Outbreak of a Chlamydophila Psittaci Infection in Laboratory Rats
نویسندگان
چکیده
During a study on Trypanosoma equiperdum propagation in adult male Wistar rats, four rats died spontaneously. Two of the dead animals were subjected to post mortem examination. From different organs of the rats, chlamydiae were isolated and confirmed by PCR and DNA sequencing as Chlamydophila psittaci. The results show that infection with Chlamydophila psittaci may occur in laboratory rats. Such outbreaks may have influence on the results of experimental studies. Chlamydial infections in laboratory animals also pose risk to humans (zoonosis).

Isolation of Chlamydophila psittaci from pet birds in Iran
Avian chlamydiosis is one of the most important infectious diseases of birds. Despite the rapid growth of exotic bird populations in Iran, there is little or no information on the specific infections that these types of birds carry. In this study, conventional isolation methods were used in cell culture to study occurrence of infection in pet birds. Samples from the conjunctiva, choana, and clo...

Avian chlamydiosis is caused by Chlamydiophila psittaci with the highest infection rate in parrots (Psittacidae) and pigeons (Columbiformes). A two-year-old Congo African grey parrot was examined since the bird had shown clinical signs of anorexia, depression, diarrhea, and mild dyspnea and based on biochemical and hemathological analysis the bird was diagnosed as having anemia, leukocytosis, h...

BACKGROUND Psittacosis, an avian disease caused by Chlamydophila psittaci, can manifest as an acute, protracted, or chronic illness, but can also be asymptomatic. C. psittaci can persist in the host for months to years, often without causing obvious illness, and therefore poses a threat for zoonotic outbreak. We investigated the prevalence of C. psittaci from 156 tracheal swab samples from 34 d...
متن کاملExacerbation of Chlamydophila psittaci pathogenicity in turkeys superinfected by Escherichia coli.
Both Chlamydophila psittaci and Escherichia coli infections are highly prevalent in Belgian turkeys and therefore they both might contribute to the respiratory disease complex observed in turkeys. C. psittaci can infect turkeys within the first week of age, even in the presence of maternal antibodies. However, the first C. psittaci outbreaks occur mostly at the age of 3 to 6 weeks, the period w...
