Abstract

Non-descriptive, indigenous chickens (NDICs) in Bangladesh are commonly reared in scavenging system. Here, we describe the prevalence and pathological impacts induced by mite infestations in NDICs. We found that 47.4 % of NDICs (185 out of 390) were infested with three species of mites namely Trombicula spp. (53.1 %), Knemidocoptes mutans (scaly leg mites/SLM, 15.1 %) and Dermanyssus gallinae (red mites of poultry/PRM, 2.8 %). Sex, age and seasons significantly (p < 0.05) influenced the prevalence of mite infestations. Trombiculid mites produced more specific lesions characterized by circumscribed disc-shaped notches with attached bright red colored mites, which were commonly found in breast, fluff and thigh. Destruction of the epidermis, proliferation of fibrous connective tissues along with massive infiltration of heterophils and lymphocytes were predominant. Thick, rough and ragged appearances with encrustation of the skin of leg were found grossly in SLM infestations. Histologically, hyperkeratosis, acanthosis, massive infiltrations of reactive cells and cross-sections of parasites were detected. PRM induced petechial hemorrhages, papules, necrosis, rupture of the feather follicles and scab formations. Hyperkeratosis and huge infiltration of mononuclear cells and granulocytes were evident. Taken together, mite infestation is a big challenge in profitable NDICs rearing in Bangladesh and warrants immediate attention for their control.

期刊介绍： First self-published in 1921, Poultry Science is an internationally renowned monthly journal, known as the authoritative source for a broad range of poultry information and high-caliber research. The journal plays a pivotal role in the dissemination of preeminent poultry-related knowledge across all disciplines. As of January 2020, Poultry Science will become an Open Access journal with no subscription charges, meaning authors who publish here can make their research immediately, permanently, and freely accessible worldwide while retaining copyright to their work. Papers submitted for publication after October 1, 2019 will be published as Open Access papers. An international journal, Poultry Science publishes original papers, research notes, symposium papers, and reviews of basic science as applied to poultry. This authoritative source of poultry information is consistently ranked by ISI Impact Factor as one of the top 10 agriculture, dairy and animal science journals to deliver high-caliber research. Currently it is the highest-ranked (by Impact Factor and Eigenfactor) journal dedicated to publishing poultry research. Subject areas include breeding, genetics, education, production, management, environment, health, behavior, welfare, immunology, molecular biology, metabolism, nutrition, physiology, reproduction, processing, and products.
