Detecting calves that are persistently infected with bovine viral diarrhea virus (BVDV) is essential to disease prevention. Immunohistochemistry (IHC) performed on formalin-fixed, paraffin-embedded ear-notch samples is commonly used for surveillance detection of BVDV antigens. However, due to the low percentage of positive samples in most submissions, the current workflow often entails considerable time reviewing negative results.

- Neonatal calf diarrhea frequently leads to dehydration and metabolic acidosis, impacting calf mortality, growth, and productivity, prompting interest in technological disease detection.
- The study explored the relationship between saliva conductivity and pH with clinical and biochemical indicators in calves, assessing the health of 141 dairy-bred calves from one week old until 25 days or until they developed diarrhea.
- Results indicated that while saliva pH decreased in calves with diarrhea, saliva conductivity showed no correlation with diarrhea or dehydration, highlighting the complexity of hydration status assessments in these animals.
The diagnostic process for infectious disease diagnosis in animals.

Veterinary diagnostic laboratories provide a vast catalog of tests for infectious agents and often have multiple tests and testing modalities for individual pathogens. Understanding which test to select, which sample type is best, and which animal to sample in a population are critical factors for drawing appropriate conclusions and diagnosing a disease. Each diagnostic test has its inherent diagnostic sensitivity and specificity, and, in many situations, multiple tests may be required for proper interpretation.

To better understand the epidemiology and clinical relevance of PCV2 and PCV3, this study analyzed a dataset comprising diagnostic data from six veterinary diagnostic laboratories (VDLs) in the United States of America. The data comprised of polymerase chain reaction (PCR) test results, sample type, and age group for PCV2 and PCV3 submissions from 2002-2023.
