Abstract

Urine samples of human's mid-stream urinary tract were collected
from patients (males and females)who suffered from signs of urinary tract
problems . These specified bacteria were isolated and classified according to
species .Bacteriological results indicated the existence of P.mirabilis, which was
the most familiar kind to cause these infections compared to other bacteria .
A dose of 9.0 × 109 alive P.mirabilis bacterial cells was injected after
being killed on bases of a limited period of time intraperitonially in each
laboratory rat ,signs of infections were noticed and later extra
histoimmunopathological changes were studied in accordance with their sickness
stages.
Results Showed the followings:
Bacterial infections were persistent and their severity was varied between
acute and chronic infections for all the period of the experiment .These
conditions were positive for all the urinary tract components, urethras ,urinary
bladder and urethra.
The strength of histoimmunopathological changes was varied among rats
of the same group for all the period of the experiment ,but in general these
changes varied from simple to moderate specially in the first week of inoculation
.However ,animals did have symptoms such as hyperemia and edema while
others suffered from necrosis , staffing of medulla , hyaline casts and
inflammatory edema .
Inflammation severity was increased after the first week and animals
suffered from a wide destruction in their kidney tissue because of inflammable
edema which experienced neutrophils penetration in the kidney tissues and the
collective tubules ; as a result, R.B.C `s were presented in their urine . Moreover,
in the second week their inflammatory conditions were variably extended to
chronic inflammation in the bladder through the urethras and then to urethra .
Also, swelling of the mucous membrane of the bladder and urethra. Rats may
have inflammable edema and chancre with severe edema in the inflamed cells
