Monkeys overharvest shellfish

Resource depletion through primate stone technology

Tool use has allowed humans to become one of the most successful species. However, tool-assisted foraging has also pushed many of our prey species to extinction or endangerment, a technology-driven process thought to be uniquely human. Here, we demonstrate that tool-assisted foraging on shellfish by long-tailed macaques (Macaca fascicularis) in Khao Sam Roi Yot National Park, Thailand, reduces ...

Adjuvanticity of pGPL-Mc and LRS in the Immune Responses of Monkeys to Oral Immunization with Diphteria and Tetanus Toxoids

Alimentary tract parasites of vervet monkeys (Cercopithecus aethiops): A potential reservoir for human transmission

Monkeys are important experimental models for investigating human diseases. The aim of this study was to survey the alimentary tract parasites among imported vervet monkeys (Cercopithecus aethiops) to Iran. Fecal samples were collected from 40 vervets imported from Tanzania to Razi Vaccine and Serum Research Institute of Iran. Fecal samples were assessed by direct smear and Telman sedimentation...

Characterization of a strain of infectious hepatitis E virus isolated from sewage in an area where hepatitis E is not endemic.

Raw sewage samples from an area where hepatitis E is not endemic (Barcelona, Spain) were analyzed by reverse transcriptase-PCR followed by nested PCR. One of the 37 tested samples showed a positive result for hepatitis E virus (HEV). The detected strain was amplified by inoculation into rhesus monkeys, and the course of the infection was studied by analyzing serological and biochemical paramete...

Shellfish Poisoning and Toxins

Shellfish toxins are the most dangerous marine biotoxins, and produced by free living micro-algae. Shellfish toxins are concentrated in flesh, and poisoning occurs when these contaminated shellfish is consumed. They can cause paralytic shellfish poisoning (PSP), diarrhetic shellfish poisoning (DSP), neurotoxic shellfish poisoning (NSP), amnesic shellfish poisoning (ASP) and azaspiracid shellfis...
