In 2014, a total of 16 riverterrapins (Batagur affinis), locally calledtuntung sungai, died due to variouscauses and a post mortem was carriedout. Complete diagnostic evaluationof parasitological and bacteriologicalfindings were recorded. Significantparasitological findings consisted of seventerrapins showing presence of Ascarid(Sulcascaris sulcata) and Strongyle(Oesophagostomum sp.) worms in the gutcontents. Strongyle and strongyloides eggswere detected using McMaster’s method onfaeces of 12 terrapins. Bacterial culturesfrom organs indicated the presence ofE. Coli, Staphylococcus epidermidis,Staphylococcus chromogenes, Aeromonashydrophila (4+) dan E.Coli (4+). Thisindicates that common parasites andbacteria are important in the conservationprogrammes for river terrapins andmeasures to curb the infection is highlyrecommended. Continuous data collectionwill enable its management and assessmentin control programmes for a more effectiveconservation programmes.

The major causes of the decline of the Dugong population along the urban coast of Mersing, Johor includes gill netting, subsistence hunting, habitat loss from extreme weather events that are likely to be exacerbated by climate change, humansettlement, breach of the bots and sea water pollution. In March 2017, a male Dugong dugon, estimated age of 10 to 20 years, wasincidentally found dead near Pulau Tinggi, Mersing, Johor by a fisherman. The entire body was found to have old and new scarsat the anterior part of the abdomen. The right eye was protruded out and bleeding which indicated that the eye was piercedby a sharp object. Necropsy revealed the upper small intestine and the stomach compartments were semi-impacted with a massive helminth burden (more than 1,000 nematodes). Paradujardinia halicoris worms were identified based on morphological characteristics. Zoonotic fungus named Madurella mycetomi were isolated from heart and lung after incubation for 14 days.Histologically, the lung was confirmed to have the presence of big mast cells which formed capsules, indicating presence offungal spores causing systemic mycoses where the macrophages invade and engulf the spores. The shrinkage of myocardium myocyte and myocardium necrosis with mild vasculitis indicates heart failure. Groucott’s stain confirmed Madurella mycetomi infection that induced systemic pulmonary and myocardium mycosis in Dugong dugon.

A detailed post mortem was carried out on a male Bryde’s whale
Balaenoptera brydei, a cetacean of suborder Mysticetes, with a wide geographical distribution. The stranded whale, weighing approximately 3.5 metric tons was found beached along the Pekan Nenasi River, Pahang in East Coast of Malaysia facing South China Sea. Gross pathology showed severe hemorrhagic gastritis, probably
due to foreign material found compacted in the multichamber stomach, severe congestion in the various vital organs due to toxemia, and severe endoparasite burden in the intestine. Thousands of Digeneans
were found in both the caecum and colon. Morphological identification was carried out on these parasites which were identified as Ogmogaster species. As co parasites, the acathocephalan worms Falsifilicollis species was also detected in the large intestine. Histological examination indicated severe bronchointerstitial embolic pneumonia, chronic interstitial
hemorrhages, intra alveolar septa thickening in lung tissue; chronic hepatic interstitial hemorrhage, hepatocellular and centrilobular degeneration on the liver tissue; renal tubular and glomerular
necrosis in kidney tissue; splenic necrosis and hemorrhages; intestinal mucosal layer necrosis and severe intestinal villi necrosis. The continuing survival of Bryde’s species whale is precarious, because of disregard for appropriate measures for their
conservation and to conduct appropriate study for the cause of death.
