The curious Galactic features near G357.2$-$0.2 were observed with the MeerKAT radio interferometer array in 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"), series of previously known but now much better imaged narrow, curved "Worm") interior to heart. Polarized emission suggests that is nonthermal emb...

This study was conducted to evaluate protective efficiency of three different protocols for vaccination in canine heartworm infection. To evaluate the three protocols of immunization, dogs were separately immunized with living larvae; 1) immunization with gamma-attenuated infective larvae, 2) with 50 micrograms/kg ivermectin-abbreviation, and 3) with chemical abbreviation plus Freund's complete...

We determined the prevalence of Dirofilaria immitis (Nematoda, Filariidae) among 433 red foxes (Vulpes vulpes) in northeastern Spain, between 1990 and 1992. Forty-six (11%) of 433 foxes were infected; the intensity ranged from 1 to 36 (mean +/- SE; 4.39 +/- 0.92) nematodes per host. The prevalence of D. immitis was higher in foxes inhabiting riparian zones of the study area. This population has...

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,...
