Occurs E. coli resistance to class 3 cephalosporin class antibiotics and fluoroquinolone groups. The antibiotic resistance that occurs has narrowed the choice of therapy. This study aims to determine the effect of Actinomycetes isolates on proteolytic and amylolytic enzymes E. coli ATCC 25922. This research is experimental research, qualitative tests of protease and amylase enzymes from E. coli ATCC 25922 shown by clear zones around the growing colonies. The result of ANOVA One-Way test showed a significant difference in the width of clear zone, colony zone and PER and AER score with p-value < 0,05. This indicates that Actinomycetes isolates contain compounds that can act as inhibitors of protease and amylase enzymes from E.coli ATCC 25922. It is hoped that there will be research about the identification of Actinomycetes species isolates in Bogor Botanical Garden so that later can be cultivated and produced as an antibiotics alternative.

An alcoholic beverage contains ethyl alcohol or ethanol (C2H5OH)that is produced from fermentation or distillation of sugars. In many cases, either producers or consumers add ethanol with denaturated alcohol containing methanol (CH3OH) as an additive. Methanol can cause blindness and induce comas, and it is deadly in high doses. This study aimed at investigating the presence of methanol or methyl alcohol in alcoholic beverages sold in Palembang, Indonesia. Seventeen samples collected from small shops and supermarkets were taken by accidental sampling. A chromotropic acid method was used to examine the presence of methanol. The results showed that there were 18% of the samples was positive, and 82% was negative. Based on alcohol content, the research showed that all (100%) samples of group A were negative; 33% of group B was positive, and 33% of group C was positive. The study indicated that methanol was still present in alcoholic drinks sold in markets. The government should inform the society that denatured alcohol contains methanol and, therefore, should not be feasible to consume.

Typhoid fever is a significant public health burden in low-income countries caused by Salmonella enterica serotype typhi (S.typhi). Clinical manifestations of typhoid fever are varied and non-specific, making the diagnosis difficult. Using oxgall for pre-incubation as a selective culture medium before amplification of Real-time PCR (RT-PCR) in wholeblood produces a fast and sensitive diagnostic. The purpose of this study was to know the performance oxgall-precultured Real-time PCR for detection of Salmonella sp.. Prior to the sample process, spike method optimization was performed to find out that the reagents were well used for clinical specimens. In the sample process, blood samples from 30 Widal-positive patients were collected for this study . Venous blood samples from typhoid fever patients were taken on the day of diagnosis; 5 ml for blood culture, and 5 ml for RT-PCR. The bacteria were grown in oxgall 10% (standard microbiological laboratory clinics) and incubated for 6 hours (37° C) before bacterial DNA was isolated for RT-PCR detection. The results showed that reagen of RT-PCR is good used for a clinical sample and a blood culture was better than RT-PCR using oxgall (positive blood culture results over 24 hours). This suggests that there is a need for further research on the duration of incubation and oxgall concentrations in RT-PCR and the selection of clinical samples.

The emergence of multi-drug resistant (MDR) bacteria has endangered the efficacy of antibiotics treatment of pathogenic bacteria worldwide. The aim of this research was to investigate the incidence of Salmonella enterica serovar Typhi in Duhok city, Iraq. Specimens of blood and stool were recruited from 267 patients. S. Typhi isolates were diagnosed depending on morphology, biochemical and serological tests. S. Typhi isolates were tested for their antibiotic resistance. Multi-drug resistant S. Typhi isolates were conjugated with E. coli HB101. The plasmid profile of transconjugants was investigated. 15/267 (5.6%) S. Typhi isolates were identified. Based on their biochemical tests, S. Typhi isolates were categorized into two biotypes (I, 26.66% and II, 73.33%). Four resistance patterns were observed. The resistant pattern to ampicillin and tetracycline was the higher (46.6%). Conjugation experiment showed that all antibiotic markers were transferred from S. Typhi to E. coli HB101 with a conjugation frequency of (0.38×10-5). 13.3% of the S. Typhi isolates were multi-drug-resistant resistant and had two small plasmids. Transconjugants E. coli acquired the resistance from the multi-drug resistant S. Typhi. Antibiotics treatment of the pathogens could be hindered by the constant rise of multi-drug-resistant. Further studies are needed to study the mobile genetic elements and their contribution to antibiotics resistance.
