The purpose of this non-random retrospective cohort study was to evaluate the impact of prophylactic antibiotic on early outcomes including postoperative pain, swelling, bleeding and cyanosis in patients undergoing dental implant placement before prosthetic loading. Seventy-five patients (45 males, 30 females) whose dental implant placement were completed, included to the study. Patients used prophylactic antibiotics were defined as the experimental group and those who did not, were defined as the control group. The experimental group received 2 g amoxicillin + clavulanic acid 1 h preoperatively and 1 g amoxicillin + clavulanic acid twice a day for 5 days postoperatively while the control group had received no prophylactic antibiotic therapy perioperatively. Data on pain, swelling, bleeding, cyanosis, flap dehiscence, suppuration and implant failure were analyzed on postoperative days 2, 7, and 14 and week 12. No statistically significant difference was detected between the two groups with regard to pain and swelling on postoperative days 2, 7, and 14 and week 12 ( p >0.05), while the severity of pain and swelling were greater on day 2 compared to day 7 and 14 and week 12 in both groups ( p =0.001 and p <0.05, respectively). Similarly, no significant difference was found between the two groups with regard to postoperative bleeding and cyanosis. Although flap dehiscence was more severe on day 7 in the experimental group, no significant difference was found between the two groups with regard to the percentage of flap dehiscence assessed at other time points. Within limitations of the study, it has been demonstrated that antibiotic use has no effect on implant failure rates in dental implant surgery with a limited number of implants. We conclude that perioperative antibiotic use may not be required in straightforward implant placement procedures. Further randomized control clinical studies with higher numbers of patients and implants are needed to substantiate our findings.

The research was aimed to evaluate the antibiotic susceptibility pattern of Staphylococcus species from clinical samples obtained from some hospitals in Kano metropolis, Nigeria. The ear swab, high vaginal swab (HVS), wound swab and urine samples from the patients attending the hospitals were collected and inoculated onto the surface of freshly prepared Nutrient agar for bacterial isolation. The bacteria isolated were identified by conventional microbiological methods namely; Gram staining, biochemical test (such as catalase, coagulase, and DNase test), mannitol salt agar and heamolysis test. The isolates were subjected to antibiotic susceptibility testing using the agar disc diffusion method. The result showed that S. aureus was highly susceptible to Ciprofloxacin 105 (68.63%), Gentamicin 102 (66.67%), Levofloxacin 95 (62.08%) and Amikacin 90 (58.82%), S. epidermidis was highly susceptible to Gentamicin 13 (61.90%), Levofloxacin 12 (57.14%) and Nitrofurantoin 11 (52.38%) while S. saprophyticus was highly susceptible to Cefoxitin 7 (77.78%), Gentamicin 6 (66.67%) and Nitrofurantoin 5 (55.56%). On the other hand, S. aureus was highly resistant to Cefuroxime 153 (100%), Ceftazidime 150 (98.04%), Amoxicillin/clavulanic acid 120 (78.43%) and Cloxacillin 111 (72.55%), S. epidermidis was highly resistant to Ceftazidime 20 (95.24%), Cloxacillin 19 (90.48%) then Cefoxitin, Erythromycin and Amoxicillin/clavulanic acid with 15 (71.43%) both. S. saprophyticus was highly resistant to Cefepime 9 (100%), Cloxacillin 8 (88.89%), Ceftazidime 7 (77.78%), Imipenem and Erythromycin with 6 (66.67%) respectively. There is a statistical difference in the sensitivity of the isolates against the antibiotics used at p<0.05. It is concluded that Staphylococcus species develop resistance to some classes of antibiotics.

Antagonist Effect

The study objectives were to determine the chemical composition and the synergistic / antagonistic effect of the association between hydroalcoholic extract from the Dorycnii pentaphylli herba (DPH) and the antibiotics of choice, on five reference strains. The tincture contains flavonoids and polyphenol carboxylic acids in low concentrations. DPH has an antagonistic effect on three of the drugs tested (amoxicillin + clavulanic acid, levofloxacin, amikacin), the therapeutic effect being completely canceled and has no significant effect on two of them (ceftazidime, cefotaxime).

Novel Drug

Amoxicillin and clavulanic acid are two of the most commonly prescribed antibacterial worldwide for treating oral infectious diseases. Oral health is of big importance for well-being and general health. A few novel drug delivery systems were designed for oral treatment and prophylaxis of different diseases in the oral cavity. This work focused on the latest drug delivery development of the most common oral pathologies, namely, periodontitis, oral mucosal infections, dental caries and oral cancer. Herein we reveal the synthesis, characterization and application of chitosan nanoparticles for intracellular transport of the weakly cell-penetrating amoxicillin and clavulanic acid in order to improve their efficacy on bacterial infections.

This article discusses the augmenting influence of Artesunate (ART) in combination with β-lactams (amoxicillin/clavulanic acid) antibiotic in sepsis mice models infected by a lethal challenge dose of live coagulase positive enterotoxigenic (Sec) MRSA that was isolated from a case of chronic bovine mastitis. The main goal is to find an appropriate treatment to overcome resistance mechanism of MRSA towards β-lactams antibiotic. Fifty healthy adult Swiss mice divided into 5 equal groups were used in the experimental procedure. The infected group that treated with both ART and β-lactams (amoxicillin/clavulanic acid) antibiotic revealed complete inhibition of MRSA count with complete normal macroscopic and histopathological features. We suggest that ART can potentiate the antibacterial action of β-lactams (amoxicillin/Clavulanic) acid against MRSA infection. The combination of ART and antibiotic can overcome MRSA resistance mechanism and so could be considered a novel candidate to overcome mastitis and/or sepsis caused by MRSA.
