Fourteen isolates of Serratia marcescens were collected from patients suffering from septicemia. All theseisolates revealed different levels in tannase production. Tannase was partially purified from Serratia marcescens b9 by precipitation method at 70% saturation of ammonium sulfate. Au, Pt, SnO2 and SiO2 nanoparticles were prepared by laser ablation and examined by transmission electron microscopy (TEM), X-ray diffraction pattern and UV-Visible absorption spectroscopy. Conjugation of SiO2 nanoparticles to tannase by feeding and pulses methods were prepared and characterized by TEM, X-ray diffraction pattern and UV-Visible spectrum...

Bifidobacterium scardovii species consists of facultative anaerobic gram-positive rods whose growth is stimulated by CO2 and anaerobiosis. Exceptionally it has been associated with infections in humans. An elderly male patient with a urinary tract infection due to B. scardovii and Enterococcus faecalis is presented here; both microorganisms were isolated from two consecutive urine samples. The bacillus did not grow on standard media, but on chocolate agar incubated in CO2 and on supplemented Brucella agar in an anaerobic atmosphere, incubated for 72h at 35°C...

PURPOSE OF REVIEW: The discovery of Helicobacter pylori and other organisms colonizing the stomach and the intestines has shed some light on the importance of microbiome in maintaining overall health and developing pathological conditions when alterations in biodiversity are present. The gastric acidity plays a crucial role in filtering out bacteria and preventing development of enteric infections. In this article, we discuss the physiology of gastric acid secretion and bacterial contribution to the composition of gastric and intestinal barriers and review the current literature on the role of proton pump inhibitors (PPIs) in the microbial biodiversity of the gastrointestinal tract...

We recently demonstrated that cow's milk fermented with the probiotic L.paracasei CBA L74 (FM-CBAL74) reduces the incidence of respiratory and gastrointestinal tract infections in young children attending school. This effect apparently derives from a complex regulation of non-immune and immune protective mechanisms. We investigated wheter FM-CBAL74 could regulate gut microbiota composition and butyrate production.We randomly selected 20 healthy children (12-48 months) from the previous randomized controlled trial, before (t0) and after 3 months (t3) of dietary treatment with FM-CBAL74 (FM), or placebo (PL)...

BACKGROUND: Registry data shows that the incidence of acute rejection has been steadily falling. Approximately 10% to 35% of kidney recipients will undergo treatment for at least one episode of acute rejection within the first post-transplant year. Treatment options include pulsed steroid therapy, the use of an antibody preparation, the alteration of background immunosuppression, or combinations of these options. Over recent years, new treatment strategies have evolved, and in many parts of the world there has been an increase in use of tacrolimus and mycophenolate and a reduction in the use of cyclosporin and azathioprine use as baseline immunosuppression to prevent acute rejection...

Urinary tract infections represent one of the most frequent reasons for hospitalization. As a result of their prevalence from community-based origins as well as those which develop in hospital setting, this constellation of infections represents a tremendous burden to the global healthcare system. Areas Covered: Over the last several decades the management of these infections has become more complicated due to the underlying comorbid conditions of the patients as well as escalating antimicrobial resistance to many of the most frequently used oral and parenteral agents...

The pathogenesis of gastric cancer regardless of histological structure is a classic example of gene-environment interaction, and an important epidemiological aspect was the recognized association with Helicobacter pylori infection. This paper describes a case of gastric mucosa-associated lymphoid tissue (MALT) lymphoma in a young patient whose first sign of the disease was upper gastrointestinal bleeding and associated hemorrhagic shock. The patient is a 31-year-old man, diagnosed by endoscopy 10 years ago with H...

Mycoplasma pneumoniae infections mainly involve respiratory tract; however, also can manifestate other symptoms by site involved. Extrapulmonary manifestations of M. pneumoniae infection are rarely known to occur without pneumonia. Herein we report a case of a 9-year-old boy who presented with acute cholestatic hepatitis in the absence of pneumonia. Rhabdomyolysis, skin rash, and initial laboratory results suspicious of disseminated intravascular coagulopathy were also observed in this patient. M. pneumoniae infection was identified by a 4-fold increase in immunoglobulin G antibodies to M...

Sudden perinatal death that includes the victims of sudden infant death syndrome, sudden intrauterine death syndrome, and stillbirth are heartbreaking events in the life of parents. Most of the studies about sudden perinatal death were reported from Italy, highlighting two main etiological factors: prone sleeping position and smoking. Other probable contributory factors are prematurity, male gender, lack of breastfeeding, respiratory tract infections, use of pacifiers, infant botulism, extensive use of pesticides and insecticides, etc...

REVIEW
Ben Shillitoe, Andrew Gennery
Colonel Ogden Bruton reported X-Linked Agammaglobulinaemia in 1952 and treated the child with replacement immunoglobulin therapy. Over 60years later, the treatment for XLA has largely remained unchanged. Replacement immunoglobulin lacks the isotypes IgA and IgM, leading to concerns that patients continue to experience recurrent sinopulmonary tract infections and be at increased risk of bronchiectasis. There is potential hope of earlier diagnosis with newborn screening, and a potential cure for these patients, in the form of gene therapy...

The innate immune system plays an important role in early immunity against respiratory tract infection. Although airway epithelial cells produce mucus to eliminate pathogens and irritants, hypersecretion of mucus is harmful for the host as it may cause airway obstruction and inhibit influx of antimicrobial agents. It has been reported that several antimicrobial agents have an immunomodulatory effect in vitro and in vivo, but little is known about whether tedizolid, a novel oxazolidinone, can modulate immune responses...
