Bacterial Contamination of Anterior Chamber Fluid Following Non-complicated Cataract Surgery

1993

Objective: To study the anterior chamber contamination during non-complicated cataract surgery and its relationship with normal conjuctival organisms. Setting: Ophthalmology Department, La Fe Hospital, University of Valencia. Patients: Forty patients who had undergone cataract extraction using either ECCE, phacoemulsification or nucleus fracture methods. Results: Positive cultures of aqueous humour were obtained in 32.5% of cases. The most commonly isolated organism was Staphylococcus coagulase-negative. Only in 7.7% of cases was the microorganism found in the conjunctiva the same as that found in the anterior chamber. The inoculum size ranged between 20 and 160 colonies/ml. One of the case…

Incidence of Staphylococcus aureus in meals from cafeterias

2002

A study to determine the incidence of Staphylococccus aureus in 705 meals from several cafeterias in Valencia, Spain was undertaken. Out of the 705 studied meals, 81 samples (I I. I %) had coagulase positive staphylococci with a range of S. aureus from 100 to 53000 cfu/g. me four highest values (> l0,ooO S. aureus &/g) were obtained with Russian type salad, meatballs, chicken croquettes and salad. These products involved more handling stages. These data show that food handlers may contribute to food poisoning and that there are some handling practices that require more attention.

2014

Results The total number of isolated strains was 413, 231 in 2012 and 182 in 2013. In the intensive care units 151 nosocomial infections were identified; 88 strains in the Surgical Department, 27 strains in the Department of Gynecology and Obstetrics, 24 strains in the Department of Neurosurgery and 23 in the Orthopedic Department. 19 strains were identified in the Neurology Department and also in the Internal Medicine Department, 17 strains were identified in the Urology Department, 14 in the Aesthetic Surgery Department, 8 in the Nephrology Department, 8 in the Hematology Department and 5 in the Gastroenterology Department. 3 strains were isolated in each of the following departments: Dia…

Molecular genetics of Staphylococcus epidermidis biofilms on indwelling medical devices.

2005

Staphylococcus epidermidis is an opportunistic pathogen associated with foreign body infections and nosocomial sepsis. The pathogenicity of S. epidermidis is mostly due to its ability to colonize indwelling polymeric devices and form a thick, multilayered biofilm. Biofilm formation is a major problem in treating S. epidermidis infection as biofilms provide significant resistance to antibiotics and to components of the innate host defenses. Various cell surface associated bacterial factors play a role in adherence and accumulation of the biofilm such as the polysaccharide intercellular adhesin and the autolysin AtlE. Furthermore, recent studies have shown that global regulators such as the …

PO-0779 Which Parameters Are Mandatory In Urinary Tract Infection In Children?

2014

Background The protocol of investigations in urinary tract infection (UTI) in children mandatory includes urianalysis, uroculture, reactive C protein (RCP), blood urea (BUN), renal ultrasonography and scintigraphy. Each one of these has limits to perform in children. Aims To establish the correlations between UTI investigations for argumentation the therapeutic decision. Methods Retrospective study of hospitalised paediatric patients for UTI. The study parameters were: age, symptoms, RCP, BUN, uroculture, renal ultrasonography, urinanalysis (leukocytes, nitrites, pH, density, proteins, erythrocytes, ascorbic acid-AA). Results Were studied 243 hospitalised and treated with antibiotics UTI. U…

Bloodstream infections in intensive care unit patients: Distribution and antibiotic resistance of bacteria

2015

Vincenzo Russotto,1 Andrea Cortegiani,1 Giorgio Graziano,2 Laura Saporito,2 Santi Maurizio Raineri,1 Caterina Mammina,2 Antonino Giarratano1 1Department of Biopathology and Medical Biotechnologies (DIBIMED), Section of Anaesthesia, Analgesia, Intensive Care and Emergency, Paolo Giaccone University Hospital, University of Palermo, Palermo, Italy; 2Department of Sciences for Health Promotion and Mother-Child Care, University of Palermo, Palermo, Italy Abstract: Bloodstream infections (BSIs) are among the leading infections in critically ill patients. The case-fatality rate associated with BSIs in patients admitted to intensive care units (ICUs) reaches 35%–50%. The emergence and diffusi…

Irregular Cytokine Pattern of CD4+T Lymphocytes in Response toStaphylococcus aureusin Patients with Wegener's Granulomatosis

1999

The initial stage of Wegener's Granulomatosis (WG) is often marked by symptoms of infection and it has been postulated that a bacterial infection could be the aetiologic factor of this disease. The objective of our work was to investigate T-cell-mediated immunity in WG by testing proliferative responses on bacterial antigens and particularly Staphylococcus aureus. We investigated the bulk proliferative response of peripheral blood lymphocytes (PBL) from patients with clinically active WG to gram-positive bacteria and purified proteinase 3 (PR-3), the major target antigen of c-ANCA. We generated S. aureus-specific PBL-derived T-cell lines and T-cell clones (TLC). In two WG patients 27 TLC we…

Meticilīnrezistento Staphylococcus intermedius grupas baktēriju identifikācija un izplatība suņiem Latvijā

2015

Meticilīnrezistentā Staphylococcus intermedius grupa (MRSI) ir galvenā rezistento patogēnu grupa mazajiem dzīvniekiem veterinārajā medicīnā. No gandrīz visām veterinārajām klīnikām pasaulē tiek ziņots par arvien vairāk pieaugošo rezistenci, īpašus draudus rada multirezistence. Meticilīna rezistenci nosaka mecA gēns, kas ir insertēts hromosomālā kasetē, pazīstamā kā stafilokoku hromosomālā kasete (staphylococcal chromosomal cassette – SCCmec). Darba mērķis ir identificēt meticilīnrezistentās S. intermedius grupas baktērijas Latvijā un noteikt to izplatību, kā arī optimizēt noteikšanas procedūru. Izmantojot skrīninga metodes, Brilliance MRSA2 agaru un Mannitol Salt agaru ar 2 mg/L cefoksitīnu…

mecA gēna noteikšana klīniskajos Staphylococcus aureus celmos

2017

Staphylococcus aureus ir viens no galvenajiem nozokomiālo infekciju izraisītājiem daudzās attīstītās pasaules valstīs. S.aureus samērā bieži ir meticilīnrezistents, tas nozīmē, ka tam ir rezistence pret visiem klasiskajiem beta laktāmu antibakteriālajiem līdzekļiem. Meticilīnrezistenci nosaka mecA gēns un tā integrācija baktērijas genomā. Baktēriju rezistences pieauguma dēļ būtiski ir noteikt atbilstošu antibakteriālo līdzekļu terapiju efektīvai ārstēšanai. Darba mērķis ir mecA gēna noteikšana klīniskajos Staphylococcus aureus celmos, kas iegūti no pacientiem, kuri ir ilgstoši uzturējušies veselības aprūpes iestādēs. Darbā tika izmantots GenoType® Staphylococcus tests, lai varētu noteikt me…
