New Bolton Center PADLS


Pennsylvania Animal Diagnostic Laboratory System (PADLS) is a tripartite system which joins together the University of Pennsylvania, the Pennsylvania Department of Agriculture, and the Pennsylvania State University, and is dedicated to the health, safety and welfare of families here and abroad.

The Pennsylvania Animal Diagnostic Laboratory System (PADLS) was established by the Pennsylvania Animal Health and Diagnostic Commission (AHDC) in 1991 in order to provide rapid and accurate diagnostic assistance to veterinarians involved with food-fiber animals, equine, aquaculture and wildlife. PADLS exists for the purpose of protecting animals and humans from health threats by providing accurate diagnoses to assist Pennsylvania's agricultural community in controlling diseases to minimize economic loss.

In an effort to identify and prevent disease problems, PADLS seeks to accomplish the following objectives:

  • Provide an early warning for impending epizootics and rapid accurate identification of infectious disease.
  • Identify infectious and contagious diseases as quickly as possible by providing accurate diagnostic tests.
  • Identify chemicals and contaminants that threaten animal and human health, and agriculture.
  • Assist in the diagnosis of nutritional and metabolic problems.
  • Perform testing necessary to support federal and state regulatory programs.
  • Perform testing necessary for the export of animals and animal byproducts.

The three laboratories in PADLS include:

  • New Bolton Center Laboratory, affiliated with the University of Pennsylvania, School of Veterinary Medicine in Kennett Square
  • The Pennsylvania Veterinary Laboratory, a division of the Bureau of Animal Health and Diagnostic Services in Harrisburg
  • The Animal Diagnostic Laboratory, affiliated with Pennsylvania State University in University Park

The partnership of the two university laboratories in the PADLS mission provides a unique opportunity to integrate complementary research and teaching components. The combined resources and technical expertise of leading scientists at PADLS laboratories provide state-of-the-art diagnostic technology supporting veterinarians’ efforts to advance animal and public health initiatives and support producers in assuring a safe, secure, and abundant food supply.

Microbiology Laboratory-PADLS

  • PADLS MicrobiologyThe microbiology laboratory is separated into three subgroups: Clinical Microbiology, Molecular Microbiology, and PEQAP.

    Located in the Myrin Building on the New Bolton Campus, the Clinical Microbiology laboratory is equipped with the latest technology and a knowledgeable support staff to provide diagnostic microbiology testing. Consultation and field investigation are also available. Testing includes aerobic, anaerobic, and fungal culture, and antibiotic susceptibility testing. 

    Molecular Microbiology uses sophisticated techniques to isolate and identify viruses and bacteria including polymerase chain reaction (PCR) and real-time reverse transcriptase-PCR. These methods are commonly used to identify Avian Influenza, Salmonella spp., and Streptococcus equi (Strangles).

    In addition to standard microbiological testing, the microbiology laboratory also performs egg testing as part of the Pennsylvania Egg Quality Assurance Program (PEQAP) and the FDA Egg Safety Rule. Farms that participate in these programs demonstrate their concern about food safety and produce a quality egg which helps to assure consumer confidence in eggs.

    As part of PADLS, the microbiology laboratory supports PADLS' program objectives and mission. The combined resources and technical expertise of leading scientists at PADLS laboratories provide state-of-the-art diagnostic technology supporting veterinarians’ efforts to advance animal and public health initiatives and support producers in assuring a safe, secure, and abundant food supply.

Avian Pathology Laboratory-PADLS

  • Avian Pathology smallThe Avian Pathology service strives to provide the best possible diagnostic service to Pennsylvania and regional producers, hatcheries, service personnel, feed companies, and breeder companies. Over the past decade, the service has expanded to include pet bird cases submitted by regional veterinarian, pigeons, waterfowl and birds of prey cases submitted by local wildlife organizations, backyard poultry flocks, and exhibition/show birds. Services include avian necropsies, serologic testing, virus isolation, and PCR. The board certified veterinary staff is not only qualified to provide accurate diagnostics but also advise on the treatment, control, and eradication of infectious diseases. Avian field investigation also adds to the array of services available.

Toxicology Laboratory-PADLS

  • PADLS ToxicologyLocated in the Myrin Building on the New Bolton Campus, the toxicology laboratory is equipped with the latest technology and a knowledgeable support staff to provide full veterinary diagnostic toxicology services. Animals can be exposed to toxic chemicals in a number of ways: ingestion of contaminated feed or foreign objects, inhalation, or skin contact. Through identification of such toxic chemicals, the toxicology laboratory helps to diagnose and prevent toxicosis in agricultural animals, pets, and wildlife. In addition to toxins, the laboratory has the ability to identify the levels of nutritionally relevant compounds including metals and vitamin E in animal samples.

    As part of PADLS, the toxicology lab supports PADLS' program objectives and mission. The combined resources and technical expertise of leading scientists at PADLS laboratories provide state-of-the-art diagnostic technology supporting veterinarians’ efforts to advance animal and public health initiatives and support producers in assuring a safe, secure, and abundant food supply.
