Normally , dogs recover from respiratory illnesses evenhandedly easily , either on their own or with the helper of antibiotic drug in the case of bacterial infection , Dr. Kurt Williams , music director of the Oregon Veterinary Diagnostic Laboratory at Oregon State University , toldThe New York Times . Usually dogs retrieve from kennel cough , for example , within seven to 10 days . However , this outbreak is different .

" In these dogs , either it linger for longer or it consume a downward spiral and led to very serious outcomes , including last , " Williams said . It seems that serious resultant are more likely to happen in honest-to-god dogs or those with existing health issues , The New York Times reported .

" Long story short , it ’s a unearthly bacterium that can be problematic to regain and sequence , " he tell . ( Sequence refers to analyze an being ’s DNA code . )

Needle and his team have been tracking the eruption since last year . So far , they have genetically sequence 30 clinical samples from dogs that fall ill in New Hampshire last yr , as well as 40 dogs from Rhode Island and Massachusetts that mother sick this twelvemonth . Twenty - one of the 30 New Hampshire samples were identify as the same unusual bacterial species , NBC reported .

Needle ’s squad has n’t been capable to grow the bacteria in research lab dish yet , so they have n’t had the opportunity to directly examine how antibiotic drug affect it , Needle toldNBC word . However , they can take out some cue from its structure and genetic code .

The specific pathogen behind the ongoing irruption has n’t been identified , Needle stressed , and it ’s still ill-defined whether the one they ’ve found is the same one infect dogs across the land . Needle thinks the newfound bacteria may have germinate from a microbe commonly find in the dog microbiome — the collection of microbes and virus that live inside and on the airfoil of their soundbox .

Since former October , she ’s treated about 35 dogs with the disease and all of them had lately spent time in boarding facility , doggy mean solar day care or dog parks . Four dog died or had to be euthanized . " The veterinary biotic community as a whole is kind of scared , " she say .

However , other vets reckon that dog owner should be cautious but not apprehensive about the contagion . In Oregon , for object lesson , the phone number of wienerwurst with the mysterious infection represents only a pocket-sized fraction of the entire number of cad in the state , Dr. Stephen Kochis , chief medical officeholder for the Oregon Humane Society , separate The New York Times .
