During the pet raising period, have you ever encountered symptoms such as taking your dog to play and just a few days after returning home, and it started with diffuse and intermittent mucus diarrhea, accompanied by loss of appetite, nausea and vomiting, weight loss, and always wanting to sleep?
When inquiring about everyone, the symptoms of diarrhea and nausea and vomiting in dogs can basically account for one-third. Some causes of the disease are very easy to distinguish, but some causes of the disease must be deeply explored in order to find the culprit of diarrhea.
At the beginning of the article, people first responded to a question that everyone was very concerned about: Will Giardia be infected by dogs?
Giardia can infect most vertebrates including dogs, cats and people. It is a parasitic infection between humans and animals. In other words, it can theoretically be transmitted by cats and dogs, and it can also be transmitted by humans.
When you see this, you will turn your attention to your dog who has had a stomachache at home: "Will this guy continue to infect me?"
Everyone doesn't need to panic. Because Giardia with different genotypes has different host selectivity, people infected with Giardia are dominated by genotypes A or B, but genotypes C and D are found in dogs. Sometimes genotypes A are found, while genotype B is basically rarely found.
In other words, the chances of special genotypes of dogs and cats infecting people are extremely low, but people's genotypes will spread among dogs and cats (whether should you be happy or secretly happy or say Anmu Saori →_→).
Let's be at ease this time. Let's go to the main topic of the article. The complete collection of novice dog raising will take you to learn more about the symptoms, treatment and prevention of dog infection with giardia. Since it is a zoonotic disease, the symptoms and prevention standards are available to us as well, especially those who like to travel and run around (manual font bold). I hope everyone can read it carefully!
1. How does Giardia infect small animals?
Giardia has two shapes: cyst and moisturizing body. The cyst is the infected shape of Giardia. After the cyst enters the digestive system, it decapsulates the cyst to produce a moisturizing body. Part of it adheres to the colon and duodenum, and part of it moves to the intestines to convert into infectious cysts. It is excreted with excretion and returns to the natural environment to wait for the next host.
Therefore, there are three key ways to spread the infectious cysts of Giardia: water resource dispersion, food dispersion, and fecal oral transmission.
2. Symptoms of Giardia infection
According to scientific research materials, the overall incidence of Giardia in European dogs and cats is about 3-7%, but it is more likely to get sick in the following year, especially among young dogs and cats within 6 months, making it one of the common causes of diarrhea in this age group. Although most of them do not have any significant symptoms, subacute infections still show the following main symptoms:
1. Diffuse and intermittent mucous diarrhea;
2. Belly bloating;
3. Decreased appetite;
4. Nausea and vomiting;
5. Always want to sleep;
6. Poor mental substance;
7. Weight loss;
8. Some dogs may experience "secondary lactose intolerance".
3. The key to confirming giardiasis is the following methods
The key to confirming giardiasis includes antigen testing, DNA testing and excrement testing. Although excrement testing is simple and convenient, under the conditions permitted by the standards, novice dogs still strongly recommend nucleotide and antigen testing. Since generally, only subacute diarrhea can detect the moisturizing body of giardia in excrement. Most of the non-subacute diarrhea are cysts. This cyst is very small and will not move. Inexperienced pet doctors cannot detect it. This is the key reason why some pet clinics cannot detect giardiasis.
4. How to treat giardia infection
Since giardia is mostly invisible, generally speaking, even if the dogs and cats of giardia are found to be found, if the symptoms do not mainly show that the symptoms harm the dogs and cats themselves, they will not need to be treated.
However, if the positive type of Giardia vermin is tested, and the symptoms are accompanied by the above symptoms, the surgery should be performed. However, the treatment of Giardia vermin is to remove clinical manifestations rather than to completely remove pathogens. In the future, the infection may occur again. Therefore, the pet owner should make full preparations for dogs to have Giardia vermin. The following two drugs are for reference only. In fact, please follow the doctor's advice:
1. Fenbendazole: 50mg/kg rest weight, once a day, and continue;
2. Metronidazole: 25mg/kg rest weight, twice a day, and continue for five days.
5. Why is it difficult to eradicate the Giardia?
1. Giardia is easy to attack. The key reason is that their capsules have strong resistance to the external natural environment. A small amount of capsules can cause small animals to be infected again;
2. Giardia will become resistant to some drugs. After the attack, the actual effect of continuously applying the same drug will become worse and worse;
3. Immunodeficiency disease or secondary diseases will increase the difficulty coefficient of Giardia.
Although the attack after reasonable original treatment may be reinfection, in many cases, it is the result of Giardiasis itself, such as secondary lactose intolerance after illness, some digestive and absorption obstacles and irritable bowel syndrome, etc..
6. How to prevent giardia, what is the use of dog deworming medicine?
When seeing this, many people have the following doubts: Since Giardia can cause diarrhea to dogs, can common dog deworming drugs be prevented? Is there any relative prenatal?
Many Although the mainstream product dog deworming drugs have certain practical effects, and because the excessively unique characteristics of Giardia cannot be completely prevented or driven away, then again, if it is not sick, it will not easily cause damage to the dog. Therefore, dogs without diarrhea and other diseases do not have to worry even if they are found in excrement. Like candida coccidi, Giardia flagellia has little practical significance for purpose prevention, and the pre-seeding is not perfect. Just clean the dog itself and the natural environment. People should be more concerned about which situation is suspected that the dog's diarrhea is Jiadi. Caused by insect disease:
1. I had a long-distance trip before diarrhea, such as driving my dog to a suburb for an outing in the suburbs last or last Sunday;
2. Before diarrhea, there was precipitation and rain in the big city, and the water content in the puddles is complicated, and dogs licking and sucking are very likely to cause infections such as Giardia;
3. Before diarrhea, there were long-distance freight, such as dogs shopping online, especially dogs with "fair price", their living environment can be described as "terror". Demodex mites, bacteria, various larvae, etc. are likely to be infected by dog dealers.
4. Dogs like to eat randomly, and even often touch other dogs' excrement close-up.
The research process of Giardia is relatively symbolic. It took 300 years from discovering and scientifically studying its existence and life characteristics to the entire process of onset of the disease. For 300 years here, everyone's understanding of Giardia has been "destroying" and "reconstructing". Therefore, please diversify your logical thinking: whether it is a pet or a person's disease, there are often many situations that cannot be expressed in current medical common sense, and it is very likely to defeat people's current understanding in the future.
