This chapter introduces plotting line graphs, bar charts, pie charts, box and whisker plots. It will troubleshoot the main areas where you are likely to encounter problems. It will show how to create log plots, add legends, error bars, notches and confidence limits, and introduce confidence limits...

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 gives an overview about: ruminants as final hosts; life cycle; Oribatid mites as intermediate hosts for Moniezia species; pathogenicity of Moniezia infections; experimental infections; responses to differential anthelmintic treatment; diagnosis; control of Moniezia species in sheep and ...

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 ...

This book chapter discusses liver flukes (Fasciola hepatica) and their snail intermediate hosts (Galba truncatula, Lymnaea auricularia), its molluscan intermediate hosts, G. truncatula habitats, snail movement, survival under unfavourable conditions, developmental stages, infection of the...

This book chapter discusses three main aims of grazing management as a means of controlling nematode and trematode populations and limiting their impact on their hosts, namely: to limit the acquisition of infective stages (larvae and metacercariae) by susceptible hosts in order to reduce the...

This book chapter discusses various perspectives for the control of endemic parasites on livestock farms, namely: to ensure that animal welfare is not adversely affected; this is a moral priority that is supported by legislation in most countries, allow animals to perform at a level that is...

This chapter includes questions and answers on the causes and signs of flea infestation of dogs and cats, whether fleas can kill, effect of grooming, why fleas bite, how to spot a flea, how to determine if a dog or cat has fleas, the difference of fleas with lice and ticks, how to take fleas off a...

This chapter analyses the interactions between the various elements (agent, transmission, host and environment) of communicable diseases. The force of infection and epidemic theory are discussed. Epidemics and how they are investigated and measured are described. Investigation of foodborne and...
