The CDC has provided the following information regarding the outbreak. Since the last update on July 21, 2020, an additional 87 ill people have been reported in this outbreak, including 38 from 8 new states: Arizona, Florida, Idaho, Maine, North Dakota, Nebraska, South Dakota, and Virginia. The outbreak has infected a total of 212 people infected with the outbreak strain of Salmonella Newport have been reported from 23 states. There have been 31 hospitalizations have been reported.
The latest data from a national surveillance system that monitors foodborne bacteria for antibiotic resistance shows rising resistance to commonly used drugs to treat Salmonella infections.
The One Health Zoonotic Disease Prioritization workshop produced a list of eight endemic and emerging diseases ranked according to epidemic and pandemic potential, risk for introduction, or increase in transmission within the US.
The Centers for Disease Control and Prevention (CDC) released a report on an unusual 255-case outbreak of Salmonella Newport infections in 32 states tied to both beef and soft cheese and showing resistance to multiple antibiotics.
The Statens Serum Institut (SSI) of Denmark is currently investigating an outbreak caused by a rare strain of Salmonella that was reported from May 31 to June 25, 2019. While SSI conducts interviews of patients and waits for the whole genome sequencing result, the agency cannot confirm that the outbreak is no longer ongoing.
Researchers found a gene that gives Salmonella resistance to antibiotics of last resort in a sample taken from a patient in the United States. This is the first evidence that the mcr-3.1 gene has made it into the US.
Using 2008-2016 strain data, researchers demonstrated that genetic networks of salmonella pathogens are linked through just a few degrees of separation, indicating an increasing severity of future epidemics.
Unlike other disease-causing bacteria that enter the root, fruit or leaf by producing enzymes to break down the plant's cell wall, salmonella sneaks in through a tiny gap created when a lateral root branches out from the plant's primary root.
Extended-spectrum β-lactamases (ESBLs) confer resistance to clinically important third-generation cephalosporins, which are often used to treat invasive salmonellosis. In the United States, ESBLs are rarely found in Salmonella. However, in 2014, the US Food and Drug Administration found blaCTX-M-65 ESBL-producing Salmonella enterica serotype Infantis in retail chicken meat.
Researchers had a recent breakthrough toward creating a better Salmonella vaccine, by understanding how memory T cells could provide better protection against Salmonella infection.
