Mycoplasma and Chlamydophila Flashcards
Mycoplasma is unique in size and genome how
Simplest, smallest self replicating extracellular prokaryote
What doesn’t have a cell wall (type of bacteria) and affect with antibiotics
Mycoplasma so resistant to antibiotics that target cell wall
Are mycoplasmas host specific
Yes- host species specific- each species only cause disease in its particular host
How are mycoplasmas divided/ organized
Hemotrophic and non-hemotrophic types
Do mycoplasma have antigenic variation
Yes
How is non-hemotropic mycoplasma transmitted
Aerosols in droplets
Are asymptomatic carriers a problem with mycoplasma
Yes
What are symptoms of non-hemotropic mycoplasma
*associated with inflammation of mucosal and serosal surfaces of respiratory tract, joints, mammary gland, and conjunctiva
Mycoplasma gallisepticum causes what disease in what animal
Poultry, Chronic Respiratory Disease
Mycoplasma gallisepticum spread by what and what signs
Carrier animals, diseased animals have respiratory signs, arthritis, and decreased egg production, airsacculitus
Mycoplasma gallisepticum Diagnosis
Culture, PCR from tissue, ELISA on serum
Mycoplasma gallisepticum Treatment and prevention
Antibiotics in water and there is a vaccine
Non-hemotropic Mycoplasma disease cattle organism
Mycoplasma bovis and 5 other species
Mycoplasma mycoides subsp, mycoides disease is what
Contagious Bovine Pleuropneumonia (CBPP)- very contagious and severe septicemia, pneumonia, arthritis, plequritis
Contagious Bovine Pleuropneumonia Reportable?
Yes
Mycoplasmas in swine and what they cause
M. Hyopneumoniae- enzootic pneumonia M. Hyosynoviae and M. Hyoriunitis- both can cause arthritis in pigs
Mycoplasmas in goats and what they cause
M. Capricolum ssp. Capricolum cause mycoplasmosis presenting as poly arthritis, mastitis, and/or pneumonia and ssp. Capripneumoniae causes Contagious Caprine Pleuropneumonia which is fatal pleuropneumonia
Contagious Caprine Pleuropneumonia reportable?
yes
Mycoplasma in dogs and causes what
M. canis causes UTIs
Mycoplasma in cats
M. felis
What does Mycoplasma. felis cause in cats commonly
Conjunctivitis
Hemotrophic mycoplasma are attached to what in the host
Attached on outside of red blood cells
M. hemofelis infects what
Cats
How is M. hemofelis transmitted
Via fleas or maybe from mother to kittens
What is the symptoms of M. hemofelis
Red cells are removed from circulation in spleen because they are abnormal which results in anemia
What disease does M. haemofelis cause and what symptoms of the forms
Feline Infectious Anemia
Acute- depression, fever, weakness, anorexia, acute anemia
Chronic- anemia develops more slowly, weight loss but cat more alert
M. haemofelis diagnosis
Blood smear and/or PCR, keep checking because chronic form intermittently positive
M. haemofelis Treatment
Tetracycline for 3 weeks and steroids. Maybe a blood transfusion
May remain a carrier
Chlamydiaceae unique characteristics
Obligate, intracellular and need the host to replicate because the lack metabolic properties for reproduction and survival independently
Chlamydia and Chlamydophila are in genus
Chlamydophlia
Where are Chlamydiaceae Often found
Epithelial cells of conjunctiva, respiratory, GI tract, and genitourinary tract cells
Chlamydial infections resemble what
Non-hemotrophic Mycoplasma ssp. infections
What is the infectious form of Chlamydophlia
Elementary body
How are Chlamydophlia elementary bodies spread
Aerosol (inhalation), ingestion, or direct contact
Chlamydophlia psittaci causes what disease
Avian Chlamydiosis or Psittacosis or Parrot fever
Is Chlamydophlia psittaci Zoonotic?
Yes, can cause pneumonia, fever in humans
Chlamydophlia psittaci reportable?
Yes
Chlamydophlia psittaci Diagnosis
Clinical signs, gross lesions, serology to detect antibody, or PCR
**wont grow on standard culture media
Chlamydophlia psittaci Treatment
Antibiotics
Chlamydophlia abortus causes what disease in what
Enzootic abortion in sheep- late term abortion, sheep seem fine before aborting
Chlamydophlia abortus Zoonotic?
Yes and can make humans abort too
Chlamydophlia abortus Vaccine?
Yes
Chlamydophlia felis spread?
From mom to kittens usually during birth
Chlamydophlia felis Treatment
Antibiotics
Chlamydophlia felis Vaccine?
Yes but not commonly used
Chlamydophlia felis Disease
Conjunctivitis in kittens
