Pictures of streptococcus. A man in Michigan will ask to have some of his hands and feet amputated after suffering from severe strep throat. However, how can the bacteria that cause streptococcal infection cause such serious complications? According to CNN, Kevin Brin, a 44-year-old man, first entered the emergency room with flu-like symptoms and stomachache in late February last year. Then his stomach began to swell and he was taken to the operating room. Doctors found a lot of pus around his organs, but they didn't know his cause.

A big clue is that when Brin has a rash on his chest after surgery, it may be a symptom of streptococcus infection. In fact, CNN said that the test result was positive for streptococcus, a bacterium that causes pharyngitis. [27 devastating infectious diseases]

Unfortunately, according to Brin's GoFundMe page, his infection caused him septic shock. According to the National Institutes of Health,

Septic shock is a life-threatening complication. Infection can lead to dangerous hypotension. NIH said that this happens when toxins released by bacteria and the body's own inflammatory response to inflammation damage body tissues and cause blood pressure to drop. "KDSP" and "KDSP", when people experience a sharp drop in blood pressure, their bodies begin to shunt blood to important organs. Dr. Amesh Adalja, an infectious disease expert at the University of Pittsburgh Medical Center, told Battlefield Science in an interview on 20 15:

In Brin's case, his hands and feet began to turn black due to the death of tissue. Brin will undergo an operation to remove the fingers and feet of his left and right hands. According to his GoFundMe page,

Brin's complications are extremely rare-according to the Centers for Disease Control and Prevention, in most cases of strep throat, bacteria can infect the throat and tonsils, and cause symptoms such as sore throat, fever and erythema on the roof, especially in the oral cavity. But bacteria can spread to other parts of the body, including sinuses, skin and ears.

On Brin, the bacteria spread to his stomach. According to new york Daily News, there were only 32 cases of stomach infection with streptococcus, among which only two men participated.

Before Brin got sick, his son was infected with Streptococcus laryngis. Brin went to see a doctor to see if he was infected with Streptococcus laryngis. However, according to the National Broadcasting Corporation (NBC), the first bacterial test was negative. According to the data of HealthPartners, a non-profit medical institution, about 10% to 20% of the test results of strep throat are "false negative", which means that when a person is really sick, the results are negative.
