Plain-English summary
Chlamydiosis, also known as psittacosis, is an infection caused by a specific bacterium that can affect both birds and humans. In this case, a dead cockatiel and two budgerigars were tested, along with a child who lived with them. The tests showed that the birds were infected, but the child did not have the infection in their blood. This situation highlights the importance of getting birds from reliable sources, watching for signs of illness in both birds and people, and following strict hygiene practices to prevent the spread of this disease. The findings suggest that the birds were carrying a particularly harmful strain of the bacteria.
Abstract
The causative agent of chlamydiosis/psittacosis, the obligatory intracellular bacterium, infects various species of birds and humans. Infected birds occasionally excrete the pathogen through the respiratory and digestive systems, with nasal/ocular discharge and feces being the main sources of infection for other birds or humans. Humans are most often infected through close contact with positive parrots. In this case report of avian chlamydiosis/psittacosis, samples were taken from a dead cockatiel and two budgerigars, and from a child living in the same household as the birds. In all the samples examined, except the child's serum,was detected by real-time PCR. The phylogenetic analysis of thegene from parrot isolates identified genotype A, confirming that parrots harbored the most virulent genotype of. To prevent the spread of avian chlamydiosis/psittacosis, it is necessary to procure birds from verified sources, monitor the signs of disease in parrots and humans, and strictly adhere to biosecurity measures to prevent further spread of the disease.
