Associations between clinical canine leishmaniosis and multiple vector-borne co-infections: a case-control serological study.

BMC Vet Res 2019 Sep 18;15(1):331. Epub 2019 Sep 18.

Molecular Diagnostic Unit, Diagnostic Laboratories, Bristol Veterinary School and Langford Vets, University of Bristol, Langford, UK.

Background: Dogs that have clinical leishmaniosis (ClinL), caused by the parasite Leishmania infantum, are commonly co-infected with other pathogens, especially vector-borne pathogens (VBP). A recent PCR-based study found that ClinL dogs are more likely to be additionally infected with the rickettsial bacteria Ehrlichia canis. Further information on co-infections in ClinL cases with VBP, as assessed by serology, is required. Read More

Feline asthma and heartworm disease: Clinical features, diagnostics and therapeutics.

J Feline Med Surg 2019 09;21(9):825-834

Department of Veterinary Medicine and Surgery, University of Missouri, Columbia, MO, USA.

Practical Relevance: For feline practitioners, the cat with a cough or respiratory distress and thoracic radiographs with a bronchial or bronchointerstitial pattern suggests lower airway disease. Two important differentials, allergic asthma and heartworm disease (HWD), have many overlapping clinicopathologic features, but also clear and important differences in terms of cause and disease progression, treatment and prognosis. Notably, asthma is readily treatable and HWD is preventable. Read More

Efficacy of imidacloprid 10%/moxidectin 2.5% spot on (Advocate®, Advantage Multi®) and doxycycline for the treatment of natural Dirofilaria immitis infections in dogs.

Vet Parasitol 2019 Sep 27;273:11-16. Epub 2019 Jul 27.

Department of Veterinary Science, University of Parma, Parma, Italy.

Heartworm infection (also known as dirofilariosis due to Dirofilaria immitis) in dogs causes chronic pulmonary disease that, if left untreated, can lead to right-side congestive heart failure. Currently, the only registered drug for adulticide therapy in dogs with heartworm disease (HWD) is melarsomine dihydrochloride. The recent targeting of the bacterial endosymbiont Wolbachia, through antibiotic therapy of the infected host, has offered an interesting alternative for the treatment of HWD. Read More
