Background: Parasites are a major concern for profitable poultry production worldwide as they impede the health, welfare and production performance of poultry.
Objectives: The present study was designed to detect the diversity of parasitic fauna and associated factors of gastrointestinal (GI) helminths and lice in indigenous chickens.
Methods: A total of 310 indigenous chickens were collected from different villages at Gauripur and Mymensingh Sadar, Mymensingh, and Bangladesh, and various parasites were identified.

The development of turkey farming is significantly restrained by parasitic diseases, which have become widespread and cause significant economic losses to specialized- and homestead farms. This study aimed to determine the prevalence of endoparasites in turkeys of different age groups under different maintenance systems and the nature of patho-anatomical changes depending on the course of the disease. A total of 1,869 samples of fecal from turkeys were studied.

Extensive backyard chickens are one of the most common production systems in low-income and middle-income countries (LMICs). In this production system, chickens are exposed to infectious forms of parasites as a result of the outdoor access and scavenging behaviour. Heterakis gallinarum is one of the most common nematode parasites present in the environment, and estimating its global and regional prevalence is essential for attributing the economic losses in extensive backyard chickens.

Article Synopsis
- During parasite infections, the liver in chickens may prioritize immune functions over metabolic activities, impacting overall health.
- Infections with Ascaridia galli and Heterakis gallinarum result in decreased feed intake, nutrient absorption, and weight gain, while H. gallinarum also leads to a co-infection with Histomonas meleagridis that can damage liver tissue.
- A study on three chicken strains showed significant differences in gene expression due to infections, with many genes related to immune responses being up-regulated, indicating a shift in liver function from metabolism to immunity when faced with mixed parasite infections.
