Typhoid fever, caused by the human restricted pathogen Salmonella Typhi, remains a major global public health concern. Even after successful treatment, approximately 3-5% of patients with typhoid fail to clear the bacteria within one year and become chronic carriers. Most typhoid carriers have gallstones in their gallbladder, and biofilm formation on gallstones is highly correlated with chronic carriage. This study’s goal was to identify asymptomatic typhoid carriers in an endemic setting in Kenya, and to compare acute versus chronic isolates. A cohort of typhoid fever patients identified through blood and/or stool culture, and their household contacts, were followed up after treatment to detect longitudinal S. Typhi stool shedding. An abdominal ultrasound scan was used to identify individuals with gallstones. A total of 32 index patients and 32 household contacts were successfully followed-up. Gallstones were detected in 4 cases and 1 household contact. The duration of S. Typhi shedding was significantly longer in individuals with gallstones compared to those without, P<0.001. Eighty-three (83) S. Typhi strains were tested for susceptibility to commonly used antimicrobials and examined by in vitro biofilm formation assays. Out of 37 infected individuals, 32.4% had infections caused by multidrug resistant (MDR) S. Typhi strains and only 18.9% were infected by susceptible strains. Non-MDR strains formed significantly better biofilms in vitro than the MDR strains (P<0.001). This study provides data on S. Typhi chronic carriage that will influence public health approaches aimed at reducing typhoid transmission and the burden of infection.

Background The emergence and spread of carbapenem-resistant gram-negative bacteria pose a serious threat to human health. Currently, little is known about the molecular mechanisms underlying carbapenem -resistance and their prevalence among APEC in Egypt. The aim of this study was to detect APEC in clinically diseased broiler chickens collected from broilers farms located at Dakahalia governorates, asses their virulence –associated genes, detect the antimicrobial susceptibility of recovered isolates and to detect genes encoding carbapenemase resistant. Methods A total of 100 organ tissue samples subjected to conventional culture technique for isolation of E. coli. The confirmed E. coli were subjected to disc diffusion method for detection their susceptibility to antimicrobials. Polymerase chain reaction (PCR) was used for detection of APEC virulence genes (hlyA, iutA, ompT, iss, iroN) and six carbapenem- resistant genes namely, blaIMP, blaVIM, blaKPC, blaOXA-48 blaGES and blaNDM,. Results Forty isolates were confirmed to be E. coli among them, three or more APEC virulence- genes were detected from all isolates. The hlyA gene was detected in 90% (36/40), iroN in 95% (38/40), ompT in 97.5% (39/40), iutA in 92.5% (35/40) and iss was detected in 95% (38/40) of APEC isolates The tested isolates exhibited a remarkable resistance to ampicillin (97.5%), cefuroxime (92.5%), clindamycin (90%), chloramphenicol (62.5%), doxycycline (45%), amikacin (25%) and ciprofloxacin (12.5%). While, the retrieved isolates displayed 100 % sensitivity against imipenem, meropenem, ertapenem, ceftazidime and colistin. Concerning carbapenemase-encoding genes, blaIMP, blaVIM, blaKPC, blaOXA-48, blaGES couldn’t be detected among the E. coli isolates, while, blaNDM was confirmed in three isolates . Conclusion The detection of NDM as one of the carbapenem resistant genes reveals that the resistant strains are not only capable of infecting humans, but that carbapenams- resistant E. coli (CREC) has also started to pose a threat to poultry farm and other livestock animals. This may give rise to worries that these food-carrying creatures could infect humans or colonize them.

Background Overuse and abuse of antibiotics resulted in emergence of multidrug-resistant organisms (MDRO), increased rates of invasive candidiasis, prolonged hospital stay, NEC (Necrotizing enterocolitis), LOS (Late onset sepsis) or death. Restriction of the prescription, switching to a narrower spectrum and stopping antibiotics when not needed are some of the major approaches to antibiotic stewardship. Methods We identified restricted antimicrobials and devised an antimicrobial justification form. Clinicians needed to fill the form before prescribing restricted antimicrobials thereby comparing the antimicrobial usage pattern before and after the introduction of form. Babies enrolled before the introduction of the justification form were labelled as Group 1, and as Group 2 after justification form. The HIC (hospital infection control) staff nurse paid daily visits to NICU to monitor number of babies started on restricted antibiotics and whether the forms were duly filled or not. Any lag would be intimated to the Head HIC team for rectification. Any change of antibiotic within the restricted group also warranted justification. Culture report notified within 48 – 72 hrs so as to facilitate the stoppage of antibiotics in case of negative culture. Results There was a statistically significant reduction in the usage of restricted antimicrobials in the Group B as compared to Group A 150 (40.54%) vs 190 (49.35%) (p = 0.01). There was a statistically significant increase in the % of babies de-escalated from high end antimicrobials in Group B as compared to Group A 90 (60%) vs 56 (29.47%) (p = <0.0001). Duration of restricted antimicrobials reduced from 13.78 ± 2.7 days in Group A to 9.9 ±1.8 days in Group B (p = <0.0001). No difference in the number of babies started on any antibiotic between both the groups (p = 0.1). Conclusion Introduction of the antibiotic justification form as a part of antimicrobial stewardship program resulted in an overall reduced usage of restricted antimicrobials along with rapid de-escalation.

Background Self-medication (SM) can be defined as the use of drugs to treat self-diagnosed disorders or symptoms, or the intermittent or continued use of a prescribed drug for chronic or recurrent disease or symptoms. A number of individuals in developing countries do not attend physicians for their illnesses; instead they commonly use self-medication. Self-medication could be using drugs existing in home like over the counter (OCT) drugs, traditional medicine, prescription only drug. Self-medication is not always bad, hence for the over the counter drugs it is beneficial. Inappropriate storage and use of medicines at home could have a direct influence on public health, the environment and the health-care services and it increases the risk of self-medication. Objective To assess the practice of self-medication and drug storage among South Sudanese community in Addis Ababa. Materials and Methods A cross sectional study design was conducted in Addis Ababa city from April 22 to April 26/2019. Data was collected by semi structure-questionnaire consisting questions on general demographic, socio-economic as well as on perceived illness/ symptoms in the past four weeks and actions taken for it. The data collected was screened before it is analyzed. Data analysis was done by using calculator. Results From the total 297 respondents 286 (96.2%) had reported self-medication in the last one month before the study period. The most common types of ailments for which the respondents reported to have practiced self-medication were cough, cold and sore throat 90(30.3%), followed by headache 66(22.2%), diarrhea 52(17.5%) ,abdominal pain 47(15.8%), fever 21(7.07%) and vomiting 10(3.3%). The reasons given for self-medication were; the illness was minor 226(76%) and previous experiences with similar ailments 31 (10.4%) were found to be the two major reasons given by the respondents for self-medication in this study. The majority of the respondents 242(81.4%) who practiced self-medication obtained information on self-medication from friends and 29(9.7%) obtained information from family members. The most frequently used group of drugs used for self-medication were analgesics/antipyretics 177(59.5%) and antimicrobial which account 75(25.2%) each followed by antihelmenthics 24(8.08%).The main source of drugs for SM was in pharmacy 220(74.07%) followed by leftover drugs 41(13.8%) while drug retail outlet, and neighbors and relatives were the suppliers to 12.13% respondents each. Conclusion and Recommendation A significant number of respondents (96.2%) use S/M from those perceived illness. Majority of the self-medicated individuals used due to minor illness. The most common category of drugs used was analgesics/antipyretics and antimicrobials. And the reason reported for using S/M was minor illness and previous experience with the illness. Most of respondents obtained drugs easily from pharmacy. So, pharmacies are the major sources of drugs used for S/M. The increased of drugs storage to treat similar illness/symptom and drugs left over from previous use contribute to the increase in the S/M practice. Common drugs store reported by respondents who store modern drugs were analgesic/antipyretic. Most of the respondents stored the drug in locked cabinets. A lot is need to be done in educating the public including the health care providers on the type of illnesses that can be self-diagnosed and self-treated, the type of drugs to be used for S/M, and the proper use of drugs. During dispensing of drugs emphasis should be given to all drug consumers and dispenser because of resistance and side effects of drug is the main challenging problem even in the world. Food, Medicines and Healthcare Administration and Control Authority (FMHACA) needs to effectively implement laws on drug handling and dispensing so as to take necessary measures on illegal providers of drugs.

Introduction Antimicrobial stewardship (ASP) is of the utmost importance as a way to optimize the use of antimicrobials to prevent the development of resistance and improve patient outcomes. So, it is worthwhile to assess the knowledge, attitude and awareness regarding antimicrobial stewardship in hospitals. Objective The aim of this study is to assess knowledge, attitudes and practices (KAP) of prescribers towards antimicrobial stewardship at hospitals in Khartoum state and to identify the associations between prescriber’s demographic information and their knowledge. Methodology This descriptive cross-sectional study multi-centered study conducted in 10 hospitals at Khartoum state -Sudan, during period from November to December 2018. Study population included all prescribers who is available at study’s hospitals during study period and willing to participate in the study. A self-administered questionnaire addressing participants’ knowledge, attitudes, and practice (KAP) regarding antibiotic resistance and ASP distributed in the selected hospitals among attending house-officers, registrars and consultants completed then analyzed. Results Of the 294 medical staff targeted, 287 responded to the survey (response rate 97.6%). Only (26.4%) were familiar with the term ASP and (31.5%) claimed that it is effective in reducing resistance. (43.0%) of respondents believe that ASP play vital role on antibiotic prescribing. Only (9.5%) had ASP in their hospital and (13.5%) having policy and team. (45.3%) of participants had good level of knowledge about antimicrobial stewardship, but majority show negative attitude (63.1%), and poor practices (92.0%) regarding ASP. There was no observed correlation between knowledge and attitude, knowledge with practice (p-value ≥ 0.05). Only attitude with practice shows significance correlation (P=0.0001), which means that prescribers with positive attitude had the better practices towards antimicrobial stewardship. Age, occupation and experience are the only significant predictors of prescriber's knowledge and attitude towards antibiotic stewardship, while no association between these factors and practice. Conclusion The present study concludes that the knowledge of prescribers regarding ASP is moderate and their attitude is negative. Unfortunately, practices regarding ASP were poor, despite, the good knowledge regarding the effects of ASP on antimicrobial resistance.
