弓形虫病是一种让许多猫主人担心的疾病。在本文中，我们将仔细研究家猫是否患上弓形虫病、它是如何发生的、要寻找哪些迹象以及如何保护猫和人。通过了解这一点，我们可以照顾好我们的猫科动物朋友，也可以保证自己的安全。
什么是弓形虫病？
弓形虫病是一种感染。它是由一种微小的寄生虫引起的。这种寄生虫的名字是刚地弓形虫。这种寄生虫非常小。你不能只用眼睛看到它。它需要显微镜才能看到。
这种寄生虫可以生活在许多动物体内。猫是刚地弓形虫的主要宿主之一。当寄生虫在猫的体内时，它会引起问题。但并非所有猫在感染这种寄生虫时都会表现出生病的迹象。
刚地弓形虫的生命周期很复杂。它有不同的阶段。其中一些阶段发生在猫体内。其他阶段可能发生在环境或其他动物中。了解生命周期有助于我们了解猫如何感染弓形虫病以及它如何传播给其他动物，包括人类。
猫是如何感染弓形虫病的
吃受感染的猎物
猫是天生的猎人。他们喜欢捕捉和吃小动物。小鼠、鸟类和其他小生物可能会感染刚地弓形虫。当猫捕捉并吃掉受感染的猎物时，它会感染寄生虫。
寄生虫在猎物的体内。当猫吃掉猎物时，寄生虫就会进入猫的身体。然后它开始在猫体内生长和发展。这是猫，尤其是那些外出打猎的猫，感染弓形虫病的常见方式。
摄入受污染的材料
猫也可能通过吃或舔被污染的东西而感染弓形虫病。例如，如果猫的食物或水碗靠近有寄生虫猫粪的地方，食物或水可能会受到污染。当猫吃或喝碗里的奶时，它会摄入寄生虫。
土壤也可能是污染源。如果土壤中有寄生虫，可能是因为受感染的猫在那里排便，那么在土壤上行走然后舔爪子的猫可以将寄生虫带入体内。
猫刚地弓形虫的生命周期
卵囊阶段
当猫感染刚地弓形虫时，寄生虫会在体内经历不同的阶段。重要的阶段之一是卵囊阶段。猫摄入寄生虫后，它开始在猫的肠道中繁殖。
寄生虫形成卵囊。这些卵囊非常小。它们通过猫的粪便排出体外。一旦进入环境，卵囊就不会立即具有感染性。他们需要一些时间来发展。此开发通常需要几天时间。在此期间，卵囊发生变化并变得更加危险。
组织囊肿阶段
猫体内寄生虫的另一个阶段是组织囊肿阶段。猫摄入寄生虫后，一些寄生虫可以传播到猫身体的其他部位。它们可以进入肌肉、大脑和其他器官。
在这些组织中，寄生虫形成包囊。这些囊肿可以在猫的体内停留很长时间。如果猫的免疫系统很强，它可以防止囊肿造成太多问题。但是，如果猫的免疫系统变弱，包囊就会打开，寄生虫就会再次开始繁殖，导致猫生病。
弓形虫病在家猫中有多常见？
患有弓形虫病的家猫数量可能会有所不同。在某些地区，它可能更常见。在其他情况下，它可能不太常见。
户外猫更容易患弓形虫病。他们有更多机会捕食受感染的猎物并接触受污染的土壤或其他材料。室内猫也可能患上弓形虫病，但它们的风险较低。这是因为他们不太可能接触到寄生虫的来源。
生活在收容所或多猫家庭中的猫可能具有更高的风险。在这些地方，携带寄生虫的猫咪可能更多，传播的机会也更大。例如，如果收容所里的一只猫患有弓形虫病并在猫砂盆中排便，其他猫可能会接触到受污染的粪便。
猫弓形虫病的症状
在 Kittens 中
小猫更容易出现弓形虫病的症状。与成年猫相比，它们的免疫系统较弱。小猫的一些常见症状是发烧、食欲不振和腹泻。
小猫的眼睛也可能有问题。他们的眼睛可能有炎症。这可能会导致他们难以看清。在某些情况下，患有弓形虫病的小猫可能会出现神经系统问题。他们可能会站不稳或癫痫发作。
In Adult Cats
Adult cats with strong immune systems may not show any symptoms at all. But if their immune system is weak, they can get sick. Symptoms in adult cats can include respiratory problems. They may cough or have trouble breathing.
Adult cats may also have problems with their digestive system. They may vomit or have diarrhea. Just like kittens, adult cats can also have eye problems and neurological problems if the infection is severe.
Diagnosis of Toxoplasmosis in Cats
Blood Tests
One way to diagnose toxoplasmosis in cats is through blood tests. The vet will take a sample of the cat’s blood. The blood is then tested for antibodies. Antibodies are things that the cat’s body makes to fight the parasite.
If the blood test shows that there are a lot of antibodies, it may mean that the cat has been infected with Toxoplasma gondii. But it’s not always easy to tell. Sometimes, the cat may have been infected in the past, and the antibodies are still in its blood. The vet may need to do more tests to be sure.
Fecal Tests
Fecal tests can also be used to diagnose toxoplasmosis. The vet will take a sample of the cat’s feces. The feces are looked at under a microscope. The vet is looking for the oocysts of the parasite.
Finding oocysts in the feces means that the cat is currently shedding the parasite. But oocysts are not always easy to find. Sometimes, the cat may not be shedding oocysts at the time of the test, so the test may come back negative even if the cat has the infection.
Treatment of Toxoplasmosis in Cats
Medications
If a cat is diagnosed with toxoplasmosis, the vet will usually prescribe medications. These medications are meant to kill the parasite or stop it from growing. Some common medications used to treat toxoplasmosis in cats are clindamycin and sulfadiazine.
The cat needs to take the medications as directed by the vet. The treatment may take a few weeks. During this time, the cat may need to be monitored closely to see if the medications are working and if there are any side effects.
Supportive Care
In addition to medications, cats with toxoplasmosis may need supportive care. If the cat has diarrhea or is dehydrated, it may need fluids. The fluids can be given orally or through an IV. If the cat has a loss of appetite, the owner may need to find ways to get the cat to eat. This could mean trying different types of food or feeding the cat smaller meals more often.
Risks to Humans from House Cats with Toxoplasmosis
Pregnancy Risks
Pregnant women need to be very careful around cats with toxoplasmosis. If a pregnant woman gets infected with Toxoplasma gondii, it can be very dangerous for the unborn baby. The parasite can cross the placenta and infect the baby.
This can cause problems like blindness, deafness, and neurological problems in the baby. Pregnant women should avoid cleaning litter boxes if possible. If they have to clean the litter box, they should wear gloves and wash their hands well afterward.
Immunocompromised People
People with weak immune systems, like those with HIV/AIDS or those taking medications that weaken the immune system, are also at risk. Toxoplasmosis can cause serious illness in these people. They may have more severe symptoms, like encephalitis (inflammation of the brain) or pneumonia.
These people should also take precautions around cats. They should make sure the cat’s living area is clean and that they don’t come into contact with cat feces.
Prevention of Toxoplasmosis in House Cats
Keep Cats Indoors
One of the best ways to prevent cats from getting toxoplasmosis is to keep them indoors. Indoor cats are less likely to hunt infected prey or come into contact with contaminated soil. They are also less likely to be exposed to other infected animals.
If you have an indoor-outdoor cat, try to limit its outdoor time. And when it does go outside, supervise it. This can help reduce the risk of the cat getting infected.
Clean Litter Boxes Regularly
Litter boxes should be cleaned daily. This helps to get rid of any cat feces that may have the parasite. If the litter box is not cleaned, the oocysts in the feces can develop and become infective.
Wear gloves when cleaning the litter box. After cleaning, wash your hands well with soap and water. This can help prevent you from getting infected if there are any parasites in the feces.
Feed Cats Commercial Food
Feeding your cat commercial cat food can help prevent toxoplasmosis. Commercial cat food is usually processed in a way that kills any parasites that may be in the ingredients. Avoid feeding your cat raw meat or unpasteurized milk. These can be sources of the parasite.
Test New Cats
If you are getting a new cat, have it tested for toxoplasmosis. This can help you know if the cat has the infection before you bring it into your home. If the cat is infected, you can take steps to treat it and prevent the spread of the parasite to other cats in your home.
In conclusion
House cats can have toxoplasmosis. But by understanding how they can get it, what the symptoms are, how to diagnose and treat it, and how to prevent it, we can keep our cats healthy. We can also protect ourselves and our families from the risks of this parasite. Taking these steps can help us have a happy and healthy life with our feline friends.
