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 book chapter describes the pathology (prehepatic stages, hepatic stages, other host species), clinical aspects, effects on blood components, pathophysiology and metabolic aspects, effects on metabolism, and pathogenesis of Fasciola infection.

This chapter describes the risk factors, aetiology, clinical signs, pathology, treatment, prevention and control of bacterial, viral, fungal, protozoal and parasitic diseases of pheasants and partridges raised as game birds in the UK.

This book chapter describes various aspects of microsporidiosis caused by Loma salmonae: diagnosis, life cycle, influence of water temperature, host range, geographic range, pathobiology and physiopathology, clinical pathology, control and prevention, and recommendations for future studies.

This chapter describes the different pathways of disease transmission, risk factors, prepatent period, pathogenesis and clinical signs of infectious diseases in domestic animals.

Health and disease are important components in the broader concept of welfare. Understanding the relationship between health and welfare requires inferences about subjective feelings such as pain and distress. Similar types of disease occur in animals and humans, and our assessment of how animals...

This chapter covers the host range and specificity, morphology, life cycle, physiopathology, parasite-host interactions, role as disease vector and control and prevention (biological control, environmental approach, drug therapy, vaccination and insecticides) of Lepeophtheirus salmonis and Caligus...

The morphology, host range, epidemiology, diagnosis, clinical signs, macroscopic and microscopic lesions, physiopathology and control and prevention of Argulus foliaceus are covered in this chapter.

This chapter covers the general biology and distribution (systematics, life cycle and epidemiology) of Anguillicoloides crassus. The diagnosis, macroscopic and microscopic lesions, pathobiology (mortality, condition, swimming performance and reproduction) and control and prevention (drug therapy,...
