Abstract:
This study was aimed at investigating the distribution of Bartonella in rodents,and analyzing the prevalence of the virus in Inner Mongolia.Rodent liver,spleen,and kidney tissue samples were collected from Hohhot,Baotou,Chifeng,Tongliao,Ordos,Bayannur,Ulanqab,Xingan League,Xilin Gol League,and Hulun Buir in the Inner Mongolia Autonomous Region from 2022 to 2023.Bartonella pathogens were detected with TaqMan probe fluorescence quantitative PCR(qPCR).The samples that tested positive by qPCR were amplified by PCR;those with positive results were sequenced,and genetic evo-lution analysis was performed.A total of 799 rodents were captured,including 271 mice(33.92%,271/799),188 Rattus nor-vegicus(23.53%,188/799),and 188 long-claw gerbils(23.53%,188/799).Tissue test results indicated 49 qPCR positive samples,with a positivity rate of 6.13%(49/799),29 of which subsequently had positive PCR findings.Sequence analysis and genetic evolution analysis indicated detection of four Bartonella species,B.Krasnovii(55.17%,16/29),unnamed Bartonella(34.48%,10/29),B.ribocorum(6.90%,2/29),and B.rochalimae(3.45%,1/29),in rodents from Inner Mongolia.Bar-tonella infection in rodents was widespread in many cities of Inner Mongolia,and showed genotype and host diversity.The surveil-lance of pathogens carried by rodents should be strengthened,and the prevention and control of rodent borne diseases should be opti-mized to decrease the risk of human infection.
