Plain-English summary
A group of dogs in Hamadan, Iran, were tested for infections caused by Bartonella, a type of bacteria spread by fleas and ticks. Out of 66 dogs, 74.2% showed signs of infection, with stray dogs being particularly affected. Many of these stray dogs were also infested with fleas, which increased their risk of infection significantly. The study found that rescued stray dogs were much more likely to be infected compared to those from a breeding colony. This highlights the importance of controlling flea and tick infestations to help protect dogs from these infections.

Abstract
Bartonellae are emerging vector-borne pathogens infecting various domestic and wild mammals. Blood samples were collected from 66 dogs at two locations near Hamedan, Iran. Twenty dogs were rescued stray dogs and 46 dogs were from a breeding colony, with many of them infested with fleas, ticks, or lice. Serology was performed using an indirect immunofluorescent antibody test for,, andsubsp.. Seroprevalence was 74.2% (range: 65.2-95%).DNA amplification and sequencing identifiedsubsp.type III in seven dogs, including five rescued dogs. Two dogs were infected withand three dogs with, including two of the stray dogs coinfected withsubsp.. Rescued stray dogs were 10 times (odds ratio (OR) = 10.13, 95% CI: 1.24-82.7;= 0.03) more likely to be seropositive and eight times (OR = 8.82, 95% CI: 2.68-29.11;= 0.0004) more likely to be flea-infested than breeding dogs, confirming that arthropod infestation is a major risk factor for these infections.
