PROTEIN ELECTROPHORESIS AND REFERENCE INTERVALS OF SERUM PROTEINS OF A CAPTIVE POPULATION OF ROTI ISLAND SNAKE-NECKED TURTLES ().

Protein electrophoresis (PEP) is an important tool in mammals to characterize specific dysproteinemias and detect acute and chronic inflammatory responses. In reptiles, PEP is the gold standard method for globulin fraction determination and albumin measurement. In this study, preliminary reference intervals were established for serum PEP in 22 clinically healthy adult Roti Island snake-necked turtles (), a critically endangered species, kept in captivity and sampled over two monsoon seasons.

Enterococcus casseliflavus infection in a captive Southern Cassowary (Casuarius casuarius): clinical and post-mortem findings.

An adult 22-year-old, male southern cassowary (Casuarius casuarius) presented for lethargy, dysorexia and soft feces. Clinical findings under chemical immobilization were unremarkable except for heterophilic toxic changes on blood smear, reduced albumin/globulin ratio and potentially elevated liver parameters. The animal was treated for suspected hepatobiliary insufficiency and received supportive treatment with daily subcutaneous fluids and medication and was monitored with a quality-of-life assessment.

Fatal Chryseobacterium indologenes infection in a captive red-shanked Douc langur (Pygathrix nemaeus).

We report a case of fatal Chryseobacterium indologenes infection in a captive juvenile red-shanked Douc langur in Singapore Zoo. The animal was treated for suspected melioidosis but died within 48 h. Chryseobacterium indolegenes was isolated from the liver and should be included as a differential for bacterial infections in the tropics.

Management of Entamoeba histolytica in the non-human primates at the Singapore Zoo.

Amebic dysentery caused by Entamoeba histolytica accounts for significant morbidity in the non-human primates (NHP) at the Singapore Zoo. This includes the animals in the collection as well as a sizeable free-roaming wild crab-eating macaque (Macaca fascicularis) population. The disease is of great concern because of its zoonotic potential.

Treatments and outcomes of severe hemorrhagic enteritis in three eastern bongos (Tragelpahus eurycerus isaacii) at the Singapore Zoo.

Three eastern bongos (Tragelaphus eurycerus isaaci) presented acutely with hemorrhagic diarrhea at the Singapore Zoo, thought to be caused by a mouldy batch of hay. Repeated fecal tests were negative of parasites and common gastrointestinal bacteria including salmonella and campylobacter. The diarrhea resolved for all individuals after a week of leaf-only diet.

Fatal Septicemia and Mastitis in Wild Sunda Colugos (Sunda Flying Lemurs; ) in Singapore.

Two free-ranging female Sunda colugos (Sunda flying lemur; ) were found dead in Singapore in November 2018 and February 2019. Septicemia and mastitis were diagnosed in both animals on postmortem examination. Infectious diseases have not previously been established as a cause of death in wild Sunda colugos.

Canine Parvovirus-2c (CPV-2c) Infection in Wild Asian Palm Civets () in Singapore.

We report pathogenic feline parvovirus and canine parvovirus-2c infection in wild Asian palm civets (), as demonstrated by histopathology and immunohistochemistry findings of parvoviral enteropathy. We performed molecular characterization and phylogeny studies to obtain an improved understanding of disease transmission dynamics between domestic and wild carnivores.

Characterization of Fowlpox virus in chickens and bird-biting mosquitoes: a molecular approach to investigating Avipoxvirus transmission.

Avian pox is a highly contagious avian disease, yet relatively little is known about the epidemiology and transmission of Avipoxviruses. Using a molecular approach, we report evidence for a potential link between birds and field-caught mosquitoes in the transmission of Fowlpox virus (FWPV) in Singapore. Comparison of fpv167 (P4b), fpv126 (VLTF-1), fpv175-176 (A11R-A12L) and fpv140 (H3L) gene sequences revealed close relatedness between FWPV strains obtained from cutaneous lesions of a chicken and four pools of Culex pseudovishnui, Culex spp.
