| mosquito frequency and feeding habits in an enzootic canine dirofilariasis area in niterói, state of rio de janeiro, brazil. | heartworm, a chronic fatal mosquito-borne canine disease, is frequently diagnosed in dogs from the state of rio de janeiro, where its prevalence is 29.7% in the city of niterói. nevertheless it is rarely detected in cats (0.8%) from the same state. dogs are the primary source of infection to mosquitoes. because cats either do not demonstrate microfilaremia or it is too low and transient for transmission. a mosquito survey was conducted in itacoatiara, niterói, from march 1995 to february 1996, u ... | 1998 | 9698883 |
