Pharyngeal swab

Revealing the characteristics of flocking swabs

Everyone knows that when we go to the hospital for examination, the medical staff will use some medical aids to help us collect samples. The flocking swab is one of the common medical tools. Now let’s get some information about the flocking swab. Flocking swabs are mostly used for DNA extraction. They are made of nylon fiber flocking technology. The front end is coated with nylon short fibers fixed vertically, which makes no absorption holes in the whole collection area. DNA cells will not disperse and remain in the fibers, which is conducive to faster and more efficient elution. Flocking swabs are usually equipped with special national patent preservation sleeves. The swabs are suspended in the tube to prevent contamination due to packaging adhesion. The bottom of the tube is equipped with special filter membrane to ensure the air permeability inside and outside the tube, to prevent the mildew of the sample, and to filter out the small impurities in the external air that may affect the quality of the sample, so as to facilitate the long-term storage of the sample.

Characteristics and advantages of sampling swabs

Characteristics and advantages of sampling swabs

Sampling swab, also known as cervical sampling test, flocking cotton swab, is made up of nylon staple fibers and medical grade ABS plastic rods. The function of nylon staple fibers is like a soft brush, which can effectively improve the collection of cell materials. The capillary movement between fibers forms a strong hydraulic pressure, thus taking liquid samples. When the sample is close to the swab surface, it can be easily eluted. It can be used for bacteriological sample processing, virological cell culture, DFA test, rapid and direct test, enzyme immunoassay, polymerase chain reaction and molecular diagnosis-based detection.

Nylon flocking swabs are widely used and are ideal for bacteriological sample processing, virological cell culture, DFA testing, rapid and direct testing, enzyme immunoassay, polymerase chain reaction and molecular based diagnosis, as well as forensic identification. Similarly, flocking swabs can also be used for influenza, swine flu and avian influenza. Pharynx and throat sampling of respiratory viruses such as hand, foot and mouth.

Advantages of flocking swabs

Comparisons:

Nylon swab: Excellent sample collection/release capacity, release rate > 80%.

Conventional fibre swabs:

Samples are intercepted by interstices within the fibre mass, i.e. samples are infiltrated, diluted and intercepted in the fibre. Collection is slower and release is slower.

The sampling time of flocking swab is 3-5 seconds, while that of cotton swab is 15-120 seconds, or even longer, which causes the pressure of staff in the process of diagnosis. Only by extracting samples faster, can the collection and analysis be completed more efficiently.

Extraction of DNA from microbiological samples by Huachenyang flocking swab and composite nano-cotton swab. Methods Three kinds of carriers (glass, one-character knife and drawer handle) were selected and disinfected to simulate the microDNA samples on the surface of the carriers. The microDNA samples on the carriers were extracted by Huachenyang flocking swab and composite nano-cotton swab respectively to detect the number of STR loci, the number of alleles lost and the peak height area. As a comparison index of extraction effect. Results Five microDNA samples were successfully extracted from Huachenyang flocking swab and four were effectively detected. Nine microDNA samples were effectively detected from the microDNA sample group extracted by composite nano-swab. The number of allele loss in composite nano-swab group was significantly higher than that in Huachenyang iClean group, and the peak area was significantly lower than that in composite nano-swab group. Bright morning sun. Conclusion The DNA extraction effect of Huachenyang flocking swab is better than that of composite nano-cotton swab on the fingerprint of glass surface, the exfoliated cells on the surface of open knife and the exfoliated cells on the surface of drawer drawer.

China spread African swine fever and virus sample collection kit

According to the information Office room of the Ministry of Agriculture and Rural areas, from the beginning of August, China’s first outbreak of African swine fever began, the country has more than 10 provinces have found outbreaks, November 17, the latest release, Shanghai Jinshan to detect the outbreak of African swine fever: 50 pigs 11 deaths. African swine fever (ASF) disease is caused by the African swine Fever virus (ASFV), ASFV infects domestic pigs, warts pigs and South African wild boars.

The disease is transmitted through direct contact between healthy and diseased animals, or indirectly through infected feed, as well as through biological carriers (soft ticks). There are acute, acute, subacute and chronic forms of onset, in which the incubation period for acute diseases is short, about 3-7 days, accompanied by high fever (up to 42°c), and dies within 5-10 days.

Because of the different virulence of swine infection, the mortality rate ranges from 0% to 100%, and the outbreak of outbreaks in any region or country has a devastating effect on the local pig farming industry and related industries, but it has not been confirmed that ASF is at risk of infecting people.

Chinese officials have found the African Swine Fever Virus in some protein powders made from pork blood produced by a Chinese company. The General Administration of Customs issued a statement saying that the raw material in 79.93 tons of contaminated protein products, mainly used in animal feed, came from 12 slaughterhouses.

This happened in spite of the fact that Chinese health officials banned the use of food waste and pig blood as a raw material for the production of pig food. Officials implemented the ban in September in an effort to control the spread of the disease. China has already reported more than 90 cases of African Swine Fever virus infection, which is deadly to pigs but doesn’t harm humans.

China first detected the disease in its herds back in August. The customs department also has issued an alert, that will last for six months, to strengthen testing for the African Swine Fever virus in exports of similar products. The alert also urges farms in Hong Kong and Macau to tighten their checks on animal feed imports.

More than 200,000 pigs on infected farms have been culled, according to a Reuters tally of official figures, while hundreds of thousands more in the vicinity have also been put down.China has the world’s largest hog herd and the rapid spread of African swine fever has roiled the country’s trade in pork, the nation’s most popular meat, disrupting supplies and pushing up prices in some areas.

For the rapid spead of African swine fever, sample collection, detact & diagnstic kit is key point to control the fever. iclean virus collection flocked swab with transport medium is ideal for sample collection, transport of African swine fever in ambient temperature compatible to downstream application as qPCR, ELISA, colloidal gold detection card detection.
