Information regarding Helicobacter pylori antibiotic resistance in Indonesia was previously inadequate. We assessed antibiotic susceptibility for H. pylori in Indonesia, and determined the association between virulence genes or genetic mutations and antibiotic resistance. We recruited 849 dyspeptic patients who underwent endoscopy in 11 cities in Indonesia. E-test was used to determine the minimum inhibitory concentration of five antibiotics. PCR-based sequencing assessed mutations in 23S rRNA, rdxA, gyrA, gyrB, and virulence genes...

Emerging antibiotic resistance in the oropharyngeal microbiota, of which Streptococcus salivarius is a prominent species, represents a challenge for treating pediatric populations. In this study, we investigated the role of S. salivarius as a reservoir for antibiotic resistance genes (ARG) in the oral microbiota by analyzing 95 S. salivarius isolates from 22 healthy infants (2 to 16 months of age). Minimum inhibitory concentrations (MIC) of penicillin G, amoxicillin, erythromycin, tetracycline, doxycycline and streptomycin were determined...

Beta-lactams are known to cause a wide spectrum of neurotoxic manifestations including epileptic seizures. The neurotoxicity of penicillin was first reported in 1945 by Johnson and Walker and is believed to exert an inhibitory effect on gamma-aminobutyric acid transmission of cortical pyramidal cells, due to its beta-lactam ring structure. Epileptogenicity is also a feature of the semisynthetic beta-lactams including aminopenicillins. In this report, we present a patient with a recurrent history of discrete body twitching/jerks of epileptic nature in the context of amoxicillin exposure...

OBJECTIVE: Helicobacter pylori is a bacterial pathogen associated with chronic gastritis, peptic ulcer disease, gastric adenocarcinoma, and gastric mucosa associated lymphoid tissue lymphoma. Current treatment guidelines support a 7- to 14-day, triple-drug protocol consisting of a proton-pump inhibitor (PPI), clarithromycin, and either amoxicillin or an imidazole. The initial eradication rates for this regimen were 80 to 90%. Nevertheless its effectiveness has declined as the antibiotic resistance to clarithromycin and metronidazole has emerged...

BACKGROUND: Bacteria belonging to the Burkholderia cepacia complex (Bcc) are an important cause of chronic respiratory tract infections in cystic fibrosis patients. Intrinsic resistance to a wide range of antimicrobial agents, including a variety of β-lactam antibiotics, is frequently observed in Bcc strains. Resistance to β-lactams is most commonly mediated by efflux pumps, alterations in penicillin-binding proteins or the expression of β-lactamases. β-lactamase inhibitors are able to restore the in vitro activity of β-lactam molecules against a variety of Gram-negative species, but the effect of these inhibitors on the activity of β-lactam treatment against Bcc species is still poorly investigated...

OBJECTIVES/HYPOTHESIS: Eosinophilic chronic rhinosinusitis (eCRS) has recently been recognized as a CRS subtype characterized by inflammation rather than chronic infection. Consequently, the role of antibiotics as a component of maximal medical therapy for eCRS has been called into question. The purpose of this study was to investigate whether the use of antibiotics, which lack any secondary anti-inflammatory properties, are useful in the treatment of eCRS. STUDY DESIGN: Prospective individual cohort study...

BACKGROUND: The availability of safe food improves health of the people that contributes to productivity and provides an effective platform for development and poverty alleviation. On the other hand, unsafe food handling and processing can serve as a vehicle for the transmission of a variety of disease causing agents. The risk of food getting contaminated depends largely on the health status of the food handlers, their personal hygiene, knowledge and practice of food hygiene. Food borne diseases are therefore a public health problem in developed and developing countries which is also true for Ethiopia...

Although the majority of Lyme disease patients can be cured, at least 10-20% of the patients continue to suffer from persisting symptoms such as fatigue, muscular and joint pain, and neurologic impairment after standard 2-4 week antibiotic treatment. While the causes for this post-treatment Lyme disease symptoms are unclear, one possibility is due to Borrelia burgdorferi persisters that are not effectively killed by current antibiotics such as doxycycline or amoxicillin used to treat Lyme disease. A previous study showed that four rounds of ceftriaxone pulse dosing treatment eradicated B...
