This pathogen often causes fatal foodborne diseases in humans and animals. In recent years, new treatment strategies for bacterial infections have been studied. Bacteriophages might be used as an alternative strategy for battling against bacterial diseases. \u0000Methods: A novel SP-T1 phage was isolated, and its lytic activity against Salmonella Enteritidis strains and other enteric bacterial species was evaluated. In addition to its kinetic and genetic characteristics, it is in vivo cytotoxicity and ability to inhibit the development of biofilms were investigated. \u0000Results: The gene sequence of the major capsid protein confirmed that the SP-T1 phage belonged to the family Siphoviridae. There was no evidence that phage had a lytic effect on bacteria other than the type of Salmonella used in this investigation. The phage exhibited a short latent period of 15 to 20 min and a burst size of 10 plaque forming unit per infected cell. The phage was resistant to temperatures between 15 and 37 °C and pH levels between 5 and 11. The SP-T1 phage exhibited no adverse effects on EPC cell culture and reduced biofilm formation. \u0000Conclusions: Because of its short latent period, appropriate burst size, ability to inhibit biofilm formation, and sensitivity to various temperatures and pH levels, the phage found in this study would be an excellent candidate for phage therapy. These findings are beneficial for improving the microbiological safety and quality of food and creating efficient bacteriophage-based regulation in the food chain.

Rapid identification of MDR-TB using conventional or novel technologies is crucial for effective treatment. Here we assessed the quantity and quality of DNA extracted from MDR-TB isolates, allowing whole-genome sequencing (WGS). \u0000Methods: This was a retrospective study on MDR-TB isolates from five studies conducted in Zimbabwe between 2011 and 2019. The isolates were stored under ambient 37 oC and -80 oC temperatures, respectively. These isolates were resuscitated and confirmed to be Mycobacterium tuberculosis (MTB). DNA was extracted using the N-Cetyl-N-trimethylammonium-bromide standard protocol. The concentration (A260nm) and purity (A260/280) of the extracted DNA before WGS (concentration ≥20ng/ul) were compared among the different storage conditions on Stata v15. \u0000Results: A total of 85 samples were successfully recovered from 106 retrieved. The overall recovery rate was 80.2%. We found a significant difference (p=0.005) in the concentration of the DNA samples by storage temperatures, with samples stored at -80 oC having the lowest concentration. Similarly, a significant difference (p=0.018) was found in the purity of the DNA (samples within the optimal range of 1.8 ± 0.2) by storage conditions, with 34/39 (87.2%) stored under ambient temperature, 18/20 (90.0%) stored in a 37 oC incubator and 1/4 (25.0%) stored at -80 oC. \u0000Conclusions: The better concentration and purity obtained from samples stored at 37 oC and ambient temperatures provide an impetus that such storage conditions could be used in many resource-limited settings where power supplies are a limitation to long storage conditions.

The miRNA in the RNA-induced silencing complex acts as a guide strand and binds the target mRNA. Subsequently, the gene is silenced either by cleaving the target mRNA or repressing the translation. Since the discovery of the first miRNA three decades ago, more than 2000 human miRNAs have been discovered. It is known to regulate hundreds of genes in various physiological and pathophysiological processes, including the development and function of immunologically essential cells. miR-155 plays a vital role in the function of T helper 1, 17, and T regulatory cells. miR-24 positively regulates the function of T helper 1, 17, and T regulatory cells, whereas miR-23 and 27 have a negative regulatory effect. miR-223 regulates the differentiation of neutrophils and monocytes. The role of miRNAs in bacterial infections came to light in 2006 after discovering miR-163 as a negative regulator of defense response in Arabidopsis thaliana infected with Pseudomonas syringae. During bacterial infection in the host, aberrant expression of several miRNAs was discovered. miR-155 was found to be the most commonly dysregulated miRNA in bacterial infections such as Helicobacter pylori, Staphylococcus aureus, Listeria monocytogenes, Mycobacterium tuberculosis, and Chlamydia trachomatis. Therefore, miRNAs can be utilized as a diagnostic and prognostic tool for bacterial infections.

Phage cocktails have been proposed for broad-spectrum therapeutic effects against such resistant bacteria. However, the effectiveness of non-locally formulated phage cocktails for therapy on Kenyan isolates has yet to be evaluated and is a subject of investigation. This study aimed to determine the in vitro effectiveness of a non-locally made commercial pyophage cocktail on clinical Pseudomonas aeruginosa isolates from Kenya. \u0000Methodology: Forty-nine P. aeruginosa isolates from Kenya were subjected to a pyophage cocktail for efficacy studies using direct spot test (DST) and efficiency of plating (EOP). \u0000Results: The success rate of the cocktail was observed on 16.3% (8/49) isolates only and ineffective on 83.7% (41/49) isolates. Six of the eight isolates that showed cross-reactivity from DST had complete lysis with a faintly hazy background. Five of these six isolates resulted in successful and high phage progeny production in plaquing efficiency (EOP ≥ 0.5). \u0000Conclusion: Non-locally made commercial pyophage cocktail was ineffective against the 83.7% endemic clinical strains of the Kenyan P. aeruginosa isolates, demonstrating the importance of locally derived phage cocktails against endemic and multidrug-resistant isolates.

The presence of biofilms in the water supply protects the organism from the antimicrobial effects of disinfectants leading to the formation of the MDR pathogen pool. Therefore, this study was taken up to determine the prevalence of biofilm formation in the bacteria isolated from the water system of a tertiary health care setup and study the effect of disinfectants on biofilms. \u0000Methods: Thirty-four drinking water samples were collected in sterile glass stopper bottles and transported to the lab. Standard bacteriological procedures identified isolates. Biofilm detection was carried out by the tissue culture plate (TCP) method. The effect of disinfectant (sodium hypochlorite) at various concentrations (0, 0.25, 0.5, 1, 2, and 4 %) on biofilm-producing organism were studied for 30 minutes and analyzed. \u0000Results: The culture positivity was 76.4% (26/34). Twenty samples showed monomicrobial growth, while only six samples showed polymicrobial growth of organisms. The most common organism isolated was Pseudomonas aeruginosa.

A high level of resistance to chlorine compounds was seen in biofilm-producing microorganisms, especially those that produced robust biofilms. \u0000Conclusion: Resistance of biofilms against high levels of chlorine has implications for the delivery of safe drinking water. Drug resistance was seen in these organisms, which can be transmitted from drinking water sources to humans.

Metastatic tuberculous abscesses (tuberculous gummas), uncommon forms of cutaneous TB, typically result from the bacillus spreading hematogenously from the main site of infection to the subcutaneous tissue when the body's cell mediated immunity is compromised and present with one or more non-tender and fluctuant subcutaneous nodules. Case Presentation: A 51-year-old male presented with dry cough of one month duration associated with loss of appetite, easy fatigability and vomiting of ingested matter. He had left armpit and lower back skin swellings of similar duration. Physical findings were remarkable for whitish coat over the dorsal part of the tongue, crepitation over the lower two-third of bilateral posterior chest, and non-tender fluctuant masses over the left axilla and lower back region. Chest X-ray revealed multiple bilateral air space nodules and abdominopelvic U/S showed numerous hypoechoic splenic lesions. Urine lipoarabinomannan and Xpert MTB/RIF (mycobacterium tuberculosis/rifampicin) assay from the axillary skin abscess were positive for MTB. He was started on anti-tuberculous therapy and showed marked improvement after a month of follow up. Conclusion: It is worth considering the uncommon manifestations of tuberculosis including metastatic skin abscesses in the appropriate clinical context, to avoid misdiagnosis and underreporting in high tuberculosis burden countries.
