Four cases of human keratitis caused by the tropical fungus Lasiodiplodia theobromae have been encountered in Miami, Florida bringing to 8 the number of cases reported in the world literature. Two of the ulcers were mild. Three patients recovered without severe impairment of vision after topical polyene treatment, but 1 patient with a severe ulcer required therapeutic keratoplasty after 11 days of topical natamycin. Histopathology revealed fungus deep in the cornea, invading Descemet's membrane. L. theobromae appeared to have collagenase activity in vitro. Inoculation of L. theobromae into the corneas of rabbits produced progressive ulcers. The fungus was endemic in Miami on home grown and imported bananas. Polyene antimycotic antibiotics were fungicidal for L. theobromae in vitro. Thiabendazole was effectively fungistatic but varied in fungicidal effect. Clotrimazole and miconazole were only incompletely fungistatic. Of 7 strains of L. theobromae tested, 4 were relatively resistant to 5-flurocytosine.

Lasiodiplodia theobromae is an emerging threat and the main pathogenic fungi associated with basal stem rot of passion fruit in Guangxi Zhuang Autonomous Region, China. Current pathogen identification protocols are labor-intensive and time-consuming, emphasizing the need for more efficient methods to enable precise surveillance of L. theobromae for early detection and warning.

The commercial production of passion fruit is geographically limited (California, Florida, and Hawaii), but the development of cold-tolerant varieties could expand it beyond warm-climate states (Stafne et.al. 2023).

, a genus in the family Botryosphaeriaceae, has a broad host range and causes dieback, root rot, fruit rot, leaf rot, and blights in many plant species across sub-tropical and tropical geographical areas (Alves et al., 2008). In palms, this fungal pathogen is known to cause fruit and heart rot, wood decay and leaf blight around the globe (Atallah et al.

Background/objectives: Microorganisms such as bacteria, viruses, and fungi are frequently the cause of infections. Antimicrobial agents, such as antibiotics, antivirals, and antifungals, are used to target and eliminate these infectious agents. On the other hand, inflammation is a natural response of the immune system to injury, infection, or irritation.
