Respiratory diseases of swine cause major economic losses. In many cases, respiratory disease losses are not recognized because death losses are low and reduced feed efficiencies are the primary effect. The major infectious organisms currently associated with swine pneumonias are Mycoplasma hyopneumoniae, Pasteurella multocida, Bordetella bronchiseptica, Hemophilus pleuropneumoniae, Hemophilus ...

Congenital defects or diseases are abnormalities of structure or function present at birth. In cattle many of these defects of either genetic, environmental, or unknown cause—or due to environmental-genetic interaction—have been identified. The genetically caused diseases are mostly due to homozygosity of a simple autosomal recessive gene, meaning that the animal has received one defective gene...

This chapter provides brief descriptions of diseases that 1) more commonly are found in small, backyard poultry flocks, or 2) are more significant economically or personally when they do occur. Further reading on these and many other diseases is recommended. All Poultry Types. Two important diseases shared by chickens, turkeys, guinea fowl, partridges, pheasants, quail, and domestic waterfowl (...

Nanotechnology, as a new enabling technology, has the potential to revolutionise agriculture and food systems in the United States of America and throughout the world. Examples of potential applications of nanotechnology in the science and engineering of agriculture and food systems include disease treatment delivery systems, new tools for molecular and cellular biology, the security of agricul...

Lyme disease is induced by the spirochete B. burgdorferi. Spirochetes are transmitted to horses by infected ticks. Similar to humans, horses are incidental, dead-end hosts for B. burgdorferi 1. Not all infected horses develop clinical signs of Lyme disease. If clinical signs occur, they can include chronic weight loss, sporadic lameness, shifting leg lameness, low-grade fever, muscle tenderness...
