24
Q

The predominant streptococcal disease in swine is caused by ________________________ and is usually seen in nursing or recently weaned pigs

A

streptococcus suis (most common)

25
This disease is characterized by septicemia, acute meningitis, polyarthritis and brnchopneumonia
streptococcal infection: streptococcus suis
26
T/F streptococcus suis (most common) is zooinotic
TRUE occurs occasionally in people who work with pigs or handle meat caused localized infections, arthritis, septicemia and even death
27
does streptococcus suis have a high mortality rate in pigs
YES
28
symptoms of streptococcal infection
stretched out on side paddling tremors blindness swollen joints lameness
29
prevention of streptococcal infection
vaccine biosecurity
30
treatment for streptococcal infection
antibiotics ** some strains are resistant to antibiotics (NOT EFFECTIVE once CNS is involved/shot)
31
transmission of streptococcal infection
oral nasal (passes through the tonsils) secretions (gets into wounds) vecto (fly=5days)
32
streptococcus suis survives in ______ and _______ in the pigs environment
dust feces
33
This causes inflammation of the tissues and turbinate bones of the snout inside the nasal passageway turbinate bones in the snout become damaged resulting in shrinkage or distortion
atrophic rhinitis
34
what are the two forms of atrophic rhinitis
mild, non-progressive (common) Progression (PAR) **VERY SERIOUS**
35
what causes atrophic rhinitis
poor ventilation dusty atmosphere low humidity high bacterial counts in the air high levels or aerosols/ammonia PRRS
36
symptoms of atrophic rhinitis
MILD: sneezing and nasal discharge PAR: bloody nose, disfigured snout, tear-stained face, difficulty eating
37
prevention for atrophic rhinitis
Vaccine if it is prevalent in herd **most don't vaccinate because it isn't financially necessary
38
treatment for atrophic rhinitis
antibiotics
39
infectious disease of growing and mature swine, zoonotic and causes Erysipeloid in humans
Erysipelas Bacteria is always present in swine or the environment.
40
a localized skin infection that occurs in people who work with infected animals, processed meats, or animal by-products
Erysipeloid
41
transmission of Erysipelas
secretion (fecal and nasal) contaminated feed and water
42
symptoms of Erysipelas
really high fever (104-108) reddening or cyanotic skin small raised diamond/square rash that is red then turns black swollen joints repro failure
43
prevention of Erysipelas
vaccination biosecurity quarantine new animals
44
treatment for Erysipelas
antibiotics (penicillin)
45
erosion and ulceration of the lining of the stomach common in all pigs
gastric ulcers
46
Gastric ulcers can lead to ____________ which can lead to anemia/death
hemorrhaging
47
in growing pigs,_______% show gastric ulcers at slaughter
60%
48
What causes gastric ulcers in swine
diet composition size of feed particles ** common reason irregular feed temp fluctuating high stock rates stress
49
what kind of feed can cause ulcers
too fine in size low protein low fiber high energy more than 55% wheat high mineral content low zinc, vitamin E and selenim
50
symptoms of gastric ulcers
pale grinding teeth dark feces (blood) vomiting diarrhea
51
treatment for gastric ulcers
feed highly digestable materials (whey, coarse grain) vitamin E injections
52
____________ are most often a result of cold stress (piling for warmth), transportation stress, severe coughing, or constipation
rectal prolapses
53
examples of diets that can cause rectal prolapses
high levels of whey DDGS low fiber
54
treatment for rectal prolapse
surgical amputation rectal tubes **if in a replacement gilt=cull
55
what kind of pigs often exhibit atrophic rhinitis
outdoor pigs
56
what are the zoonotic diseases we talked about
swine flu lepto ringworm erysipelas
