Embryos from the guinea pig (Cavia porcellus) have been used in various tetragenic studies, including the effects of elevated body temperature on embryonic development. Postnatally guinea pigs can become sexually mature as early as four weeks.
Historically, it was the Spanish conquistadors who approximately 400 years ago brought guinea pigs to Europe from South America, where they are native.
Nutritional research using guinea pigs showed that scurvy was due to a lack dietary vitamin C, and they have also been used for other dietary requirement studies.
The guinea pig middle ear ossicles, malleus and incus, are a single fused complex, compared to humans where they are two separate bones.

Hyperthermia and Development
Guinea pigs have been successfully used as a sensitive model system for the effects of maternal hyperthermia (high body temperature/fever) upon development. This is an excellent example of a maternal environmental effect on embryonic development and neurological effects have also been demonstrated in other rodent model systems. (More?

Cawdell-Smith J, Upfold J, Edwards M, Smith M. Neural tube and other developmental anomalies in the guinea pig following maternal hyperthermia during early neural tube development. Teratog Carcinog Mutagen. 1992;12(1):1-9. "Guinea pigs were exposed to hyperthermia for 1 hr once or twice on day 11, 12, 13, or 14 (E11-E14) of pregnancy. The mean rectal temperatures were elevated by 3.4 degrees C-4.0 degrees C. This treatment resulted in a marked elevation of rates of resorption and developmental defects in embryos examined at day E23. The defects observed were those affecting the neural tube (NTD) (exencephaly, encephaloceles, and microphthalmia), kyphosis/scoliosis, branchial arch defects, and pericardial edema. Embryos with NTD and kyphosis/scoliosis have not been found among newborn guinea pigs to date following maternal heat exposure on days E12-E14. It appears that embryos with these defects are filtered out by resorption or abortion by days E30-E35." (More? see Marsh Edwards | Upfold etal., 1989)
Guinea Pig Research Characteristics
The following lists reasons why the guinea pig is an excellent model animal system for development studies.
- Long Gestation Period With Mature Central Nervous System at Birth - toxicology and teratology studies.
- Sensitivity of Respiratory System - asthma and environmental pollution studies.
- Anatomy of the Guinea Pig Ear - inner ear studies because it is easily dissected and exposed.
- Vitamin C Requirement - wound healing. bone, tooth and atherosclerosis studies.
- Guinea Pig serum - Possesses hemolytic complement with higher activity levels than other lab animals. Widely used as a source of complement for complement fixation test.
- Susceptibility to Infectious Diseases - sentinel animals because of their acute susceptibility to Coxiella burnetii., Mycobacterium sp. and Listeriosis.
- Similar lmmune System to Man - immune system possesses a similar antigen-macrophage interaction to man and delayed cutaneous hypersensitivity reaction.
- High Dietary Requirements - folic acid, thiamine, arginine and potassium make guinea pigs useful in nutrition studies.
- Precocious Young - good for germ free raising.
- Quiet Calm Disposition - entomology studies, used to test repellents and insecticides, and as feeding source for biting insects.
