Introduction: Lower respiratory tract infections (LRTI) are a substantial threat for children worldwide. Currently, there is a lack of knowledge about the burden and etiology of LRTI in children under five years of age in Indonesia. Methodology: We have systematically searched the available English and Indonesian scientific literature to review and summarize data on LRTI and LRTI-associated invasive disease, and bacterial carriage in the upper respiratory tract in children under five years of age in Indonesia. Results: Overall, data on the burden and etiology of LRTI in children under five years of age in Indonesia is very limited. The data are primarily collected in Java. Data from other parts of Indonesia, including Sumatra, Kalimantan, and Sulawesi, are scarce. The case fatality rate (CFR) of LRTI in children under five years of age in Indonesia was 0.11%. Influenza was the most commonly reported viral etiological agent of LRTI in children under five years of age in Indonesia. Klebsiella pneumoniae was the most frequently reported bacterial agent of LRTI. Streptococcus pneumoniae showed the highest carriage rates. Conclusions: Surveillance and diagnostic studies are urgently needed and should be conducted in different parts of Indonesia to improve insight in the burden and etiology of LRTI in Indonesia. These data are pivotal to increase the effectiveness of public health strategies, including vaccination and prevention of antimicrobial resistance.

Background and Aim: The current phytobiotic industry is struggling to determine a proper sterilization method for an herbal formula that comprises multiple plant extracts. Hence, this study aims to investigate the effects of two sterilization methods of herbal formula on phytochemical compounds and antibacterial activity against mastitis-causing bacterial isolates. Materials and Methods: The herbal formula comprised the extracts of Piper betle leaves, Curcuma domestica, and Curcuma zanthorriza. We applied two sterilization methods – sterilization using 0.45 μM syringe filter and sterilization using an autoclave at 121°C for 15 min. After sterilization, we measured phytochemical contents (phenol and flavonoid) of the herbal formula. Using the disk diffusion method, the antibacterial susceptibility test of the sterilized herbal formula against mastitis-causing bacterial isolates was conducted. Tetracycline, erythromycin, and penicillin – common antibiotics for mastitis therapy in dairy farms – were used as standard antibiotics. Results: Compared with autoclave sterilization, syringe filter sterilization resulted in less (p<0.05) phenolic and flavonoid contents. Against Escherichia coli and Staphylococcus aureus, the filter sterilized herbal formula (E. coli: 65.9%-73%; S. aureus: 6.2%-18.1%) markedly reduced the antibacterial activity than the autoclave-sterilized herbal formula (E. coli: 2.1%- 3%; S. aureus: 4.5%-10.7%). Conclusion: This study establishes that autoclave sterilization of the herbal formula is the best sterilization method that exerts minimal adverse effects on the phytochemical compounds and could sustain the antibacterial efficacy against mastitis-causing bacteria. Hence, the herbal formula could be used as an alternative treatment for bovine mastitis.

Background: Lactoferrin is a glycoprotein of the transferrin family which has multifunctional properties and useful for clinical and commercial application. It has some advantages as an immune system modulation, antibacterial activity and antioxidant in infant and adult as well as in animal. Lactoperoxidase is one of the most prominent enzymes in milk and catalyzes the inactivation of a wide range of microorganisms. Both lactoferrin and lactoperoxidase are expressed in most biological fluids, including colostrum. Chemical components of colostrum may vary along the days after parturition. The study of lactoferrin and lactoperoxidase from dairy goat is very limited. This study aimed to isolate and identify characteristics (the molecular weight and concentrations) of lactoferrin and lactoperoxidase from Indonesian native Ettawa crossbred goat colostrum. Method: The isolation and purification of lactoferrin and lactoperoxidase was conducted by an ion-exchange chromatography (SP-sepharose). Other compositions of colostrum, protein, fat and lactose concentration, were also determined. Results: The result showed that lactoferrin and lactoperoxidase concentrations in goat colostrum on the first day (317.3 mg/L and 204 mg/L) were higher than colostrum on the second day (190,5 mg/L and 61.9 mg/L) postpartum. The molecular weight of lactoferrin and lactoperoxidase were 75 and 72 kDa. Protein, fat and lactose concentrations of colostrum on the first day postpartum (6.5%, 5.7% and 4.9%) were higher than those on the second day (4.9%, 4.4% and 4.1%). Conclusion: A high amount of lactoferrin and lactoperoxidase can be isolated from the goat colostrum on its first day of postpartum.

World TB report from World Health Organization (WHO) in 2017 informed that Indonesia was second country with TB case. Multi Drug Resistance pulmonary infection’s case in Indonesia were 12.000. Kariadi hospital is one of tertiary hospital for pulmonary MDR-TB treatment but, there is no study about risk factor of it yet, so it needed to find risk factors of MDR-TB pulmonary infection in Kariadi hospital. Cross Sectional design using secondary data from Medical Record  from January 1st -  December 31, 2017 with result of Mycobacterium tuberculosis on GeneXpert sputum examination. Bivariate analysis with Chi square test and multivariate analysis was done by multiple logistic regression. The p value was considered significant if <0.05, all analyzes were 2-tailed. Totally 110 patients were obtained during periode, 55 samples for case and 55 samples for control. There were correlation between smoking habit OR = 3,1 (CI 95% 1,1-8,7), malnutrition OR = 2,9 (CI 95% 1,3-6,3), contact with patient with MDR pulmonary TB infection OR = 12,0 (CI 95% 1,5-97,3), past treatment  OR = 81,7(CI 95% 23,4-285,2) and ≥6months past treatment OR = 94,5 (CI 95% 12,1-736,2. Risk factor that could influence together were contact with patient with MDR pulmonary TB infection OR = 34,5 (CI 95% 2,6-464,5), past treatment OR = 39,4 (CI 95% 8,3-186,3) and ≥ 6months past treatment OR = 12,4 (CI 95% 1,3-117,7). Risk factors for the incidence of pulmonary MDR TB infection are past contact with patient with MDR pulmonary TB infection, past treatment  and  ≥ 6months past treatment.

Intoduction: Sterile gauze is one of the medical devices that are often used to prevent infection. Several things, one of them is materials for packaging, can affect the sterility of gauze. Parchment paper is one of the packaging materials for sterilization. The study was done to analyze the sterility of gauze packed with parchment paper one layer and three layers on the growth of microorganism.Method: This study was an experimental study with a quasi-experimental design. Samples were 60 gauze packed with one layer parchment paper and 60 gauze packed with three layers of parchment paper. The sterility of sterile gauze tested at weeks 0, 2 and 4. Results: There was no significant difference in the sterility of gauze packed with 1 layer of parchment paper on the growth of microorganisms at 0, 2, 4 weeks (p = 0.126). No significant difference in the sterility of sterile gauze packed with 3 layers of parchment paper at 0, 2, 4 weeks (p = 0.675). There was a significant difference in the sterility of sterile gauze packed with parchment paper 1 layer and 3 layers on the growth of microorganisms (p = 0.002).Conclusion There is a significant difference of sterile gauze packed with parchment paper 1 layer and 3 layers against the growth of microorganisms. The sterility of the packaged sterile gauze with a layer of parchment paper is better than the three layers.
