Q

Parvo - Pathogenesis

A

Viral material is ingested and enters the blood stream through the Peyer’s patches and the lymphatic tissue in the mouth:

1) Oropharyngeal LN

2) GI Mesenteric LN. => Viremia => Bone marrow, Thymus, Lymph nodes (Destruction of lymphocytes and neutrophils)

2 Options from there:

1) Proliferation in the GI mucosa (Severe gastroenteritis - common) with risk of secondary bacterial translocation from the gut to the bloodstream - Sepsis

Proliferation in cardiomyocytes (Sudden death - rare)

Q

Parvo - How long does it take for clinical signs to manifest post-infection? When does the dog begin to secrete to virus?

A

Clinical signs begin 4 days post infection

Secretion of the virus - 3 days post infection

In other words - viral particle shedding begins BEFORE clinical signs!

60
Q

Feline Infectious Peritonitis (FIP) - Internal mutation hypothesis - Explain

A

FIP is originally FECV that undergoes mutation internally in individual cats - happens in <5% of FECV-infected cats. While FECV is infectious and is transmitted via an oro-fecal route - FIP is not considered infectious

61
Q

Feline Infectious Peritonitis (FIP) - What strain is infectious - FECV / FIP

A

FECV

62
Q

Feline Infectious Peritonitis (FIP) - Pathogenesis

A

Exposure to viral material - (Oro-nasal exposure) => Replication in tonsils and Small intestine => FECV => Gastroenteritis and mild diarrhea.

At a later stage FECV mutates to FIP:

Option A: Strong immune system destroys the virus => Healthy +- carrier state

Option B: Moderate immune reaction => Dry form (chronic disease): Infiltration of macrophages/monocytes => Formation of granulomas => Clinical signs vary and depend on the affected organs => Death

Option C: Weak immune reaction => Wet form (acute disease): Infiltration of macrophages/monocytes => Ascites/Pleural effusion => Death

63
Q

Feline Infectious Peritonitis (FIP) - Signalment

A

Young cats in multi-cat households - Incidence begins to rise after weaning and reaches peak at 6-18 months. Second peak: >10 years old

64
Q

Feline Infectious Peritonitis (FIP) - Mortality increases\decreases with age

A

Decreases. But another peak after the age of 10

65
Q

Feline Infectious Peritonitis (FIP) - Risk factors for infection

A

Multi-household cats

Stress

Weaning

Co-Infections (e.g. FeLV)

66
Q

Feline Infectious Peritonitis (FIP) - Wet form - Clinical signs

A

Fever

Anorexia\Normal\Increased appetite

Weight loss

Pale mucus membranes \ Cyanosis

Icterus

Dyspnea, Tachypnea

Pleural\Abdominal\Pericardial effusion

Uveitis

67
Q

Feline Infectious Peritonitis (FIP) - Dry form - Clinical signs

A

Varies - Depends on where the granulomas are formed (Kidney \ Liver \ Eye \ CNS \ GI \ Peritoneum)

68
Q

Feline Infectious Peritonitis (FIP) - Properties of the typical effusion collected in the wet form

A

Non-septic exudate

Protein-rich (>3.5 g\dL) with low cellularity

Yellowish-color with fibrin

Cytology - Predominantly activated macrophages and non-degenerate neutrophils.

69
Q

Feline Infectious Peritonitis (FIP) - What’s the name of the test performed on fluids to test if its rich in fibrin? Other DDs if positive results

A

Rivalta

Septic peritonitis

Lymphoma

70
Q

Feline Infectious Peritonitis (FIP) - Lab findings (Including CSF)

A

Leukocytosis: Neutrophilia + Lymphopenia

Mild non-regenerative anemia

Hyperbilirubinemia

Hyperglobulinemia

Hypoalbuminemia

CSF - Protein rich, Pleocytosis predominantly neutrophils

71
Q

Feline Infectious Peritonitis (FIP) - Serological tests are a viable option for diagnosis. Explain

A

No! Can’t differentiate between FIP and FECV based on serology. FIP diagnosis based on serology = Malpractice! Mainly assists in ruling out the disease.

72
Q

Feline Infectious Peritonitis (FIP) - PCR is a viable option for diagnosis. Explain

A

While PCR has increased likelihood for diagnosis (Better specificity than serology), FIP can have a variety of mutations that won’t be detected by PCR. One current diagnostic method is to send a sample of abdominal effusion for PCR that checks for a few of the most common mutations (by IDEXX).

73
Q

Feline Infectious Peritonitis (FIP) - Diagnosis - Gold standard

A

Histopathology \ Immunohistochemistry

PM - Fibrin deposition + granulomas on omentum and serosal surfaces in both wet & dry forms

74
Q

Feline Infectious Peritonitis (FIP) - Prognosis

A

Without specific treatment - Grave

Wet form - 8 Days MST from diagnosis

In recent years - new treatments have improved prognosis significantly

75
Q

Feline Infectious Peritonitis (FIP) - Treatment

A

Supportive:
Fluids
Anti-emetics
Appetite stimulant

Drain abdominal effusion - only if fluid accumulation is contributing to dyspnea - and only drain about 30% - to avoid worsening of hypoalbuminemia, Hypokalemia

Oxygen (in case of dyspnea)

*Several FIP-specific treatments have emerged in past years (e.g. GS-441, Remdesivir) that have shown remarkable results with complete recovery from what was once a fatal disease - including FIP with CNS involvement.

76
Q

Feline Infectious Peritonitis (FIP) - Prevention

A

Reduce crowding & and keep hygiene

77
Q

Feline Infectious Peritonitis (FIP) - Prevention - No vaccine available (T/F)

A

True

78
Q

Spirocercosis - Pathogenesis

A

Host beetle\Paratenic host is swallowed => Dissolves in the stomach => Worm migrates through gastric and coeliac artery walls => Travels through the walls of the descending thoracic aorta => Migrates to the esophageal wall and creates granulomas through which it lays its eggs.

79
Q

Spirocercosis - Time from infection to egg shedding

A

6 Months

80
Q

Spirocercosis - What season has the highest incidence? Why?

A

Winter months
