Abstract

Contamination of pathogenic bacteria in food can lead to the emergence of foodborne disease. One of foodborne disease which often occurs in some developing countries such as Africa, Southeast Asia, and Latin America is cholera which is caused by Vibrio cholerae. The disease is transmitted through beveragesand food, especially contaminated seafood. V. cholerae has several virulence factors including the outer membrane protein W (ompW) and cholerae toxin (ctx).The ompWacts as a protective barrier and can also be used as a marker specific species of V. cholerae and cholerae toxin is an enterotoxin responsible for the incidence of diarrhea in a cholera outbreak produced by pathogenic V. cholerae. This study was an observational study to determine the level of contamination of V. cholerae by detecting the outer membrane protein W (ompW) and cholerae toxin subunit A (ctxA)gene of V. cholerae in shrimp and shellfish sold at Kedonganan fish market. Samples were taken using total sampling technique and obtained 24 samples consisting of 14 shrimp samples and 10 shellfish samples. Samples were examined using culture methods and biochemical tests, and then further tested using Duplex Polymerase Chain Reaction (dPCR) to detect ompW and ctxA gene. The dPCR assay results showed 8 out of 14 (57.1%) samples from shrimp and 1 out of 10 (10%) samples from the shellfish positive carried ompW gene, and found no positive samples carrying the ctxA gene in samples derived from shrimp and shellfish. Chi square test analysis results indicated contamination of V. cholerae in shrimp washigher than shellfish based on ompW gene (p<0.05). It can be concluded that the shrimp and shellfish at Kedonganan fish market are contaminated by V. cholerae. Further research is needed to detect the virulence factors besides ompW and ctxA ofV. cholerae in seafood.

Abstract

Introduction: Breast cancer is the most common type and lethal cancer affecting women. Meanwhile, vinorelbine is one of the chemotherapy agents used for luminal and non-luminal breast cancer. Therefore, this study aims to determine the survival difference between patients with luminal and non-luminal subtype breast cancer treated with vinorelbine.Methods: This study was a retrospective cohort. Women with breast cancer treated with vinorelbine were classified based on estrogen receptor (ER), progesteron receptor (PR), human epidermal growth factor receptor-2 (HER-2) markers, and subtypes. The subjects were followed up to chemotherapy visits with vinorelbine recorded in the medical record. The survival analysis between subtypes was analyzed by the Kaplan-Meier curve.Results: : One hundred women were obtained with a mean age of 52.36 ± 10.45 years. Based on immunohistochemistry, 60% were ER-positive, 53% were PR positive, and 57% were HER-2- positive. Based on the subtype, 67% were luminal, while 33% were non-luminal. All subjects had a mean survival duration of 155.38 days (95% CI 128.05-182.71). The stratified survival analysis showed a significant difference in survival duration based on HER-2 marker and subtype. The subjects with HER-2 positive survived longer with a mean of 203.37 days (190.72–216.02) than those with HER-2 negative with a mean of 90.10 days (65.68-114.53) (p<0.001). In addition, the subjects with the luminal subtype survived longer with a mean of 174.84 (142.72-206.94) than those with non-luminal with a mean of 90.10 (65.68-114.53) (p = 0.04).Conclusion: There was a significant difference in survival duration between women with breast cancer treated with vinorelbine chemotherapy who were HER-2 positive, HER-2 negative, and luminal and non-luminal subtypes.

Abstract

Introduction: The increasing number of resistance cases of Methicillin-resistant Staphylococcus aureus (MRSA) and Multidrug-resistant Pseudomonas aeruginosa (MRPA) to common antibiotics has called the need for new modalities to combat these resistance problems. The ingredients that are thought to influence the growth of MRSA and MRPA are Tahi Kotok flowers (T. erecta) and Jamblang leaves (S. cumini). This study aimed to evaluate the effect of the combined Tahi Kotok flowers and Jamblang leaves ethanol extract on the growth of MRSA and MRPA bacteria.Methods: The research was conducted as a true experimental design using a post test only control group design. The combination of ethanol extract in several concentrations (25%, 50%, 75%, 100%) were tested on MRSA ATCC 3351 bacteria and MRPA bacteria cultured on agar media. The data obtained are the results of laboratory observations with the disk diffusion methods which are then statistically analyzed parametrically using the SPSS application which is shown as mean ± SEM.Results: The inhibitory activity of T. erecta flower extract with MRSA and MRPA bacteria was found. The largest inhibition zone diameter was at 75% extract concentration, with inhibition zones of 17.25 ± 1.25 cm and 11.25 ± 0.50 cm, respectively. The largest inhibition zone of S. cumini leaf experiment with MRSA bacteria was at concentration of 75 percent, which resulted in a 9.50 ± 0.57 cm inhibition diameter. In MRPA bacteria, however, there was no inhibition zone. At a concentration of 75 percent, the combination of T. erecta flower extract and S. cumini leaf had the highest inhibitory activity against MRSA bacteria, but had no inhibitory activity against MRPA bacteria.Conclusion: The concentration of extract combination in 96% ethanol influences the diameter of the MRSA inhibition zone, whereas in MRPA no inhibition zones were generated from this in vitro experiments. Latar Belakang: Meningkatnya kasus resistensi bakteri Methicillin-resistant Staphylococcus aureus (MRSA) dan Multidrug-resistant Pseudomonas aeruginosa (MRPA) terhadap antibiotik menyebabkan perlunya modalitas baru sebagai potensi untuk mengatasi masalah resistensi tersebut. Salah satu bahan yang diduga berpengaruh terhadap pertumbuhan MRSA dan MRPA adalah bunga Tahi Kotok (T. erecta) dan daun Jamblang (S. cumini). Penelitian ini ditujukan untuk melihat adanya pengaruh kombinasi ekstrak etanol bunga Tahi Kotok dan daun Jamblang terhadap pertumbuhan bakteri MRSA dan MRPA.Metode: Penelitian ini menggunakan rancangan true experimental post test only control group design. Kombinasi ekstrak etanol dalam beberapa konsentrasi (25%, 50%, 75%, 100%) diujikan pada bakteri MRSA ATCC 3351 dan MRPA yang dikultur pada media agar.

Abstract

Background: Streptococcus pneumoniae causes broad-spectrum infections from mild to severe with high morbidity and mortality rates in almost all of the world, namely pneumonia and meningitis. This bacterium has virulence factors that help their survival, one of which is biofilms. Biofilms help Streptococcus pneumoniae become resistant to antibiotics; thus, treating infections caused by these bacteria is difficult to treat. This study aims to determine the biofilm production ability of Streptococcus pneumoniae isolated from the Clinical Microbiology Laboratory of Sanglah General Hospital, Denpasar, Bali, Indonesia using the tissue culture plate method.Methods: The research design used was a descriptive observational study with cross sectional type. The clinical isolate of Streptococcus pneumoniae was isolated from the Clinical Microbiology Laboratory of Sanglah General Hospital. Biofilm formation was measured by the tissue culture plate method and carried out at the Microbiology Laboratory of the Faculty of Medicine, Udayana University. Data were analyzed using SPSS version 20 for Windows.Results: Most of the specimens were collected from blood (59.37%), followed by sputum (31.25%), and others (9.38%). It was found that 1 of 32 (3.10%) clinical isolates could form a biofilm with a strong formation category (the optical density value> 0.38). In contrast, the rest did not form biofilms with an optical density value of ?0.095.Conclusions: Not all clinical isolates of Streptococcus pneumoniae isolated from the Clinical Microbiology Laboratory of Sanglah General Hospital Denpasar were able to form biofilms, suggesting that other virulence factors also play a role in pneumococcal infection. However, a molecular approach is necessary for the detection of genes encoding biofilm-producing isolates in future studies.

Abstract

Background: Klebsiella pneumoniae is a common cause of healthcare-associated infections (HAIs), and has a high level of resistance to antibiotics first, second, extended-spectrum cephalosporins, and monobactam which are a serious threat to public health worldwide. Besides, it is known that this bacterium can form biofilms as virulence factors that contribute to drug resistance. This study aims to determine the antibiotics susceptibility patterns and the capacity of K. pneumoniae to form biofilms.Methods: K. pneumoniae was isolated from clinical specimens (urine, sputum, pus, blood, and others) for the period 2018-2019. Bacterial identification and antibiotic susceptibility testing were performed using the Vitek Compact 2 (bioMérieux®) test in the Clinical Microbiology Laboratory of Sanglah General Hospital. Biofilm formation was checked using the tissue culture plate method (TCP). Data were analyzed using SPSS version 20 for Windows.Results: Most of Extended Spectrum ?-Lactamase (ESBL)-producing K. pneumoniae showed resistance to antibiotics. The susceptible profiles were only towards ertapenem (97.50%), meropenem (97.50%), amikacin (95.00%), and tigecycline (87.50%). The TCP method detected 72 (90.00%) as biofilm producers among 80 clinical isolates, while 8 (10.0%) as non-biofilm producers. Among the biofilm-producer bacteria, there were 6 (7.50%) as strong, 37 (46.25%) moderate, and 29 (36.25%) weak biofilm-producer isolates.Conclusions: Most ESBL-producing K.pneumoniae clinical isolates in Sanglah General Hospital demonstrate multiple resistance to antibiotics and as biofilm producers. However, further research is needed to be conducted using a molecular approach to see the ESBL- and biofilm-encoded genes.
