Yielding Super Shrimps Can Prevent Human Disease

Single-sex prawns may assist alleviate poverty, cut back illness and shield the atmosphere, in response to researchers at Ben-Gurion University of the Negev (BGU) who’ve developed a monosex prawn that will make this profitable trifecta attainable.

In a groundbreaking examine in Nature’s Scientific Reports, the BGU group highlights the event of a “tremendous shrimp” which, for the primary time, solely produces feminine offspring. The emergence of all-feminine inhabitants might each improve aquaculture yields in addition to function a pure agent to forestall the unfold of dangerous, water-certain parasites.

To attain efficient biotechnology for all-female aquaculture within the economically necessary prawn (Macrobrachium rosenbergii), the researchers achieved — for the primary time — WW males utilizing androgenic gland cells transplantation which induced full intercourse-reversal of WW females to purposeful males. Crossing the WW males with WW females yielded all-feminine progeny missing the Z chromosome.

The analysis is being carried out by BGU Prof. Amir Sagi, who additionally serves as a member of the National Institute for Biotechnology within the Negev (NIBN), and his Ph.D. scholar, Tom Levy, in collaboration with Enzootic, a Beer-Sheva, Israel-primarily based startup firm specializing in all-feminine monosex aquaculture biotechnologies.

The publication follows an examine revealed in July in Nature Sustainability exhibiting that freshwater prawn species function a biocontrol agent by preying on aquatic snail species. The snails function intermediate hosts of the parasite that causes schistosomiasis in sub-Saharan Africa.

Schistosomiasis is an acute and persistent illness brought on by parasitic worms that may end up in extreme stomach pain, diarrhea, and blood within the stool. In women, urogenital schistosomiasis might current with genital lesions, vaginal bleeding, ache throughout sexual activity, and nodules within the vulva. In men, urogenital schistosomiasis can induce pathology of the seminal vesicles, prostate, and different organs. The World Health Organization estimates that not less than 220.8 million individuals every year require preventive therapy for the illness.
