How is the conjunctivitis and pneumonia form of chlamydiae transmitted
Contact with infectious exudates- fecal oral, aerosol
What is the pathogens is of chlamydiae causing conjunctivitis and pneumonia
Replication in mucous membranes and respiratory epithelium
How is the abortion form of chlamydiae transmitted
Contacts with aborted fetal/placental tissues, fecal-oral, aerosol
What is the pathogens is of the abortion form of chlamydiae
Target the trophoblast layer of placenta
What samples do you want to collect for suspected chlamydiae infection
Fetal, placental tissues, conjunctival swabs
What tests do you want to run for chlamydiae
PCR
What is tx for chlamydiae

Pajaroellobacter abortbovis
How is Pajaraoellobacter abortibovis transmitted
Ornithodoros caricaceus ticks
Who is affected by pajaroellobacter abortibovis
First calf heifers
How is P. Abortibovis dx
PCR or IHC of aborted fetal tissues
How do you prevent P. Abortibovis
- Live vaccine- vaccinate 60 days prior to breeding
- Avoid ticks
What does Moraxella Bovis cause in cattle
Bovine conjunctivitis
How do you interpret these conjunctival swab findings for suspected Moraxella Boris
breeding bull is carrier, numbers are decreasing over time
Heifers are infected, numbers increasing with time
How is Moraxella bovis causing bovine conjunctivitis transmitted
Direct contact with infected/asymptomatic individuals, stressful events lead to re-emergence
What is tx for bovine conjunctivitis caused by M. Bovis
Tetracyclines, anti-inflammatories
