Scientists on the College of Texas at Austin have predicted that the US state goes to be hit laborious by a killer fungus.
It comes after loopy and invasive ants rolled into new components of Texas. They’re referred to as “loopy” due to their erratic, jarring actions, in contrast to the orderly marches of their cousin species.
Whereas they do not have the venomous chew of fireplace ants, they secrete formic acid that shields them in opposition to hearth ant venom, and incapacitates native animals.
Like hearth ants, whom they’ve displaced in components of Texas, tawny loopy ants are native to Argentina and Brazil and got here to the US through ships.
The “superbug” outbreaks have been reported in two hospitals at Dallas, the Facilities for Illness Management and Prevention reported. A handful of the sufferers had invasive fungal infections that have been impervious to all three main lessons of medicines.
“That is actually the primary time we’ve began seeing clustering of resistance” through which sufferers appeared to be getting the infections from one another, stated the CDC’s Dr. Meghan Lyman.
The fungus, Candida auris, is a dangerous type of yeast that’s thought-about harmful to hospital and nursing dwelling sufferers with critical medical issues. It’s most threatening when it enters the bloodstream, coronary heart or mind. Outbreaks in well being care amenities have been spurred when the fungus unfold by way of affected person contact or on contaminated surfaces.

Researchers consider a naturally occurring fungus-like pathogen can be utilized to reverse their rampant unfold throughout the southeastern United States, the place they’ve wrought havoc for the previous 20 years.
Ecologist and lead writer Edward LeBrun stated that the fungus had already pushed pockets of the invaders to extinction, and would quickly be examined at environmentally-sensitive websites to guard endangered species.
“It is sort of a horror present,” stated LeBrun, who described apocalyptic rivers of ants swarming timber at an infestation website he visited on the Estero Llano Grande State Park, which had misplaced native ants, bugs, scorpions, snakes, lizards and birds to the invaders.
Not solely are they destroying ecosystems, “they’re depressing to dwell with” for people, stated LeBrun. The ants search out electrical techniques to nest in, inflicting shorts in breaker containers, AC models and sewage pumps.
Pesticides are extremely poisonous and serve solely to gradual their progress, resulting in snowdrift piles of useless ants that need to be cleared, and the ants finally break by way of anyway.
Well being officers have sounded alarms for years in regards to the superbug after seeing infections through which generally used medicine had little impact. In 2019, medical doctors recognized three circumstances in New York that have been additionally proof against a category of medication, referred to as echinocandins, that have been thought-about a final line of protection.
In these circumstances, there was no proof the infections had unfold from affected person to affected person — scientists concluded the resistance to the medicine fashioned throughout therapy.
The brand new circumstances did unfold, the CDC concluded. Investigators reviewed medical data and located no proof of earlier antifungal use among the many sufferers in these clusters. Well being officers say which means they unfold from individual to individual.
Microsporidians generally hijack an insect’s fats cells, turning them into spore factories. The pathogen’s origins aren’t clear — maybe it got here from South America or maybe from one other insect.
Regardless of the case, scientists discovered it cropping up throughout Texas. They noticed 15 populations for eight years, discovering that each inhabitants harboring the pathogen declined, and 60 p.c of the populations went utterly extinct.
