Acacia longifolia – a small perennial tree from the Fabaceae family, known for its invasiveness due to its high seed production capacity. Originating from Africa and Australia, it is widespread in subtropical regions worldwide, including Australia, Africa, Arab countries, Malaysia, Brazil, the USA, and Spain. The flowering period usually occurs at the end of winter. Exposure to acacia can cause allergic reactions such as rhinitis, conjunctivitis, and asthma in sensitized individuals. Cross-reactivity of acacia pollen has been identified with pollen from other plants, including Salsola kali, Amaranthus retroflexus, Chenopodium album, Kochia scoparia, mesquite, date palm, and ryegrass.
Two allergenic protein molecules with molecular weights of 66 kDa and 85 kDa have been identified in acacia pollen extract. Studies have shown that pollen protease enzymes can damage the respiratory epithelium, promoting sensitization and inflammation. Cross-reactivity of acacia with other pollens has been confirmed with Salsola kali, Amaranthus retroflexus, Chenopodium album, Kochia scoparia, Prosopis juliflora (mesquite), and ryegrass (Lolium perenne). Acacia pollen also shows cross-reactivity with date palm pollen (Phoenix dactylifera L.).
