Refinements in housing during data capture in long term Safety Pharmacology dogs

Dogs are individually housed when collecting data for ECG studies to avoid any cross talk between transmitted signals (generally for a 24 hour recording period). Each implant is set at a certain frequency which transmits via radio frequency. Implants with...

Refinements to animal husbandry for continuous infusion dosing in Beagle dogs

At Envigo we are contracted by our customers to conduct studies, usually to evaluate the safety of new drugs and chemicals. A rodent and non-rodent species are usually involved in this testing with the method of administration designed to replicate...

Spider and chips: The use of internal Radio Frequency Identification (RFID) chips as a minimally invasive method to measure internal body temperatures in invertebrates

Internal RFID transponders have been used in vertebrates for many years, however studies into their use in invertebrates are less well represented in the literature. The use of RFID transponders for internal temperature measurement represents a less invasive alternative to...

The vest-collar as a rodent collar to prevent licking and scratching during experiments

Various types of restraint collars have been used for research animals, and the Elizabethan collar (E-collar) is the most commonly used. However, animals can be choked by the E-collar or they tend to remove it; furthermore, repeated rubbing and scratching...

Effects of group housing on ECG assessment in conscious cynomolgus monkeys

Assessing the cardiovascular safety of new chemical or biological entities is important during pre-clinical development. Electrocardiogram (ECG) assessments in non-human primate (NHP) toxicology studies are often made using non-invasive telemetry systems. We investigated whether ECG recording was feasible during group...

Versatile 3-D printed headstage implant for group housing of rodents

An unfavourable yet necessary side-effect of stereotaxic surgery involves the social isolation of post-surgery rats, in order to protect their wound site or skull-mounted implant from damage. Social isolation can cause a myriad of behavioural and physiological changes that are...
