PasteurellosisElaeophora schneideri: Elaeophora schneideri (arterial worm; cause of elaeophorosis, aka "filarial dermatitis" or "sorehead" in sheep; or "clear-eyed" blindness in elk) is a nematode which infests several mammalian hosts in North America. It is transmitted by horse-flies.Pasteurella multocida: Pasteurella multocida is a Gram-negative, nonmotile, penicillin-sensitive coccobacillus belonging to the Pasteurellaceae family. Strains belonging to the species are currently classified into five serogroups (A, B, D, E, F) based on capsular composition and 16 somatic serovars (1-16).Pasteurellaceae: The Pasteurellaceae comprise a large family of Gram-negative bacteria. Most members live as commensals on mucosal surfaces of birds and mammals, especially in the upper respiratory tract.Pseudomonas exotoxin: The Pseudomonas exotoxin (or exotoxin A) is an exotoxin produced by Pseudomonas aeruginosa.Beef cattle: Beef cattle are cattle raised for meat production (as distinguished from dairy cattle, used for milk production). The meat of adult cattle is known as beef.MastitisBacterial pneumoniaCorriedale: Corriedale sheep are a dual purpose breed, meaning they are used both in the production of wool and meat. The Corriedale is the oldest of all the crossbred breeds, a Merino-Lincoln cross developed almost simultaneously in Australia and New ZealandStock Types, The Land, North Richmond, c.Immunization during pregnancy: Immunization during pregnancy, that is the administration of a vaccine to a pregnant woman, is not a routine event as it is generally preferred to administer vaccines either prior to conception or in the postpartum period. When widespread vaccination is used, the risk for an unvaccinated pregnant patient to be exposed to a related infection is low, allowing for postponement, in general, of routine vaccinations to the postpartum period.Lung receptor: Lung receptors sense irritation or inflammation in the bronchi and alveoli.BronchopneumoniaBacterial outer membranePasteurella dagmatis: Pasteurella dagmatis is a Gram-negative, nonmotile, penicillin-sensitive coccobacillus belonging to the Pasteurellaceae family. Bacteria from this family cause zoonotic infections in humans.
