What causes infection in a cat? - in detail
Infections in cats can arise from a variety of pathogens, including bacteria, viruses, fungi, and parasites. Bacterial infections, such as those caused by Pasteurella multocida or Staphylococcus, often result from wounds, bites, or underlying health conditions that compromise the immune system. Viral infections are another significant cause, with feline herpesvirus (FHV-1) and feline calicivirus (FCV) being common culprits, particularly in respiratory and oral infections. Feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV) are more severe, weakening the immune system and making cats susceptible to secondary infections. Fungal infections, such as ringworm (Microsporum canis), are highly contagious and typically affect the skin, hair, and nails. Parasitic infections, including those caused by fleas, ticks, mites, and intestinal worms, can lead to skin irritation, anemia, and gastrointestinal issues. Environmental factors, such as exposure to contaminated surfaces, other infected animals, or poor hygiene, can facilitate the transmission of these pathogens. Additionally, stress, malnutrition, and pre-existing health conditions can compromise a cat's immune defenses, increasing the likelihood of infection. Vaccination, regular veterinary care, and proper hygiene are essential in preventing and managing infections in cats.
