contagious disease
an airborne disease is any disease that is caused by pathogens that can be transmitted through the air. such diseases include many of considerable importance both in human and veterinary medicine. the relevant pathogens may be viruses, bacteria, or fungi, and they may be spread through breathing, talking, coughing, sneezing, raising of dust, spraying of liquids, toilet flushing or any activities which generates aerosol particles or droplets. human airborne diseases do not include conditions caused by air pollution such as volatile organic compounds (vocs), gases and any airborne particles, though their study and prevention may help inform the science of airborne disease transmission.

"borrelia" bacteria are well described elsewhere in association with "ixodes" ticks for causing lyme disease in humans, but this disease also affects domestic dogs. "borrelia anserina" is transmitted by "argas persicus" to poultry, causing avian borreliosis in a wide spread of tropical and subtropical countries. "anaplasma phagocytophilum" (formerly "ehrlichia phagocytophila") is a bacterium of deer that spreads to sheep where it causes tick-borne fever in europe, resulting in abortion by ewes and temporary sterility of rams. this bacterium invades and proliferates in neutrophil cells of the blood. this depletes these antibacterial cells and renders the host susceptible to opportunistic infections by "staphylococcus aureus" bacteria which invade joints and cause the crippling disease of sheep called tick pyaemia. "anaplasma marginale" infects marginal areas of red blood cells of cattle and causes anaplasmosis wherever boophilid ticks occur as transmitters. "anaplasma centrale" tends to infect the central region of red blood cells, and is sufficiently closely related to "an. marginale" to have been used from long ago as a live vaccine to protect cattle against the more virulent "an. marginale". sheep and goats suffer disease from infection with "anaplasma ovis" which is transmitted similarly to the anaplasmas described above. "ehrlichia ruminantium" (formerly "cowdria ruminantium") is transmitted mainly by "amblyomma hebraeum" and "am. variegatum" in africa, causing the severe disease heartwater in cattle, sheep, and goats. this disease is named after the prominent sign of pericardial edema. the bacteria infect the brain, causing prostration. heartwater also occurs on the caribbean islands, having spread there on shipments of cattle from africa about 150 years ago, before anything was known of tick transmitted microbes.
