Background and Objectives: Antibiotic resistance is emerging as a major public health concern. From the ancient time in history, different plants and herbs have been known to have medicinal value. Rhus javanica has been found to show antibacterial activity against pathogenic bacteria. Thus, present study is designed to investigate the prevalence of urinary tract infection causing bacterial pathogens, its antibiogram and effect of Rhus javanica in standard in-vitro condition against multidrug-resistant. Material and Methods: Cross-sectional study was conducted in urinary tract infection suspected patients visiting a clinic in Kalimati, Kathmandu, from July to December 2017. A total of 133 midstream urine samples were collected and cultured in MacConkey agar and Blood agar media and isolates were identified by standard biochemical tests. Antibiotic susceptibility testing was performed according to Clinical and Laboratory Standard Institute (CLSI) guideline. Leaves extract of Rhus javanica was obtained by maceration using 50.0% methanol and susceptibility testing was performed by using cork borer method in Mueller-Hinton agar. Results: Out of total 133 samples, 35.3%showed significant bacterial growth (i.e. 105 cfu/ml) on agar plate. The most predominant organism was Escherichia coli 17.3%, followed by Enterococcus faecalis 6.8%, Klebsiella pneumoniae 3.8%, Pseudomonas aeruginosa 3.0%, Proteus vulgaris 2.3%, and Staphylococcus aureus 2.3%. Out of 47 isolates, 53.2% were Multi Drug Resistant (MDR). Various concentrations of the crude extract used (25, 50, 75 and 100 mg/ml) showed susceptibility to all the bacterial pathogens isolated, with the diameter of zone of inhibition ranging from 12 to 28 mm. Conclusion: Methanolic extract of Rhus javanica showed antibacterial activity against multidrug-resistant isolates of bacterial uropathogens in standard in-vitro condition.

ABSTRACTThe ability to change cell morphology is an advantageous characteristic adopted by multiple pathogenic bacteria in order to evade host immune detection and assault during infection. UropathogenicEscherichia coli(UPEC) exhibits such cellular dynamics and has been shown to transition through a series of distinct morphological phenotypes during a urinary tract infection. Here, we report the first systematic spatio-temporal gene expression analysis of the UPEC transition through these phenotypes by using a flow chamber-basedin vitroinfection model that simulates conditions in the bladder. This analysis revealed a novel association between the cell division genedamXand reversible UPEC filamentation. We demonstrate a lack of reversible bacterial filamentation in adamXdeletion mutantin vitroand absence of a filamentous response by this mutant in a murine model of cystitis. While deletion ofdamXabrogated UPEC filamentation and secondary surface colonization in tissue culture and in mouse infections, transient overexpression ofdamXresulted in reversible UPEC filamentation. In this study, we identify a hitherto-unknowndamX-mediated mechanism underlying UPEC morphotypical switching. Murine infection studies showed that DamX is essential for establishment of a robust urinary tract infection, thus emphasizing its role as a mediator of virulence. Our study demonstrates the value of anin vitromethodology, in which uroepithelium infection is closely simulated, when undertaking targeted investigations that are challenging to perform in animal infection models.IMPORTANCEUrinary tract infections (UTIs) are most often caused by uropathogenicEscherichia coli(UPEC) and account for a considerable health care burden. UPEC exhibits a dynamic lifestyle in the course of infection, in which the bacterium transiently adopts alternative morphologies ranging from rod shaped to coccoid and filamentous, rendering it better at immune evasion and host epithelium adhesion. This penchant for morphotype switching might in large measure account for UPEC’s success as a pathogen. In aiming to uncover genes underlying the phenomenon of UPEC morphotype switching, this study identifiesdamX, a cell division gene, as a mediator of reversible filamentation during UTI. DamX-mediated filamentation represents an additional pathway for bacterial cell shape control, an alternative to SulA-mediated FtsZ sequestration duringE. coliuropathogenesis, and hence represents a potential target for combating UTI.

Drug resistance of bacteria is biggest challenge humanity is going to face in near future. Bacteria are rapidly developing resistant to multiple drugs and there are not many new drugs in pipeline. Infection because of drug resistant organism is a common cause of morbidity and mortality in intensive care unit. If acquisition of drug resistance by microorganism progresses at this rate, that time is not very far when we will be pushed in to preantibiotic era. We need to develop new strategies to combat drug resistant by microorganism. We report a case of highly drug resistant urinary tract infection caused by Klebsiella. This strain was resistant to both Inj. Meropenem and Inj. Amikacin. This case was successfully treated by combination of Inj. Meropenem and Inj. Amikacin and complete resolution of infection was observed.

Tract Infections

Background: A urinary tract infection (UTIs) is a common type of infection caused by bacteria that travel up the urethra to the bladder. Globally, it is reported that 150 million people are diagnosed with a UTI annually, costing the world economy over 6 million US dollars in treatment and work loss. Studies conducted in the in-patients pediatric ward of Muhimbili Hospital in Tanzania and Mulago National Referral Hospital in Uganda between five to ten years reported the prevalence of UTI to be 16.8% and 14.6% respectively. On average at Kam Medical Consult Clinic, patients who turn up in the laboratory are about 20%, and 50% of patients present with recurring UTIs clinically. Therefore,  there is a need to establish and investigate the prevalence of bacterial pathogens associated with UTI and multiple pathogens that are not known. Methodology: The cross-sectional study was carried out at Kam medical consult clinic (KMCC) located in Kafeero zone Mulago II Kawempe division. The study population was adults and children presenting with symptoms of urinary tract infection. 120 Midstream urine Samples were collected from patients presenting clinical signs of UTI. The diagnosis was done through macroscopy dry chemistry, microscopy, and culture. Results Among the sampled population, 33% of males had urinary tract infections while 67% of females had urinary tract infections.  88.5% were outpatients while 11.5 % were in-patients The overall prevalence of UTI among patients was 63.3% with children aged (1-10) having a prevalence of 5.8 %. Conclusion and recommendation: E.coli is an etiological agent causing UTIs in male and female patients presenting UTI at Kam Medical Consult Clinic. Other etiological agents included Klebsiella, Coliform, Enterococcus species, staphylococcus aureus, pseudomonas species, and candida species. There is a need to monitor the profile of etiological bacteria of UTI through culture and sensitivity regularly.

Abstract Urinary tract infection (UTI) caused by bacterial pathogens of the respiratory tract such as Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis is rare and little is known about their characteristics and potential host risk factors. We conducted a retrospective descriptive study on pediatric UTI due to S. pneumoniae, Haemophilus spp., or M. catarrhalis at a tertiary-care pediatric hospital. Pediatric patients with diagnosed UTI between 2002 and 2020 were included. Patient demographics, laboratory data, and microbiological findings were extracted from their electronic medical records and the infectious disease surveillance system. Among 46,332 urine samples, 76 bacteriuria (0.16%) and 22 UTI (0.05%) events due to the targeted species were identified (S. pneumoniae [n=7] and Haemophilus spp. [n=15]). Of the patients, 17 (85%) had underlying urinary tract abnormalities and 13 (60%) had vesicocutaneous fistula. All the UTI episodes caused by S. pneumoniae and Haemophilus spp. occurred after cystostomy. All the patients had satisfactory clinical outcomes.Conclusion: Although S. pneumoniae and Haemophilus spp. are rare causes of UTI in children, they could be the true causative bacteria of UTI even when detected in urine specimens, particularly in the patients with urinary tract abnormalities and vesicocutaneous fistula.
