United States: The prevailing bacteria has become a serious concern for health experts and authorities across the globe. With every passing day, health experts have been finding new bacteria with new complications for humans. Recently, experts have found one of the world’s deadliest bacteria – having lust for taste for human blood.

Following the discovery, the bacteria and the phenomenon is termed as “bacterial vampirism.” The recent study has unveiled a fresh perspectives on the mechanisms behind bloodstream infections and their potential treatment avenues.

Salmonella, Escherichia coli, and Citrobacter koseri stand as primary culprits in the mortality toll among individuals grappling with inflammatory bowel maladies, impacting multitudes globally. These pathogens possess the propensity to infiltrate the bloodstream via intestinal hemorrhage, precipitating perilous blood infections and sepsis, clinically termed bacterial blood poisoning, as reported by Newsweek.

Data from the US Centers for Disease Control and Prevention underscore the grim reality, with close to 270,000 American lives succumbing annually to septic episodes. Hence, a profound comprehension of bacterial ingress into our circulatory system emerges as imperative for public health endeavors.

A recent inquiry spearheaded by Washington State University ventures that the pathways of these blood-bound microbes are not mere coincidence; rather, they exhibit an active pursuit and nourishment from human blood.

“We gleaned that certain bacteria, commonly implicated in bloodstream infections, possess the ability to perceive a constituent within human blood and gravitate towards it,” elaborated Arden Baylink, a luminary at WSU’s College of Veterinary Medicine and the corresponding authority behind the investigation.

The findings, detailed in the esteemed journal eLife, emanate from observations employing sophisticated microscopy techniques, unraveling the behavioral nuances of various bacterial strains in response to the presence of human blood.

The reaction was swift, with each bacterial species homing in on the blood source in under a minute.

Upon meticulous scrutiny, the researchers unearthed that Salmonella bacteria harbor specialized receptors on their exterior, facilitating the detection of a distinctive chemical intrinsic to human blood serum. Analogous receptors are presumed to adorn the surfaces of other “vampiric” bacteria, such as Escherichia coli, Newsweek mentioned.

The conjecture posits that these bacteria likely subsist on the nutrients encapsulated within our blood serum, thereby conferring an evolutionary edge to this blood-seeking comportment.

“By deciphering the mechanisms enabling bacterial detection of blood sources, we lay the groundwork for prospective drug development aimed at thwarting this ability,” mentioned Glenn in a communiqué.

He further stated, “Such therapeutic interventions hold promise in ameliorating the plight of individuals grappling with inflammatory bowel ailments, predisposed to bloodstream infections.”
