The Curious Case of the “Heartworm” Nebula

The Astrophysical Journal, 2022
Abstract The curious Galactic features near G357.2−0.2 were observed with the MeerKAT radio interferometer array in the UHF and L bands (0.56–1.68 GHz). There are two possibly related features: a newly identified faint heart-shaped partial shell (the “heart”), and a series of previously known but now much better imaged narrow, curved ...

Diagnostic Investigation of Two Cases of Oslerus osleri Infection in Dogs: Microscopic Challenges and Molecular Characterisation. [PDF]

Vet Med Sci
Two cases of young dogs with chronic cough were investigated, one with bronchoalveolar lavage for cytology, the other with endoscopic biopsy for histopathology. DNA was extracted from stained smears and from formalin paraffin‐embedded blocs, six primer pairs spanning the ribosomal RNA gene of O.

Detection of heartworm antigen without cross-reactivity to helminths and protozoa following heat treatment of canine serum

Parasites & Vectors, 2021
Background Detection of Dirofilaria immitis, or heartworm, through antigen in sera is the primary means of diagnosing infections in dogs. In recent years, the practice of heat-treating serum prior to antigen testing has demonstrated improved detection of

Increasing incidence of Dirofilaria immitis in dogs in USA with focus on the southeast region 2013–2016

Parasites & Vectors, 2018
Background A recent American Heartworm Society (AHS) survey on the incidence of adult heartworm infections in dogs in the United States of America showed a 21.7% increase in the average cases per veterinary clinic from 2013 to 2016. The analysis reported

Validation of immune complex dissociation methods for use with heartworm antigen tests

Parasites & Vectors, 2017
Background Antigen testing is routinely used to diagnose canine Dirofilaria immitis infections. Immune complex dissociation (ICD) methods, which were employed in the original heartworm antigen tests to release antigen that was bound by endogenous canine ...

Updated canine infection rates for Dirofilaria immitis in areas of Brazil previously identified as having a high incidence of heartworm-infected dogs

Parasites & Vectors, 2014
Background Canine heartworm infections were frequently diagnosed in Brazil before the new millennium. After the year 2000, the frequency of diagnosis showed a sharp decline; however, a few years later, new evidence indicated that the parasite was still ...

Investigating management choices for canine heartworm disease in northern Mississippi

Parasites & Vectors, 2017
Background There are concerns that the chronic use of macrocyclic lactone preventives to kill adult heartworms (“soft-” or “slow-kill”) may have contributed to the development of macrocyclic lactone resistance.

Mosquito diversity and dog heartworm prevalence in suburban areas

Parasites & Vectors, 2020
Background Urbanization is occurring rapidly on a global scale and is altering mosquito communities, creating assemblages that are characteristically less diverse. Despite high rates of urbanization and ample examples of vector-borne diseases transmitted

Factors influencing U.S. canine heartworm (Dirofilaria immitis) prevalence

Parasites & Vectors, 2014
Background This paper examines the individual factors that influence prevalence rates of canine heartworm in the contiguous United States. A data set provided by the Companion Animal Parasite Council, which contains county-by-county results of over nine ...

Management and outcome of intracardiac heartworms in dogs

Parasites & Vectors, 2023
Background Intracardiac heartworm (IH) disease is a serious condition that can become life threatening if the patient develops caval syndrome. We aim to describe the management and outcome of IH in dogs evaluated by Medvet’s New Orleans cardiology ...
