We documented the blowfly maggot infestation with the morphometry of larvae.The larvae are nearly transparent, usually more or less flattened. They were identified with their twelve body segments and internal chitinous cephalopharyngeal skeleton having oral hooks and characteristically recessed posterior spiracles. Two strongly sclerotized posterior spiracles with narrow peritremal ring appeared as finger like projection. The larvae sizes are in the range of 7.0 to 12.0 mm. in length with the average of about 10.0 ± 0.1 mm.The warm climate of March is the best suited for incubation of myiasis producing maggots on toads.

The disease has been reported with a considerably low infection rate among the children compared to that of adults to date, but the reasons are still not very clear to the scientists. As infants are naturally prone to a wide range of viruses, it is fascinating to understand that they are being least affected by SARS-CoV-2. Expression of Angiotensin Converting Enzyme 2 (ACE2) and Transmembrane Serine Protease (TMPRSS2) Receptors have been thought to play a critical role in the expression of the disease. The shared genetic or environmental traits and socioeconomic condition might predispose for transmission dynamics of this coronavirus in children.The children genetic association may have risk of small amount although genetic variants o...

In this study, stationary phase of promastigotes exposed to radiation doses in the range 10-20 krad (standard dose) resulted in significant parasitization of mononuclear phagocytic system in vitro. However, promastigotes irradiated with 20krad consistently resulted in higher parasitization and optimum infection after acquiring the shape of amastigote- like organism than those exposed to either higher or lower radiation doses. It was observed that 10 krad was necessary to immobilize immediately the organisms, whereas only 30 krad rendered them noninfective and 40-50 krad made promastigotes unable to recognize the binding ligand for attachment to macrophage cell. In comparison to the irradiated parasite, the rate of phagocytosis of 20 krad irradiated cells, were...

Immunoglobulin E (IgE)-mediated food allergy is the most common type of adverse reaction towards wheat proteins. Increased intestinal permeability after gluten exposure occurs in all individuals. Both genetic and environmental factors influence the nature of reactivity to gluten and phenotypic expression of enteropathy. Gluten can trigger adverse inflammatory, immunological and autoimmune reactions in some people. It can produce abroad spectrum of gluten related disorders. This comprehensive review explored to identify the strengths, challenges, and future prospects of animal models in basic and applied wheat protein allergy evidenced from clinical trials and its role as potential pathogenic cofactor.
