6/9 Flashcards
Non host specific salmonella in pigs
s. choleraesuis: typhoid
s. typhimurium
food safety
most frequently sub clinical
diarrhea + general symptoms
slow spread consistent
hyperacture and acute in older pigs- cyanosis
chronic form- smaller pig- behind in growth rate
carriers
salmonella in pig dx
bacterial culture
ELISA - Ag - Cheaper and Faster
ELISA - Ab (control programs)
Tx of salmonella in pigs
antibiotics, general support in acute NSAIDs
Px of salmonella in pigs
Mgmt AI-AO cleaning and disinfectant. Supplement feed with organic acids, short chain fatty acids, in feed or drinking water . Want in ileum and large intestine to lower ph. Feed composition- particle size: influence stomach ph. Want it to be lower. have been working on a vax for a few years but didnt work still in developement.
typhoid salmonella in horses
salmonella abortus - uptake dependent
per os salmonella in horses
septicemia: endotoxic shock
venereal salmonella in horses
invasize, polyarthritis
stallion salmonella in horses
reduced fertility
mare salmonella in horses
abortion, live foals acute mortality, polyarthritis, persistent infections ( intracellular) several abortions septicemic foals
salmonella in horses DX, TX
bacteriology, antimicrobials , elimination from repro organs is difficult
Non specific salmonella in horses
short incubation period, clinical problems mild (fever anorexia depression possible diarrhea) very acute. Mortality. hyperacute: septicemic (endotoxic shock). Chronic: source of infection
DX : difficult: isolation from feces frequently unsuccessful)
Acute form nonspecific salmonella in horses
fever anorexia mild colic severe symtoms with cyanosis (blue mm) gram - = LPS shock. laminitis after recovery. Slow recovery and relapse. Can evolve to chronic (intracellular) intermittent diarrhea anorexia weight reduction
hyperacute nonspecific salmonella in horses
only foals (immunity less developed) severe general symptoms eventual diarrhea endotoxic shock with death in 24 to 72 hours. if they survive tissue localization- often arthritis
nonsalmonella in horses dx, therapy
Neutropenia
HYDRATE! Shock : NSAIDS….NO CORTICOS= laminitis. Antimicrobials, be careful of carriers.
Salmonella in cats and dogs: nonspecific host
enteritis and septicemia. origin: feed. dx:culture, ELISA (Ag), PCR tx: hydration Antibiotics careful, may become carriers, may contaminate the house. Be wary of clients with children.
Salmonella in Pigeons: paratyphus
S. typhimurium var. Copenhagen septicemia not zoonotic carriers cause of spread chronic: one wing hanging down, intermittent excretion
salmonella psitaciformes and passeriformes
in birdhouses. stress overcrowding outside. inappropriate feeding. 2ndary triggers
Salmonella in Poulty
typoid- s. pullorum, s. gallinarum
non typhoid- s.enteriditis ( many other serotypes)
antigenically similar
poultry vs pigs salmonella - acquiring infection from meat
difficult to butcher poultry in a clean way. higher chance of getting inf from poultry meat.
S. pullorum
Pullorum dz
chicken turkey pheasant
S. gallinarum
chickens ducks pheasant quail turkey
older animals
hyperacute
high mortality
S. enterica ssp. arizonae
TURKEYS mainly in the USA only younger animals different serotypes mortality up to 50% Dx:culture treatment: best to eradicate control by serology: difficult, false negatives
S.enteriditis
Zoonotic
consumption of undercooked raw egg (mainly in egg white)
on carcass
vax in europe
__% of chickens are positive for Salmonella
30% ( increases after defeathering at slaughter)
Equine meteritis
Klebsiella- vaginitis infertility abortion
stallion fomites veterinarians
umilical inf in foals- assoc with not enough colostrum
uterine wash
resistant to amoxy and ampi
high level of acquired resistance
Klebsiella dogs
pyometra- rare
