Urinary tract infection (UTI) is a common cause of illness in people of all age groups. The increasing trend of antibiotic resistance is now a concern worldwide. The present study was conducted to determine the antibiotic resistance pattern of Gram negative pathogenic isolated from UTI cases in Sirajganj district. A total of 297 uropathogens were included in this study of which 66 (22.2%) were isolated from male patients and 231 (77.8%) from female patients. Escherichia coli (52.9%) was found to be the predominant pathogen followed by Klebsiella spp. (22.9%), Proteus spp. (4.7%), Psudomonas spp. (4.4%), Enterobacter spp. (2.4%), Citrobacter spp. (3%) and Morganella spp. (5.7%). Most of the uropathogens were resistant against Ampicillin (AMP). Meropenem was the most effective antibiotic with resistance between 0 and 15.1% of the tested isolates. However, the trend of antibiotic resistance can vary with the change in the environmental and socioeconomic conditions. Accurate diagnosis of UTI and determination of antibiotic sensitivity pattern is important for selection of appropriate drug for effective treatment.

Introduction : Neonatal sepsis remains an important cause of neonatal morbidity and mortality in NICU setup and a major challenge for the neonatologists. The prevalent organisms and their antibiotic resistance patterns evolve with time and with the usage of antimicrobials.Aims and Objectives : To analyze the bacteriological profile and antibiotic resistance patterns of proven neonatal sepsis cases in Dhaka Shishu Hospital.Materials and Methods : The study was Prospective observational study. All the clinically suspected cases of Neonatal Sepsis admitted to the Neonatal word from January 2015 to December 2015 were included in the study. Clinically suspected cases of neonatal sepsis further evaluated with blood cultures and antibiotic susceptibility testing using the Kirby Bauer disc diffusion method. Data was collected for the following variables: Demographic profile, haematological profile, blood culture result and antibiotic sensitivity patterns.Results : Total 96 cases clinically suspected neonatal sepsis were included in the study. Among them 29 cases (30.21%) was culture positive septicemia. Klebsiella pneumoniae was the most common isolate accounting for 31.03% cases followed by Escherichia coli 27.59%. In Klebsiella infection most common sensitivity were Imipenum and Ciprofloxacin which were 77.78 and 33.33% respectively. In E.coli common sensitive drugs were Imipenum and Amikacin. In serratia common sensitive drugs were Imipenum, Netlmicin and Ciprofloxacin.Conclusion : K. pneumoniae was the most common pathogen. Most common sensitivity was Imipenum, Amikacin, Ciprofloxacin, Gentamicin, Netlmicin, and Ceftazidime,.Northern International Medical College Journal Vol.8(1) July 2016: 174-177

Targeted empirical antibiotic therapy based on local microbiology and antibiotic resistance patterns is essential for the treatment of empyema thoracis. Our retrospective review of 105 pleural empyema culture and sensitivity reports aimed at determining the causative microorganisms and their antimicrobial resistance pattern. Of 105 pleural aspirate samples, 46 (43.8%) were positive on culture. Gram-negative organisms (n = 43) were the predominant isolates, the commonest of which was Klebsiella pneumoniae. It was concluded that empyema thoracis is predominantly caused by Gram-negative organisms in our locality. This should guide protocols on the initiation of empirical therapy.

The aim of this study was to detect oral bacteremia and offer the antibiotic resistance patterns. Bacterial resistance pattern was evaluated in 50 patients. A spectrophotometer device equipped with UV and electrophoresis of the extracted samples on agarose gel for antibiogram test were used. PCR test 15 minutes after tooth extraction showed that bacterial strains were extracted from 16 patients. Lactobacillus, Enterococcus faecalis (E. faecalis), Streptococcus sanguinis (S. sanguinis), Streptococcus salivarius (S. salivarius), and Streptococcus mutans (S. mutans) were extracted from 5, 4, 4, 4, and 6 patients. 100% of Lactobacillus, E. faecalis, S. sanguinis, S. salivarius, and S. mutans were sensitive to tigecycline. Most of the Lactobacillus antibiotic resistance was against tetracycline and ciprofloxacin. Antibiotic resistance in S. salivarius was observed in 75% of the cases against piperacillin-tazobactam, ciprofloxacin, and cefotaxime, while in S. mutans was 84% of the cases against ceftriaxone. The results of the current study showed that tooth extraction causes bacteremia before, during, and after tooth extraction. Generally, the highest antibiotic resistance occurred against tetracycline, ciprofloxacin, and ampicillin-sulbactam. In most cases, the bacteria showed partial resistance to these antibiotics; however, tigecycline showed 100% efficacy on all types of bacteria. Streptococcus strains (salivarius, mutans, and sanguinis) were sensitive to most of the antibiotics while antibiotic sensitivity was less evident in Lactobacillus and E. faecalis. Antibiotic resistance has become a critical issue, since it leads to treatment failure when there is a need for antibiotic therapy.

Clostridium difficile isolates (n=149) collected in south-east Scotland between August and October 2005 were typed by four different methods and their susceptibility to seven different antibiotics was determined. The aims were to define the types of strain occurring in this region and to determine whether there were any clonal relationships among them with respect to genotype and antibiotic resistance pattern. Ribotyping revealed that 001 was the most common type (n=113, 75.8 %), followed by ribotype 106 (12 isolates, 8.1 %). The majority of the isolates (96.6 %, n=144) were of toxinotype 0, with two toxinotype V isolates and single isolates of toxinotypes I, IV and XIII. PCR and restriction analysis of the fliC gene from 147 isolates gave two restriction patterns: 145 of pattern VII and two of pattern I. Binary toxin genes were detected in only three isolates: two isolates of ribotype 126, toxinotype V, and one isolate of ribotype 023, toxinotype IV. S-types showed more variation, with 64.5 % (n=40) of the common S-type (4939) and 21 % (n=13) of S-type 4741, with six other S-types (one to three isolates each). All ribotype 001 isolates were of the same S-type (4939), with three isolates of other ribotypes being this S-type. No resistance was found to metronidazole or vancomycin, with resistance to tetracycline only found in 4.3 % of the isolates. A high proportion of isolates were resistant to clindamycin (62.9 %), moxifloxacin, ceftriaxone (both 87.1 %) and erythromycin (94.8 %). Resistance to three antibiotics (erythromycin, clindamycin and ceftriaxone) was seen in 66 isolates, with erythromycin, ceftriaxone and moxifloxacin resistance seen in 96 isolates. Resistance to all four of these antibiotics was found in 62 isolates and resistance to five (the above plus tetracycline) in one isolate: a ribotype 001, toxinotype 0 strain. Whilst ribotype 001 was the most commonly encountered type, there was no evidence of clonal relationships when all other typing and antibiotic resistance patterns were taken into account.

Abstract Objection : Coagulase-negative staphylococci (CoNS) are considered opportunistic pathogens which capable of producing several toxins, enzymes and also resistance genes. The current study aimed to determine the occurrence of different hemolysins and patterns of antibiotic resistance among CoNS species. Results : The highest frequency of antibiotic resistance was observed against cefoxitin in 49 isolates (53.8%), and the lowest resistance was against novobiocin in 5 isolates (5.5%). None of the isolates were resistant to vancomycin. The prevalence of hla, hla_yidD, hld, and hlb genes were determined as 87.9%, 62.6%, 56%, and 47.3%, respectively. The hla/yidD and hld genes were detected in 69.4% of S. epidermidis and the hla gene in 94.6% of S. haemolyticus ; hlb gene was detected in 53.1% of the S. epidermidis isolates. mecA gene was identified in 50 (55%) of the CoNS isolates. In conclusion, the results of statistical analysis showed that the hld gene had a significant association with resistance to levofloxacin and erythromycin and the hlb with clindamycin resistance. The results of this study showed that there is a significant relationship between hemolysin encoding genes and antibiotic resistance patterns; therefore, detection of virulence factors associated with antibiotic resistance has become a significant issue of concern.

ABSTRACT The Pseudomonas genus, which includes environmental and pathogenic species, is known to present antibiotic resistances, and can receive resistance genes from multi-resistant enteric bacteria released into the environment via faecal rejects. This study was aimed to investigate the resistome of Pseudomonas populations that have been in contact with these faecal bacteria. Thus, faecal discharges originating from human or cattle were sampled (from 12 points and two sampling campaigns) and 41 Pseudomonas species identified (316 isolates studied). The resistance phenotype to 25 antibiotics was determined in all isolates, and we propose a specific antibiotic resistance pattern for 14 species (from 2 to 9 resistances). None showed resistance to aminoglycosides, tetracycline, or polymyxins. Four species carried a very low number of resistances, with none to β-lactams. Interestingly, we observed the absence of the transcriptional activator soxR gene in these four species. No plasmid transfer was highlighted by conjugation assays, and a few class 1 but no class 2 integrons were detected in strains that may have received resistance genes from Enterobacteria. These results imply that the contribution of the Pseudomonas genus to the resistome of an ecosystem first depends on the structure of the Pseudomonas populations, as they may have very different resistance profiles.

Abstract Background Resistant Gram-negative pathogens (GNP) are common causes of genitourinary tract infections (GUI) often requiring outpatient parenteral antibiotic therapy (OPAT). Data are sparse regarding antibiotic resistance of GNP in patients (pts) treated with OPAT. We analyzed GNP of GUI pts treated in Infectious Disease OICs over a 3-year period stratified by location prior to OPAT. Methods Records from 18 POICs were queried for GUI pts with ≥1 GNP receiving OPAT from 2018 to 2020. Demographics, pt location prior to OPAT, infection type, year of therapy, and GNP were recorded. Antibiotic resistance patterns were defined as extended-spectrum beta-lactamase (ESBL) or multi-drug resistant (MDR). Chi Square and Fisher’s exact test were used to determine if ESBL status was associated with GNP or location prior to OPAT (hospital vs. community). The Cochran-Armitage test was used to analyze temporal trend in ESBL expression. Statistical significance was defined as P< 0.05 for all tests. Results A total of 634 GNP were identified in 601 pts (mean age: 64±16, 58% female). Infections were 75% complicated urinary tract infection, 20% pyelonephritis, and 5% prostatitis/other. Overall, 56% (n=339) were treated directly from the community and 44% (n=262) following hospital discharge. GNP isolated were 56% E. coli, 19% Pseudomonas spp., 16% Klebsiella spp. and 9% others. Of the 611 GNP with potential to express ESBL, 43% (n=265) were ESBL producers (Table 1). Significantly more ESBL-producing GNP occurred in pts discharged from a hospital prior to OPAT compared to the community (53% vs. 36%, P< 0.001). Overall, the incidence of MDR constituted 36% (n=231) of GNP, which did not differ by location prior to OPAT. Evaluation of ESBL incidence by year showed a significant increase from 2018 to 2020 (P=0.03). Although a slight increase in MDR was noted from 2018 to 2020, this was not significant (Figure 1). Table 1. Frequency of ESBL and MDR by Location prior to OPAT Figure 2. Prevalence of ESBL producers and MDR Pathogens by Year Conclusion Resistant GNP were observed in the OPAT setting for GUI with both ESBL and MDR pathogens. We saw a significantly higher rate of ESBL with GNP from hospital discharged pts compared to community-acquired infections and an increase in the overall incidence of ESBL over time. Management of Gram-negative genitourinary infections in the OPAT setting requires close monitoring of emerging resistance patterns. Disclosures Kimberly A.

Background: Bacterial conjunctivitis is often observed in newborns as well as in other age groups. It has been associated with several organisms that differed in their relative importance and varied in their response to ophthalmic antibiotics. Objectives: The aim of this study was to investigate bacterial conjunctivitis of adult patients by determine the specific bacterial causes and determine the  ophthalmic antibiotic resistance patterns for the bacterial isolates from conjunctivitis patients in Sana’a city, Yemen.  Methods: Total 521 bacterial swabs obtained from adult patients with suspected bacterial conjunctivitis introducing to the ophthalmology clinics in the tertiary hospitals in Sana’a city, Yemen between September 2016 and October 2017 were investigated for bacteriological agents and antibiotic susceptibility . The clinical samples culturing, and microbiology diagnosis were done at National Center of Public Health laboratories Sana’a (NCPHL).  Result: Total 521 swab results from conjunctiva were performed, of which 206 (39.5%) were deemed positive for bacterial culture. The isolation rate by bacteria species ranged from 0.5% to 28.2%. In Staphylococcus aureus isolates, ophthalmic antibiotic resistance varied from 10.5% for polymyxin B to 66.7% for erythromycin. In Branhamella catarrahalis isolates, ophthalmic antibiotic resistance ranged from 3.4% for levofloxacin to 69% for erythromycin. In Haemophilus influenzae isolates, ophthalmic antibiotic resistance varied from 0.0% for ciprofloxacin and polymyxin B to 42.1% for erythromycin and azithromycin. Conclusion: The most common causative organisms in adult age groups were Branhamella catarrahalis and Staphylococcus aureus. Obviously, there is no single drug that treats these various types of bacteria. Therefore, bacteriological culture and sensitivity in the laboratory to ophthalmic antibiotics should be performed as much as possible. But if laboratory facilities are not available, some generalizations can be made as guidelines for treating conjunctivitis.                     Peer Review History: Received 6 January 2021; Revised 15 February; Accepted 4 March, Available online 15 March 2021 UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.
