Human schistosomiasis is a common parasitic disease endemic in many tropical and subtropical countries. One barrier to achieving long-term control of this disease has been re-infection of treated patients when they swim, bathe, or wade in surface fresh water infested with snails that harbor and release larval parasites. Because some snail species are obligate intermediate hosts of schistosome p...

The giant freshwater prawn, Macrobrachium rosenbergii, is an economically important species. It is a euryhaline shrimp, surviving in wide-range salinity conditions. A change in gene expression has been suggested as an important component for stress management. To better understand the osmoregulatory mechanisms mediated by the gill, a subtractive and suppressive hybridization (SSH) tool was used...

An epizootic bacterial infection in the giant freshwater prawn Macrobranchium rosenbergii occurred in Taiwan from May to June 1999. The cumulative mortality was approximately 30 to 75%. The diseased prawns showed opaque and whitish muscles and were approximately 2 mo old with total lengths from 5 to 6 cm. Histopathologically, they showed marked edema and necrotic lesions with inflammation in th...

The male Macrobrachium species (giant freshwater prawn) typically achieve better growth and a larger harvest size than females. Hence, it is clear that the monosex culture of all-male prawn populations would be inexpensively advantageous. This study aimed to determine whether androgenic gland (AG) ablation induces sex reversal giant dacqueti. AG was ablated through bilateral microsurgery (AG ab...

Bacteriocin has been used widely in industry as a Backgrounds biopreservative agent. The objective of the present study was to investigate the potency of Bacteriocin isolated from tiger prawn and Penaeus monodon freshwater shrimp as an anti-bacterial on fish. Macrobrachium rosenbergii : A total of ten candidates of probiotic bacteria consisted of five Methods isolates from tiger shrimps (H1, H2...

Background Dystrophin, an essential protein functional in the maintenance of muscle structural integrity is known to be responsible for muscle deterioration during white spot syndrome virus (WSSV) infection among prawn species. Previous studies have shown the upregulation of dystrophin protein in Macrobrachium rosenbergii (the giant freshwater prawn) upon white spot syndrome virus (WSSV) infect...

The effect of formalin on the organoleptic parameters, biochemical composition and storage quality of iced and frozen stored giant freshwater prawns (Macrobrachium rosenbergii) was investigated. The organoleptic characters such as appearance, textural condition, colour, odour of both formalin added and non-added prawns were evaluated. The quality of non-added prawns was judged good up to first ...

In this study, the first phase of Toxicity Identification Evaluation (TIE) was used to characterise the major toxicants present in a Malaysian landfill leachate, using multispecies bioassay. Freshwater fish (Rasbora sumatrana), freshwater prawn (Macrobrachium lanchesteri) and tomato seeds (Lycopersicon esculentum) were chosen as test species based on local availability, as well as their broad s...

Physico-chemical factors of river Pumba, Kerala has been analyzed to understand its relationship with the distribution of Giant river prawn, Macrobrachium rosenbergii in the water body. Water samples were taken from two sites on the basis of presence and absence of juveniles. Analysis of temperature, pH, turbidity, dissolved oxygen, dissolved carbon dioxide and salinity of the water samples rev...
