A Review on Heat Stress in Broiler Chickens: Mechanisms, Effects and Mitigation Strategies

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Heat stress caused by high temperature and humidity compromises broiler health, welfare, and productivity by reducing feed intake, growth performance, and feed efficiency, while increasing mortality, oxidative stress, metabolic disturbances, intestinal dysfunction, gut dysbiosis, immune suppression, and meat quality deterioration.

Light microscopy analysis of cell death in ΔRep oocysts.

, 2014
A. Photographs of representative mosquito midguts on days 14 and 21 post infection. Control and ΔRep parasites express GFP in most oocysts at day 14 post infection whereas by day 21 most of the ΔRep oocysts have lost the GFP fluorescence. Top panel shows

Acute Diarrheal Disease Associated With Climate Variability and Water Supply System Configuration: An Ecological Study in Brazil

Water Environment Research, Volume 98, Issue 9, September 2026.
Acute diarrheal disease rates are associated with seasonality and the type of water supply system. ABSTRACT Acute diarrheal disease (ADD) remains a major public health problem in low‐ and middle‐income countries, where vulnerabilities in water supply systems (WSSs) are associated with increased exposure to disease.

Reproductive Morphometric Plasticity in Gregarina polymorpha Infecting Tenebrio molitor Larvae

Journal of Eukaryotic Microbiology, Volume 73, Issue 5, September/October 2026.
ABSTRACT Morphological variability remains one of the principal challenges in the taxonomy and species delimitation of gregarines (Apicomplexa: Gregarinomorphea). In the present study, we investigated morphometric variability in gametocysts and syzygies of Gregarina polymorpha infecting Tenebrio molitor larvae through quantitative morphometric and ...

Scalable cryopreservation of infectious Cryptosporidium hominis oocysts by vitrification.

, 2023
Cryptosporidium hominis is a serious cause of childhood diarrhea in developing countries. The development of therapeutics is impeded by major technical roadblocks including lack of cryopreservation and simple culturing methods.

Impact of artemether–lumefantrine treatment, circadian rhythm, and serum replacement on the infectiousness of wild Plasmodium falciparum gametocytes to Anopheles gambiae sensu stricto mosquitoes

Frontiers in Malaria
BackgroundIn the era of asymptomatic gametocytemia, carriers are scarce but serve as key reservoirs for Plasmodium falciparum gametocytes. Transmission-blocking interventions (TBIs) are gaining attention, considering factors such as artemether ...

Methods of Quantification and Characterization of Coccidian Oocysts [PDF]

, 2016
Coccidiosis is a major economic and health risk in the poultry industry. The oocysts of the causative agent of coccidiosis are excreted in animal feces and must be ingested by a new host for a new infection to begin.

Giardia duodenalis cysts of genotype a recovered from clams in the Chesapeake Bay subestuary, Rhode River [PDF]

, 1999
Filter-feeding molluscan shellfish can concentrate zoonotic and anthroponotic waterborne pathogens. Cysts of Giardia sp. were detected by immunofluorescent antibodies in tissues of the clams Macoma balthica and M. mitchelli from Rhode River, a Chesapeake
