Brucellosis is one of the most common zoonotic diseases worldwide. It can cause acute febrile illness in human and is a major health problem. Studies in human brucellosis in Malaysia is limited and so far no genotyping studies has been done on Brucella isolates. The aim of the study was to determine the genetic diversity among Brucella species isolated from human brucellosis, obtained over a 6-year period (2009-2014).
Brucellosis is the most common bacterial zoonotic infection. This pathogen may survive and sustain in host. The aim of this study is to define relationship between long noncoding (lnc) RNA-IFNG-AS1 and interferon gamma (IFN-γ) in different groups of patients with brucellosis compared to control group. In this study, associations of lncRNA IFNG-AS1 expression with secretion of IFN-γ level in Sixty patients with brucellosis, which were divided into 3 groups (acute, chronic and relapse groups), as a case group were compared with 20 subjects with negative serological tests and brucellosis clinical manifestation as a control group. In this regard, RNA were extracted from isolated peripheral blood mononuclear cells (PBMCs). LncRNA IFNG-AS1, T-box transcription factor (T-bet) and IFN-γ expressions were detected using quantitative polymerase chain reaction (qPCR). Serum level IFN-γ was assessed using enzyme linked immunosorbent assay (ELISA). The results showed that expression level of LncRNA IFNG-AS1, T-bet and IFN-γ increased significantly in all patient groups in compared to healthy subjects (P
