RESUMO
Background: Kerman Province is one of the endemic foci of scorpionism in southeastern Iran. Totally 17 species are reported for Kerman Province fauna. The current study seeks to determine the fauna of medically important scorpions in northern parts of this province. Methods: A descriptive cross-sectional study was conducted from January 2019 to March 2021. The specimens were captured from different areas, by rock-rolling during day and using Ultraviolet light at night. The specimens were preserved in ethanol (80%) and then identified using reliable identification keys for scorpions. Results: Totally, 499 specimens were captured from eight cities in northern Kerman. In total, 11 species belonging to three families were identified. Buthacus sp. is reported for the first time from Kerman Province. Buthacus sp., Hottentotta cf. juliae, and Hottentotta cf. schach, were the lowest in frequency of occurrence, against Mesobuthus navidpouri as the highest frequency. Conclusion: The results of this study are useful for the preparation of regional or monovalent antivenom for the Razi Vaccine and Serum Research Institute. Additionally, the obtained data are useful for the effective planning of scorpion control programs in the northern parts of Kerman Province, Iran.
RESUMO
BACKGROUND: Mosquitos due to their role in the transmission of different pathogens to humans are considered as an important group in the phylum Arthropoda. According to the WHO and FAO guideline different groups of insecticide applied for controlling pests in both the agricultural and public health sectors. METHODS: All the data published about resistant status of the mosquitoes Anopheles, Culex, Aedes and Culiseta species were searched on PubMed, Elsevier, Web of Science, Magiran and google scholar. The objectives of this study was to review the trend of resistance to insecticides during 2000-2020 in medically important mosquitoes in Iran. The criteria for resistant are followed according to WHO guideline. RESULTS: The Results showed that there are widespread, multiple resistances in the country to different organochlorine, organophosphates, carbamate and pyrethroids insecticides in the mosquitoes. CONCLUSION: The effect of pesticide residues on the environment could be a cause for selection pressure on mosquitos and lead to insecticides resistance to them. Insecticides resistance is main challenge of the vector control program. Also result will provide a guideline for control of the mosquito-borne diseases in the country as well as the world.
RESUMO
BACKGROUND: Ticks are vectors of a wide variety of pathogens that can be transmitted to humans, and tick-borne diseases are a significant public health issue worldwide. The present study was carried out on the hard tick infestation of livestock transported to Rafsanjan slaughter house in the southeast of Iran. METHODS: A cross-sectional survey was carried out biweekly from April to September 2016 to determine tick infestation of the meat-producing animals. All the livestock included in our study were thoroughly inspected for the presence of hard ticks on different parts of their bodies. RESULTS: A total of 258 hard ticks were collected from the body of livestock hosts. The ticks that were sampled were classified into two genera and five species: Hyalomma marginatum, Hy. anatolicum, Hy. asiaticum, Hy. dromedarii, and Rhipicephalus sanguineus. Hyalomma dromedarii was the most abundant species in the study area. More than 50 percent of the sampled ticks were collected from the body of camels brought to the slaughter house however molecular analysis showed no Crimean Congo Hemorrhagic Fever (CCHF) virus infection in tick specimens. The Sex ratio of the sampled hard ticks shows that female tick infestation was more common among the study livestock. CONCLUSION: Due to the crucial role of hard ticks in the transmission of different pathogens to humans, additional investigations are necessary to determine the risk of consumption of infested meat-producing animals in the study area.
