“…Paederus fuscipes Curtis is a widespread beetle, with a distribution from the British Isles in the east, across Central Asia to Japan, and southeast to Australia. Although P. fuscipes preys on several agricultural pests and represents an important beneficial insect [27], it can also adversely affect human health, because its vesicant hemolymph can cause dermatitis linearis and conjunctivitis if it comes into contact with human skin [28][29][30]. P. fuscipes neither bite nor sting, but can cause dermatitis linearis and conjunctivitis by accidental brushing or crushing of the insects over an exposed area of the human skin.…”

The maternally inherited obligate intracellular bacteria Wolbachia infects the reproductive tissues of a wide range of arthropods and affects host reproduction. Wolbachia is a credible biocontrol agent for reducing the impact of diseases associated with arthropod vectors. Paederus fuscipes is a small staphylinid beetle that causes dermatitis linearis and conjunctivitis in humans when they come into contact with skin. Wolbachia occur in this beetle, but their relatedness to other Wolbachia, their infection dynamics, and their potential host effects remain unknown. In this study, we report the phylogenetic position and density dynamics of Wolbachia in P. fuscipes. The phylogeny of Wolbachia based on an analysis of MLST genotyping showed that the bacteria from P. fuscipes belong to supergroup B. Quantitative PCR indicated that the infection density in adults was higher than in any other life stage (egg, larva or pupa), and that reproductive tissue in adults had the highest infection densities, with similar densities in the sexes. These findings provide a starting point for understanding the Wolbachia infection dynamics in P. fuscipes, and interactions with other components of the microbiota.

“…The patient initially presented with severe blepharitis in the left eye. A previous report has demonstrated the efficacy of wound dressing material containing silver sulfadiazine in managing Paederus -associated dermatitis [ 15 ]. Topical antibiotics and a combination ointment with a steroid and antibiotic were prescribed, resulting in resolution of the blepharitis within 2 weeks and improvement in the keratitis.…”

Toxicity of Paederus species to eyes has scarcely been reported. This report presents a case of chemical blepharokeratoconjunctivitis with delayed re-epithelialization caused by Paederus fuscipes in a patient with dry eye after laser-assisted in situ keratomileusis (LASIK). A 47-year-old woman who had undergone LASIK for myopia 10 years prior experienced visual disturbance and pain in her left eye after being hit by a P. fuscipes insect in her eye 1 day prior to evaluation. At the initial presentation, dermatitis around the patient’s left eye, eyelid oedema, conjunctival chemosis, corneal epithelial defects, and a best corrected visual acuity (BCVA) of 20/200 were noted. No gram-positive/negative bacteria or indication of cellulitis/elevated inflammation was detected. Administration of topical steroids (betamethasone) and antibiotics (topical: cefmenoxime and levofloxacin; intravenous: ceftriaxone) improved the non-infectious chemical blepharokeratoconjunctivitis; however, the large corneal epithelial defect remained for 10 days. Switching from betamethasone to a preservative-free form facilitated re-epithelialization, and the patient’s BCVA improved to 20/16 after 2 months. Ophthalmologists should consider the toxicity of the Paederus species on the ocular surface and eyelid.
