Seroepidemiology of Feline Chlamydiosis by Microimmunofluorescence Assay with Multiple Strains as Antigens

Recent Epidemiological Status of Feline Upper Respiratory Infections in Japan.

“…They all typically suffered from conjunctivitis, and the second most frequent clinical sign was rhinitis found in 6 cats. The present prevalence rate (26.9%) was as high as those reported in Australia [28], Britain [16,29], Canada [14], Japan [6,21], New Zealand [7], and the U.S. [19] where cats with the URI or ocular disease were subjects of investigation. In contrast, the prevalence in healthy cat population was relatively low [8].…”

Isolation of Chlamydia psittaci from Domestic Cats with Oculonasal Discharge in Japan.

“…In Japan, positive antibody to chlamydia has been detected in as many as 20% of healthy and diseased cats [7]. Despite this high prevalence of seropositivity, the isolation of C. psittaci from domestic cats in Japan has not been reported yet.…”

“…The seroepidemiological surveillance of C. psittaci in cats was performed from 1980 to 1999 in Japan [3,7,13]. These reports showed the chlamydial infection in cats spread gradually and widely in Japan.…”

“…Pudjiatmoko et al . [7] described that 10 out of 11 prefectures in Japan had C. psittaci antibody positive samples with prevalence rates of 5-50%. Recently, Mochizuki et al [6] reported the prevalence rate of C. psittaci in Japan was found to be 26.9% in cats with signs of conjunctivitis and rhinitis by PCR assay amplifying the ompA gene.…”

An Etiological Investigation of Domestic Cats with Conjunctivitis and Upper Respiratory Tract Disease in Japan.

“…felis and both FHV-1/FCV in cats [8,18]. Our previous seroepidemiological studies indicated that feline chlamydial infection is widely spread in cats in Japan [5,15,20]. Mochizuki et al [14] reported the epidemiological status of feline URTD and Iwamoto et al [10] reported the isolation of C. felis in Japan.…”
