In 2020, a shocking and tragic event occurred in Africa that puzzled both scientists and conservationists. Hundreds of African elephants in Botswana and Zimbabwe mysteriously dropped dead. This article delves into the perplexing cause behind these deaths and the potential implications for these magnificent creatures.

Introduction

A catastrophic event unfolded in May and June 2020 when approximately 350 elephants in Botswana mysteriously died. Adding to the distress, another 35 elephants perished between August and September 2020 in Northwestern Zimbabwe. The initial shock came from the fact that their carcasses were found intact, ruling out poaching for tusks or meat. Additionally, there was no evidence of poisoning, typically associated with human-animal conflict. This baffling situation left experts searching for answers.

The Mysterious Elephant Deaths

Wildlife experts initially speculated that cyanobacteria, commonly known as blue-green algae, might be the cause of these elephant deaths. Cyanobacteria produce deadly toxins when they bloom, posing a threat to wildlife. However, further investigation ruled out this theory, leaving the mystery unsolved.

Suspected Causes

In a new study, scientists from the UK conducted research on 15 of the affected elephants from the August to September 2020 event. To their surprise, six of these elephants were found to be infected with a bacterium called Bisgaard taxon 45, which led to fatal septicemia, a severe and often deadly blood poisoning. This discovery raised significant questions about the role of this bacterium in the larger context of the elephant deaths.

The Discovery: Bisgaard taxon 45

Bisgaard taxon 45 is a member of the Pasteurellaceae bacterial family, but little is known about its characteristics and effects. What makes this discovery particularly intriguing is that it had never been observed in wild elephants before. The source of infection and the method of transmission remain mysteries, creating a complex puzzle for researchers to unravel.

This bacterium has been previously reported in healthy parrots, leading scientists to consider the possibility that it represents an unknown part of elephants' normal flora in this region. Alternatively, elephants could have contracted the bacterium from another animal they share their environment with. Their social nature and frequent physical contact make it possible for the infection to spread among these magnificent creatures. Furthermore, the elephants' natural curiosity about death, where they investigate deceased family members, may have exposed them to the bacterium.

Professor Falko Steinbach, head of virology at the UK Animal and Plant Health Agency, emphasizes the potential transmission of the bacterium due to the sociable nature of elephants and the stress linked to extreme weather events, such as drought, which can make outbreaks more likely.

Implications for Elephant Populations

The consequences of this discovery are substantial. The African forest elephant (Loxodonta cyclotis) is now listed as Critically Endangered, and the African savanna elephant (Loxodonta africana) as Endangered, according to the IUCN Red List. This little-known pathogen in elephants could add to the already mounting pressures on their existence.

Professor Steinbach underscores the need for further research to understand the bacterium and its long-term implications for African elephant populations and other wildlife. This discovery has profound implications for the conservation efforts aimed at preserving these majestic creatures.

Conclusion

The mystery of the mass elephant deaths in 2020 appears to have a potential lead with the discovery of Bisgaard taxon 45. While this bacterium remains largely enigmatic, its presence in infected elephants raises critical questions about the health and safety of these animals. The need for continued research and conservation efforts is paramount.
