Rotavirus gastroenteritis: epidemiological, clinical, therapeutic aspects and economic implications
2013
Results 114 cases were diagnosed with rotavirus gastroenteritis in 2011 and 122 cases in 2012, frequently in the colder months, sex ratio M/F 1.42/1 in 2011, 1.18/1 in 2012 and in the age group 1-3 (58.90% of cases). The clinical severity was assessed by Vesikari score: 91 cases admitted in 2011 (79.82%) and 112 cases admitted in 2012 (91.80%) presenting a medium/severe score. 15 cases presented neurological symptoms and also 15 cases had renal failure. Among the electrolyte disorders the most commonly found was hyponatremia ( 150mEq/L). The hospitalization costs of rotavirus gastroenteritis cases ranged from 58.60€ to 5345 RON (1243.02€).

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…
Management of Intra-abdominal Infections due to Carbapenemase-Producing Organisms.
2014
The prevalence of bacterial resistance to carbapenem antibiotics continues to increase because of bacteria producing metallo-β-lactamases (MBL), called carbapenemase-producing organisms (CPO). Enterobacteriaceae, which can be a common cause of intra-abdominal infections (IAIs), have become carbapenem-resistant Enterobacteriaceae (CRE). Updated international guidelines for the treatment of both IAIs and IAIs due to CRE have been published. Given the multifaceted nature of these infections, these recommendations have been jointly reviewed and endorsed by the Surgical Society and the Association of Medical Microbiology and Infectious Disease. The aims of this review are to summarize the genera…
The effect of Dextransulfate 500 on the pathogenesis of herpes simplex virus infections in weanling mice
1978
Intraperitoneal (i.p.) injection of Dextran Sulfate (D.S.) 500 during a limited period of time influences the course of herpes simplex-virus-infections. D.S.500 was found to reduce the resistance of mice for some herpes simplex-virus strains (Len, L3-2s, Haase) if given between 16 hours before and 2 hours after i.p. infection. The decrease of resistance could be correlated with an increase of the virus content of liver, spleen, brain and spinal cord. Injection of herpes simplex-virus-specific immune serum counteracted the effect of D.S.500 on the course of infections. Conversely, D.S.500 increased the resistance of mice to another group of herpes simplex-viruses (strains D-316, Thea, DD), i…
Epidemiology of foodborne Norovirus outbreaks in Catalonia, Spain
2008
Abstract Background Noroviruses are one of the principal biological agents associated with the consumption of contaminated food. The objective of this study was to analyse the size and epidemiological characteristics of foodborne outbreaks of gastroenteritis in Catalonia, a region in the northeast of Spain. Methods In all reported outbreaks of gastroenteritis associated with food consumption, faecal samples of persons affected were analysed for bacteria and viruses and selectively for parasites. Study variables included the setting, the number of people exposed, age, sex, clinical signs and hospital admissions. The study was carried out from October 2004 to October 2005. Results Of the 181 …
Inhibition of growth of measles virus by mycoplasma in cell-cultures and the restoring effect of arginine
1970
Presence of mycoplasma in MK cell cultures caused an inhibition of measles virus, as revealed by a lower plating efficiency. When arginine is supplemented to the cell-system, mycoplasma contaminated cells yield plaque titers as high as those of uncontaminated cells. The essential role of arginine for plaque formation of measles virus is suggested also by experiments in which arginine added to the agar overlay restored the plating efficiency of measles virus in cultures maintained in a minimal nutrient medium.
Infections of susceptible and resistant mouse strains with herpes simplex virus type 1 and 2.
1980
The spread of HSV of type 1 and 2 was investigated after intraperitoneal, intraplantar and intracerebral infections of resistant (C57/bl) and susceptible (NMRI) mice. The virus spreads after i.p. infection to the spleen and the liver to the same extent in both strains of mice. However, virus is eliminated earlier in resistant mice. Intracerebral infections revealed a peculiar type of resistance of C57/bl mice especially for type 2 of HSV. HSV multiplies in the thymus at the early stage of infection and can be detected in this organ in sick mice of NMRI strain. HSV-1 and 2 can be detected in the spinal cord of C57/bl mice without sickness or death of these animals.
On the hemagglutinating and hemolytic activity of measles virus variants.
1967
The hemagglutinating (HA) and hemolytic (HL) activity of two measles virus variants, differing with regard to type of CPE and other characteristics, have been investigated.

Immune Modulating Effects of NKT Cells in a Physiologically Low Dose Leishmania major Infection Model after αGalCer Analog PBS57 Stimulation
2014
Leishmaniasis is a parasitic infection affecting ∼12 million people worldwide, mostly in developing countries. Treatment options are limited and no effective vaccines exist to date. Natural Killer T (NKT) cells are a conserved innate-like lymphocyte population with immunomodulating effects in various settings. A number of reports state a role of NKT cells in different models of Leishmania infection. Here, we investigated the effect of NKT cells in a physiologically relevant, intradermal low dose infection model. After inoculation of 103 infectious-stage L. major, comparable numbers of skin-immigrating NKT cells in both susceptible BALB/c mice and resistant C57BL/6 mice were noted. Compared …
