Dirofilaria immitis is a filariid worm which typically lives as adult in the right ventricle of the heart and the pulmonary arteries of the dog, causing the canine heartworm disease. Therapy of canine dirofilariosis due to Dirofilaria immitis is indicated for dogs suffering from clinical signs of the disease (such as chronic cough). The present paper describes diagnostic and treatment features ...
The heart consists of cardiocytes and the interstitial extracellular matrix (ECM), which is made up mainly of collagens. The ECM has been suggested to be important in maintaining the structure and function of the heart. This investigation attempted to elucidate the changes in the ECM collagens in the hearts of canines with dirofilariasis. The ECM collagen fibrils of the heart are grouped into e...
BACKGROUND The heartworm Dirofilaria immitis is the causal agent of cardiopulmonary dirofilariosis in dogs and cats, and also infects a wide range of wild mammals as well as humans. One bottleneck for the design of fundamentally new intervention and management strategies against D. immitis may be the currently limited knowledge of fundamental molecular aspects of D. immitis. METHODOLOGY/PRINC...
BACKGROUND The heartworm disease is an infectious disease of dogs with Dirofilaria immitis combined with cardiovascular and circulatory abnormalities. The heartworm disease can become a serious health risk when associated with a severe infection. In this study, a male, 8 year-old dog that died suddenly was necropsied and all tissues were examined grossly. METHODS Major organs including heart,...
The heartworm Dirofilaria immitis is the causative agent of cardiopulmonary dirofilariosis in dogs and cats, which also infects a wide range of wild mammals and humans. The complex life cycle of D. immitis with several developmental stages in its invertebrate mosquito vectors and its vertebrate hosts indicates the importance of miRNA in growth and development, and their ability to regulate infe...
World-wide concern over emerging vector-borne diseases has increased in recent years for both animal and human health. In the United Sates, concern about vector-borne diseases in canines has focused on Lyme disease, anaplasmosis, ehrlichiosis, and heartworm which infect domestic and wild canids. Of these diseases, Lyme and anaplasmosis are also frequently diagnosed in humans. Gray wolves (Canis...
0304-4017/$ – see front matter doi:10.1016/j.vetpar.2005.07.009 Puerto Rico, U.S. Virgin Islands and Guam. Heartworm transmission has not been documented in Alaska and even with the importation of microfilaremic dogs, it is doubtful the climate this far north will permit maturation of infective larvae. Relocation of infected, microfilaremic dogs appears to be the most important factor contribut...
A survey was conducted in the eastern part of Romania to assess the prevalence and geographical distribution of Dirofilaria immitis in dogs. Plasma samples were collected from 458 stray dogs hosted in shelters in 8 counties and tested serologically for the presence of heartworm. In addition, 45 blood samples from dogs of a shelter in Galati city were examined by the modified Knott and multiplex...
In order to evaluate the prevalence of canine heartworm in the State of Rio de Janeiro, a multicenter survey was carried out in two phases. The survey involved 1376 dogs from two cities: Rio de Janeiro and Niterói, and its surroundings, including the eastern shore and mountain resorts, which were further divided into sections. In the first phase, 795 dog blood samples were examined by the modif...
DIROFILARIA IMMITIS by CHRISTOPHER CHARLES EVANS (Under the Direction of Ray M. Kaplan) ABSTRACT The canine heartworm (Dirofilaria immitis) is a widespread parasitic filarial nematode of veterinary importance. Anthelmintics of the macrocyclic lactone (ML) drug class have been widely and effectively used in chemoprophylaxis, but an increased number of lack of efficacy reports, in which dogs deve...
