Major cause of chronic respiratory disease in rats and mice.
Caused by Mycoplasma pulmonis.
CS: asymptomatic at first to sneezing, snuffling, squinting, and prophyrin staining (rust colored) around the eyes and nose, signs of inner ear infection. Lower respiratory tract infection= bronchiolitis, bronchiectasis, and bronchopneumonia= rattling moist breath sounds, labored breathing, gasping, chattering and coughing, hunched posture, rough hair coat, weight loss, and behavioral changes.
Can also cause genital infections.
TX: Tylosin, Tetracyclines (Tetracycline, Doxycycline, or Minocycline) or Enrofloxacin.
One of the most common diseases in domestic rabbits.
CS: Usually associated with the upper respiratory tract. Watery nasal discharge, sneezing, then thick, whitish to yellowish nasal discharge, loud snuffling or snoring sounds, discharge in paws (from cleaning face), conjunctivits, orcular discharge, possible ear infections, torticollis (wryneck), head shaking, scratching, circling, disorientation.
TX: Enrofloxacin, Ciprofloxacin, and Trimethoprim sulfa.
AKA Parrot Fever, ornithosis, or chlamydiosis.
From Chlamydophila psittaci.
Zoonotic!! Also seen in cows, cats, goats, sheep, and pigs.
CS: No specific signs. Lack of appetite, weight loss, depression, listlessness, difficulty breathing, watery green droppings, pink eyes, discharge from eyes or nares, or sudden death.
Previously known as murine parainfluenza virus type 1.
RNA virus of the Paramyxoviridae family.
Highly transmissible respiratory tract infection of mice, hamsters, guinea pigs, rats, and occasionally pigs and marmosets.
CS: sneezing, hunched, posture, respiratory distress,
porphyrin (rust colored) discharge from eyes and/or nose, lethargy, failure to thrive in young, and anorexia.
Mice, rabbits, guinea pigs, hamsters, gerbils, rats, and highly fatal in foals, and wildlife.
Young, especially those fed high-protein diets, during periods of stress.
CS: Foals can be asymptomatic until coma or death. Depression, anorexia, pyrexia, jaundice, diarrhea, and recumbency, convulsions, coma, ruffled coat. Lesions seen in the liver, myocardium and intestinal tract- white, gray, or yellowish foci of necrosis.
Viral infection of swine and zoologic mammals.
CS: Sudden death at any age from myocardial failure, near-term abortions, fetal mummification, and apparent reproductive failure. Encephalotropic and cardiotropic strains. Cardiac signs most common: Sudden death with pulmonary edema, and frothy transudation into the respiratory tract. Fever, anorexia, listlessness, trembling, staggering, dyspnea, and paralysis.
Part of normal flora.
Immunocompromised or stressed animals can develop disease.
CS: Anorexia, vomiting, weakness, dehydration, diarrhea, black, bloody stool, abdominal pain, weight loss, pallor of MM, and poor hair coat or hair loss.
TX: Supportive care.
Bacterial septicemia that infects mammals (esp. rabbits), birds, reptiles, fish, and people.
Sheep are the most severely affected livestock. Sheep and cats may be subclinical or develop bacteremia, fever, and respiratory infection. Cats may also develop ulceroglandular or oropharyngeal disease. Increased HR and RR, coughing, diarrhea, pollakiuria with lymphadenopathy and hepatosplenomegaly. Prostration and death may occur within a few hours or days. Lesions: white to off-white foci of necrosis in the liver and sometimes the spleen, lung, and lymph nodes.
TX: Streptomycin, gentamicin, and tetracyclines.
Which statement concerning eye position, pupil size, and responsiveness to light as indicators of anesthetic depth is least accurate?
-In stage II, plane 3 of anesthesia, the eyes are usually central to slightly eccentric, with normal pupils that are responsive to light.
-In stage III, plane 2 of anesthesia, the eyes are usually rotated ventrally with slightly dilated pupils.
-In stage II of anesthesia, the eyes are usually central, and the pupils may be dilated and responsive to light.
-In stage IV of anesthesia, the eyes are central with widely dilated pupils that are unresponsive to light.
