“…26 819 cases of scorpion stings were registered in 2019 by the Poison Control and Pharmacovigilance Center of Morocco. 4 The Androctonus mauretanicus (Am) and Buthus occitanus (Bo), belonging to the Buthidae family, are responsible for the majority of envenoming accidents. 5,6,7 Scorpions are endowed with a venom apparatus that produces venom intended to attack, immobilize prey and defend against predators.…”

Induced pathophysiological alterations by the venoms of the most dangerous Moroccan scorpions Androctonus mauretanicus and Buthus occitanus: A comparative pathophysiological and toxic-symptoms study

Scorpion envenomation is a serious public health issue. Androctonus mauretanicus ( Am) and Buthus occitanus ( Bo) are the most dangerous scorpions in Morocco. Despite their medical relevance, no study has yet related their kinetics of symptom apparition and the consequent tissue disorders at the same interval post-injection. This work achieved the first comparative pathophysiological and toxic-symptoms study between the Am and Bo venoms from a biochemical, toxicological and physiopathological standpoint. The activity of venoms and their subletal dose were determined by administration of increasing concentrations of the venoms. 30, 60 and 120 min following the experimental envenomation in mice, the profile of clinical symptoms was underlined and the main organs: brain, heart, lungs, liver and kidneys were removed for histological examination. The Am venom is a rich source of proteins and three-times more toxic than the Bo. The most observed clinical symptoms are neurological and cardiopulmonary. The Am venom caused histopathological alterations at 30, 60, and 120 min which were more important than the Bo. This study highlighted that both venoms exhibited a strong toxicity with variable intensities. Moreover, we showed the presence of correlation between the level of histopathological disorders observed and the intensity of signs appeared at the same time following venom inoculation.

“…[ 29 ] in his review on scorpion envenomation in Morocco had reported that the three regions with high envenomation incidence are orderly MTH, SMD, and CO. Furthermore, epidemiological study conducted in MTH and SMD had reported that scorpion envenomation is an important health problem in those two regions with a high incidence and lethality rate [ 30 ].…”

Aim:The objective of this study was to establish environmental factors related to scorpion species occurrence and their current potential geographic distributions in Morocco, to produce a current envenomation risk map and also to assess the human population at risk of envenomation.Materials and Methods:In this study, 71 georeferenced points for all scorpion species and nine environmental indicators were used to generate species distribution models in Maxent (maximum entropy modeling of species geographic distributions) version 3.3.3k. The models were evaluated by the area under the curve (AUC), using the omission error and the binomial probability. With the data generated by Maxent, distribution and envenomation risk maps were produced using the “ESRI® ArcGIS 10.2.2 for Desktop” software.Results:The models had high predictive success (AUC >0.95±0.025). Altitude, slope and five bioclimatic attributes were found to play a significant role in determining Androctonus scorpion species distribution. Ecological niche models (ENMs) showed high concordance with the known distribution of the species. Produced risk map identified broad risk areas for Androctonus scorpion envenomation, extending along Marrakech-Tensift-Al Haouz, Souss-Massa-Draa, and some areas of Doukkala-Abda and Oriental regions.Conclusion:Considering these findings ENMs could be useful to afford important information on distributions of medically important scorpion species as well as producing scorpion envenomation risk maps.

“…This increase is a health threat in this area, since with the increase of temperature and decrease of humidity, the prevalence of scorpionism increased. In Hormozgan Province, South of Iran (18), Morocco (19), and Brazil (20) scorpionism also increased. More than 70% of the cases occurred in June, July, and August.…”

The Impact of Climatic Factors on Spatial Distribution of Scorpion Stings in Ardabil Province, North-West of Iran; 2012 - 2017

Background: Scorpion sting is a major health threatening problem in the world, while most victims in Iran are children. Identification of high-risk areas for scorpion stings and dispersal areas map can help to control, prevent, and take effective measures in a timely manner. Objectives: The current study aimed at investigating the scorpion stings and determining the distribution status and spatial analysis in Ardabil Province, NorthWest of Iran. Methods: The current cross sectional study collected the routine human scorpion stings information from health houses, healthcare centers, and hospitals of Ardabil Province from 2012 to 2017 in standard epidemiological surveillance forms. The current study employed Arc GIS 10.2.3 and the space map projection to provide spatial distribution maps of high-risk areas for scorpion stings. Results: Eight hundred fifteen cases of scorpion stings from all 10 counties of Ardabil Province were reported. During the study period, there was direct significant relationship between the increase of scorpion sting cases and temperature, as with 3°C average annual temperature increase, the incidence rate of scorpion sting increased from 5.45/100,000 in 2012 to 16.32/100,000 in 2017. Two hot zones of scorpion stings were detected in Khalkhal and Germi counties; the Southern and Northern areas of the province, respectively. Conclusions: According to the current study findings, there were some hot zones of scorpion stings in Southern and Northern areas of the province. In addition, since the increase of temperature and reduction of rainfall and humidity coincide with the increase of scorpion stings, it is expected that with the increase of temperature in the next years with regard to the global warming phenomenon, scorpion stings also increase in this province.
