Some of the world's most dangerous spiders have been certified in some areas of Iran.
Spider bites are common in some geographical areas, and are sporadic in some regions.
Spider bites can be classified as
latrodectism or
loxoscelism. If the patient had not seen the spider, the clinical manifestations of
latrodectism could be easily mistaken for other types of
bite or
sting; or an
infectious disease, and
withdrawal symptoms, and also
loxoscelism could be mistaken for
cellulitis, various types of skin
infection, or even a
sting from a Gadim scorpion (Hemiscorpius lepturus). Given the nonspecific presentation of
spider bites, one must keep the diagnosis in mind, and question patients, regarding possible exposure to spiders. Physicians recommend becoming familiar with the geographical distribution of Iranian dangerous spiders, clinical manifestations, and management of their
bites. The most useful treatment for
spider bite is
anti-venom administration. Producing
spider bite anti-venom in the Razi
Vaccine and Serum Research Institute is under investigation.
