Two decades of research have established newer pathogens and techniques in establishing several organisms of diarrhoeal diseases as aetiological agents. It is now possible to detect an agent in 80% of the situation of diarrhoea in a standard laboratory. The brief review describes the list of pathogens, their diagnostic techniques with short description on clinical and epidemiological status.

Lutzomyia longipalpis Lutz & Neiva, 1912 (Diptera, Psychodidae), is the primary vector of Leishmania infantum Nicole, 1908, the etiological agent of American visceral leishmaniasis. During their development, sandfly larvae pass through four instars, consuming soil particles enriched with microorganisms and decomposing organic material. In numerous insect species, the intestinal epithelium not only secretes digestive enzymes and absorbs digested nutrients but also carries out additional functions, such as regulating luminal pH and facilitating the absorption or secretion of ions and water.

Cruzipain (CZP) is an essential cysteine protease of , the etiological agent of Chagas disease, and a promising druggable target. To date, no CZP inhibitors have reached clinical use, with research efforts mostly hampered by insufficient potency, limited target selectivity or lack of bioactivity translation from the isolated enzyme to the parasite in cellular environments. In this study, we report the design of , a 1,2,3-triazole-based targeted covalent inhibitor with nanomolar potency (IC = 28 nM) and null inhibition of human cathepsin L.

Preventive interventions are expected to substantially improve the prognosis of patients with primary liver cancer, predominantly hepatocellular carcinoma (HCC) and cholangiocarcinoma. HCC prevention is challenging in the face of the evolving etiological landscape, particularly the sharp increase in obesity-associated metabolic disorders, including metabolic dysfunction-associated steatotic liver disease (MASLD). Next-generation anti-HCV and HBV drugs have substantially reduced, but not eliminated, the risk of HCC and have given way to new challenges in identifying at-risk patients.
