Chlamydia pneumoniae induces Alzheimer-like amyloid plaques in brains of BALB/c mice.
Amyloid deposits resembling plaques found in Alzheimer's disease (AD) brains were formed in the brains of non-transgenic BALB/c mice following intranasal infection with Chlamydia pneumoniae. The mice were infected at 3 months of age with C. pneumoniae isolated from an AD brain. Infection was confirmed by light and electron microscopy in olfactory tissues of the mice. C. pneumoniae was still evi...
متن کاملDetection of bacterial antigens and Alzheimer’s disease-like pathology in the central nervous system of BALB/c mice following intranasal infection with a laboratory isolate of Chlamydia pneumoniae
Pathology consistent with that observed in Alzheimer's disease (AD) has previously been documented following intranasal infection of normal wild-type mice with Chlamydia pneumoniae (Cpn) isolated from an AD brain (96-41). In the current study, BALB/c mice were intranasally infected with a laboratory strain of Cpn, AR-39, and brain and olfactory bulbs were obtained at 1-4 months post-infection (...
متن کاملSIMULTANEOUS DETECTION OF CHLAMYDIA PNEUlvlONIAE AND MYCOPLASMA PNEUMONIAE BY PCR
Both C. pneumoniae and M. pneumoniae are common causes of respiratory tract infection. At present, both are still diagnosed in the laboratory retrospectively by serology. This is despite many publications which indicate that PCR, which is not retrospective, is extremely good at detecting these organisms. We thought that a single PCR test which could detect both organisms simultaneously in a...

Background & Aim: Recurrent or chronic adenotonsillar infections mainly affect children. The prevalence of potential respiratory pathogens on the adenoid and tonsillar surfaces of children with moderate symptoms of recurrent tonsillopharyngitis and/or adeno tonsillar hypertrophy differs only slightly from that in children without symptoms of adenotonsillar disease. Chlamydia pneumoniae is a...
متن کاملA mouse model of Chlamydia pneumoniae strain TWAR pneumonitis.
Chlamydia pneumoniae is a common cause of acute respiratory infections in humans. We evaluated mice as experimental animals for C. pneumoniae. Intranasal inoculation of Swiss Webster mice with C. pneumoniae induced a prolonged course of lung infection, as demonstrated by reisolation of organisms from lungs (at 42 days) and persistence of lung pathology (> 60 days). The lung pathology was charac...
