Coccidiosis in Livestock,
Poultry, Companion
Animals, and Humans
Praise for the Book
Coccidiosis in Livestock, Poultry, Companion Animals, and Humans is a long needed update and review for this group
of clinically important protozoan parasites that infect a wide variety of hosts. It’s been 25 years since the coccidia were
thoroughly reviewed with updated information so it’s timely and needed. The group of internationally recognized authors
and subject matter experts have updated important aspects about Coccidiosis including detailed chapters on their biology,
phylogeny, immunity, vaccination, modern molecular biology techniques, anticoccidial drugs, and new information on the
coccidia of cattle. Coccidiosis in Livestock, Poultry, Companion Animals, and Humans will be a must have comprehensive
resource for a wide range of global scientific disciplines for upper level undergraduate and graduate students, and research-
ers that include veterinary parasitologists, veterinarians, physicians, clinicians, and animal and poultry scientists.

This book focuses on the genera Eimeria, Cyclospora and Cystisospora, which are apicomplexan parasites, known as
conventional coccidia, and cause coccidiosis. Coccidiosis is one of the most important diseases of livestock, particularly
poultry, but occurs also in many other farm and companion animals, as well as in humans. Coccidiosis has a huge economic
impact, and represents a constant threat to the food supply. The extensive use of coccidiostats, especially against Eimeria in
poultry, has led to widespread drug resistance, and this problem needs to be solved in the years to come, as there are many
challenges ahead in order to ensure food security, but also food safety, for an ever-growing population on this planet. A
plethora of studies on different aspects of coccidian biology, phylogeny, pathogenesis and treatment and prevention strate-
gies have been carried out and published during the last 20–30 years, and it has become difficult to keep track and maintain
an overview of the research developments in the field. Thus, this book summarizes in a concise and very structured manner
the current knowledge on coccidiosis caused by conventional coccidia, and as such fills an important gap.
The driving force behind this book has been Dr. Jitender P. Dubey, which is clearly one of the most eminent parasitolo-
gists on this planet, and also known for his excellent books on Toxoplasma, Cryptosporidium, Sarcocystis and Neospora.
Here, Dr. Dubey recruited scientists of high international reputation from all over the world to contribute chapters on the
basic biology of coccidia, phylogeny, host immunity, vaccination, genomics, transcriptomics and proteomics, and on the
current state of anti-coccidial drugs. These seven chapters provide an excellent and up-to-date overview on the covered
subjects. The following chapters are dedicated to coccidiosis in the different major livestock species, including cattle, water
buffaloes, pigs, sheep, goats, and most important, poultry. However, also other host species are covered, including camelids,
rabbits, turkeys, ducks, horse and other equids, dogs, cats, and also humans. In these chapters the reader will encounter
concise information on the different species of coccidia found in the different host species, the life cycle and morphological
features, data on prevalence, on the pathogenesis, diagnosis, management and treatment options.
The book also contains stunning illustrations, showing the morphological, histological and structural features of the
different coccidia, and how infections affect their hosts and cause disease. In addition, many tables are provided that sum-
marize all this information in a concise and clear manner. Overall, I believe that this book represents an invaluable, highly
useful resource and “must-have” for all interested in coccidian parasites, including students, biologists, veterinarians, para-
sitologists, government, academia and industry.
