Background: Purpureocillium lilacinum eye infections (previously called Paecilomyces lilacinus) make up a significant percentage of the recorded cases of infection by this fungus, and is considered as an emerging pathogen.
Aims: To report a case of ocular mycosis in a patient aged 70, with a double corneal transplantation in the right eye, and exhibiting a poor response to antifungal and surgical treatment.
Methods: Corneal ring and ocular tissues obtained by surgical procedures were cultured in common mycological media. Molecular identification of the isolated fungus was obtained.
Results: Colonies of a filamentous fungus were obtained, and according to the macroscopic and microscopic morphology it was identified as P. lilacinum. The identification was confirmed by molecular methods in a reference laboratory.
Conclusions: Eye infections due to P. lilacinum are rare but serious diseases that requires rapid diagnostic and therapeutic measures to enable visual function to recover.

This study investigates the nematicidal efficacy of strain (AUMC 10620) combined with avermectin (B1a and B1b) against the citrus nematode , both in vitro and in vivo. Laboratory experiments tested four concentrations of (2.5, 5, 10, and 15 × 10 spores/mL) mixed with 250 ppm avermectin, assessing their effects on nematode juveniles (J2) and eggs.

Multiple studies have been conducted to investigate the impact of space conditions on human, plant, and microbial life. This research investigated the virulence of spaceflight mutants of the entomopathogenic fungus Purpureocillium lilacinum (HP7, HP36, HP52) and its original strain (SP535) against Tetranychus cinnabarinus as well as examination of the T. cinnabarinus immune response, including alterations in enzyme profiles and microbiome composition post fungal application.

Background: Malaria remains a critical disease. Leucinostatins from the fungus Purpureocillium lilacinum inhibited the transmission of Plasmodium falciparum to mosquitoes via contact.
Methods: Here, we modified the leucinostatin B (LB) C-terminus to make derivatives and examined their inhibition against malaria transmission to mosquitoes.

Cytospora chrysosperma is the primary pathogen responsible for walnut rot disease, affecting a wide variety of hosts. Currently, chemical agents, particularly agricultural Fungicides, are commonly utilized for the prevention and management of walnut rot. However, this practice has led to the development of drug-resistant pathogens, complicating disease control efforts.
