Background: Loop-mediated isothermal amplification (LAMP) is a method already claimed as a simple technique to amplify DNA/ RNA using four to six primers as “a set” from conserved sequence of target gene. In this study we optimize the use of LAMP for detection of Mycobacterium tuberculosis in clinical isolates from Indonesia.Methods: Procedures to perform LAMP were optimized, then the method was applied to 122 archieved samples of DNA’s Mtb from clinical TB patients with Acid Fast Bacilli (AFB) smears positive. The samples were obtained in 2008 from 13 provinces in Indonesia for genotyping study, which then become collections of Center for Biomedical and Basic Technology of Health (CBBTH), NIHRD Indonesia. The optimization tests include sensitivity and specificity tests of several sets primers, which were evaluated using 10-fold serially diluted DNA of Mtb H37Rv and 12 species of Mycobacteria. Three equipments consisted of LAMP turbidimeter, heating block and water bath were compared for its ability in DNA amplification. Detection of M. tuberculosis from clinical isolates used set primers specific for gyrB gene, amplicon was detected with UV fluorescence system.Results: The results showed that the highest sensitivity was obtained using the set primers specific for 16S rRNA and gyrB which could detect 10.0 fg to 1.0 pg genomic DNA of Mtb H37Rv. The set primers specific for gyrB gene was the most specific primers. Application of LAMP using gyrB set primers on Indonesian clinical isolates showed 94.2% (114/121) positivity rate.Conclusion: LAMP method is potentially used in TB diagnosis in Indonesia.

A placebo double blind pre-post human study was conducted in apparently healthy adults. There were two treatment groups consisting of Group A and B representing probiotic and placebo group, respectively. Twenty four participants were randomly assigned, each supplemented with either placebo or probiotic Lactobacillus plantarum IS-10506. The micro encapsulated powder was given at a dose of 2.6x1010 CFU/day for 21 consecutive days. Stool samples were collected before and after the supplementation. The fresh stool samples were analyzed for the viability of Lactobacillus sp. by conventional plate count method in MRS agar. Some stool samples were kept frozen to be analyzed by using real time PCR to trace back the availability of Lactobacillus plantarum with species specific primer. The Lactobacillus sp. in stools of healthy adults given microencapsulated probiotic Lactobacillus plantarum IS-10506 powder was significantly more than those who consumed microencapsulated placebo powder. Molecular detection by qPCR confirmed the availability of Lactobacillus plantarum in fecal samples of the probiotic group after given the supplementation for 21 days. The molecular detection validation confirmed that probiotic Lactobacillus plantarum was available in the fecal samples of the probiotic group of healthy adults. However, the availability and viability of Lactobacillus plantarum were not consistently found in the intestinal tract.

Virus and bacteria are microbes which are very common cause human infection. Most of the bacterial infection can be eradicated by antibiotics and infection symptoms disappear. But for virus infection, once infected, the virus will persistently stay in the host, even undergo not only a lytic cycle but also integrated into host genome. Nowadays, at least 6 virus type are consistently related to human cancer, such as EBV,HPV,HTLV,HBV,HCV,HKSV, and the new one Merkel Virus (MCV). Although not every infected people will get cancer, but around 20% of the whole cancer in human are caused by viral oncogene.Class one oncogenic bacterial is Helicobacter pylori. Infection with this bacteria can cause persistent gastro duodenal inflammation which cause some alteration in gastric cell growth into transformation. Expression of Cag gene and Vac gene and some expression of OMP protein usually link to gastric cancer.Molecular mechanisms of carcinogenesis for every virus which cause infection is a very complex , which include several processes caused by cell transformation. Besides, other host and environmental factors are also play a significant role in cancer development. Some scientist put a Hallmark analysis as a model to quickly summarize what pathobiology process will happen and what gene or protein caused the process. The Hallmark analysis comprise of several process which may happen simultaneously because some of the Hallmark is caused by the same protein. The Hallmark consists of various virus strategies in oncogenesis such as promoting angiogenesis, avoiding immune destruction, genome instability and mutation, deregulating cellular energetic, resisting cell death, sustaining proliferative signaling, evading growth suppressors, enabling cellular immortality, promoting inflammation and activation metastasis. For example, infection by HPV, will cause low grade dysplasia which can continue to invasive cervical cancer. After host cell transformation, in the long control region genes, E6 and E7 protein will cause several strategies in oncogenesis including resisting cell death and evading growth suppressors. HBV infection will end without any serious liver damage, but after cell transformation, almost all Hallmark strategies of viral oncogenesis are happening step by step in line with the severity of liver cell damage.As the onset of cancer development after infection can last years, there are an opportunity to design either vaccine or genetic therapy to minimalize further risk of cancer in human

Diagnosis of Neisseria gonorrhoeae infection is needed for patient therapy and for reducing this bacterial transmission in the population. The culture method is a gold standard method for N. gonorrhoeae detection, however it has low sensitivity. Among molecular methods with high sensitivity and specificity, SYBR Green real-time PCR is the potential method for N. gonorrhoeae detection. In this study, we developed an SYBR Green real-time PCR-based system assay for N. gonorrhoeae detection. Several PCR conditions were optimized and analyzed including primer annealing temperature, DNA template volume, the limit of detection (LoD), cross-reaction with others (bacteria, viruses, fungus, protozoa), and quality assurance. The results showed that the annealing temperature and DNA template volume were 60oC and 5 µL, respectively. The LoD was 29 DNA copies corresponding to 3 bacterial cells per reaction. No cross-reaction was detected for other bacteria, viruses, fungus and protozoa. The external quality assurances enrolled in 2019 and 2021 showed 100% concordance. The preliminary testing for clinical samples was also 100% concordance. In conclusion, the SYBR Green real-time PCR-based system assay developed in this study is promising for application in clinical laboratories.

Publisher : Indonesian Society for microbiology

Burn injury causes mechanical disruption to the skin, which allows environmental microbes to invade the deeper tissues. A prospective study of infections in burn patients has shown that the incidence of hospital acquired bacterial infection in burn wounds was high. In the Burns Unit, Cipto Mangunkusumo Hospital, Jakarta, 94 patients were hospitalized from January to July 2004. The objective of this study was to evaluate the hospital acquired infections in burn wounds. Using a cross sectional study, 49 patients were included. The specimens for bacterial investigation were obtained from clean eschar which has healthy tissue taken at day 1, day 5 and day 10. At the same time, bacterial investigations were conducted from the air and the water, as well as from the hand and nasal swabs of hospital personnel. The results show that Klebsiella pneumoniae is the most prominent bacterium found in the wounds, but it is also found in the air. Pseudomonas aeruginosa was the number two causative bacteria which caused a change of the bacterial infectivity on day 5 and 10. These bacteria were always found when we conducted bacterial investigations from the water resource of the burns unit. Methicillin Resistant Staphylococcus aureus is also found in the nasal swab of hospital personnel. Using the antibiogram pattern, there were similarities between bacteria found in the wounds and in bacteria found in the air and water. In conclusion, hospital acquired burn wound infection in Burns Unit, Cipto Mangunkusumo Hospital is as high as 62%. The surveillance data are very important for developing good clinical practice guidelines in burn injury treatment and management
