Plain-English summary
A study found that 56 out of 676 dogs in Merida, Yucatan, Mexico, were infected with heartworms (Dirofilaria immitis), which can cause serious health issues. Female dogs were nearly three times more likely to be infected than males, and dogs aged three years or older were more susceptible compared to younger dogs. This information highlights the importance of regular heartworm testing and prevention, especially for older and female dogs. If you suspect your dog might be at risk, consult your veterinarian for testing and preventive treatments.

Abstract
The aim of the present study was to estimate the prevalence of Dirofilaria immitis infection, and to examine the relationship between host factors (gender, age and breed) and D. immitis infection in dogs. The study was designed as a cross-sectional study. A total of 676 dogs were examined for D. immitis infection. Adult worms (necropsy) and blood samples were collected from all animals for diagnosis of D. immitis. Blood samples were examined using a modified Knott's and thick drop techniques. Fifty-six of 676 dogs were diagnosed infected with D. immitis. The odds of infection were 2.85 times higher in female dogs, compared to male dogs (OR = 2.85, 95% CI = 1.5-5.5, P = 0.01). In addition, the odds of infection were 2.11 times higher in > or =3 years old dogs, compared with younger dogs (OR = 2.11, 95% CI = 1.1-4.2, P = 0.03). This information is important for a better understanding of the epidemiology of D. immitis in dogs in Yucatan, Mexico.
