neverforgetparasit

If you suspect lung worms or other parasites that migrate through the lungs

23
Q

What are three fungal infections that will present at primary lung disease with the addition of skin lesions?

A 
Blastomyces dermatitidis
Histoplasma capsulatum (causes HGE in dogs)
Coccidioides immitis (osteomyelitis)
24
Q

What geographic location will you find coccidioides immitis?

A

South west US - San Joaquin valley

25
Q

What geographic locations will you find histoplasma capsulatum?

A

Ohio, Missouri, and Mississippi river valleys of the US

26
Q

What geographic location can you find blastomyces dermatitidis?

A

Ohio-Mississippi river valley of North America

27
Q

What geographic locations can you find crytococcus?

A

Anywhere pigeons or eucalyptus trees are prevalent

28
Q

T/F: Shipping fever always has multifactorial etiology

A

TRUE

29
Q

Which is the most important bacterial agent in the bovine respiratory disease complex and what is its virulence factors?

A

Mannheimia haemolytica

**secretes a specific ruminant leukotoxin - attacks the neutrophils

*can note oblong shaped neutrophils on cyto that have been affected by the leukotoxin

30
Q

What bacteria caused NECROTIC laryngitits in calves?

What bacteria causes laryngitis in cattle?

A

Necrotic laryngitis aka calf diptheria = Fusobacterium necrophorum

Histophilus somni = laryngitis in cattle (part of the shipping fever complex)

31
Q

What three bacteria are involved in enzootic pneumonia in calves?

A

Pasteurella multocida
Mannheimia haemolytica
mycoplasma bovis

32
Q

Contagious bovine pleuropneumonia is caused by what bacteria?

A

Mycoplasma mycoides subsp mycoides (small colony type)

*marbled lung

**REPORTABLE

33
Q

Contagious caprine pleuropneumonia is caused by what bacteria?

A

Mycoplasma capricolum subsp capripneumoniae

**reportable

34
Q

Mycoplasma bovis causes what there types of dz in cattle?

A

Pneumonia
Mastitis
Arthritis

35
Q

T/F: Enzootic pneumonia in calves has a high morbidity due to fast spreading dz

A

TRUE

36
Q

What role does colostrum play in the cases of enzootic pneumonia?

A

If calves do not get enough or good quality colostrum they do not get maternal protection and this leaves them very susceptible to infection

37
Q

What viral infections predispose calves to enzootic pneumonia?

A

Bovine herpes virus
Bovine diarrhea virus
Parainfluenza
BRSV

38
Q

What are the common pathogens that cause enzootic pneumonia in calves?

A

Pasteurella multocida
Mannheimia haemolytica
Mycoplasma bovis

39
Q

What bacteria causes a characteristic marbling effect on the lungs of cattle?

A

Mycoplasma mycoides subsp. mycoides

Contagious Bovine Pleuropneumonia

**REPORTABLE

40
Q

T/F: Pasturealla multocida serotypes B1 and E2 cause hemorrhagic septacaemia in cattle in the US

A

FALSE

not present in the US. These strains are common in Asia

41
Q

Why must you send a large tissue sample for culture if it is collected at necropsy?

A

So the lab can test a sample from the center that should be free from contamination

42
Q

What bacteria causes Tularemia?

A

Francisella tularensis

43
Q

What is the main sentinel domestic animal that will get infected with francisella tularensis?

A

CATS

also rabbits, and rodent

***ZOONOTIC/BSL3/REPORTABLE

vector borne

44
Q

Who are the main carries of Yersinia pestis?

A

Rat fleas

45
Q

Why are rat fleas the specific vectors for yersinia pestis and not cat or dog fleas?

A

Dog and cat fleas have a poor ability to become blocked.

Rat fleas with yersinia pestis will have a biofilm formation in the proventriculus (mixture of blood clot and bacteria) - this will inhibit the flea from feeding. As it attempts to feed, ingested blood will go into the esophagus - contact the biofilm and then be regurgitated back into the circulatory system of the host with bacteria from the biofilm

46
Q

What pathogens cause atrophic rhinitis in swine?

A

Pasteurella multocida

Bordetella bronchiseptica

47
Q

What are the toxins associated with atrophic rhinitis in swine and what do they effect?

A

Pasteurella multocida toxin –> osteoclasts

Bordetella bronchiseptica dermonecrotic toxin –> osteoblasts

48
Q

Glasser’s disease is caused by what pathogen, who is the host?

A

Haemophilus parasuis - swine

Polyserositis, polysynovitis, meningitis, systemic infection and DIC

49
Q

What is the pathogen that causes Porcine pleuropnemonia?

A

Actinobacillus pleuroprneumonia

**hemorrhagic and necrotizing pleuropneumonia

50
Q

What two pathogens have leukotoxins that destroy white blood cells?

A

Actinobacillus pleuropneumoniae (swine)

Mannheinemia haemolytica (**ruminant specific leukotoxin)

51
Q

What pathogen causes foal pneumonia?

A

Rhodococcus equi
(foals 1-4months old)
*pyogranulomatous lesions in the lung

*gram positive coccobacilli - faculatative intracellular

52
Q

T/F: Rhodococcus equi has some acid fast positive staining

A

TRUE

53
Q

T/F: Glanders and Pseudoglanders are diseases that may have lung involvement

A

TRUE

54
Q

Which pathogen is obligate and which pathogen is saprophytic?

Burkholderia mallei
Burkholderia pseudomallei

A

Burkholderia mallei is an obligate pathogen of horses
