Abstract:

Chlamydia psittaci is an obligate intracellular bacterium which causes psittacosis in psittacine birds and can be transmitted to humans by inhalation or direct contact. Birds are the primary reservoir, but transmission from other animals has also been reported. Virtually all pet birds can carry C. psittaci, but psittacine birds are the most likely to be infected. There are 10 known genotypes based on sequencing of the major outer protein gene and each genotype has host preferences and virulence characteristics. Psittacosis which was estimated to cause approximately 1 percent of cases of community-acquired pneumonia has been recognized throughout the world. The precise incidence and prevalence of psittacosis is difficult to establish, likely due to lack of reachable sensitive and specific diagnostic tests. Psittacosis has been described in all age groups but most commonly seen in young and middle-aged adults. A marked predilection for males is noted, presumably related to increased potential for exposure. Local outbreaks which related to pet shops, aviaries and veterinary facilities have been described. Patients usually present with respiratory symptoms likely dry cough due to pulmonary infection with varying severity. The most frequently reported clinical symptoms are high fever, chills, malaise, headache, myalgia, non-productive cough and respiratory distress. Infection can also be asymptomatic and other less common but important symptoms include pharyngitis, diarrhea, and altered mental status can be seen. Patients usually have a history of bird exposure. The incubation period is usually between 5 and 14 days but can be as long as 39 days. Unusual presentations which complicate making the precise diagnosis may rarely be seen. Variable clinical symptoms may arise with involvement in a number of different organs. Cold agglutinins, hemolytic anemia, acute thrombocytopenic purpura, severe pancytopenia secondary to hemophagocytic syndrome and thrombotic thrombocytopenic purpura have been described as hematologic complications. But these are uncommon manifestations.
