However, if the pancreas has been severely damaged, support care, including supplemental pancreatic enzymes should be given with each meal. Although this worm is more common in marmosets, they can also occur in tamarins. Two important viruses in callitrichids are Lymphochorionmeningitis and encephalomyocarditis. The rat and mouse are the host reservoirs for LCM, which causes anemia and hepatitis in affected monkeys. LCM may be seen in callitrichids kept in cities, apartment buildings or other areas where mice and rats occur.
Transmission is by aerosol route.
Encephalomyocarditis may occur most frequently in zoos, and also has a suspected host of rats and mice. A third virus, callitrichid hepatitis, may also occur. Toxoplasmosis occurs sporadically in callitrichids. Spirurid nematodes and thorny-headed worms can affect marmosets and tamarins, and are carried by cockroaches and coporaphageous beetles. Also, lead poisoning may occur in tamarins and marmosets kept in apartments and houses painted with lead-based paint.
