1
Q
T. equigenitalis general characteristics
A
- non motile
- facultative anaerobe
- oxidase and catalase positive
- nonfermentative
- microaerophilic
- fastidious
2
Q
Contagious equine metritis
A
Acute, highly contagious venereal disease of female equids
- copious purulent vaginitis, metritis, cervicitis
- temporary sterility
- abortions within first 60 days of gestation
- stallions are asymptomatic carriers
3
Q
Disease
A
- lesions confined to mucus membranes of the vagina, cervix, uterus
- no fever, not systemic
- purulent endometritis, damaged uterine epithelium covered by neutrophilic exudate
- mononuclear infiltrate of endothelial stroma
- mucoid to mucopurulent vulvar discharge or failure of conception are the main clinical signs
4
Q
Infection in females usually ________
A
Spontaneously subsides in a few weeks
- endometrial repair with no lasting impairment of breeding performance
- external signs disappear within 2 weeks, uterine infection may persist
5
Q
Infection is detected in ______
A
Placenta and newborn foals
- abortions are rare
- no lesions in stallion
6
Q
Diagnosis
A
Based on clinical signs
- definitive diagnosis requires isolation from genital tract –> selective media, amines transport with charcoal, oxidase/catalase/alkaline phosphatase positive
- serology is useful for detection of acutely infected mares –> carrier mares and stallions are negative
7
Q
Carriers
A
- recovered mares: clitoral fossa and sinuses
- stallions: prepuce, urethra, urethral fossa
8
Q
Treatment
A
- mares: cleansing of clitoral fossa with chlorahexidine and nitrofurazone ointment for 5 days
- uterine irrigation and systemic antibiotics
- stallions: cleansing of urethral fossa and sinus, prepuce, and penis with chlorhexidine and nitrofurazone ointement for 5 days
9
Q
Control
A
- mares: should culture negative after 1 week of treatment, should be negative on 3 successive cultures
- stallions: culturing and test breeding
- reportable disease, state, and federal!!!
- strict quarantine on imported horses >2 yrs old
