There are many (>30) species of gastrointestinal nematodes that have been recorded as parasites of sheep; however, relatively few species contribute commonly and significantly to parasitic gastroenteritis (PGE), of which four genera play major roles: Teladorsagia, Trichostrongylus, Haemonchus...

This chapter focuses on haemonchosis and nematodirosis in sheep in temperate regions. Subject headings are: parasite biology, pathology and pathophysiology; coinfections among abomasal nematodes; clinical observations; host responses; nutritional influences; periparturient period; larval ecology;...

This chapter describes the biology, clinical signs, pathology, larval ecology, immunity, epidemiology and control of the large ovine lungworm Dictyocaulus filaria. The parasitic stages in the host, clinical signs, free-living stages and intermediate molluscan hosts, transmission of infective larvae ...

The clinical signs, diagnosis and treatment of ectoparasitic skin diseases in horses are described.

This chapter discusses the aetiology, clinical features, diagnosis, transmission, incubation period, period of communicability, occurrence and distribution, control and prevention (e.g., hygiene, sanitation, vaccination, safe water supply), treatment (e.g., oral rehydration, drug therapy) and...

This chapter discusses the aetiology, clinical features, diagnosis, transmission, incubation period, period of communicability, occurrence and distribution, control and prevention, treatment (e.g., fluid/electrolyte replacement, oral rehydration, drug therapy) and surveillance of food poisoning, ...

This chapter discusses the aetiology, clinical features, diagnosis, transmission, incubation period, period of communicability, occurrence and distribution, control and prevention, treatment and surveillance of water-borne diseases such as schistosomiasis, guinea worm (Dracunculus medinensis) and...

This chapter describes the 2 main groups of disease-transmitting mosquitoes (anophelines and culicines) and arbovirus infections grouped into 3 symptom complexes: those producing mainly fever or arthritis (Chikungunya, O'nyong-nyong, West Nile, Orungo, Oropouche and Ross River fevers and Zika);...

This chapter describes the risk factors, epidemiology, prevalence, distribution, transmission, pathogenesis, clinical signs, diagnosis, treatment, prevention and control of rabies, hydatid disease, toxocariasis, larva migrans, toxoplasmosis, brucellosis, anthrax, leptospirosis and Lassa fever in...
