Prevalence of Bartonella species and 16s rRNA gene types of Bartonella henselae from domestic cats in Thailand.

Abstract

Abstract. Prevalence of Bartonella infection among 275 cats in 9 sites from 4 geographical regions (northern area: Chiang Mai; central area: Kanchanaburi, Ratchaburi, and Bangkok; northeastern area: Khon Kaen, Roi Et, Ubon Ratcharthani, and Nakhonratchasima; southern area: Songkhla) of Thailand was investigated. Overall, Bartonella species were isolated from 27.6% (76 of 275) of the cats. The isolation rate varied from 12.8% (5 of 39) in Songkhla (southern area) to 50.0% (26 of 52) in Khon Kaen (northeastern area). Bartonella henselae and B. clarridgeiae were isolated from 82.9% (63 of 76) and 11.8% (9 of 76) of the Bartonella-positive cats, respectively. Coinfection with both species was found in 5.3% (4 of 76) of the bacteremic cats. Of the 67 bacteremic cats from which B. henselae was isolated, 48 (71.6%) and 13 (19.4%) were infected with only Type I and Type II, respectively. Coinfection with both types was observed in 9.0% (6 of 67) of the B. henselae-positive cats. To our knowledge, this is the first report on the presence of Bartonella infection in domestic cats from Thailand, which constitute a large reservoir of Bartonella infection in this country.

Molecular Detection of Rickettsia felis, Bartonella henselae, and B. clarridgeiae in Fleas from Domestic Dogs and Cats in Malaysia

“…6,[23][24][25][26][27] In this study, the rate of co-infection (4.8%) of B. henselae and B. clarridgeiae in our flea samples was low when compared with high rates (approaching 90%) reported in a previous study. 6 The genogroups of B. henselae vary in human and animal samples in different geographic regions.…”

BartonellaSpp. in Pets and Effect on Human Health

“…A B . clarridgeiae prevalence of 17% to 36% among all Bartonella isolates was reported in studies conducted in France, the Netherlands, the Philippines, and Thailand ( 2 , 22 ). However, B .…”

Cat-scratch disease in veterinary-associated populations and in its cat reservoir in Taiwan

“…Both B. henselae and B. clarridgeiae have been isolated from cats in some of these countries, including Indonesia, Thailand, Philippines and Japan [8,24,26,27]. The prevalence of bacteremia ranged from 6.4% to 89% for B. henselae [8,[25][26][27] and 0.7% to 31% for B. clarridgeiae [8,26,27]. Co-infection with B. henselae and B. clarridgeiae were reported in cats from the Philippines and Japan [8,26].…”

“…In Asian countries, the results showed that seroprevalence of B. henselae among cat populations in Japan ranged from 9.1 to 15.1% [28,36], 68% in Philippines [8], 48% in Singapore [29] and 54% in Indonesia [24]. Both B. henselae and B. clarridgeiae have been isolated from cats in some of these countries, including Indonesia, Thailand, Philippines and Japan [8,24,26,27]. The prevalence of bacteremia ranged from 6.4% to 89% for B. henselae [8,[25][26][27] and 0.7% to 31% for B. clarridgeiae [8,26,27].…”

“…This is the highest prevalence (9.2%, 12/131) of coinfection with B. henselae type I and type II in cat population that has ever been reported worldwide [4,13,27]. In most Asian countries, B. henselae isolates from cats belong predominantly to type I , even if the number of cats tested is rather small [5,26,27]. Similarly, we identified a higher proportion of Bartonella-bacteremic cats with B. henselae type I infection than type II infection.…”
