The signs of effusive form of FIP usually develop and progress relatively rapidly and include development of the above-mentioned non-specific signs combined with the accumulation of fluid in body cavities, including the abdomen and the thorax (chest cavity). Generally speaking, the signs of the noneffusive form, which may include the non-specific signs listed above as well as neurologic signs including seizures and ataxia (abnormal or uncoordinated movements) develop more slowly than those of the effusive form. It is also important to note that cases of the effusive form of FIP can evolve into the non-effusive form and vice-versa. Regardless of which form they ultimately progress to develop, cats infected with FIPV usually first develop nonspecific signs of disease such as loss of appetite, weight loss, depression, and fever. There are two major forms of FIP, an effusive, or “wet” form and a noneffusive, or “dry” form. Only a small percentage of cats that are exposed to the FeCV develop FIP, and this can occur weeks, months, or even years after initial exposure to FeCV. In most cases, these mild signs are self-limiting. Some cats may show mild upper respiratory symptoms such as sneezing, watery eyes, and nasal discharge, while others may experience mild gastrointestinal signs such as diarrhea. To our knowledge, coronaviruses cannot be passed from infected cats to humans.Ĭats that have been initially exposed to FeCV usually show no obvious symptoms. Once a cat develops clinical FIP, the disease is usually progressive and almost always fatal without therapy that has recently become available, but that has yet to be approved to treat FIP in cats by the Food and Drug Administration (FDA) (see below). It is this interaction between the body’s own immune system and the virus that is responsible for the development of FIP. An intense inflammatory reaction to FIPV occurs around vessels in the tissues where these infected cells locate, often in the abdomen, kidney, or brain. ![]() When this occurs, the virus is referred to as the FIPV. In approximately 10 percent of cats infected with FeCV, one or more mutations of the virus can alter its biological behavior, resulting in white blood cells becoming infected with virus and spreading it throughout the cat’s body. FeCV-infected cats usually mount an immune response through which antibodies against the virus are produced within 7-10 days of infection. Cats infected with FeCV usually do not show any symptoms during the initial viral infection, but may occasionally experience brief bouts of diarrhea and/or mild upper respiratory signs from which they recover spontaneously. These are referred to as feline enteric coronavirus (FeCV). Most strains of feline coronavirus are found in the gastrointestinal tract and do not cause significant disease. Lung Ailments: A Widespread Source of Feline Woeįeline infectious peritonitis (FIP) is a viral disease of cats caused by certain strains of a virus called the feline coronavirus. Only a few congenital heart defects cause cyanosis.FIP VIDEO - therapeutic targets and better diagnosis Some heart defects are also caused for no apparent reason at all. Issues with maternal health, such as underlying and poorly controlled type 2 diabetes, can also result in a baby developing heart defects. For example, babies born with Down syndrome often have heart problems. Genetics cause most congenital heart defects. Methemoglobinemia can also rarely be congenital. This gives babies with the condition their bluish hue. While methemoglobin is oxygen-rich, it doesn’t release that oxygen into the bloodstream. As nitrite circulates in the body, it produces methemoglobin. When this young, babies have more sensitive and underdeveloped gastrointestinal tracts, which are more likely to convert nitrate into nitrite. The condition occurs most often in babies under 6 months of age. It is can happen in babies who are fed infant formula mixed with well water or homemade baby food made with nitrate-rich foods, like spinach or beets. This condition stems from nitrate poisoning. TOF includes conditions like having a hole in the wall that separates the left and right ventricles of the heart and a muscle obstructing the flow of blood from the right ventricle into the pulmonary, or lung, artery. It’s actually a combination of four heart defects that can reduce blood flow to the lungs and allow oxygen-poor blood to flow out into the body. ![]() While a rare congenital heart defect, TOF is a primary cause of blue baby syndrome. ![]() The lack of oxygenation can occur for several reasons. This causes the skin to take on a blue color. When there’s a problem with the heart, lungs, or blood, blood may not be oxygenated properly. The blood is circulated back through the heart and then throughout the body. Normally, blood is pumped from the heart to the lungs, where it receives oxygen. The baby takes on a bluish hue because of poorly oxygenated blood.
