M. felis

21
Q

What does Mycoplasma. felis cause in cats commonly

A

22
Q

Hemotrophic mycoplasma are attached to what in the host

A

Attached on outside of red blood cells

23
Q

M. hemofelis infects what

A

Cats

24
Q

How is M. hemofelis transmitted

A

Via fleas or maybe from mother to kittens

25
Q

What is the symptoms of M. hemofelis

A

Red cells are removed from circulation in spleen because they are abnormal which results in anemia

26
Q

What disease does M. haemofelis cause and what symptoms of the forms

A

Feline Infectious Anemia
Acute- depression, fever, weakness, anorexia, acute anemia
Chronic- anemia develops more slowly, weight loss but cat more alert

27
Q

M. haemofelis diagnosis

A

Blood smear and/or PCR, keep checking because chronic form intermittently positive

28
Q

M. haemofelis Treatment

A

Tetracycline for 3 weeks and steroids. Maybe a blood transfusion
May remain a carrier

29
Q

Chlamydiaceae unique characteristics

A

Obligate, intracellular and need the host to replicate because the lack metabolic properties for reproduction and survival independently

How are Chlamydophlia elementary bodies spread

A

Aerosol (inhalation), ingestion, or direct contact
