- stranguria
- dysuria
- urinating in public places
Why does cystitis not occur all the time?

- usually the body can remove the bugs
- cystitis requires multiple predisposing factors- e.g immunosupression with virulence

What is acute cystitis?
catarrhal inflammation
may be haemorrhagic
some mild cases resolve others lead to chronic cystitis
What two types of chronic cystitis are there?
- Polypoid
- Follicular

related to animals with diabetes mellitus
-fermentation of sugar by glucose-fermenting bacteria
What is feline idiopathic cystitis?
Neurological changes in the spinal pain fibres as well as the bladder wall
What is a recurrent infection
A recurrent infection caused by the same bacterial organism is termed
a relapse and is essentially a treatment failure.
What typically causes a relapse?
- inappropriate antibiotic therapy
- or an unrecognised complicating factor
What is the most common bacterial cause of cystitis
E.Coli

hypertrophy, mucinous metaplasia and micro-abscesses,
