<unk>  may bear resemblance to other bodily infections such as the flu; a culture would be required to determine whether a particular patient has been infected by the specific bacteria (Pantoea agglomerans) that causes true<unk> . Confusion continues to exist as outdated or inaccurate definitions of the condition, including its causes, remain widespread, especially among intravenous drug users, who are likely to self-diagnose based on local common knowledge. Although it cannot be ruled out,<unk>  could possibly result from direct introduction of a small<unk>  fiber or other particulate matter into the bloodstream which may have attached itself to the tip of a used or blunted hypodermic needle. Another possibility is seen by the increased infection rate due to<unk>  particles introducing bacteria directly into the bloodstream.<unk> , or more specifically its symptoms, can also occur from injecting old blood back into the bloodstream. Though doing so doesn’t result in true<unk>  caused by enterobacter agglomerans, it results in presentation of<unk> ’s symptoms; fever, severe chills, myalgia, spasmodic muscles especially those of the neck and back, tachycardia, profuse hidrosis, shortness of breath, lethargy, and fatigue. I/V injection of old blood cells can introduce myriad bacterium and/or microbes into one’s bloodstream as old blood, i.e blood left behind in a previously used syringe, acts as a Petri dish for culturing such micro-organisms. A blood smear and/or culture must be performed, however, to determine the specific pathogenic organism.<unk>  has specific symptoms that differentiate it from other ailments: fever, chills, and shortness of breath. In Europe,<unk>  is commonly called "the shakes"—a reference to another common symptom of<unk> . Those with this ailment often experience violent shaking or shivering. These symptoms normally occur immediately following an injection, but there are reports of lags up to an hour in length. Under most circumstances,<unk>  is quite benign, but it is possible for it to turn into something much more serious like pneumonia. Normally, however, the symptoms of<unk>  disappear within a few hours, e.g. symptoms usually occur immediately following an injection, but there are reports of lags up to an hour in length.
