A 48-year-old man in the UK was bitten by a stray cat, which led to a severe infection caused by a newly discovered bacterium. This case highlights the potential risks of cat bites, especially from stray or feral cats, and the role cats may play in spreading unknown bacteria that could be harmful to humans.
The Incident
In 2020, the man was admitted to the emergency department after being bitten by a stray cat. He developed painful swelling in his hand along with multiple puncture wounds and abrasions. The man, who was obese, was treated with antibiotics, a tetanus booster, and sent home. However, about 24 hours later, he returned with worsening symptoms, including infection in his fingers.
Doctors had to surgically remove the damaged tissue and administer stronger antibiotics intravenously. Fortunately, this treatment worked, and he eventually recovered.
The Bacteria Behind the Infection
When doctors analyzed a sample from the man’s infected finger, they discovered a new type of bacterium. It appeared similar to Streptococcus, a bacteria linked to conditions like strep throat and meningitis, but the genome didn’t match any known strains. This suggested that the bacteria was a new species, never seen before.
The bacteria was identified as belonging to a genus called Globicatella, a type of gram-positive bacteria. This finding is significant because it shows that cats may be hosts for previously unknown bacteria that can be harmful to humans.
Cats and the Risk of Infection
This case sheds light on the hidden risks of cat bites, especially from stray cats. Cats have sharp teeth, and their bites can cause deep wounds. When a cat bites, its saliva can introduce harmful bacteria directly into the wound, leading to severe infections if not treated promptly.
Experts recommend that anyone bitten by a cat should immediately wash the wound with soap or salt water and see a doctor right away. Timely medical attention can help prevent infections from spreading.
Why This Matters
This new research is a reminder of how animals, including cats, can act as carriers for bacteria that may not yet be discovered. While most cat bites are not serious, it’s important to understand that there is always a risk of infection, especially with stray or feral cats.
The findings also highlight the need for more research into how cats and other animals can carry and spread new bacteria that could potentially harm humans. With more studies, we can better understand the dangers of animal bites and how to protect ourselves from infections.
In conclusion, while cats are often loving pets, their bites should not be taken lightly. Always take immediate action if bitten, and be aware that new bacteria could be lurking, ready to cause trouble.
