurement, the mean length is 244.74±16.53 and the mean length is 54.04±8.42, respectively. From this study, the size of gregarine parasites are closely related to the parasites that have been found by Prasadan and Janardan (2001) and Tuntiwaranuruk et al (2008) with the measurement range size is 213.0-317.0 µm and 230.0-361.0µm, respectively. Detailed information on the measurement range size of the present study and previous report are varied (Table 3).…”

Highlight ResearchThis is the first report of the occurrence of gregarine species in Peninsular Malaysia.The information of these findings will lead to the identification of species using genetic analysis.This information can help to solve the cultured problem of the Macrobrachium rosenbergii industry worldwide. AbstarctStudies on the parasite of prawn are likely to be important due to the commercial value of the prawn. Investigation study about gregarine parasites of M. rosenbergii in Malaysia is still lacking. Objective of this study is to determine the occurrence of gregarine parasites in shrimp, M. rosenbergii from Setiu Lagoon, Terengganu. The study was done specifically to observe the prevalence and the mean intensity of the parasites which include the morphological prevalence and parasitological study. Prevalence of the parasites in this study is 42.4% with 95% Cumulative Index (CI) 25.6% to 59.3% and value of Odd Ratio (OR) is 0.74 (CI = 0.29 to 1.88). Two structures of the gregarine which is gamont and syzygy found in this study are closely related to morphology characteristic of gregarine in the previous report.

“…The study of parasites and diseases affecting molluscs with ecological and economic interests is critical for the management of natural stocks and aquaculture (Boehs et al ., 2010). The most severe mussel diseases are caused by viruses, bacteria and protistans, which can be responsible for mortality outbreaks, thus posing a substantial commercial impact (Tuntiwaranuruk et al ., 2008; Ceuta & Boehs, 2012; Mladineo et al ., 2012). To a lesser extent, other diseases are caused by ciliates, turbellarians (Cova et al ., 2015), trematodes (Özer & Güneydağ, 2015) and fungi (Santos et al ., 2017).…”

Variation of parasite and fungi infection between farmed and wild mussels (Mytilus galloprovincialis Lamarck, 1819) from the Adriatic Sea

Investigation of parasites and diseases affecting molluscs of ecological and economic interest is critical for the management of native stocks and aquaculture. In recent years, much attention has been devoted to investigating the World Organisation for Animal Health listed infectious diseases, so that communities can be prepared to attend public health emergencies and avoid severe income losses. In this context, the health status of Mytilus galloprovincialis Lamarck, 1819 was analysed in two aquaculture sites (Strunjan Bay and Piran Bay, Slovenia), and in four natural mussel beds (Adriatic Croatia International Marinas Pula and Rovinj and St Catherine, Croatia; Marina Koper, Slovenia) along the coast of the northern Adriatic Sea. The mussels were sampled in February and April 2014, and processed for histological examination of several endosymbionts and pathogens that frequently occur in mytilid mussels. Endosymbionts and pathogens were not detected in farmed mussels. Prokaryotic inclusion bodies, the protozoan Nematopsis, Ancistrocoma-like ciliates, haplosporidian-like plasmodia, turbellarian Urastoma cyprinae, and basophilic inclusion bodies were observed in digestive gland cryosections of wild mussels from the coastal region of the northern Adriatic. Fungal spores of Psilocybe sp., Ulocladium sp. and Alternaria sp. were detected between the digestive tubules based on their morphology. Diagnostic PCR did not reveal infection with Marteilia refringens during the studied period, neither in wild nor farmed mussels. We confirmed the site effects on prevalence of infected mussels. Thus, we can conclude that wild areas are more exposed to endobionts and parasites than aquaculture sites.

“…The disease problem is one of the serious threats to aquaculture production [1][2][3]. Diagnosis of parasites and monitoring for disease pathogen presence in farms and natural bivalve populations need to be intensively practiced to secure the Malaysian aquaculture industry in the future.…”

Malaysia is known as a country that experience two main seasonal patterns, i.e., monsoon and non-monsoon season. Three different categories of seasons based on the quantity of rainfall were divided by previous studies started from January to December 2018, which are dry season, moderate season and rainy season. Wild bivalve, Anadara cornea populations at Setiu Lagoon in Terengganu, Malaysia was examined for gregarine parasites for a year. The objective of this study was to associate the incidence of gregarine in common wild bivalves, A. cornea (Reeve, 1844) concerning seasons and water quality parameters. From the study, the total number of phagocytes found was n = 33,239, with a total of 480 host samples. The total prevalence of the parasites was 97.5%, with a 95% confidence interval value which was CI=96.1% to 98.9%. The prevalence of the parasites was significantly higher during the rainy season as compared to dry and moderate seasons. The findings also proved that the intensity of the parasites decreased at every transition of season. In-depth, the correlation between the prevalence of the parasites vice versa, season, and water quality might be contributed to the intensity of the parasite infestation needs to be clarified.
