This review illustrates the concepts of enteropathy and immune expulsion, and discusses the implications of this for understanding the process of immune expulsion of gut nematodes and the prospects for anti-nematode vaccines. The pathology of nematode infections and nematode expulsion are...

This article describes the major routes by which water becomes contaminated with enteric pathogens and reviews human pathophysiology, animal reservoirs, presence and survival in the environment, and survival in water of major enteric pathogens (Campylobacter, Listeria monocytogenes, Escherichia...

Early ultrastructural observations of Cryptosporidium parvum-infected cells consistently described the accumulation of microfilaments beneath the dense band, suggesting the initiation of actin reorganization within the host cell. Immunolocalization and forced expression of β-actin green fluorescent ...

This chapter elaborates on pathogenic processes responsible for the production of symptoms during giardiasis and cryptosporidiosis. To date, research findings indicate that both infections share a number of these processes. Infection appears to cause diarrhoea via a combination of intestinal...

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 - our assessment of how animals...

This book chapter discusses the prevalence, geographical distribution, host range, disease transmission, diagnosis, clinical aspects, animal pathology, pathological lesions, pathophysiology, disease prevention, and control programmes against Neoparamoeba perurans in fishes.

This book chapter discusses the life cycle, animal pathology, host range, diagnosis, pathological lesions, pathophysiology, disease prevention and control programmes against Amyloodinium ocellatum in fishes.

This chapter covers the biology, morphology, transmission and impacts of Cryptobia salmositica infection. The diagnosis, clinical signs, histopathology, physiopathology, control and prevention (antiserum, monoclonal antibodies, disease resistance, vaccination, drug therapy, immunochemotherapy and...

This chapter gives an overview of the biology (life cycle, parasite stages, transmission and geographical distribution) and diagnosis of Ichthyophthirius multifiliis, host physiopathology and immunity as well as treatment and prevention of infection.

This chapter covers Miamiensis avidus and related species parasitizing fish and other aquacultured species. Focus is given on the tissue and geographical distribution, host range, transmission, impact on fish production, diagnosis, external and internal lesions, histopathology, physiopathology and...
