Kacholi DS. A comprehensive review of antimalarial medicinal plants used by Tanzanians. PHARMACEUTICAL BIOLOGY 2024; 62:133-152. [PMID: 38270178 PMCID: PMC10812860 DOI: 10.1080/13880209.2024.2305453] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Accepted: 01/09/2024] [Indexed: 01/26/2024]
Abstract
CONTEXT Tanzania has rich medicinal plant (MP) resources, and most rural inhabitants rely on traditional healing practices for their primary healthcare needs. However, available research evidence on antimalarial MPs is highly fragmented in the country. OBJECTIVE This systematic review compiles ethnomedicinal research evidence on MPs used by Tanzanians as antimalarials. MATERIALS AND METHODS A systematic web search was conducted using various electronic databases and grey materials to gather relevant information on antimalarial MPs utilized by Tanzanians. The review was per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The data were collected from 25 articles, and MS Excel software was used to analyse relevant ethnobotanical information using descriptive statistics. RESULTS A total of 227 MPs belonging to 67 botanical families and 180 genera were identified. Fabaceae (15.9%) is the most frequently utilized family. The ethnobotanical recipes analysis indicated leaves (40%) and trees (44%) are the preferred MPs part and life form, respectively. Decoctions (67%) are the dominant preparation method of remedies. Of the recorded MPs, 25.9% have been scientifically investigated for antimalarial activities with positive results. However, 74.1% of MPs have no scientific records on antimalarial activities, but they could be potential sources of remedies. CONCLUSIONS The study discloses a wealth of antimalarial MPs possessed by Tanzanians and suggests a need for research to authenticate the healing potential of antimalarial compounds from the unstudied MPs. Additionally, it indicates that some of the presented MPs are potential sources for developing safe, effective and affordable antimalarial drugs.

Rapid discrimination methods for clinical and environmental strains of Aeromonas hydrophila and A. veronii biovar sobria using the N-terminal sequence of the flaA gene and investigation of antimicrobial resistance. Lett Appl Microbiol 2024; 77:ovae052. [PMID: 38830808 DOI: 10.1093/lambio/ovae052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 05/27/2024] [Accepted: 06/01/2024] [Indexed: 06/05/2024]
Abstract
Although the genus Aeromonas inhabits the natural environment, it has also been isolated from hospital patient specimens as a causative agent of Aeromonas infections. However, it is not known whether clinical strains live in the natural environment, and if these strains have acquired antimicrobial resistance. In this study, we performed the typing of flagellin A gene (flaA) of clinical and environmental strains of Aeromonas hydrophila and A. veronii biovar sobria using Polymerase Chain Reaction (PCR) assay with newly designed primers. Detection rates of the clinical and environmental flaA types of A. hydrophila were 66.7% and 88.2%, and the corresponding rates for A. veronii biovar sobria were 66.7% and 90.9%. The PCR assays could significantly discriminate between clinical and environmental strains of both species in approximately 4 h. Also, among the 63 clinical Aeromonas strains used, only one extended-spectrum β-lactamase-producing bacteria, no plasmid-mediated quinolone resistance bacteria, and only four multidrug-resistant bacteria were detected. Therefore, the PCR assays could be useful for the rapid diagnosis of these Aeromonas infections and the monitoring of clinical strain invasion into water-related facilities and environments. Also, the frequency of drug-resistant Aeromonas in clinical isolates from Okinawa Prefecture, Japan, appeared to be low.

Antimicrobial susceptibility patterns of urinary tract infections causing bacterial isolates and associated risk factors among HIV patients in Tigray, Northern Ethiopia. BMC Microbiol 2024; 24:148. [PMID: 38678188 PMCID: PMC11055276 DOI: 10.1186/s12866-024-03297-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Accepted: 04/07/2024] [Indexed: 04/29/2024] Open
Abstract
BACKGROUND Urinary tract infections, a prevalent global infectious disease, are clinical issues not well studied in HIV-positive individuals. UTIs have become a global drug resistance issue, but the prevalence and antibiotic susceptibility patterns of UTI-causing bacteria among HIV patients in Tigray, Ethiopia, are poorly understood. This study aims to identify the prevalence of UTI-causing bacteria, their antibiotic susceptibility patterns, and associated risk factors in HIV patients attending ART clinics at Mekelle General Hospital and Ayder Comprehensive Specialized Hospital in Tigray, Northern Ethiopia. METHOD Clean-catch midstream urine samples (10-15 mL) were collected from HIV patients who are attending ART clinics at Mekelle General Hospital and Ayder Comprehensive Specialized Hospital. Samples were analyzed based on standard microbiological protocols using cysteine-lactose electrolyte deficient (CLED) agar. Pure colonies of bacterial isolates were obtained by sub-culturing into Mac-Conkey, Manitol Salt agar and blood agar plates. The bacterial isolates were then identified using macroscopic, microscopic, biochemical, and Gram staining methods. Gram-negative bacteria were identified using biochemical tests like triple sugar iron agar, Simon's citrate agar, lysine iron agar, urea, motility test, and indol test, whereas Gram-positive isolates were identified using catalase and coagulase tests. The Kirby-Bauer disk diffusion technique was used to analyze the antimicrobial susceptibility pattern of bacterial isolates. Data was analyzed using SPSS version 25.0. RESULTS Among the 224 patients, 28 (12.5%) of them had been infected by UTIs-causing bacteria. E. coli was the dominant bacterium (16 (57%)) followed by K. pneumoniae (4 (14%)), and S. aureus (3 (11%)). Of the total bacterial isolates, 22 (78.6%) of them developed multi-drug resistance. All Gram-positive (100%) and 75% of Gram-negative bacterial isolates were found to be resistant to two or more drugs. Patients with a history of UTIs, and with CD4 count < 200 cells/ mm3, were more likely to have significant bacteriuria. Compared to male patients, female patients were more affected by the UTIs-causing bacteria. More than 93% of the UTIs-causing bacterial isolates were susceptible to nitrofurantoin, ceftriaxone, ciprofloxacin, and gentamycin; whereas they are highly resistant to ampicillin (96%), cotrimoxazole (82%) and tetracycline (71%). CONCLUSIONS Most of the bacterial isolates were highly resistant to ampicillin, cotrimoxazole, and tetracycline. Female patients were more affected by the UTIs causing bacteria. The highest prevalence (12.5%) of UTIs in HIV patients needs special attention for better management and monitoring. Previous UTI history and immune suppression are predictors of UTIs, highlighting the need for intervention measures involving molecular studies to identify resistant bacteria genes and promote patient immune reconstitution.

Abstract
BACKGROUND Τhe adherence of p-fimbriated Escherichia coli (E. coli) to urothelial cells leading to recurrent urinary tract infections (rUTIs) may be prevented by proanthocyanidins (PACs) contained in American cranberries. PURPOSE The purpose of this clinical trial was to assess the clinical utility of prophylactic use of high-dose PACs daily in women with a history of rUTIs. MATERIALS AND METHODS 172 adult women with a history of rUTIs, defined as ≥ 2 within a 6-month period or ≥ 3 within a 12-month period were enrolled and randomized in two groups to receive either Cysticlean™ 240 mg or placebo for a 12-month period. Urine samples, vaginal and rectal swabs were collected at initial and quarterly study visits. The primary study endpoints were the number of urinary tract infections (UTIs) and changes in Quality of Life (QoL), assessed by the 36-Item Short Form Survey (SF-36) questionnaire. RESULTS 160 adult women of median age 40 years old (range 19-82) were finally analyzed in this randomized, placebo-controlled, double-blinded clinical trial. In response to intervention, the number of UTIs was significantly lower (Incidence rate ratio IRR 0.49, p < 0.001) and QoL was slightly improved. The numbers of E. coli isolates detected in vaginal (IRR 0.71, p value < 0.001) and in rectal swabs (IRR 0.87, p value < 0.001) were also significantly decreased. No adverse events were reported. CONCLUSION The daily use of Cysticlean™ 240 mg was associated with a reduction of UTIs and a prolongation of UTI-free survival compared to placebo treatment, supporting its use as prophylaxis in this patient population.

Antibiotic Resistance Profiling and Phylogenicity of Uropathogenic Bacteria Isolated from Patients with Urinary Tract Infections. Antibiotics (Basel) 2023; 12:1508. [PMID: 37887209 PMCID: PMC10603882 DOI: 10.3390/antibiotics12101508] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 09/16/2023] [Accepted: 09/20/2023] [Indexed: 10/28/2023] Open
Abstract
Urinary tract infections (UTIs) are healthcare problems that commonly involve bacterial and, in some rare instances, fungal or viral infections. The irrational prescription and use of antibiotics in UTI treatment have led to an increase in antibiotic resistance. Urine samples (145) were collected from male and female patients from Lower Dir, Khyber Pakhtunkhwa (KP), Pakistan. Biochemical analyses were carried out to identify uropathogens. Molecular analysis for the identification of 16S ribosomal RNA in samples was performed via Sanger sequencing. Evolutionary linkage was determined using Molecular Evolutionary Genetics Analysis-7 (MEGA-7). The study observed significant growth in 52% of the samples (83/145). Gram-negative bacteria were identified in 85.5% of samples, while Gram-positive bacteria were reported in 14.5%. The UTI prevalence was 67.5% in females and 32.5% in males. The most prevalent uropathogenic bacteria were Klebsiella pneumoniae (39.7%, 33/83), followed by Escherichia coli (27.7%, 23/83), Pseudomonas aeruginosa (10.8%, 9/83), Staphylococcus aureus (9.6%, 8/83), Proteus mirabilis (7.2%, 6/83) and Staphylococcus saprophyticus (4.8%, 4/83). Phylogenetic analysis was performed using the neighbor-joining method, further confirming the relation of the isolates in our study with previously reported uropathogenic isolates. Antibiotic susceptibility tests identified K. pneumonia as being sensitive to imipenem (100%) and fosfomycin (78.7%) and resistant to cefuroxime (100%) and ciprofloxacin (94%). Similarly, E. coli showed high susceptibility to imipenem (100%), fosfomycin (78.2%) and nitrofurantoin (78.2%), and resistance to ciprofloxacin (100%) and cefuroxime (100%). Imipenem was identified as the most effective antibiotic, while cefuroxime and ciprofloxacin were the least. The phylogenetic tree analysis indicated that K. pneumoniae, E. coli, P. aeruginosa, S. aureus and P. mirabilis clustered with each other and the reference sequences, indicating high similarity (based on 16S rRNA sequencing). It can be concluded that genetically varied uropathogenic organisms are commonly present within the KP population. Our findings demonstrate the need to optimize antibiotic use in treating UTIs and the prevention of antibiotic resistance in the KP population.

Abstract
Bacterial urinary tract infections (UTI) commonly occur in children; if left untreated, they may result in severe consequences such as uro-sepsis and renal damage. This study aimed to determine the bacterial profile, antimicrobial susceptibility patterns and associated factors among paediatric patients suspected of urinary tract infections in Arba Minch General Hospital (AMGH). An institution-based cross-sectional study was conducted from 01 October 2020 to 31 January 2021. A convenient sampling technique was used to recruit the participants; data were collected using a pre-tested questionnaire. To quantify the bacteria (as per the Kass count, >105CFU/ml), midstream urine samples were streaked onto bacteriological media. Isolates were identified by following standard procedures. The antibiotic susceptibility test was performed as per the Kirby-Bauer disc diffusion technique. Data were analyzed using SPSS software. Out of the 246 children included, 38 (15.4%) were found to be positive for significant bacteriuria. Isolates of Escherichia coli, 9/38 (23.7%), and Staphylococcus aureus, 9/38 (23.7%), were the most predominant. The majority of Gram-negative bacterial (GNB) isolates showed resistance towards amoxicillin-clavulanate (89.5%), ampicillin (84.6%), and ceftazidime (81%). Likewise, 76.9 and 76.5% of Gram-positive bacteria (GPB), respectively, had shown resistance towards co-trimoxazole and tetracycline. Multi-drug and extensively drug resistance were detected respectively in the case of 68.4 and 15.8% of the total isolates; ESBL production was found in 57.1% of GNB, whereas 55.6% of S. aureus were methicillin-resistant S. aureus (MRSA). The process of un-circumcision was significantly associated with UTI [(adjusted odds ratio= 3.578; 95% confidence interval: 1.263 - 10.13; p=0.016)].

Abstract
Background Globally, urinary tract infections (UTIs) are a common health issue among women. Investigating risk factors associated with culture-proven UTIs and the antimicrobial resistance profile of uropathogens would provide insight into planning prevention and control measures. Objective To identify the risk factors associated with UTIs among sexually active women and determine antimicrobial susceptibility patterns of uropathogenic bacterial isolates. Methods A case-control study was conducted from February to June 2021, involving 296 women (62 case group and 234 control group in a ratio of 4:1). Cases were defined as culture-confirmed UTIs, and controls were non-UTIs. A semi-structured questionnaire was used to collect demographic, clinical, and behavioral data. The antimicrobial susceptibility test was done by the Kirby-Bauer disc diffusion method. The data were analyzed using SPSS version 25. Bivariable and multivariable logistic regressions were used to identify risk factors, and the strength of association was measured by adjusted odds ratios and a 95% confidence interval used at P-values < 0.05. Results The results revealed that recent coitus and frequency of coitus more than three times per week (P=0.001) were independent predictors of UTIs. Swabbing from back to front, a history of UTI and a delay in voiding were also independent predictors (P < 0.05). On the other hand, a daily water intake of 1 to 2 litres reduced the risk of UTI (P= 0.001). The predominant uropathogenic isolate was Escherichia coli (35.48%). Over 60% of isolates were resistant to cotrimoxazole, penicillin, cephalosporin, and fluoroquinolones. The most effective antibiotics included piperacillin-tazobactam, aminoglycosides, carbapenem, and nitrofurantoin. 85% and 50% of isolates were MDR and ESBL producers, respectively. Conclusion The finding indicates the importance of public intervention targeting the identified risk factors and the resistance phenotype to reduce the burden of UTIs with antimicrobial resistance in the study area.

Abstract
OBJECTIVE Urinary tract infection has catastrophic health outcome among diabetes mellitus patients. This study was conducted to investigate prevalence of bacterial uropathogens, their antibiogram, and associated factors among diabetes mellitus patients in Kombolcha town. METHOD Cross-sectional study was done from February to April 2020. A total of 282 study participants were involved and simple random technique was applied for enrollment of subjects. Well-constructed and pre-tested questionnaire was utilized to collect the data. Five to ten milliliters of mid-stream urine specimen was collected for microbiological data. Each sample was inoculated into cystine lactose electrolyte deficient medium, incubated overnight in aerobic atmosphere at 37°C for 24 h and finally biochemical tests were carried out. According to Kirby-Bauer disk diffusion method, the antimicrobial susceptibilities pattern of the bacteria was performed on Mueller-Hinton Agar. The data were analyzed with Statistical Package for Social Sciences version 23. Descriptive statistics, bi-variable, and multivariable logistic regression analyses were performed. For statistical significance association, p value ⩽ 0.05 with a 95% confidence interval was considered. RESULTS The general prevalence of urinary tract infection among study participants was 20.2% (57/282). Being female and having merchant occupation had a statistically significant association. Gram-negative bacteria accounted for 70.2% (40/57) and the leading isolate was Escherichia coli, followed by Klebsiella pneumoniae and Coagulase negative Staphylococcus. About 57.5% gram-negative and 35.3% gram-positive bacteria showed multidrug resistance. CONCLUSION The general prevalence of significant bacteriuria was found to be consistent with similar studies conducted in different areas. The higher multidrug resistance rate was observed for the isolated bacteria. Health-care professionals should give due attention and follow rational antibiotic prescription practices to treat these infections.

Data were entered and analyzed using SPSS version 21. Descriptive and Logistic regression analysis was applied to determine the determinants of Campylobacter infection. P-value < 0.05 was considered statistically significant.
Results
A total of 235 under-five children were enrolled in this study with a 100% response rate. Of these 130 (55.3%) and 105(44.7%) were males and females respectively with the age range of 2 months to 60 months with the mean age of 25 months. The majority of the 150 (63.2%) were rural residents. Of 235 under-fives with acute watery diarrhea, 16 (6.8%) patients were found to have Campylobacter infection with (95% CI, 3.8–10.2%). Consumption of pasteurized milk (AOR: 0.12; 95% CI 0.02–0.75, P<0.05), presence of domestic animals like cats, hens, and cows (AOR: 0.09: 95% CI 0.01–0.67, P<0.05), absence of handwashing practice before food preparation (AOR: 3.63, 95% CI 1.15–11.46, P<0.05) showed significant association with campylobacter infection.
The antimicrobial susceptibility patterns of the isolated bacteria were 100% sensitivity to Azithromycin, Chloramphenicol, and Gentamicin, however; it was 100% resistant to Cephalothin. The associations of socio-demographic, environmental, and behavioral factors were compared and consumption of unpasteurized milk, the presence of domestic animal like the cat was significantly associated.
Conclusion
Campylobacter infection showed a comparatively low prevalence in under-fives with acute watery diarrhea. In this study contact with cats, consumption of unpasteurized milk were associated with Campylobacter infection. The treatment approach of Campylobacter infection must consider the sensitivity profile of antibiotics as indicated in the study. We, therefore, recommend further studies to determine the species responsible for Campylobacter infection with other co-morbidities and the susceptibility pattern for each species to indicate appropriate antibiotic therapy.
