Causes
Hookworms are parasiticParasitic refers to diseases or conditions caused by parasites. Parasitic infections can affect the digestive tract, skin, and other organ systems. nematodes that infest the digestive tract of cats. The most common species that infect cats are Ancylostoma tubaeforme and Ancylostoma braziliense. These worms are distributed worldwide and are particularly common in warm and humid climates.
The adultThe term "adult" refers to an individual who has reached full physical development and is considered an adult. In veterinary medicine, this term is used to describe animals that have completed growth and are of reproductive age. worms attach to the lining of the small intestineThe intestine is the medical term for the gut, including the small intestine (intestinum tenue) and the large intestine (intestinum crassum). It plays a central role in the digestion and absorption of nutrients., where they feed on blood and tissue.

Diagnosis
The diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. of ancylostomiasis is usually made through a microscopic examination of a stool sample from the cat. This involves identifying hookworm eggs in the feces. This method is reliable and allows for an accurate determination of the worm species.
In some cases, a blood testA blood test is a laboratory procedure in which blood is drawn and analyzed to obtain information about the body's health. It can include various parameters such as blood sugar, blood count, liver and kidney values. may be performed to evaluate the extent of the anemia and the cat’s overall health. A complete blood count can provide information about the degree of anemia and possible further infections.
Additionally, a physical examination by the veterinarian can help identify other clinical signs of the infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease., such as pale mucous membranes or skin irritation.
