摘　　要：Porcine Respiratory Disease Complex (PRDC) is one of the most important health concerns in swine production due to consumer demand for high quality pork from healthy animals. This study was conducted to characterize and compare the gross microscopic lesions and serological profiles of swine pneumonic lungs from selected slaughterhouses in Laguna, Philippines. Blood and lung samples were collected from the municipalities of Santa Cruz, San Pablo, Los Baños, and Cabuyao. Enzyme-Linked Immunosorbent Assay (ELISA) test was conducted for the blood samples and the histopathological changes in the lung tissues were observed microscopically. The results showed that the presence of Porcine Pleuropneumoniae (PPP), Enzootic Pneumoniae (EP) and Porcine Reproductive and Respiratory Syndrome (PRRS) virus were detected using ELISA. In Los Baños, Sta. Cruz and San Pablo the most prevalent disease was EP at 26.1%, 13.0% and 17.4% respectively. While in Cabuyao the diseases found were PRRS and EP, both at 8.7%. Based on the histopathological examination, it was found out that the most occurring types of lesions were hemorrhage, congestion and lymphoid hyperplasia of BALT (Bronchial Associated Lymphoid Tissue). However, the histopathological findings were found to be not significantly associated with the disease present in the sampled swine .
