Africanized Honey Bee Sting-Induced Stress-Related Cardiomyopathy: A Bee or Octopus Trap.

Cureus 2021 Jul 28;13(7):e16681. Epub 2021 Jul 28.

Cardiology, Eric Williams Medical Sciences Complex, Champs Fleurs, TTO.

The Africanized honey bee commonly referred to as the "killer bee," is a hybrid of the East African lowland honey bee with various European honey bees. These bees tend to be more hostile as compared to other bee species. Their stings may have devastating clinical sequelae, including cardiovascular, cerebrovascular events, and fatalities. Read More

Diagnosis and Treatment of Lower Motor Neuron Disease in Australian Dogs and Cats.

J Vet Med 2018 6;2018:1018230. Epub 2018 Aug 6.

University of Queensland School of Veterinary Science, Gatton, QLD 4350, Australia.

Diseases presenting with lower motor neuron (LMN) signs are frequently seen in small animal veterinary practice in Australia. In addition to the most common causes of LMN disease seen world-wide, such as idiopathic polyradiculoneuritis and myasthenia gravis, there are several conditions presenting with LMN signs that are peculiar to the continent of Australia. These include snake envenomation by tiger ( spp. Read More

Combined Transcriptomic and Proteomic Analysis of the Posterior Salivary Gland from the Southern Blue-Ringed Octopus and the Southern Sand Octopus.

J Proteome Res 2016 09 5;15(9):3284-97. Epub 2016 Aug 5.

Department of Biochemistry, La Trobe Institute for Molecular Science, La Trobe University , Melbourne, Victoria 3086, Australia.

This study provides comprehensive proteomic profiles from the venom producing posterior salivary glands of octopus (superorder Octopodiformes) species. A combined transcriptomic and proteomic approach was used to identify 1703 proteins from the posterior salivary gland of the southern blue-ringed octopus, Hapalochlaena maculosa and 1300 proteins from the posterior salivary gland of the southern sand octopus, Octopus kaurna. The two proteomes were broadly similar; clustering of proteins into orthogroups revealed 937 that were shared between species. Read More

Marine envenomations.

Emerg Med Clin North Am 2014 Feb;32(1):223-43

Department of Emergency Medicine, Johns Hopkins University, 1830 East Monument Street, Baltimore, MD 21287, USA. Electronic address:

This article describes the epidemiology and presentation of human envenomation from marine organisms. Venom pathophysiology, envenomation presentation, and treatment options are discussed for sea snake, stingray, spiny fish, jellyfish, octopus, cone snail, sea urchin, and sponge envenomation. The authors describe the management of common exposures that cause morbidity as well as the keys to recognition and treatment of life-threatening exposures. Read More

Death in the octopus' garden: fatal blue-lined octopus envenomations of adult green sea turtles.

Mar Biol 2012 3;159(3):689-695. Epub 2011 Dec 3.

Independent Marine Biochemistry Research, Moreton Bay Research Station, P.O. Box 138, Dunwich, QLD 4183 Australia.

The blue-lined octopus contains the powerful neuromuscular blocker tetrodotoxin (TTX), which causes muscle weakness and respiratory failure. is regarded as one of the most venomous marine animals in the world, and multiple human fatalities have been attributed to the octopus. To date, there have been no recorded incidents of an envenomation of a wild animal. Read More

Animal-related fatalities--part II: characteristic autopsy findings and variable causes of death associated with envenomation, poisoning, anaphylaxis, asphyxiation, and sepsis.

J Forensic Sci 2012 Mar 7;57(2):375-80. Epub 2011 Oct 7.

Forensic Science SA, 21 Divett Place, Adelaide, SA 5000, Australia.

In addition to blunt and sharp trauma, animal-related fatalities may result from envenomation, poisoning, anaphylaxis, asphyxiation, and sepsis. Although the majority of envenomation deaths are caused by hornets, bees, and wasps, the mechanism of death is most often anaphylaxis. Envenomation resulting from the injection of a poison or toxin into a victim occurs with snakes, spiders, and scorpions on land. Read More

Encounters with venomous sea-life.

J Emerg Med 2011 Jan 4;40(1):103-12. Epub 2010 Jan 4.

Universidad de Monterrey, Monterrey, Nuevo León, México.

Background: Sea-life with envenomation capabilities are quite abundant and diverse worldwide, being predominantly found in tropical waters. Most envenomations occur not as an attack, but as a result of self defense when the animal perceives danger; and often when locals or tourists are engaged in recreational activities. Most of these cases have only minor injuries, and few are fatal. Read More

Blue-ringed octopus (Hapalochlaena sp.) envenomation of a 4-year-old boy: a case report.

Clin Toxicol (Phila) 2008 Sep;46(8):760-1

Mater Children's Hospital, Paediatric Intensive Care, Raymond Terrace, South Brisbane, Brisbane, Australia.

Introduction: The blue-ringed octopus (Hapalochlaena sp.) is a small animal, which can inject a toxin that produces a respiratory arrest within minutes. This envenomation is a rare occurrence with very few reported outcomes in children. Read More

Struan Sutherland--Doyen of envenomation in Australia.

James Tibballs

Toxicon 2006 Dec 15;48(7):860-71. Epub 2006 Jul 15.

Australian Venom Research Unit, Department of Pharmacology, The University of Melbourne, Australia.

Struan Sutherland (1936-2002) was the doyen of medical research in the field of envenomation and the ultimate authority on the medical management of envenomated victims in Australia for almost 3 decades. In 1981 as Head of Immunology Research of Commonwealth Serum Laboratories (CSL), he produced an antivenom against the Sydney Funnel-web Spider (Atrax robustus)-an accomplishment that had defied numerous previous attempts. Struan also invented the pressure-immobilisation technique of first-aid for snake bite. Read More

Respiratory failure and lethal hypotension due to blue-ringed octopus and tetrodotoxin envenomation observed and counteracted in animal models.

J Toxicol Clin Toxicol 1986-1987;24(6):485-502

The effects of crude blue-ringed octopus venom gland extract and tetrodotoxin (TTX) on anaesthetised rats and rabbits were studied. Paralysis of the respiratory musculature causing anoxia and cyanosis was overcome with positive, artificial respiration. The second lethal mechanism of the toxins: rapid and severe hypotension, had to be counteracted peripherally, since neural transmission had been drastically reduced by the toxins. Read More

Survival after severe envenomation by the blue-ringed octopus (Hapalochlaena maculosa).

D G Walker

Med J Aust 1983 Dec 10-24;2(12):663-5

I report two cases of life-endangering respiratory failure after envenomation by a blue-ringed octopus (Hapalochlaena maculosa). Early and efficient support of respiratory function is vital in such cases. Cardiac asystole occurred in one patient. Read More
