“…Studies have shown that DM is potentially harmful to animal development. In insects, DM exposure during the larval stage reduced body weight and prolonged development in Chrysomya megacephala [24]. In fish, exposure of zebrafish embryos to low-dose DM for 96 h significantly reduced larval body length and swim bladder [25]; it also resulted in defective larval locomotion in zebrafish [26].…”

Deltamethrin (DM), a Type II pyrethroid, is widely used worldwide in agriculture, household applications, and medicine. Recent studies have shown that DM exerts a variety of toxic effects on organs such as the kidney, heart muscle, and nerves in animals. However, little is known about the effects of high-dose DM on growth and development, and the mechanism of toxicity remains unclear. Using the Caenorhabditis elegans model, we found that high-dose DM caused a delay in nematode development. Our results showed that high-dose DM reduced the activation of the endoplasmic reticulum unfolded protein response (UPRER). Further studies revealed that high-dose DM-induced developmental toxicity and reduced capacity for UPRER activation were associated with the IRE-1/XBP-1 pathway. Our results provide new evidence for the developmental toxicity of DM and new insights into the mechanism of DM toxicity.

“…Lymphatic filariasis, in which the adult worms of Wuchereria bancrofti are found in the lymphatic system, is endemic in India (Uttar Pradesh, Bihar, Jharkhand, Orissa, Kerala, and Gujarat), Nepal, and Sri Lanka. [153][154][155] It is transmitted by mosquitoes of the genera Culex, Mansonia, and Anopheles. Approximately half of the 120 million global cases are seen in Southeast Asia.…”

South Asian Transplant Infectious Disease Guidelines for Solid Organ Transplant Candidates, Recipients, and Donors

et al. 2023

These guidelines discuss the epidemiology, screening, diagnosis, posttransplant prophylaxis, monitoring, and management of endemic infections in solid organ transplant (SOT) candidates, recipients, and donors in South Asia. The guidelines also provide recommendations for SOT recipients traveling to this region. These guidelines are based on literature review and expert opinion by transplant physicians, surgeons, and infectious diseases specialists, mostly from South Asian countries (India, Pakistan, Bangladesh, Nepal, and Sri Lanka) as well as transplant experts from other countries. These guidelines cover relevant endemic bacterial infections (tuberculosis, leptospirosis, melioidosis, typhoid, scrub typhus), viral infections (hepatitis A, B, C, D, and E; rabies; and the arboviruses including dengue, chikungunya, Zika, Japanese encephalitis), endemic fungal infections (mucormycosis, histoplasmosis, talaromycosis, sporotrichosis), and endemic parasitic infections (malaria, leishmaniasis, toxoplasmosis, cryptosporidiosis, strongyloidiasis, and filariasis) as well as travelers’ diarrhea and vaccination for SOT candidates and recipients including travelers visiting this region. These guidelines are intended to be an overview of each topic; more detailed reviews are being published as a special supplement in the Indian Journal of Transplantation.

“…Studies that demonstrate the efficiency of chemical agents such as permethrin and deltamethrin in the control of C. megacephala are available in literature (Sukontason, et al, 2005;Oliveira, et al, 2021). However, the indiscriminate use of chemical controllers causes environmental damage and exposes living organisms to harmful molecules (Nascimento & Melnyk, 2016;Nicolopoulou-Stamati, et al, 2016), besides selecting populations of resistant insect pests (Sparks & Nauen, 2015).…”

Beauveria bassiana is an entomopathogenic fungus widely used in pest management. After contact with target organisms, fungal conidia germinate and colonize tissues and organs, causing death by starvation and/or septicemia. Chrysomya megacephala is an insect pest with worldwide distribution. Its larvae cause secondary myiasis in animals of interest, and adults are pathogen vectors. This study aimed to analyze the effects of the Ballvéria® biopesticide on the midgut of C. megacephala third-instar maggots. Four concentrations (1, 1.5, 2, and 4%) of the biopesticide were applied to an artificial diet, followed by conditioning of the maggots. Mortality data and samples for histological and ultrastructural analysis were collected every 24 h, for 144 h. Mortality data were analyzed using SPSS 25.0, and lethal concentrations (LC50 and LC90) were calculated using Probit regression. Concentrations of 2 and 4% resulted in mortality rates of 26 and 36%, respectively. LC50 and LC90 were estimated at 5.3 and 10.9%, respectively. Observational, histological, and ultrastructural analyses revealed the presence of tegumentary melanizations, conidia in the midgut, spacing in the basal labyrinth, degeneration of microvilli, absence of the peritrophic membrane, fungal extrusion on the external surface of the midgut, and dispersion of hyphae, conidiophores, and conidia close to muscle fibers. Internally, hyphae are located on microvilli and cell projections. Our data confirm that the Ballvéria® biopesticide causes cytotoxic effects in the midgut of C. megacephala maggots and can be used as a sustainable alternative in its biological control for Integrate Pest Management.
