The two common guinea pig fur mites are Trixacarus caviae (sarcoptic mange mite) and Chirodiscoides caviae. Chirodiscoides caviae mites may cause mild to no clinical signs at all. Trixacarus caviae mites can cause extreme clinical signs because they cause extreme itchiness. Affected skin will get thick, yellowish, and crusty, with hair loss and secondary bacterial skin infection. These mites cause such itchiness that your guinea pig may even go into seizures and die. Your veterinarian will treat the affected animal with topical or injectable anti-parasitic medications, and since mites live in the environment, the environment must be treated, as well. Trixacarus caviae mites are contagious to people.
Therapeutic laser is the application of light energy to areas of the body to stimulate healing. This light–tissue interaction is called photobiomodulation. In the past, therapeutic laser was often referred to as low-level or cold laser (as opposed to a surgical or hot laser).
