Man infected by unknown bacteria after cat bite

A 48-year-old man in the UK was bitten by a stray cat, causing a soft tissue infection A new study shows that the bacteria is caused by a hitherto undescribed bacterium.

In a case report recently published in the journal emerging infectious diseases, It described how in 2020 the man was taken to the emergency room with swollen hands, multiple stab wounds and abrasions.

eight hours ago A feral cat had bitten him several times. Doctors cleaned and bandaged the man’s wound, gave him a tetanus shot and administered antibiotics.

However, when he returned to the hospital the next day, his left little and middle fingers were painful and swollen, and both forearms were red and swollen. The wound is cleaned again thoroughly, the damaged tissue is surgically removed, and antibiotics are given intravenously. Fortunately this time, he made a full recovery after five days of oral antibiotics.

Back at the hospital, doctors, including those at Cambridge University Hospital in England, were scrambling to figure out what had happened. When they analyzed the microbes present in his wound samples using genome sequencing and biochemical analysis, they found an unidentifiable organism that had never been seen before.

Initially, when researchers analyzed infected swabs, it resembled Streptococcus, a bacterium associated with various diseases such as pharyngitis and conjunctivitis. Genome analysis, however, revealed that the bacterium was completely new and belonged to a genus of Gram-positive bacteria known as Gram-positive bacteria. ball cat

Warning to the public about cat bites

Due to its resistance to many traditional antibiotics, Sulfobacillus It poses a challenge for its complete eradication in vivo. Fortunately, a new variant discovered in the UK that responds positively to certain antibiotics offers a glimmer of hope. However, the situation serves as an important warning to the public.

“The report highlights the role of cats as a repository of bacterial species“It has not been found to have pathogenic potential in humans,” the study authors wrote.

Cat bites can cause deep wounds, experts say And because of direct inoculation with saliva, the risk of secondary infection is higher.

“In conclusion, cat bites are a common source of zoonotic infection,” they continued. Cats have previously been linked to a variety of bacterial infections, including pneumonic plague, and also transmit other parasites, such as the brain-damaging Toxoplasma gondii.

People are advised to wash cat bites with soap or salt immediately and seek medical attention immediately.
