Cards Term How is Sleepy Foal Disease controlled? (Actinobacillus equuli) Definition Good sanitation and parturition. Term Actinobacillus equuli Definition "Sleepy Foal Disease" Naturally present in tonsils & intestines; only causes disease when predisposed by stress; may cause septicemia or purulent infections of joints and kidneys. Term Actinobacillus lignieresii Definition Affects cattle and sheep. Enters oral cavity through wounds in buccal mucosa; causes wooden tongue in cattle. Term Actinobacillus spp. Definition Gram neg. rods; both pleomorphic & filamentous; fac. anaerobic; indole neg.; urease pos. Term ***Taylorella (Haemophilus) equigenitalis Definition Contagious equine metritis; transmitted by stallion or fomites; profuse, grayish-white, mucopurulent vulvar discharge w/ endometritis, cervicitis, or vaginitis 2-12 days after breeding; decreased fertility in mares; stallions are asymptomatic carriers. Term Haemophilus gallinarum Definition Causes fowl coryza; respiratory transmission or through contaminated drinking water; nasal discharge, sneezing, facial swelling. Term Actinobacillus (Haemophilus) pleuropneumoniae Definition Swine; contagious pleuropneumonia; respiratory transmission; usually introduced or spread by imported affected animals. Term Haemophilus suis Definition SWINE; causes flu-like symptoms; swollen joints, lameness; fever; anorexia; depression. Term Haemophilus somnus Definition CATTLE; grows best in 5-10% CO2; causes TEME in cattle; sleepiness; fever of 107.6F; neurologic signs (stupor, ataxia, paralysis) Term Haemophilus spp. Definition Gram neg. rods or coccobacilli (small); non-motile; microaerophilic or fac. anaerobic. Predisposing factors: shipping stress, changes in climate, crowding. Term Contributing stress factors of shipping fever: Definition transportation; exhaustion; starvation; dehydration; chilling; overheating; exposure to exhaust fumes Term Causative factors of shipping fever: Definition Pasteurella hemolytica; Pasteurella multocida; viral infection; Parainfluenza 3; bovine respiratory synctial virus; mycoplasma. Term Pasteurella multocida Definition Gram neg. coccobacillus; non-hemolytic on BAP; rarely grows on MacConkey; catalase pos.; indole pos.; urease neg.; snuffles in rabbits; shipping fever in cattle. Term Prevention and control of Pasteurella hemolytica: (7 things) Definition minimizing stress; pre-conditioning programs; prophylactic drugs after shipping; early ID of sick animals w/ aggressive treatment to prevent losses; isolation of new herd members; good husbandry; ventilation; vaccination. Term Pasteurella hemolytica Definition Gram neg. coccobacillus; Biotype A colonies are gray w/ hemolysis on blood agar; Biotype B colonies have brownish centers and are hemolytic; MacConkey produces small pink colonies. Term Pasteurella spp. Definition Gram neg. coccobacilli or rod (small); aerobic or fac. anaerobic; catalase pos.; oxidase pos., indole neg. Term Proteus mirabilis Definition Gram neg. rod; motile; urease pos.; BAP: swarms, uniform film over entire agar. MacConkey: colorless. Distinct, putrid odor. Term Klebsiella pneumoniae Definition Gram neg. rod; non-spore forming, heavy capsule; non-motile. BAP: moist, spreading, glistening, viscid colonies, gray & nondescriptive; citrate pos., urease pos. Term Salmonellosis Definition Two forms: Septic: young animals; generally no diarrhea; high fever, elevated RR; elevated HR; neuro signs. Enteric: older animals; severe watery diarrhea; feces: putrid odor. Term Salmonella spp. Definition Gram neg. rod; motile; aerobic or fac. anaerobic; differential & selective media for ID; fecal/oral transmission of organism; MacConkey agar-colorless colonies; BAP-smooth, glossy surface with regular edge, or rough granular surface with irregular edge; Brilliant green agar-bright pink colonies; Bismuth sulfite-blue/green colonies w/ black centers. Term Control of E. coli (3 things) Definition ensure good colostrum intake; proper housing & good hygiene; vaccinating susceptible animals Term Escherichia coli Definition Gram neg. rod; non-spore forming; aerobic or fac. anaerobic; mostly motile; produces deep red colonies on MacConkey agar. Term Enterobacteriaceae Definition Gram neg. rods or coccobacilli (small); aerobic or fac. anaerobic; catalase pos.; oxidase neg.; variable motility; transmitted by naval infections, ingestion of contaminated feces; BAP-raised, smooth, glistening, gray, circular in outline.
