The generic name of VTM Virus Sampling Tube is a single-use virus sampling tube, which is generally used for the detection and sampling of infectious pathogenic microorganisms in disease control departments and clinical departments. It is suitable for detection and sampling of influenza viruses (including general influenza, highly pathogenic viruses, H1N1 influenza virus, etc.), hand, foot and mouth virus, new coronavirus, measles and rubella and other types of viruses. VTM virus sampling tube can also be used for detection and sampling of Mycoplasma, Chlamydia and Ureaplasma urealyticum.

The virus and related samples in the VTM virus sampling tube should be stored and transported within 48 hours in a refrigerated state (2-8°C). Viruses and related samples can be stored for a long time in -80℃ environment or liquid nitrogen environment. The virus can maintain the activity of the virus in a lower temperature range, reduce the speed of virus decomposition, and improve the positive rate of virus isolation.
The VTM virus sampling tube is generally equipped with a disposable flocking swab. From the appearance point of view, the flocking swab is white and soft. Using this soft brush during the sampling process will make the user feel no foreign body, and it is suitable for different Partial sampling person. Moreover, the flocking swab is designed with a breaking point that conforms to the length of the sampling tube and the natural orifice of the human body, which is not only convenient for sampling but also convenient for transportation of the specimen.
Feeding method for snake feed
1. Young snakes are fed with small prey that either hatch from eggs or are produced by the mother until their first hibernation. Snakes that are 1 to 3 days old typically do not require additional feeding, as they absorb nutrients from the yolk sac of the oocysts. By the time they reach 4 days of age, they enter an open feeding period. However, at this stage, their ability to actively seek out food is limited. To assist them, artificial feeding can be initiated by placing bait in areas where the young snake is active. Suitable prey includes small animals such as pups, small loaches, or tiny squids, which are small enough and have some movement. For weaker individuals, it's important to separate them from more aggressive feeders. In some cases, a tool like an ear syringe can be used to administer liquid feeds, such as egg mixtures or milk, directly into the snake’s mouth.
Feeding methods for young snakes should be done carefully. Large syringes must be sterilized before use, and then filled with a soft paste-like feed. The snake should be gently held, its mouth opened, and the feed slowly injected. Once the snake swallows, apply gentle pressure on the throat and rub downward to help digestion. The amount of feed depends on the size of the snake. Typically, each young snake receives between 10 to 20 grams per feeding, once a week. Studies have shown that this method increases survival rates by about 20% compared to natural feeding. Rats, when filled with meat and organs, can be used as a source of nutrition. On average, each larvae consumes 0.5 grams of feed every 10 days. After eight feedings before winter, the snake’s body length increased by 14.5%, and its weight rose by 14.9%.
2. As snakes grow larger, their body shape and weight increase rapidly. This stage is primarily focused on fattening the snakes for use in food or medicinal products. Feeding and fattening is only suitable for non-venomous snakes, as venomous species pose a risk during handling. This process usually begins around the fourth day after the second feeding post-hibernation, or earlier if the snake is being prepared for processing. It can also start 2 to 4 weeks before initial processing. At the beginning of this phase, the snake’s esophagus is narrow, making it difficult to consume large amounts of food at once. Therefore, it’s recommended to add 5% to 10% water to the feed mixture, turning it into a paste. Each feeding session should include approximately 100 grams of the softened material, and feedings should occur every other day.
After 3 to 4 feedings, and following a one-week gap, the esophagus gradually expands, allowing for daily feedings. At this point, each feeding should consist of 100 to 150 grams of wet feed. Feeding duration should be appropriate; if too long, it may lead to overfeeding. Usually, feeding continues for 15 to 20 days to prepare the snake for initial processing. Whenever possible, local slaughterhouse waste or locally available animals should be used as feed. If using various animal parts, internal organs, insects, or cockroaches, bones must be crushed to avoid damaging the snake’s esophagus. Crushed plant-based feed can also be added in quantities of 5% to 10%, ensuring even mixing before feeding.
