عندما كنت احضر لموضوع قرات عن البكتيريا والتى تستخدم فى وقتنا الراهن فى تصنيع الاسلحة البيولوجية
ولكن ما هى هذة البكتيريا
انها بكتيريا
coxiella burneti
فاحببت ان اتكلم عنها ولو بالشئ المختصر
قبل ان اخوض فى التفاصيل
لابد من اقول لكم ما هى الصفات التى اهلتها لان تستخدم فى الاسلحة البيولوجية
اولا
شديدة الاصابة
مقاومة للحرارة
مقاومة للجفاف
وهاهى بعض المعلومات عنها

- coxiella burneti similar to Richettsiae
small gram negative
non-motile
it difficult to study because cannot be cultured on artificial media
coxiella burneti cultured in yolk sac of achich embryo
coxiella burneti charactarized by resistant to heat ,drying and disinfectant.
so this feature
permit to it to survive for long period in enviroment
survive one hour at 60 C
COXIELLA burneti CONSIDE zoonatic disease
reservior host
cows,sheep,cattel,goats
Transsmision
C.burneti transsmitted by
a- ticks
b- frome one animales to another in infected milk
DISEASE CAUSED BY COXIELLA.BURNETI
A-
Q FEVRE
known with name
RED RIVER FEVER
this disease present usually in
Zaire
B
Mine mile fever
How human infected
by the folloeing
a- bite of infected ticks
b-drinking untreated infected milk
c-inhaling infected aerosols
d- handling infected animales
symptoms of Qfever

symptoms of Qfever
- high fever
- headache
- body pain
- slight rash
- sore throat
- vomiting
- nausea
- non-productive cough
- confusion
complication of untreated QFEVER
- pneumonia(similar to virus pneumoa
- chronic infected endocarditis
liver disease
C.burneti parasitized in
a- histiocytes of the spleen
b- Kupffer cell of the liver
so due to the presence in liver and spleen the tow organe become enlarged
Incubation period
depend on the number of the organisms initially infected the patient
infection with greater number willresult in shorter incubation period
most patient become ill within 2-3 weeks after exposure
DIAGNOSIS
bu using serological test
such as
a- complement fixation
b-ELIZA
Treatment
byusing
a-
Doxycycline
b-
tetracycline
Q fever in pregnancy is difficut to treated because the Doxycycline are contrindicated in pregnacy
so use
Co-trimoxazole
