Article Synopsis
  • Neoscytalidium dimidiatum and Bipolaris species are plant-pathogenic fungi that can also cause human diseases, as found in recent patient samples.
  • The genome of N. dimidiatum was sequenced and compared to B. papendorfii, revealing important genetic similarities related to their ability to infect a wide range of hosts.
  • The study highlights key genes involved in melanin production, nutrient uptake, and the breakdown of plant materials, as well as factors contributing to their pathogenicity in skin and nail infections, which sets the stage for future research on their survival and infection mechanisms.

The polyhydroxyalkanoate (PHA) producing capability of four bacterial strains isolated from Antarctica was reported in a previous study. This study analyzed the PHA synthase genes and the PHA-associated gene clusters from the two antarctic Pseudomonas isolates (UMAB-08 and UMAB-40) and the two antarctic Janthinobacterium isolates (UMAB-56 and UMAB-60) through whole-genome sequence analysis. The Pseudomonas isolates were found to carry PHA synthase genes which fall into two different PHA gene clusters, namely Class I and Class II, which are involved in the biosynthesis of short-chain-length-PHA (SCL-PHA) and medium-chain-length-PHA (MCL-PHA), respectively.

Article Synopsis
  • The study focuses on the causes of pneumonic pasteurellosis and hemorrhagic septicemia (HS) in large ruminants.
  • Researchers sequenced the complete genome of strain PMTB2.1, a specific strain responsible for the disease.
  • The strain was isolated from buffaloes that died from septicemia, highlighting its impact on animal health.

Introduction: Currently available tests have limitations for the identification of Brucella species and strains, and their genetic lineage. The genome sequence of the rpoB gene encoding the β-subunit of DNA-dependent RNA polymerase was investigated for its use in genotyping Brucella melitensis.

Methodology: Complete rpoB gene sequences of globally distributed Brucella melitensis strains were analyzed.

is a common plant pathogen that causes leaf spot disease in a broad range of crop, and it heavily affect rubber trees in Malaysia (Hsueh, 2011; Nghia et al., 2008). The isolation of UM 591 from a patient's contact lens indicates the pathogenic potential of this dematiaceous fungus in human.

Plant defensins are plant defence peptides that have many different biological activities, including antifungal, antimicrobial, and insecticidal activities. A cDNA (EgDFS) encoding defensin was isolated from Elaeis guineensis. The open reading frame of EgDFS contained 231 nucleotides encoding a 71-amino acid protein with a predicted molecular weight at 8.

Burkholderia cenocepacia infection often leads to fatal cepacia syndrome in cystic fibrosis patients. However, antibiotic therapy rarely results in complete eradication of the pathogen due to its intrinsic resistance to many clinically available antibiotics. Recent attention has turned to the identification of essential genes as the proteins encoded by these genes may serve as potential targets for development of novel antimicrobials.

Cladophialophora bantiana is a dematiaceous fungus with a predilection for causing central nervous system (CNS) infection manifesting as brain abscess in both immunocompetent and immunocompromised patients. In this paper, we report comprehensive genomic analyses of C. bantiana isolated from the brain abscess of an immunocompetent man, the first reported case in Malaysia and Southeast Asia.

Background: Basal stem rot (BSR) is a fungal disease in oil palm (Elaeis guineensis Jacq.) which is caused by hemibiotrophic white rot fungi belonging to the Ganoderma genus. Molecular responses of oil palm to these pathogens are not well known although this information is crucial to strategize effective measures to eradicate BSR.

Article Synopsis
  • Basal stem rot is a significant disease affecting oil palm caused by Ganoderma species, with Trichoderma and mycorrhizae suggested to reduce its severity.
  • Research focused on examining the expression of eleven defense-related genes in oil palm roots infected with Trichoderma harzianum T32 and mycorrhizae over time.
  • Results showed that certain genes (like EgBBI2 and EgDFS) were significantly upregulated in roots treated with mycorrhizae and Trichoderma, indicating their potential role in enhancing the plant's defense mechanisms against the disease.

The outbreak of extensively drug-resistant tuberculosis (XDR-TB) has become an increasing problem in many TB-burdened countries. The underlying drug resistance mechanisms, including the genetic variation favored by selective pressure in the resistant population, are partially understood. Recently, the first case of XDR-TB was reported in Malaysia.

Background: Brucellosis is an important zoonotic disease that affects both humans and animals. We sequenced the full genome and characterised the genetic diversity of two Brucella melitensis isolates from Malaysia and the Philippines. In addition, we performed a comparative whole-genome single nucleotide polymorphism (SNP) analysis of B.

Ochroconis constricta is a soilborne dematiaceous fungus that has never been reported to be associated with human infection. Here we report the first draft genome sequence of strain UM 578, isolated from human skin scraping. The genomic information revealed will contribute to a better understanding of this species.
