Lizard and Snake Day to Day Practice

Day to day practice

Upon the entry into the quarantine area the keeping of records for individual animals should begin. Identification is extremely important for this to be successful.

Hygiene

Hygiene is probably the most important part of a preventive medicine program and includes attention to food and water, personnel and the environment. A food preparation area (especially one for humans!) should never be used cage cleaning. Maintaining personal hygiene will also help reduce the likelihood of a zoonosis. Sterilisation of the environment is not possible but the frequent use of disinfectants is extremely important in addition to the vigorous removal of faeces and other debris.

Vector control

Preventive medicine includes elimination of mechanical and biological vectors. For instance the snake mite has been incriminated in the spread of viral diseases and Aeromonas hydrophila. Flies, ticks and ants are potential vectors for disease. The eradication method must be effective against the vctor but safe for snake. For instance the vapours from dichlorvos strips can be potentially toxic to reptiles.

Formite control

When moving between cages or exhibitions it is possible to transfer organisms between snakes. Care must be taken to minimise transfer of disease by formites.

Prophylactic treatments

Prophylactic treatments are especially important in quarantine but may be useful on a regular basis. For snakes parasiticides are probably the most important.

Vivarium disinfectants

Chemical	Trade Name	Safe or Toxic	Comments
Phenol/Cresol	Lysol	Toxic	Effective against acid fast bacteria, less so against fungi, no effect against spores.
Quaternary ammonium compounds	Ark-Klens / Cetrimide	Safe	Effective, broad antibacterial activity. Poor efficacy against spores, viruses and fungi. Inactive in presence of soap.
Chlorhexidine	Hibitane	Safe	Effective, broad spectrum activity in presence of organic matter and other antiseptics. Inactive in presence of soap.
Hypochlorites	Milton	Safe	Unstable in solution and repeated use may cause skin irritation and burns.
Iodophores	Tamodine-E / Betadine / Povidon-iodine	Safe	Good against gram positive and negative bacteria, viruses and spores. Poor against acid fast bacilli and spores. Solution active as long as brown colour remains.
Dodecyclo-di-glycine	Amprotect	Safe	Good spectrum of activity against gram positive and negative bacteria, fungi and viruses.
Formaldehyde	-	Toxic	Poisonous but can be used to disinfect empty vivaria.
