| Abstract |
This study surveyed the prevalence of chlamydial infection among farms in the mid-northeastern provincial cluster of
Thailand by PCR and phylogenetic analyses of the sequences. Samples from 94 crocodiles were collected from 17 farms in
five provinces together with farm management data. Chlamydiaceae was found in 48.94% of the samples (46/94). Of the 17
pooled samples analyzed using 16S rRNA sequencing, four samples exhibited 99.3 to 99.5% nucleotide identity with
Chlamydia psittaci, three samples exhibited 99.1 to 99.3% nucleotide identity with C. crocodili, and one sample exhibited
similarity to both species. The risk factors related to chlamydial infection included the source of young crocodiles and the
frequency of water changes. Chlamydial infection was higher in nonclinical crocodiles than in clinical or dead crocodiles
(P=0.003). Pharyngitis, fibrinous pharyngitis, hepatitis, pneumonia, and hydropericardium were commonly found in
chlamydial-positive cases of ill or dead crocodiles. C. psittaci and C. crocodili were found in both clinical and nonclinical
crocodiles. C. psittaci is a well-known zoonotic pathogen. C. crocodili is a new species found in Siamese crocodiles in
Thailand. In conclusion, the source of young crocodiles and frequency of water changes were identified as risk factors for
chlamydial infection in crocodile farms. C. crocodili should be further investigated to better understand its implications for
crocodile health. |
