Salmonella typhimurium is one of the main pathogens causing acute gastroenteritis. It is also very important bacteria in the development of microbial genetics.
It is a group of non-adaptive or pantropic Salmonella, with a wide range of hosts, and one of the bacterial types with the highest isolation rate in the world. The bacteria can cause various infectious diseases in poultry and mammals, and can also cause human infections, which has important public health significance.
Distribution and transmission of Salmonella typhimurium
This bacteria is widely distributed in nature and exists in the intestines of poultry, livestock, rodents and other animals. The bacteria has strong resistance in the external environment.
It can multiply rapidly at room temperature, is resistant to low temperature, dry, and is not heat resistant. It can be inactivated at 55℃, 1 hour, 60℃, 25 minutes; sensitive to acid, in acidic environment with pH<2, 99% will be killed, and UV And all kinds of chemical disinfectants are sensitive.
What is Salmonella Typhimurium enteritis?
Salmonella typhimurium enteritis is an acute infectious disease caused by Salmonella typhimurium
Sources of Salmonella Typhimurium enteritis
Over the years, the number of cases has increased. Salmonella typhimurium has strong resistance to the external environment and is widely distributed in nature. Much poultry (chickens, ducks, pigeons, etc.), livestock (pigs, cattle, sheep, horses, dogs, cats, etc.), rodents and birds. These bacteria are stored in the tract, so poultry, livestock, rodents, patients and carriers are the main sources of infection.
Flies and fleas are transmission media. The infection is spread mainly through contaminated food. Salmonella typhimurium is an aggressive bacterium, which mainly invades the ileum and colon, and can also invade the entire gastrointestinal tract.
Salmonella typhimurium enteritis seasonal
Typhimurium can occur throughout the year, with a high incidence in summer and autumn (June to September), which can be sporadic or outbreak. More than half of patients are under 2 years old, and the number of illnesses is more within 6 months. In critical condition. Due to contact transmission, epidemics can occur in the infant rooms of maternity hospitals and pediatric neonatal wards.
What are the Salmonella Typhimurium harm?
Harm of Salmonella Typhimurium
Salmonella typhimurium mainly causes enterocolitis, and is the most common Salmonella infection in children. It occurs throughout the year, with the highest incidence in June to September. The vast majority of children are infants under two years old, and those younger than one year old account for 1/3 to 1/2, and they are easily popular in the neonatal room.
There are a wide range of natural foci. Much poultry, livestock, rats, birds and cold-blooded animals are natural hosts. Flies and fleas can carry the bacteria and are often infected by the mouth from contaminated water, milk and food. The incubation period is generally 8 to 48 hours.
The onset is rapid. The initial symptoms are diarrhea and fever, but some first manifestations are cough, listlessness, wet lungs, bloating or malnutrition accompanied by dehydration, and then there are obvious symptoms of diarrhea.
Detection of Salmonella Typhimurium
Salmonella is widely distributed in the natural environment. It is a harmful pathogen of zoonotic diseases. It can infect humans through food and cause typhoid fever, paratyphoid fever, sepsis and gastroenteritis.
Food poisoning cases caused by salmonella occupies the second place in the total food poisoning cases.
Therefore, the rapid and specific detection of Salmonella contamination in food is of great significance in food hygiene. In addition to traditional isolation and identification methods, there are immunological detection methods for the detection of Salmonella in food.
Although the immunological method itself is relatively fast, due to the relatively low amount of contamination of Salmonella in food, it takes a long time for enrichment culture to be detected.

What specimen can be detected by BALLYA Salmonella Typhimurium Test?
Specimen include: all kinds of feed, food, seafood and medicine. Widely used in feed industry and food processing industry. You can choose the right products according to your needs.
Significance of testing Salmonella Typhimurium
To protect the animal have health feed, food, seafood and medicine, avoid contaminated food. The excess Salmonella typhimurium is harmful for animal being, can’t take too much in the body.
1. Take some feed or food specimen 2. Add the supernatant to cassette 3. Wait for 15 minutes to result 4. The details of operation, refer to the kit instruction
Limitations of BALLYA Salmonella Typhimurium Test?
BALLYA Salmonella Typhimurium Test is a qualitative test kit. It’s only for screening purpose. If have positive cases or suspected case, maybe use other detection method to make a further detection, such as, ELISA, PCR, qPCR, etc.
BALLYA Salmonella Typhimurium Test is suitable for the detection of microorganism residues, toxic and harmful substances and antibiotic residues in feed, food and medicine.
It can be widely used in food and drug administration, health departments, higher education institutions, scientific research institutes, agricultural departments, animal husbandry and veterinarians, breeding farms, slaughterhouses, food and meat products deep processing enterprises, inspection and quarantine departments and other units.
