“…Research on chlamydiosis in turkeys started in 1948 after a number of cases of psittacosis occurred among employees of a Texas poultry processing plant following the handling of diseased turkeys (Irons et al, 1951). Since then several outbreaks have been reported in turkeys in the USA.…”

“…Since then several outbreaks have been reported in turkeys in the USA. The predominant clinical sign is severe respiratory distress (Irons et al, 1951;Meyere & Eddie, 1953;Graber & Pomeroy, 1958;Page & Bankowski, 1959;Durfee et al, 1975;Hall et al, 1975;Page et al, 1975;Anderson et al, 1978;Hedberg et al, 1989;Newman, 1989;Grimes & Wyrick, 1991). In Europe, the involvement of C. psittad in outbreaks of respiratory disease in turkeys is still controversial (Lister & Alexander, 1986;Andral et al, 1989).…”

SUMMARYFour groups of 20 specific pathogen-free turkeys kept in isolators were exposed to aerosols of one of four Chlamydia psittaci strains. These were strain 92/1293 (avian serovar D), strain 84/55 (avian serovar A), the Texas Turkey strain (avian serovar D) and strain 89/1326 (avian serovar B). A further group of four specific pathogen-free turkeys consisted of sham-infected controls. The birds were observed daily for clinical signs. At daily intervals for 10 days and then twice weekly up to 34 days post-infection, one bird in each group was killed and examined for gross and microscopic lesions. Clinical signs, macroscopic and microscopic lesions were most severe in turkeys infected with strains 92/1293 and 84/55, and there was some mortality. Signs and lesions were less severe in the group infected with the Texas Turkey strain and there was no mortality. The turkeys infected with strain 89/1326 developed only mild clinical disease and lesions. Thus, differences in pathogenicity for turkeys were shown not only between strains belonging to different serovars, but also between strains within a single serovar.

among domestic fowl have increased the incidence of psittacosis tremendously. Since Ritter first described the disease under the name of pneumotyphus, psittacosis has been reported as endemic or epidemic in many parts of the world. Any attempt to determine the true incidence of the disease is futile. It is certain that psittacosis occurs much more frequently than is generally realized. That it is overlooked because of the unawareness of the medical profession of its existence is most likely.Psittacosis is an acute infectious disease caused by a number of closely related viruses. In addition to the strains of psittacine origin, there are various other strains which naturally infect other species of birds. These latter infections are referred to as ornithosis. The disease is transmitted to man primarily from infected birds. The illness is characterized by a febrile course with pneumonic changes of a diffuse interstitial nature. Since the advent of antibiotic therapy the case fatality rate of the disease has decreased from 50% to approximately 2%.The following seven cases * encountered in the past three years form the basis for this report and for a discussion of the psittacosis problem. REPORT OF CASESCase 1.-M. T., a 54-year-old woman, was hospitalized on Oct. 23 because of a febrile illness with cough and generalized aching of two days' duration. Examination of the chest revealed scattered moist rales with harsh breath sounds in the right pulmonary base and the left midlung field. The temperature was 102 F.; the pulse rate was 116 per minute, and the respiratory rate was 26 per minute. The blood pressure was 164/102. Fever (temperature to 102 F.) was present for one week, despite the daily administration of 300,000 units of penicillin procaine intra¬ muscularly. There was gradual clearing of the rales in both lung fields, and the cough and arthralgia disappeared. The patient was discharged from the hospital on Nov. 2. Cleo Roberts, B.S., gave technical assistance.
