“…Furthermore, contact with infected feces causes a higher risk of endo-parasitism and Salmonella infection. A study conducted in selected villages of KwaZulu-Natal province of South Africa found A. galli to be a common endo-parasite present in all sampled sites with an infection rate of 58.3%, while H. beramporia and Heterakis gallinarum were present in only three sampled sites ( 14 ). The high pool prevalence of helminth infections is known to have an impact on welfare ( 40 ), production performance ( 41 ) of free-range chickens and susceptibility to secondary infections, thus causing significant economic losses for farmers ( 42 ).…”

Helminth parasite infections are widespread in smallholder farming systems affecting farmers and livestock animals. There are pathogenic parasites that populate the gut of their host and coexist closely with the gut microbiota. The physical and immunological environment of the gut can be modified by parasites and microbiota creating a wide range of interactions. These interactions modify the development of infection, affects overall host health, and can modify the way a host interacts with its bacterial microbiota. In addition, where there is a high worm burden parasites will affect the health of the host and intestinal tract colonization. This review highlights key studies on the interaction between helminth parasites and the intestinal microbiome to understand the relationship between parasitic worm infections and gut microbiome health in chickens. Finally, the review discusses modulations, molecular changes, and the importance of helminth-microbiome interactions for the host.

“…Pigeons and other wild birds act as the reservoir hosts of A. galli . The prevalence of ascaridiosis ranges between 70 and 80%, especially in indigenous semiscavenging chickens ( Mlondo et al, 2022 ; Shifaw et al, 2023 ). The life cycle of A. galli is direct.…”

“…There are partial ultrastructural data about H. gallinarum specie [8][9][10][11][12][19][20][21][22]. Nevertheless, identification of the H. gallinarum nematode at the molecular level (through mitochondrial and ribosomal markers) and phylogenetic analysis [23][24][25][26], characteristics [27], identification through PCR [28,29], etc. studies have been conducted.…”

HE NEMATODES of the genus Heterakis are similar in appearance and a number of morphological characteristics. Therefore, determination of nematodes creates certain difficulties. H. gallinarum helminth is one of the widespread species of the genus. In the current study, the body wall of the parasite of the H. gallinarum nematode was studied at the ultrastructural level with the help of light and electron microscopic methods, and the obtained results were compared with the structures of the covering tissue of other species of the family. It was found that the bady wall of the nematode consists of 3 layers. The cuticle of the helminth is made up of 8 layers. In both individuals of the helminth, the lateral alae consist of 3 main layers. Homogeneous and fibrillar layers are many times thicker than other parts of the helminth's body. While the shape of the cuticle of both male and female H. gallinarum nematode is smooth throughout the body, 2 different shapes have been found around the bulb. This sign is not mentioned in other species of the family. Tubular structures were found between the basal part of the cuticle and the hypodermis of the studied helminth. The nervous system of the parasite is orthogonal, and the muscular type is polymyar. The number of muscle cells in between two ridges of the helminth varies from 19 to 28, depending on the sex of the worm and the part of the body of the helminth.
