The leatherback sea turtle (Dermocheleys coriacea) is considered an endangered species here in the Philippines and around the world. In Northern Samar, a leatherback sea turtle reportedly found by local fisher folks along the rocky mangrove and coral reef areas was placed in a rescue confinement for treatment and observation. Upon retrieval, the left fore flipper was already missing and the lacerated, amputated area was then bleeding. Treatment to arrest hemorrhage was performed and antimicrobials were administered. Two days thereafter, the animal succumbed to death. Because the animal was recovered a day following a typhoon that hit the province, it was inferred that the injury might be attributed to calamity-induced trauma as the animal was recovered as it was trapped along the rock-strewn mangrove areas. Following death, necropsy examination presented findings of severe congestive pneumonia, hemorrhages along the intestinal serosa, severe hepatic congestion, pericarditis and pronounced disseminated intravascular coagulopathy. The prominent histopathological finding of sub-acute severe hemorrhagic pneumonia with infiltrates of mononuclear cells, red blood cells, hemosiderins and proteinaceous debris were discerned along the lung parenchyma. The hepatocytes are swollen, distended and some presented congestion and necrosis. The intestinal sub-mucosae are infiltrated with mononuclear cells. Smears from blood and liver showed variable Gram-negative organisms. It was impressed that the animal may have been suffering from an underlying subclinical septicemic infection even prior to traumatic injury. These findings underscore the need to further study the microbial profile of this endangered species and provide means to mitigate occurrence of septicemia cases that could further exacerbate its dwindling populace. This index case of septicemia affecting a leatherback sea turtle has been reported for the first time in the country.

Eurasian otters Lutra lutra are listed as Near Threatened on the IUCN Red List and are imperiled by habitat loss, water pollution, and poaching. Harassment and attacks by stray animals are also recognized threats to the health of wild Eurasian otters. Pulmonary hair embolism is a possible complication in animals with deep traumatic injury, but to date no cases have been reported in wildlife. A free-ranging, adult male Eurasian otter was rescued due to severe emaciation and multiple bite wounds. The otter died 3 d after rescue and was necropsied. Grossly, a 1.5 × 1.5 × 1.5 cm firm nodule was observed in the left cranial lung lobe. Histologically, a fragment of hair shaft surrounded by multinucleated foreign body giant cells was observed in a medium-sized vein, and extensive eosinophilic infiltration was noted in the adjacent vascular wall and lung parenchyma. Based on the gross and histological findings, the pulmonary lesion was consistent with eosinophilic pneumonia and vasculitis induced by hair embolism. The presence of well-formed multinucleated foreign body giant cells and eosinophils may imply a late stage of foreign body reaction, and thus the presumptive source of hair embolism is an animal bite. This is the first report of pulmonary hair embolism associated with animal bite in a rescued free-ranging Eurasian otter.

Background: β-Adrenergic agents suppress inflammation and may play an important role in posttraumatic infections. Mechanisms may include inhibition of MAP kinase signaling. We sought to determine whether MKP-1 contributed to catecholamine suppression of innate immunity and also wanted to know whether early catecholamine treatment after traumatic injury increases the risk of later nosocomial infection. Methods: We performed experiments using THP-1 cells and peripheral blood mononuclear cells from healthy individuals. We exposed cells to epinephrine and/or LPS and measured inflammatory gene transcription and MAP kinase activation. We inhibited MKP-1 activity to determine its role in catecholamine-induced immune suppression. Finally, we studied injured subjects to determine whether early catecholamine treatment was associated with nosocomial infection. Results: Epinephrine increases MKP-1 transcripts and protein and decreases LPS-induced p38 and JNK phosphorylation and TNF-α gene transcription. RNAi inhibition of MKP-1 at least partially restores LPS-induced TNF-α gene expression (p = 0.024). In the clinical cohort, subjects treated with β-adrenergic agents had an increased risk of ventilator-associated pneumonia (aOR = 1.9; 95% CI = 1.3–2.6) and bacteremia (aOR = 1.5; 95% CI = 1.1–2.3). Conclusions: MKP-1 may have a role in catecholamine-induced suppression of innate immunity, and exogenous catecholamines might contribute to nosocomial infection risk.

ABSTRACT The January 7, 1994, barge Morris J. Berman grounding and oil spill off Punta Escambrín, near San Juan, Puerto Rico, resulted in injury to natural resources along the shoreline and impaired their use for an extended time. Three major injury categories were pursued by the Trustees and the restoration projects for these injuries are presented in this paper. Including interest, approximately $10M in settlement funds are being used to fund 6 restoration projects. About $6 million of the settlement funds is being used for three projects to restore eolianite reef habitat, a type of fossilized sand dune, and other reef resources injured by the barge grounding and subsequent spill. One project, called the Condado Coral Trail project, will install artificial reef modules in the Condado Lagoon, approximately 1 mile southeast of the barge grounding site. Also in the Condado Lagoon, a 32-acre dredge hole will be brought back to historic elevations through beneficial use of dredged marine sediments. The third reef project entails acquisition of shoreline and coastal property which is intended to provide reef resource services comparable to those lost as a result of the oil spill and grounding. This parcel provides habitat for over 40 rare species of plants and animals including a major nesting beach for the endangered Leatherback Sea Turtle. The acquisition project also serves as the sole compensatory restoration project for lost recreational beach use. The parcel is being designated as a Puerto Rico Natural Reserve thereby allowing the public to use the land, including its unspoiled beaches, for recreational purposes. Finally, three restoration projects are being implemented to compensate for the lost historic visitor use services at the San Juan National Historic Site. More than 123,000 visitors to the El Morro and San Cristobal forts were affected by the spill for approximately six weeks. The first of the three projects includes Improving and Extending the Coastal Promenade, a walkway at the base of El Morro. The second is restoration of El Morro Water Battery and the third is cleaning and stabilizing certain exterior walls of the El Morro Fort.
