(T/F) Contagious Equine Metritis causes permanent False
infertility in mares
Short-term infertility
What is the causal agent of Contagious Equine Metritis Taylorella equigenitalis
(CEM)
What are 4 clinical signs of symptomatic infection Think "Barren Mare" - no signs of systemic illness
contagious equine metritis (CEM)? 1. Mare "breaks dirty" 2-13 days after breeding
2. Variable inflammation of endrometrium, cervix, vagina
3. Think greyish white vaginal discharge
4. dried discharge in teh perineal area, inside the thighs and tail
If a mare is asymptomatic for CEM what will happen? Mares return to estrus after a shortened diestrous period
(T/F) Abortion is fairly common with mares infected False, very rare
with T. equigenitalis
(Contagious Equine Metritis)
How is contagious equine metritis typically spread? Via carrier stallions and mares, and failure to observe appropriate hygiene
when breeding naturally or collecting semen for A.I. Also "vanning-in" or
"walking-in" breeding practices
(T/F) The mode of transmission of contagious equine True
metritis is direct venereal contact but can also be via
A.I. with contaminated extended frozen semen, or
fomites/poor hygiene in breeding practices
(T/F) Trans-placental infection of contagious equine True
metritis can occur resulting in a carrier foal
Between the two types of CEM carriers, which are more Clitoral
common, clitoral or uterine?
, (T/F) Carrier mares and stallions are usually positive for False - usually negative
serum antibodies to T. equigenitalis
How is contagious equine metritis diagnosed (3)? Culture, cytological examination of endometrial smears, and also PCR
(T/F) Taylorella equigenitalis does not cause illness in True
the stallion, as it is a superficial commensal bacteria on
the external genitalia
(T/F) Treatment for CEM is typically systemic antibiotics False
then re-testing
Typically topical - clean affected areas with chlorhexidine then apply
nitrofurazone ointment. This should be repeated daily for 5 days
Equine Piroplasmosis is caused by what organism(s)? Babesia (Theileria) equi
Babesia caballi
(T/F) Equine piroplasmosis/babesiosis is endemic to the False
United States
How is Equine piroplasmosis transmitted? Via ticks
Are the there competent tick vectors in the United Yes
States for equine piroplasmosis?
What ticks transmit Babesia equi (equine Dermacentor variabilis
paraplasmosis)? Rhipicephalus (Boophilus) microplus
Babesia (equi/cabali) has both a reservoir in the tick and caballi
the horse
equi horse is the only reservoir
What cell gets infected with equine piroplasmosis? the red blood cell
What are 2 ways to prevent equine 1. don't transfer infected blood to another horse
piroplasmosis/babesiosis? 2. Use of permethrin based acaricides
(T/F) Equine piroplasmosis infection will destroy the red True
blood cells of the horse
(T/F) equine paraplasmosis/babesiosis is transmitted False - not very efficient
effectively from the mare to the foal
(T/F) Infected horses of equine True
piroplasmosis/babesiosis are a constant source of
parasite for transmission to ticks and uninfected horses
