Pseudomonas aeruginosa is an environmental pathogen that can cause severe infections in immunocompromised patients. P. aeruginosa infections are typically treated with multiple antibiotics including tobramycin, ciprofloxacin, and meropenem. However, antibiotics do not always entirely clear the bacteria from the infection site, where they may remain virulent. This is because the effective antibiotic concentration and diffusion in vitro may differ from the in vivo environment in patients. Therefore, it is important to understand the effect of non-lethal sub-inhibitory antibiotic concentrations o

The frequent occurrence of multidrug-resistant strains to conventional antimicrobials has led to a clear decline in antibiotic therapies. Therefore, new molecules with different mechanisms of action are extremely necessary. Due to their unique properties, antimicrobial peptides (AMPs) represent a valid alternative to conventional antibiotics and many of them have been characterized for their activity and cytotoxicity. However, the effects that these peptides cause at concentrations below the minimum growth inhibitory concentration (MIC) have yet to be fully analyzed along with the underlying m

Bacteria readily acquire resistance to traditional antibiotics, resulting in pan-resistant strains with no available treatment. Antimicrobial resistance is a global challenge and without the development of effective antimicrobials, the foundation of modern medicine is at risk.

Pseudomonas aeruginosa is an opportunistic pathogen associated with a variety of life-threatening diseases. Infections caused by P. aeruginosa can be nearly untreatable because of its multidrug-resistance. One of the characteristics of P. aeruginosa that helps it survive in high drug concentrations is its ability to form biofilms–large communities of cells encompassed by extracellular polymeric substances that defend against many antibiotics. In fact, sub-minimum inhibitory concentrations of antibiotics stimulate biofilm production. This project aims to identify genes associated with biofilm i

AbstractThe emergence of multidrug resistance in bacteria due to overuse of antibiotics is becoming an important health concern in recent years, which requires development of novel alternatives to fight against these bacteria. Essential oils (EOs) are secondary metabolites that have different components and chemical compositions which may provide promising solution to the problem of rising number of drug resistant bacteria, as they can effectively kill bacteria. Here, in this study our aim is to determine the efficacy of lemongrass, rosemary, clary sage, geranium and tea tree essential oil against Pseudomonas aeruginosa, using agar well diffusion method. The minimum inhibitory concentration (MIC) of these EOs were also determined. The chemical composition of these essential oils were known by gas chromatography-mass spectrometry (GC-MS) analysis. It was revealed in this study that most of the essential oils show antimicrobial property against the test bacterium. The MIC of lemongrass is 0.25% (v/v), rosemary is 1% (v/v), clary sage is 2% (v/v), geranium is 0.5% (v/v) and for tea tree oil is 1% (v/v). We can infer from this data that lemongrass, rosemary, clary sage, geranium and tree oil can be utilized to treat infections caused by Pseudomonas aeruginosa, which is a gram-negative bacterium.

AbstractThe management of infertile men with varicocele is highly debated. Varicocele repair (VR) can be either surgical (varicolectomy) or through angiographic embolization. Surgical repair of varicocele includes open non-microsurgical techniques whether inguinal (Ivanissevich) or high retroperitoneal ligation (Palomo), open microsurgical techniques (inguinal or sub-inguinal) or laparoscopic. The accumulating evidence suggests that VR can improve conventional sperm parameters (sperm concentration, motility, and morphology), seminal oxidative stress, sperm DNA fragmentation, and serum testosterone concentrations.Treatment of cryptorchism is based on surgical correction. The surgical approach for palpable undescended testis is inguinal orchidopexy with eventual repair of concomitant hernia. Scrotal surgical approach is a viable alternative. For nonpalpable undescended testis, surgical approach can be open or laparoscopic, in one or two stages and possibly with spermatic vessel transection. In some cases, orchiectomy is required (testis abdominal localization, impossibility of mobilization or high neoplastic risk).Male accessory gland infections, including infection and/or inflammation of accessory glands (prostate, seminal vesicles, and Cowper’s glands), and male genital tract infections are characterized by the presence of an elevated number of leukocytes and/or pathogens in semen, together with inflammatory signs. Management is based on different antibiotic therapies.

Abstract Summary The disturbed physiology of critical illness considerably impacts blood and tissue concentrations of antimicrobials. In addition, the antimicrobials themselves vary enormously in chemical structure (and therefore charge, solubility, hydrophilicity, etc.), adding yet more complexity to effective and correct calculation of appropriate dose and interval timing. Examples here include on the one hand increased concentrations of hydrophilic beta-lactam antibiotics secondary to poor renal function and/or acute kidney injury, and on the other decreased antibiotic concentrations from increased volumes of distribution, decreased protein binding, and (sometimes artificially augmented by filtration or haemodialysis) renal clearance. Lipophilic antibiotics such as macrolides are less affected by physiological changes—although issues such as obesity influence dosing for optimal outcomes. Some antibiotics also have a narrow efficacy range and therapeutic index. Accordingly, aminoglycosides work best when used in high, once-daily dosing strategies with mandatory therapeutic drug monitoring. On the other hand, beta-lactam antimicrobials often have very short half-lives and are either bactericidal or entirely ineffective when only just below therapeutic concentrations. With such drugs, the most important pharmacodynamic parameter is therefore a ‘time above minimal inhibitory concentration’ optimized with shorter administration regimens, extended or even continuous infusions. None of these considerations should absolve treating physicians from deciding whether individual cases of infection are not better treated by removing the source of infection, as antibiotics alone cannot be expected to deal with large, undrained infected collections for instance.

Ceftiofur is a broad-spectrum cephalosporin, effective against Gram-positive and Gram-negative pathogens. This antibiotic works by inhibiting the synthesis of the bacterial cell wall. Antibiotics, used in both human and veterinary medicine, are drugs of concern when found in the environment. This is due to the fact that, even at low concentrations, prolonged exposure to these residues can lead to the emergence of resistant bacteria, compromising human health and environmental balance. Direct or indirect contact, whether through the food chain, water resources or animal excreta, represent the main routes of contamination. In the present study, in silico methodologies were employed to predict the molecular properties of the antibiotic Ceftiofur. The in silico environmental toxicology study showed that Ceftiofur is not toxic to bees, but is toxic to fish and crustaceans, and its chemical structure does not degrade in the environment. ADME in silico analysis indicated that the antibiotic does not present a favorable prediction for oral bioavailability, due to violations of the Lipinski criteria and has a moderate intestinal absorption rate and absence of permeability across the blood-brain barrier. In addition, the in silico pharmacokinetic study revealed that Ceftiofur has no inhibitory capacity on any of the five hepatic isoenzymes of cytochrome P450 complex (CYP450). The human in silico toxicology study showed promising results, demonstrating that the antibiotic is non-toxic (non-mutagenic) in the AMES test, has no carcinogenic properties, and is classified in category IV for acute oral toxicity, indicating low toxicity.

The anaerobic ammonium oxidation (anammox) process has been recognized as an efficient nitrogen removal technology. Anammox processes are gaining attention owing to their advantages over the conventional biological nitrogen removal processes. Anammox bacteria are susceptible to various wastewater pollutants, which limits the extensive application of the anammox process worldwide. In general, low-concentration pollutants lead to the promotion of the anammox activity, while high-concentration pollutants show inhibitory effects. Moreover, mainstream anammox processes face a variety of challenges that limit their stable operation, such as difficulty in the out-selection of nitrite-oxidizing bacteria, high organic carbon to nitrogen (C/N) ratio, retention of anammox bacteria, and the influence of high concentrations of ammonia and nitrite compounds. Efficient strategies are necessary to manage high carbon to nitrogen ratios, improve performance in low-intensity wastewater, and retain anammox bacteria. This chapter systemically summarizes the recent advances in the inhibition, mechanism involved and recovery process of conventional and emerging pollutants in the anammox process, such as organics, metals, antibiotics and nanoparticles. The key elements in the operation, and maintenance of mainstream anammox processes in full-scale wastewater treatment plants have also been demonstrated. Moreover, for improving the process performance, the primary influencing factors affecting the anammox process have been identified and discussed in this chapter. Taken together, this chapter effectively illustrates the critical perspective on the challenges and opportunities associated with mainstream anammox processes, which will provide an in-depth understanding for researchers and engineers working in this field.

This chapter tries to describe the most important plant extracts and their bioactive compounds which determine the antibiotic activity. Pharmacological assays performed for each plant extract are presented, including the minimum inhibitory concentration (MIC) as the most used experimental method to determine antimicrobial activity. Also, the effective associations between classic antibiotics and plant extracts with antibacterial are presented. The mechanisms of action are deeply explained to the extent that they are known and discovered by in vitro and in vivo studies. Plant-derived compounds have different mechanism of action as antibiotics. They can have other target sites than traditional antimicrobials and subsequently having different mechanisms of action against microbes. Ultimately, this chapter tries to be an invitation to use plant extract as an alternative to chemical, synthetic antibiotics, or used complementary, synergistic for better therapeutically results.

In the extensive domain of “biotechnology and drug development for targeting human diseases”, essential oils have long been revered for their therapeutic potential. Among these, farnesol and farnesene stand out due to their pharmacological attributes. As the challenge of antibiotic resistance intensifies, the scientific community is increasingly exploring the potential of these traditional remedies. Using the KirbyBauer agar diffusion method, a qualitative assessment was conducted on two grampositive and two gram-negative bacterial strains. The broth microdilution technique further determined the Minimum Inhibitory Concentration (MIC), Minimum Bactericidal Concentration (MBC), and the sensitizing impacts of these compounds. Both farnesol and farnesene exhibited antibacterial efficacy against all evaluated strains. Their synergistic potential was highlighted when combined with clavulanic acid, cefuroxime, and cefepime. Among these combinations, farnesene paired with cefepime showed pronounced efficacy against Escherichia coli 82 MR, with an MIC of 0.47 μg/mL. In contrast, in the investigation of Staphylococcus aureus 23MR, it was observed that this particular strain exhibited an increased sensitivity when exposed to combinations containing farnesol. Notably, the Minimum Inhibitory Concentration (MIC) was determined to be 0.03 µg/mL in the presence of both antibiotic agents. To gain deeper molecular insights, docking experiments were performed with the βlactamases of E. coli and S. aureus, focusing on the most effective combinations. All tested compounds—cefuroxime, cefepime, farnesene, and farnesol—acted as noncompetitive inhibitors, suggesting their potential mechanisms of action.

Annotation:
Small intestinal bacterial overgrowth can be defined as the presence of excessive bacteria in the small intestine which can interfere with digestion and absorption. Predisposing causes include sustained hypochlorhydria induced by proton pump inhibitors, small intestinal dysmotility and stasis due to anatomical or motor abnormalities, and reduced antibacterial activity as seen in immunological deficiency and chronic pancreatitis. Presentation is predominantly from consequences of malabsorption, including gastrointestinal symptoms (e.g. diarrhoea or steatorrhoea) and features of specific nutrient malabsorption (e.g. osteoporosis, anaemia, neuropathy, and night blindness). Definitive diagnosis is difficult, requiring a properly collected and appropriately cultured aspirate from the proximal small intestine revealing a total concentration of a mixed growth of bacteria generally greater than 10<sup>5</sup> organisms/ml. Alternative investigations frequently used include glucose/lactulose breath tests or either the <sup>13</sup>C- or <sup>14</sup>C-xylose breath test, with elevated levels of <sup>13</sup>CO<sub>2</sub> or <sup>14</sup>CO<sub>2</sub> found in the breath. There may be low levels of cobalamin (metabolized by Gram-negative anaerobes), increased serum folate (synthesized by overgrowth flora), and increased urinary indicans (intraluminal product of bacterial tryptophan metabolism). Aside from treatment of any nutritional deficiencies, specific treatment is with an antimicrobial that is effective against both aerobic and anaerobic enteric bacteria (e.g. doxycycline, amoxicillin–clavulanic acid, rifaximin, or ciprofloxacin), which can be administered in rotation to reduce antibiotic resistance. Where possible and appropriate, correction of any underlying cause should also be performed.

Staphylococcus aureus is an opportunistic pathogen that lives on surfaces and skin and can cause serious infections once inside the body. While antibiotics effectively kill bacteria, there are a growing number of infections with antibiotic-resistant strains. Antimicrobial peptides (AMPs) are part of the innate immune system and can eliminate pathogens including bacteria, fungi, and viruses, and are a promising alternative to antibiotics. Although studies have reported that AMP-functionalized hydrogels can prevent bacterial adhesion and biofilm formation, these materials generally consist of on

Annotation:
Antimicrobial resistance is one of the most severe threats to global public health in this century. Photodynamic Inactivation (PDI) is an alternative to antibiotic therapy, a standard treatment for infections because the combination of a photosensitizer with light leads to the production of reactive oxygen species that promote eliminating undesirable cells without bacterial selection and with few side effects for the patient. This work investigates whether PDI can restore bacterial sensitivity to antibiotics. PDI protocols using curcumin and light at 450 nm are applied at regular intervals and
