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;...

Large lungworms can cause clinical disease and occasional mortality, whereas infections with small lungworms are often subclinical. Although several species of small lungworm have been isolated from small ruminants, this book chapter describes the most commonly described in the scientific...

This chapter describes the role of genetics on disease resistance and susceptibility, inbreeding, genetic diversity and other complex traits in horses.

This chapter describes the history, use and efficacy of the different types of vaccines against Mycobacterium avium subsp. paratuberculosis in animals.

This article describes the history, development and efficacy of the different types of vaccines against Mycobacterium avium subsp. paratuberculosis.

This chapter defines communicable disease and discusses its agents, transmission patterns, host factors (susceptibility, inherent defence mechanisms, immunity and resistance), and impact of social environment (education, resources, economics, communities and movements) and physical environment...

The levels of disease caused by a particular pathogen species on its host plant can vary considerably. This has both fascinated plant pathologists and been exploited by plant pathologists and plant breeders for over a century. Different isolates of the pathogen can be more or less aggressive, and...

This chapter presents research findings on the genetics of susceptibility of domestic ruminants to Mycobacterium avium subsp. paratuberculosis infection.

This chapter describes the epidemiology, prevalence, distribution, risk factors, transmission, immunology, clinical signs, diagnosis, treatment, prevention and control of Mycobacterium avium subsp. paratuberculosis in goats are described.

This chapter describes the development of animal models to understand the pathogenesis of infection and disease and to test novel vaccine candidates for Mycobacterium avium subsp. paratuberculosis.
