GERM GLOSSARY

Anthrax: An infectious disease of warm-blooded animals - as cattle and sheep - caused by a spore-forming bacterium transmissible from animals to man, especially by the handling of infected animal products and characterized by external ulcerating nodules or by lesions in the lungs.

Aspergillus fumigatus: A fungus growing in soils and manure. It has been found in the ear, nose and lungs. Aspergillosis in humans usually occurs in agricultural workers, hair or fur cleaners and others exposed to inhalation of spores. It is characterized by formations of lumps in the skin, ears, sinuses and respiratory organs.Bacillus: Any of a genus of rod-shaped bacteria that occur in chains, produce spores and are active only in the presence of oxygen.

Bacillus anthracis: The causative agent of anthrax in lower animals and man.

Bacillus subtilis: A common soil and water form, often occurring as a laboratory contaminant, and in rare instances found in apparently causal relation to pathologic processes.

Botulism: A type of food poisoning caused by a toxin produced by the growth of Clostridium botulinum. Characterized by muscle weakness and paralysis, disturbances of vision, swallowing and speech, and marked by a high mortality rate.

Brucella suis: Found primarily in swine, this capable of producing severe disease in man.

Brucella melitensis: The causative agent of classic Malta fever (undulant fever). It occurs primarily - but not exclusively - in goats as the carrier of infection.

Brucellosis: Also called Malta fever or undulant fever. Undulant fever is a persistent form of brucellosis, which is transmitted to man by contact with lower animals - especially domestic animals - or their products or from the consumption of the milk, dairy products or meat from infected animals. It is characterized by great weakness, extreme exhaustion on slight effort, night sweats, chilliness, remittent feaver and generalized aches and pains.

Clostridium botulinum: The agent causing botulism in man, limberneck in chickens, botulism in wild ducks and forage poisoning in cattle. It is nearly cosmopolitan in soil, animal intestines and dung.

Coccidiosis: Various diseases of domestic animals, birds and - in rare instances - man. It is caused by members of an order of sporozoans living as parasites in the intestines.

Coxiella burnetii: The etioloic agent of Q fever. It is transmitted by ticks and also acquired by inhalation of infectious dust and other materials from infected animals.

Q fever: So named because of the many unanswered questions about the disease when first identified. Q fever is characterized by fever, headache, muscular pains and pneumonia.

Pasteurella: A genus of bacteria that includes several important pathogens of man and domestic animals, including hemorrhagic septicemia, plague and tularemia.

Pasteurella tularensis: The etiologic agent of tularemia in man, being transmitted from wild animals to man by drinking water, by blood-sucking insects or by contact.

Pasteurella pestis: The etiologic agent of plague in man and rats, ground squirrels and other rodents, transmitted by the rat flea and the human body louse.

Psittacosis: A virus disease first observed in parrots and known to be communicated by them to man. It also exists in other birds and domestic fowl. In humans, the disease is characterized by fever and pneumonia.

Tularemia: An infectious disease of rodents - especially rabbits - caused by Pasteurella tularenis and transmitted to man in handling the flesh of infected animals or by the bite of certain insects. It is characterized by an irregular fever, aching, inflammation of the lymph glands.

Wheat rust, wheat stem rust: Any of three destructive diseases of wheat caused by rust fungi.
