Selulitis orbital merupakan jangkitan tisu di sekitar mata di dalam ruangan orbit yang
termasuk saraf mata. Ia boleh menyebabkan komplikasi yang membawa kematian
sekiranya merebak melalui saraf mata dan ke otak. Penyebab utama jangkitan
adalah termasuk perebakan jangkitan sinusitis dari ruangan paranasal atau melalui
selulitis preseptal. Kes ini menggambarkan jangkitan di luar kebiasaan mengenai
jangkitan orbital selulitis yang berlaku akibat luka torehan pada konjunktiva mata
yang disebabkan oleh kemalangan. Rawatan antibiotik sistemik yang agresif
mengurangkan risiko komplikasi penglihatan. Kesemua luka pada atau sekelililng
mata haruslah dirawat dengan sebaiknya bagi mengelakkan berlakunya komplikasi
yang membahayakan.
Setosphaeria rostrata, a common plant pathogen causing leaf spot disease, affects a wide range of plant species, mainly grasses. Fungi were isolated from brown spots on rice leaves throughout Peninsular Malaysia, and 45 isolates were identified as Setosphaeria rostrata The isolates were then characterized using morphological and molecular approaches. The mating type was determined using PCR amplification of the mating type alleles, and isolates of opposite mating types were crossed to examine sexual reproduction. Based on nuclear ribosomal DNA ITS1-5.8S-ITS2 region (ITS) and beta-tubulin (BT2) sequences, two phylogenetic trees were constructed using the maximum likelihood method; S. rostrata was clustered in one well-supported clade. Pathogenicity tests showed that S. rostrata isolates are pathogenic, suggesting that it is the cause of the symptoms. Mating-type analyses indicated that three isolates carried the MAT1-1 allele, and the other 42 isolates carried MAT1-2 After isolates with opposite mating types were crossed on Sach's medium and incubated for 3 wk, six crosses produced pseudothecia that contained eight mature ascospores, and 12 other crosses produced numerous pseudothecia with no ascospores. To our knowledge, this is the first report on S. rostrata isolated from leaf spots on rice.
