Falcons from the United Arab Emirates infected with Chlamydia psittaci/C abortus intermediates specified as Chlamydia buteonis by Polymerase Chain Reaction
Chlamydiaceae are obligate intracellular bacteria with a broad host range. Several studies have found chlamydial species that are genetically intermediate between Chlamydia psittaci and Chlamydia abortus in various avian species. One of these intermediate Chlamydia species, found in a red-shouldered...

Chlamydiaceae are obligate intracellular bacteria with a broad host range.
