Abstract
Background Antibiotic resistance is a growing global health threat worldwide and especially in developing countries. Irrational antibiotic prescription as well as lack of the requisite knowledge and awareness of proper antibiotic use are major drivers of antibiotic resistance. In Kenya, although the Ministry of Health has developed antibiotic use guidelines, these guidelines are not widely followed. Antibiotic prescription is, therefore, hugely at the discretion of the clinician. It is thus necessary to understand the knowledge, attitude, and practices (KAP) of antibiotic prescription among medical practitioners in the country. This study aimed to evaluate the knowledge, attitude, and practices (KAP) among antibiotic prescribers in three counties (Kiambu, Nakuru, and Bungoma) in Kenya. Methods This was a cross-sectional study using a self-administered questionnaire. Simple descriptive statistics were used to generate frequencies, percentages, and proportions. Where necessary, univariate analyses such as Pearson’s chi-square were performed to compare proportions for statistical significance. Results From the three counties, 240 respondents recorded their responses: 30% from Kiambu, 34.6% from Nakuru, and 35.4% from Bungoma. The respondents included 19 (7.9%) consultants, 66 (27.4%) medical officers, 135 (56.3%) clinical officers and 20 (8.3%) pharmacists. Of all respondents, more than 90% agreed or strongly agreed that antibiotic resistance (ABR) is a catastrophe worldwide and in Kenya. However, the proportion of the respondents who either agreed or strongly agreed (71.6%) that antibiotic resistance is a problem in their respective health facilities was significantly lower (ρ=0.013). Conclusion This study revealed that most medical practitioners were aware and knowledgeable about antibiotic resistance. However, there was a disconnect with mitigation measures such as active antibiotic stewardship and laboratory analyses to support judicious prescription. There is, therefore, a need for continuous education and stewardship interventions.

Abstract
AbstractObjectives:To evaluate the emergence of resistance ofPseudomonas aeruginosaandAcinetobacterspecies to imipenem, ciprofloxacin, or both after the use of these drugs and to compare resistant with susceptible isolates by molecular typing.Design:Cohort study.Setting:Burn intensive care unit (ICU) with 4 beds in a tertiary-care university hospital.Methods:During 16 months, surveillance cultures were performed for all patients admitted to the ICU. Demographic information was obtained for each patient. Molecular typing was done by pulsed-field gel electrophoresis using restriction enzymes for 71 isolates ofP. aeruginosaandAcinetobacterspecies.Results:Thirty-four patients were admitted and 22 were colonized by susceptibleP. aeruginosaorAcinetobacterspecies before they used the antimicrobials. Nine (41%) of these patients had a resistant isolate after antimicrobial use: 5 had used imipenem alone, 1 had used ciprofloxacin, and 3 had used both drugs. The interval between isolation of the susceptible and resistant isolates ranged from 4 to 25 days, but was 10 or more days for 6 patients. Molecular typing revealed that susceptible and resistant isolates from each patient were different and that although there were no predominant clones among susceptible isolates, there was a predominant clone among resistant isolatesof P. aeruginosaandof Acinetobacter.Conclusions:Resistance was not due to the acquisition of resistance mechanisms by a previously susceptible strain, but rather to cross-transmission. Although various measures involving antimicrobial use have received great attention, it would seem that practices to prevent cross-transmission are more important in controlling resistance.

Abstract
Quinoxaline derivatives are an important class of heterocycle compounds, where N replaces some carbon atoms in the ring of naphthalene. Its molecular formula is C8H6N2, formed by the fusion of two aromatic rings, benzene and pyrazine. It is rare in natural state, but their synthesis is easy to perform. In this review the State of the Art will be presented, which includes a summary of the progress made over the past years in the knowledge of the structure and mechanism of the quinoxaline and quinoxaline derivatives, associated medical and biomedical value as well as industrial value. Modifying quinoxaline structure it is possible to obtain a wide variety of biomedical applications, namely antimicrobial activities and chronic and metabolic diseases treatment.

Abstract
BACKGROUND In this study, we investigated the ability of protamine sulfate, at sub-bactericidal dosing, to interfere with the in vivo virulence of Pseudomonas aeruginosa (PAO1) during burn wound infection. MATERIALS AND METHODS The study was conducted using the murine model of thermal injury. Preliminary experiments determined a protocol for administration of protamine sulfate that had no in vivo bactericidal effects. Based on this, the effect of local injection of protamine sulfate on the in vivo virulence of PAO1 was assessed using these parameters: (1) the percent mortality among PAO1-infected, thermally injured mice; (2) the local proliferation and spread of PAO1 within the infected burned tissue; (3) the systemic spread of PAO1 within thermally injured/infected mice; and (4) the local cytokine response elicited by PAO1 thermally injured/infected mice. RESULTS Injection of protamine sulfate into the thermally injured tissue of PAO1-infected/thermally injured mice significantly decreased the percent mortality and inhibited the systemic dissemination of PAO1 microorganisms to the liver and spleen. It had no effect, however, on the ability of the bacteria to proliferate and spread within the thermally injured tissue. It also was determined that protamine sulfate was ineffective at preventing mouse death at the dose administered if injected intramuscularly instead of directly into burned tissue. Protamine sulfate reduced the expression of the proinflammatory cytokines IL-6 and LIF in the injured/infected tissue. Heparan sulfate given in conjunction with protamine sulfate returned mortality levels to those of untreated mice. CONCLUSIONS Our results suggest that: (1) local injection of sub-bactericidal doses of protamine sulfate reduces the virulence of P. aeruginosa; (2) this effect is due to interference with the systemic rather than local spread of P. aeruginosa; and (3) local application of protamine sulfate may have potential as supportive therapy for prevention of systemic P. aeruginosa infection in severely burned patients.

Abstract
The discovery and eventual introduction of anti-microbial agents to clinical medicine was one of the greatest medical triumphs of the twentieth century that revolutionized the treatment of bacterial diseases. However, the gradual emergence of populations of antibiotic-resistant bacteria resulting from use, misuse and outright abuse of antibiotics has today become a major public health problem of global proportions. This review paper examines the origins and molecular epidemiology of resistance genes, global picture of antibacterial resistance, factors that favour its spread, strategies for its control, problems of control and the consequences of failure to contain antibiotic resistance in bacteria.

Abstract
BACKGROUND The opportunistic pathogen Pseudomonas aeruginosa causes severe infections in immunocompromised hosts. Among P. aeruginosa-infected burn patients, mortality may reach as high as 50%. Due to their immunocompromised status, burn patients may benefit from passive immunotherapy against infection. As a potential multivalent immunoglobulin therapy, specific polyclonal antibodies against four P. aeruginosa virulence factors, including exotoxin A (ETA), were prepared. MATERIALS AND METHODS AND RESULTS In this study, we analyzed the ability of ETA antibody (ETA-Ab) to neutralize the in vivo effects of ETA. Adult mice injected with purified ETA suffered 100% mortality. The cytosolic DNA of their hepatocytes was fragmented, indicating ETA induction of apoptosis. In addition, multiprobe RNase protection assays showed that ETA upregulates the expression of the genes for proinflammatory cytokines as well as apoptosis genes in the livers of ETA-injected mice. Treatment with ETA-Ab prior to ETA injection prevented mortality, ETA-induced hepatocyte DNA fragmentation, and upregulation of the cytokine and apoptosis-related genes. The role of ETA during P. aeruginosa infection of the burn wound was examined by determining the in vivo virulence of P. aeruginosa PA103 and its isogenic, ETA-deficient mutant PA103Omega::toxA using the thermally injured mouse model. The lethality, local spread, and systemic spread of PA103Omega::toxA were significantly reduced compared to PA103. CONCLUSION These results suggest that (1) ETA induces apoptosis in hepatocytes, (2) specific cytokines are produced in response to ETA, (3) ETA-Ab neutralizes these effects, and (4) ETA contributes to the spread of P. aeruginosa during burn wound infection.
