Because of limited antimicrobial sensitivity, chloramphenicol (50 mg/kg, PO, bid) is the recommended treatment. An undercoat and projecting guard hairs make up the normal fur coat of a cavy. Similar organizations exist in Australia (Australian National Cavy Council)[116] and New Zealand (New Zealand Cavy Council). Foods high in calcium, eg, alfalfa hay, may result in a high dietary calcium:phosphorus ratio. Guinea Pigs Megan LaFollette 11/17/2020 no comments In a laboratory setting, it is important to provide housing that allows expression in a wide range of species-typical behaviors while also meeting the goals of the researcher. Some pet owners and veterinary organizations have advised that, as a legume rather than a grass hay, alfalfa consumed in large amounts may lead to obesity, as well as bladder stones from the excess calcium in all animals except for pregnant and very young guinea pigs. It is important to provide your guinea pigs with an environment that is interesting, varied and safe. [8], The animal's name alludes to pigs in many European languages. [63]:72–73 If they become pregnant after this has happened, the birth canal may not widen sufficiently, which may lead to dystocia and death as they attempt to give birth. [159] During World War II, the plastic surgeon Archibald McIndoe established the Guinea Pig Club at Queen Victoria Hospital, East Grinstead, Sussex, England as a social club and mutual support network for his patients, who were undergoing previously-untested reconstruction procedures. Females bear up to 13 young per litter (4 is average); gestation takes 68 days. Alternative “safe” antibiotics are azithromycin (15–30 mg/kg/day, PO; discontinue if soft feces) and fluoroquinolones; however, bacterial resistance to these antibiotics is now frequently seen. There are two other, similar syndromes in guinea pigs that affect either the skeletal muscles (muscular dystrophy) or the myocardium and skeletal muscles (muscular degeneration and mineralization). What is the typical life expectancy for a guinea pig? The inflammation can progress to osteoarthritis and systemic amyloidosis secondary to chronic staphylococcal infection. If introducing a pair or group to a new guinea pig, keep the pair/group together, then put the new guinea pig at the other side of the divider. A separate, incidental finding of multifocal mineralization of individual muscle fibers may be seen in major muscles of hindlimbs. [108], Guinea pigs are prey animals whose survival instinct is to mask pain and signs of illness, and many times health problems may not be apparent until a condition is severe or in its advanced stages. [74] The condition may be temporarily alleviated by a human carefully removing the impacted feces from the anus. T mentagrophytes can be isolated from the skin and fur in up to 15% of clinically normal guinea pigs. Dystocia and stillbirths are related to large fetuses, subclinical ketosis, and fusion of the symphysis pubis. The scientific name of the common species is Cavia porcellus, with porcellus being Latin for "little pig". Admittedly, there are no hard and fast rules – a vital factor in keeping guinea pigs is not just the gender of the individual animals but also their respective characters. With present standards of husbandry, rodent control, and good quality feed, the disease rarely occurs. [135] Ecuadorians commonly consume sopa or locro de cuy, a soup dish. [118][119] Allergic reactions following direct exposure to guinea pigs in domestic settings have also been reported. Awns and straw in the bedding can also cause foot punctures. Ear chewing and barbering are seen in group-housed guinea pigs that develop a social hierarchy. However, it has not been known when and where the animals have been introduced to Africa. The clinical signs include anorexia, inappetence, nasal and ocular discharge, dyspnea, and often sudden death (this could also include S pneumoniae and S equi zooepidemicus). [47] Groups of boars often chew each other's hair, but this is a method of establishing hierarchy within a group, rather than a social gesture. Allergic symptoms, including rhinitis, conjunctivitis, and asthma, have been documented in laboratory animal workers who come into contact with guinea pigs. Most guinea pig celebrations take place on the National Guinea Pig Day (Día Nacional del Cuy) across Peru on the second Friday of October. Clinical signs of pneumonia are dyspnea, wheezy breathing, sneezing, nasal discharge, and coughing. [136] It is a syncretistic event, combining elements of Catholicism and pre-Columbian religious practices, and revolves around the celebration of local patron saints.

[89] The guinea pig mother only has two nipples, but she can readily raise the more average-sized litters of 2 to 4 pups. The cysts contain clear, serous fluid and may reach 2–4 cm in diameter. Risk factors for human dermatophytosis are young guinea pigs and recent acquisition of a new guinea pig. The lateral saphenous vein and the cephalic vein are useful to draw small amounts of blood. 1. It takes around four weeks for a male to become sterile after being neutered. Diagnosis of the disease by plain radiography is difficult because of the similar opacity of ovarian cysts and abdominal neoplasms.

Animals; Blood Group Antigens* Guinea Pigs; Humans; Substances. [42], Domesticated guinea pigs thrive in groups of two or more; groups of sows, or groups of one or more sows and a neutered boar are common combinations, but boars can sometimes live together. Lice may be observed directly on hair shafts with a magnifying glass. While it is normal for guinea pigs to sneeze periodically, frequent sneezing may be a symptom of pneumonia, especially in response to atmospheric changes. [94], Toxemia of pregnancy (hypertension) is a common problem and kills many pregnant females. A rumbling sound is normally related to dominance within a group, though it can also come as a response to being scared or angry. Prior to the fall of the Berlin Wall, East Germany sold patients as unwitting guinea pigs in drug trials conducted on behalf of Western pharmaceutical companies, according to a TV documentary. Abdominal ultrasound allows differentiation by imaging the inner structure of the ovarian cyst. The uterus should be opened close to the bifurcation of the horns. While male genitals may look similar, with the penis and anus forming a similar shape, the penis will protrude if pressure is applied to the surrounding hair. These varieties vary in hair and color composition. [31] The picture dates from the same period as the oldest recorded guinea pig remains in England, which are a partial cavy skeleton found at Hill Hall, an Elizabethan manor house in Essex, and dated to around 1575.[31]. Like chinchillas, guinea pigs share unusual reproductive physiologic characteristics of hystricomorph rodents. Increased radiodensity of the affected tympanic bulla may be seen on radiographs. Because of zoonotic considerations and the potential for a carrier state, treatment is not recommended.
