Lymphadenitis is the clinical term that is used to describe inflammation and swelling of the lymph nodes, which are located throughout the body -- head, neck, limbs, etc. -- and act to spread white blood cells and to filter infectious pathogens and foreign bodies that enter the body. The usual cause of lymphadenitis is bacterial infection, with the most frequently diagnosed bacterial infection in guinea pigs being Streptococcus zooepidemicus. Lymphadenitis requires immediate veterinary attention.
The usual cause for the development of lymphadenitis in guinea pigs is bacterial infection, most often Streptococcus zooepidemicus. Underlying factors include harsh or irritating food, unclean bedding material, and overgrown teeth or the inability to close the jaws properly. Guinea pigs can also acquire lymphadenitis from other infected guinea pigs that are sneezing or coughing, by genital contact, or through cuts or scrapes in the skin or in the mouth.
Your veterinarian can diagnose lymphadenitis by conducting a physical examination of the infected guinea pig, and by taking a fluid sample from the swollen glands. The causative bacteria can be confirmed only by doing an examination of stained smears that have been prepared from the infected tissue, and by other laboratory tests that will point your doctor toward the appropriate treatment. A blood profile will be conducted, with a complete blood count and a urinalysis. Increased levels of white blood cells, protein in the urine, or blood in the urine are all symptoms of an infection that needs treatment.
