Cough is one of the most common symptoms that doctor faces in working with pediatric population, and according to some characteristics of cough, doctors can often conclude localization, and sometimes even the nature of the disease that causes it. Cough is not only the physiological defense reaction, but a symptom of a disease. According to duration it can be acute, chronic and recidivist, recurrent and persistent, strong or discreet, caused by changes in body position and changes in outside temperature. Pathoanatomically it is divided into lobar, lobular, alveolar and interstitial, pathogenetically to bronchogenic and hematogenous, as well as in immuno competent and immunocompromised, and clinically on the local and inpatient (72 hours after hospital admission)...

Importance: Actinomyces is commonly found in many areas of the body where it derives a benefit without harming the host. When it does infect the host during pregnancy, is that infection a threat to the obstetric patient and does that infection cause adverse pregnancy outcomes? Objective: The aim of this study was to review what is known about Actinomyces infections and the impact of an Actinomyces infection on pregnancy outcomes. Evidence Acquisition: A PubMed search was undertaken with the search years unlimited to April 1, 2016, and restricted to articles in English...

Staphylococcus aureus is recognized as a typical food-born pathogen in food safety, and its rapid detection and typing methods are in desperate need. To study their evolution characteristics and drug resistance condition, Staphylococci isolates were subject to the investigation. Strain identification were subjected to standard procedures (colony morphology, Gram staining, Vitek 2 automated system and the API commercial kit), and fingerprinting was then performed with RAPD-PCR amplification. In this study, 179 isolated staphylococci were identified as MRSA...

Two Gram-stain negative aerobic bacterial strains were isolated from the bark tissue of Populus × euramericana. The novel isolates were investigated using a polyphasic approach including 16S rRNA gene sequencing, genome sequencing, average nucleotide identity (ANI) and both phenotypic and chemotaxonomic assays. The genome core gene sequence and 16S rRNA gene phylogenies suggest that the novel isolates are different from the genera Snodgrassella and Stenoxybacter. Additionally, the ANI, G+C content, main fatty acids and phospholipid profile data supported the distinctiveness of the novel strain from genus Snodgrassella...

Purpose. Low-virulence anaerobic bacteria, especially the Propionibacterium acnes (P. acnes), have been thought to be a new pathogeny for a series of disc diseases. However, until now, there has been no histological evidence to confirm this link. The purpose of this study was to confirm the presence of P. acnes in nonpyogenic intervertebral discs via histological observation. Method. Degenerated intervertebral discs were harvested from 76 patients with low back pain and/or sciatica but without any symptoms of discitis or spondylodiscitis...

Septic arthritis of the wrist can result in permanent damage to the joint, making timely diagnosis crucial to initiate empiric antibiotics and surgical intervention. Although septic arthritis is routinely included in the differential diagnosis of atraumatic wrist pain, the incidence is unknown. Unlike large joints, there is no consensus on cell count values considered pathognomonic for wrist septic arthritis. The goal of this retrospective study was to determine the incidence of wrist septic arthritis and to identify the clinical, serum, and joint fluid values that predict infection...

Gemella is a facultative anaerobic Gram-positive coccus and a rare cause of infective endocarditis (IE). Gram staining may eventually misidentify the organism, which tends to easily decolorize and manifest as either Gram-negative or Gram-variable. Commercial biochemical tests are often used to identify Gemella, but the methods they employ sometimes lack accuracy. A 52-year-old woman was diagnosed with Gemella taiwanensis IE after initial identification of the pathogen as Gemella haemolysans using biochemical tests combined with matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS)...

A G3P2 patient who conceived with an intrauterine contraceptive device (IUD) presented at 20 weeks of gestation with mild irregular uterine contractions and vaginal bleeding. Sonographic examination at admission showed the presence of dense amniotic fluid "sludge" and a long sonographic uterine cervix (42 mms). To assess the microbiologic significance of amniotic fluid "sludge", we performed a transabdominal amniocentesis. The procedure was performed under real-time ultrasound, and fluid resembling pus at gross examination was noted...

Bacteria identification plays a vital role in the field of clinical diagnosis, food industry, and environmental monitoring, which is in great demand of point of care detection methods. In this paper, in order to discriminate the source of nosiheptide product, a plasmonic filter was fabricated to filtrate, capture and identify Streptomycete spores with Surface enhanced Raman Scattering (SERS). Since the plasmonic filter was derived from self-assembled photonic crystal coated with silver, the plasmonic "hot spots" on the filter surface was distributed evenly in a fare good density and the SERS enhancement factor was 7...

Neonatal conjunctivitis is usually associated with vagina's infection by Chlamydia sp., N. gonorrhoeae, and/or other bacteria during delivery. Meningococcal neonatal conjunctivitis is an extremely rare disease. We report a case of neonatal meningococcal sepsis/conjunctivitis and asymptomatic carriage of N. meningitidis from both parents (vagina and nasopharynx). As part of our active surveillance for meningococcal disease at the Tijuana General Hospital (TGH), Mexico, we identified a 3-day-old newborn with meningococcal conjunctivitis and sepsis...
