The use of diagnostic methods for the diagnosis of parasitic diseases in poultry has been almost constant over the past few decades. Since the introduction of PCR, few major advances have been adopted in clinical diagnostic tests. Many diagnostic tests that form the backbone of the “modern” microbiology laboratories rely on very old and labour-intensive technologies such as microscopy for the diagnosis of parasites including helminths, protozoans, arthropods, and haemoprotozoans. Urgent needs include more rapid tests without compromising the sensitivity, value-added tests, and point-of-care tests for both high- and low-resource settings. In recent years, research has been focused on alternative methods to improve the diagnosis of parasitic diseases. These include molecular technique-based approaches, immunoassays and proteomics using mass spectrometry platforms technology. This chapter discusses the progress of several approaches in parasite diagnosis and some of their silent characteristics. © 2025, Bentham Books imprint.
Protozoan Parasitic Infection
(Bentham Science Publishers, 2025) R. L. Rakesh; S. Kumar; Pradeep Kumar; Alok Kumar Singh; Souti Prasad Sarkhel; Anupam Brahma; Vivek Agarwal
Poultry has protozoa that are classified into multiple taxonomic groupings. In poultry, two types of parasites are significant: the coccidia and the mastiogophora (flagellates). Some parasites, which cause coccidiosis, have short, direct life cycles and are therefore preferred, while other parasites that involve intermediate hosts typically do not pose a threat to commercial poultry. A significant exception is blackhead disease (histomoniasis), which has a complex life cycle involving intermediate hosts, but relies on chickens as reservoir hosts and spreads easily among turkeys within a flock. Most coccidia found in poultry belong to the genus Eimeria, however, there are also some species of Isospora and Cryptosporidium. The most well-known are the Eimeria, of which seven significant species have been identified in chickens and several more in turkeys. Anywhere chickens are raised, whether in huge commercial operations or tiny backyard flocks, parasites are an issue that can result in severe financial losses. This chapter will provide a quick overview of the main poultry protozoan parasitic species, along with some pathophysiology. © 2025, Bentham Books imprint.
