EARLIELLA SCABROSA PDF

Full size image The isolates were identified by sequencing the ITS region as previously described [ 3 ]. Discussion and conclusion Most acute post-cataract endophthalmitis cases reported worldwide are caused by bacterial infections [ 4 , 5 ]. The patient was then suspected to suffer from acute endophthalmitis induced by bacterial infection. Therefore, empirical treatment consisting of a vitrectomy followed by intraocular irrigation with vancomycin was administered. However, Earliella scabrosa, a type of fungus, was isolated from the vitreous fluid and identified by sequencing the ITS region. In retrospect, this case is not the only acute endophthalmitis case associated with fungi.

Distribution and Host Range This fungus is mainly found in the tropical region and associated with broadleaved trees such as Acacia spp. It is also found associated with surface of pruning wounds on branches and damaged areas on the tree trunks. Signs and Symptoms As wounds serve as entry courts for this fungus, fruiting bodies could be observed on pruning wounds and damaged tissues on branches and tree trunks.

This fungus is likely to cause localised decay on tree. Most often trees observed with this fungus are already weakened with non-specific symptoms of crown abnormality such as defoliation, dieback and small leave size, etc. Pathology This fungus is reported as a saprotrophic fungus on deadwood and causing white rot decay, but its ability to associate with exposed living tissues sapwood on the main trunk of weakened tree hosts reveals the weakly pathogenic nature of this fungus with low virulence.

Further to the degradation by this fungus, the infected trees may be subject to attack by other opportunistic fungal pathogens. Management and Control Risk category: Low YELLOW Since this fungus may aggravate the health and structural stability of weakened trees, infected trees should be put under monitoring if the fungus is associated with the main trunk and major branches of stressed trees.

For trees observed with this fungus on small branches, the defective part should be removed. Fruiting bodies observed on trees should be removed to minimise building-up of fungal inoculum. Fungicides may be applied on the trees as an interim measure to retard fungal growth. As there are occasions where trees detected with Earliella scabrosa are also infected with some other pathogenic root rotting fungi such as Phellinus noxius and Ganoderma spp.
