Abstract

Introduction: Escherichia coli is a Gram-negative bacteria and a most cause of nosocomial infections. Bacteria has the ability to form biofilm that may cause antimicrobe resistance. This biofilm protects the microbes from environmental conditions which make it the most cause of nosocomial infections including urinary tract infection and the infections resulted from the use of medical instruments. The aim of this experiment is to observe the presence of cefotaxime and ceftriaxone antimicrobial resistance in E. coli as a cause of biofilm formation. Method: This study conducted three experiments of E. coli sensitivity test on cefotaxime and ceftriaxone, E. coli resistance test after a 48 hours incubation, and optical density measurement using iMark™ ELISA Microplate Reader. Result: The results of sensitivity experiment with antibiotic cefotaxime and ceftriaxone disk showed sensitive result in wild-type E. coli and E. coli ATCC while after 48 hours incubation E. coli ATCC remains sensitive and in wild-type E. coli result are three intermediates, one sensitive and other than that it’s all change to resistance. The third experiment results were obtained from ELISA then classified into three categories. In E. coli ATCC 1 and 2, the results are mostly in high category (OD >0.240). The OD in E. coli 1 is mostly high, while results from E. coli 2 consists of one bacterium in weak category (OD <0.120), four in moderate category (OD 1.20 – 0.240), and three in high category. Conclusion: It can be concluded that E. coli resistance test in cefotaxime and ceftriaxone after 48 hours’ incubation are mostly resistant in wild-type E. coli but sensitive in E. coli ATCC.

Abstract

Introduction: HIV AIDS patients who have a CD4 count < 200 cells/uL often complain of respiratory symptoms (Wallace, 1993). The complaint was shortness of breath (62%). Opportunistic infections (IO) in HIV patients are also brought on by a decreased CD4 count of 200 cells/uL (Peters, 2007). HIV/AIDS patients with CD4 < 200 cells/uL have a risk of death of 10.399 (Kusumaadhi, 2021). This study aims to determine the association between CD4 cell count with mortality in HIV patients with shortness of breath at Cendana, Dr. Soetomo General Academic Hospital Surabaya, during the period of January–December 2020.Methods: This study used a cross-sectional retrospective design. The population in this study were patients diagnosed with HIV at Cendana, Dr. Soetomo General Academic Hospital, using a total sampling technique. The variables studied were the CD4 counts as the independent variable, and the mortality of HIV patients with dyspnea as the dependent variable. The sample in this study must meet the inclusion criteria, namely, the sample must have a history of CD4 counts in their medical record in the last 2 to 3 months while in Cendana, Dr. Soetomo General Academic Hospital. Secondary data from medical record data in Cendana, Dr. Soetomo General Academic Hospital, was used for the research from January to December 2020. Results: A total of 128 HIV patients with dyspnea and a history of CD4 counts in the previous 3 to 4 months were included in the study: 79 (61.7%) males and 49 (38.3%) females. The most common age groups were 31–40 years (33.6%), 20–30 years (32.0%), 41–50 years (23.4%), and > 60 years (2.4%), with no patients under the age of 20. The distribution of the most opportunistic infections were: pneumocystis pneumonia (n = 62), tuberculosis (n = 49), and bacterial pneumonia (n = 17). Patients lived (n = 79) and died (n = 49) in total.Conclusion: There was no significant association between CD4 count and mortality in HIV patients with dyspnea (p-value 0.084 > 0.05).
