Term
|
Definition
Gram postive
subclinical to moderate mastitis
range from acute to chronic, abscess to granuloma
can cause gangrenous mastitis
mammary gland can be reservoir |
|
|
Term
|
Definition
Gram positive
causes subclinical persistent infection
decreased milk rpoduction
enters via teat canal and releases toxin to cause inflammation
can cause fibrosis and progressive loss of secretory function
mammary gland becomes reservoir |
|
|
Term
|
Definition
Gram negative
not as common
sudden onset of agalactia and toxemia
high mortality
edematous, necrotizing, fibrinous/hemorrhagic
ascending infection or hematogenous |
|
|
Term
|
Definition
summer mastitis
mixture of organisms with Strep dysgalactiae
occurs in nonlacting/dry cows
ascending infection from teat
neutrophilic response to cause suppuration
need to monitor dry cows
can lead to fibrosis and involution of quarter |
|

Definition
Arcanobacterium
Streptococcus agalactiae (acute)
Staphylococcus
Mycoplasma bovis (acute) |
|
|
Term
|
Definition
sudden onset of agalactia
spreads rapidly in herd
milk forms floccular deposit and clear supernatant on standing
swollen, firm for weeks
starts as suppurative then lymphocytic then fibrosis
hematogenous or ascending infection |

Cryptococcus |
|
|
Term

Definition
parapox virus
most common infectious teat disease
immunity is short lived so cows get infected within 6 months after recovery |

|
Term
| Visna-Maedi/Ovine Progressive Pneumonia |
|
Definition
lentivirus
causes mammary disease early on
reduce milk year, poor weaning lamb growth, progressive atrophy of both glands
lymphoplasmacytic infiltrations in connective tissue of glands |

|
|
Term
| Mastitis-Metritis-Agalactia Syndrome |
|
Definition
in swine
12-48 hours postpartum
fever, swelling, firmness of mammary gland
agalactiae
due to E.coli and others
common in intensive units |
|
|
Term
| Mammary Gland Neoplasia in Dog |
|
Definition
occurs in intact females
spaying early has good effects but spaying once the neoplasia has manifested does nothing
impossible to differentiate malignant/benign mammary tumor in dog clinically
about 30% of tumors are malignant |
|
|
Term
| Benign Mixed Mamamry Tumor |
|
Definition
most common mammary tumor in dog
multiple masses with good prognosis
firm, cystic, encapsulated nodules
often contain a mixture of tissue histologically |
|
|
Term
|
Definition
tumor type (complex, insitu, ductal)
histologic grading
presence of necrosis
infiltration/invasion of surrounding tissue
regional lymph node/lung metastasis |
|
|
Term
| Mammary Gland Neoplasia in Cat |
|
Definition
80% are malignant
more frequent than in dog
old age, large, histologic grading
necrosis, metastasis |
|
|
Term
|
Definition
occurs in pregnant or very young cats
induced by progesterone in one or all mammary glands
treat by spay, terminate pregnancy, or terminate progestin treatment |
