OBJECTIVE: This study was aimed at investigating the frequency of infection by Cp. psittaci and determining its genotype in individuals at potential risk of exposure to the bacteria.
METHODOLOGY: The study involved 170 individuals: a risk group (n= 96) and a low-risk control group (n=74). Cp. psittaci was detected and genotyped by single-tube nested PCR and ompA gene sequencing.
RESULTS: Eight (8.3 %) positive cases were detected in the risk group and 1 (1.4 %) in the control group (p<0.04). Cp. psittaci was found in 16.7 % of pigeons' fecal samples. Cp. psittaci infection with was more frequent in symptomatic (17.7 %) than asymptomatic (6.3 %) individuals in the risk group. Analysing the genomes isolated from human and bird specimens revealed the presence of genotype B.
CONCLUSION: The presence of Cp. psittaci genotype B in the population being evaluated could have been attributed to zoonotic transmission from pigeons to humans, an underestimated potential public health problem in Venezuela requiring the health authorities' involvement.
