Authors: Dinu S, Szmal C, Damian M, Oprişan G
Abstract
Noroviruses are the leading cause of acute
gastroenteritis, causing significant economic burden
globally. Infection is self-limiting, occurring as sporadic
cases or producing outbreaks associated with
consumption of contaminated water or food. All age
groups are affected and person to person transmission is
frequent. Except a recent outbreak in Romania caused by
the emergent genotype GII.P17-GII.17, few data
regarding the circulation of noroviruses in our country are
available. We retrospectively analyzed stool samples from
acute gastroenteritis patie...

The impact of the molecular diagnosis in the surveillance of the Clostridium difficile infection.
Authors: Bãicuş A, Cîrstoiu M, Lambru K, Plata F, Cîrstoiu CF
Abstract
Clostridium difficile is the agent of many cases of
antibiotic associated diarrhea. The prevalence of the
toxigenic Clostridium difficile strains was assessed by
real-time PCR between May 2014- January 2015, at the
Emergency University Hospital, Bucharest, Romania. The
incidence of the Clostridium difficile infection was 0.47%.
Among the 1119 stool specimens tested, 165 (13.8%)
were positive for C. difficile toxins A and B by
immunochromatography test. All 165 positive samples
were investigated by real time PCR and 134 (81%)
samples...

Expression signature of some immunity genes triggered in Apis mellifera carpatica model by Pseudomonas entomophila experimental infection.
Authors: Neagu A, Raþiu AC, Mihalache (Radu) MR, Lazãr V, Chifiriuc MC, Ecovoiu AA
Abstract
Herein we report the expression profiles of
certain immunity genes from Apis mellifera
carpatica worker individuals experimentally
infected with Pseudomonas entomophila L48
strain. Changes of the relative expression of
abaecin, Relish, dorsal, Toll-1, domeless, and
Duox genes were monitored by qRT-PCR. Our
results were compared with similar ones from
Drosophila melanogaster model and suggest that
these genes are involved in the anti-infective
defense mechanisms. Our study opens
investigation avenues for modern pro...

Resistance pattern of multi-drug resistant strains of Mycobacterium tuberculosis and characteristics of patients with multi-drug resistant tuberculosis.
Conclusion: MDR strains of Mycobacterium
tuberculosis display an increased resistance to first line
anti-TB drugs. Extension of resistance to second line
anti-TB drugs narrows the therapeutic options. Knowledge
of MDR-TB risk factors is imperative for the correct and
rapid initiation of the treatment.

Effects of Pseudomonas aeruginosa infection on the expression profile of transient receptor potential-like (TRPL) gene from Drosophila melanogaster.
Authors: Mihalache (Radu) MR, Raþiu AC, Neagu A, Lazãr V, Chifiriuc MC, Ecovoiu AA
Abstract
In an endeavor to monitor the effects of
experimental infections with Pseudomonas
aeruginosa on gene expression profiles of the
eukaryotic model host, we focused on transient
receptor potential-like (trpl) pleiotropic gene of
Drosophila melanogaster (the fruit fly). Herein we
report qRT-PCR data derived from experimental
infections of male fruit flies with different genetic
backgrounds by pricking and ingesta procedures, as
compared to previous results obtained by microarray
technology consecutive to ingesta exper...

Characterization of MRSA strains by phenotypic and OCR-based methods.
Authors: Luncã C, Iancu LS, Vremerã T, Tuchiluş CG, Dorneanu O
Abstract
With the emergence and spread of new
methicilin resistant Staphylococcus aureus
(MRSA) strains, control of dissemination, both in
hospitals and in the community, requires the molecular
characterization of the circulating strains
in order to establish their dynamics and identify
the sources of infection. During this study we analyzed
the MRSA isolates by means of PCR-based
methods in order to improve epidemiological
surveillance and early application of prevention
measures. The presence of mecA, nuc, lukF-PV
and lukS-PV genes, as wel...

Polyploidization on SK-N-MC human neuroblastoma cells infected with herpes simplex virus 1.
We examined the impact of herpes simplex
virus-1 (HSV-1) on SK-N-MC human neuroblastoma
cell line.
The infected cells were followed from 6 hours up
to 96 hours post infection (hpi). A large number of
polyploid cells with giant nuclei was observed under
the influence of HSV-1 at 24 hpi with the DNA
content of 32c to 64c or more, in comparison with
control SK-N-MC cells that were characterized by
relatively moderate values of ploidy, i.e. 8с to 16с
(where 1c is the haploid amount of nuclear DNA
found in normal diploid populations in G0/G1). After
48-96 hpi, the population of polyploid cells with giant
nuclei decreased to t...

Short communication: Could the genexpert system be a new tool for poliovirus detection in the sewage water?
Authors: Bãicuş A
Abstract
Environmental enterovirus surveillance plays a key
role in the detection and identification of importation of
circulating vaccine-derived polioviruses into polio-free
areas. In 2015, 2 cases of paralytic poliomyelitis caused
by circulating vaccine-derived poliovirus type 1
(cVDPV1), from south-western Ukraine, bordering
Romania, were confirmed. Romania was considered a
country at risk and the environmental enterovirus
surveillance was enhanced. In this context we tried to
find a diagnosis algorithm for the rapid detection of
poliovirus (PV) in the sewage water, using a
combinat...

Mechanisms of resistance to ciprofloxacin and genetic diversity of escherichia coli strains originating from urine cultures performed for romanian adults.
MECHANISMS OF RESISTANCE TO CIPROFLOXACIN AND GENETIC DIVERSITY OF ESCHERICHIA COLI STRAINS ORIGINATING FROM URINE CULTURES PERFORMED FOR ROMANIAN ADULTS.
Roum Arch Microbiol Immunol. 2015 Jul-Dec;74(3-4):73-8
Authors: Cristea VC, Oprea M, Neacşu G, Gîlcă R, Popa MI, Usein CR
Abstract
Urinary tract infections (UTI) with Escherichia coli are among the most common infections presenting in general practice. Fluoroquinolones (FQs) are relied on for their empirical therapy but recent reports indicate a concerning increase in the percentage of FQ-resistant E. coli isolates in many co...

Relative expression of efflux pumps in multi drug resistant pseudomonas aeruginosa.
RELATIVE EXPRESSION OF EFFLUX PUMPS IN MULTI DRUG RESISTANT PSEUDOMONAS AERUGINOSA.
Roum Arch Microbiol Immunol. 2015 Jul-Dec;74(3-4):86-90
Authors: Azimi L, Namvar AE, Jamali S, Lari AR, Bijari A, Lari AR
Abstract
Pseudomonas aeruginosa is known as an important opportunistic pathogen, resistant to a high number of antibiotics. Efflux pumps are one of the main intrinsic antibiotics resistance mechanisms in P. aeruginosa. MexAB-OprM, MexCD-OprJ, and MexXY-OprM are the main efflux pumps involved in beta-lactam resistant strains which may cause cross resistance to different antimicro...

STUDY TO ESTABLISH THE ACCEPTANCE RANGE FOR PEROXYL RADICALS SCAVENGER CAPACITY OF NATURAL SOD.
Roum Arch Microbiol Immunol. 2015 Jul-Dec;74(3-4):91-8
Authors: Lupu AR, Cremer L
Abstract
In the context of an emerging market of food supplements, the proven quality of the antioxidant products should be the main criteria for using them. The production process has to be carefully controlled and complementary tests are needed to demonstrate the correspondence between real and declared properties of final product. Using well characterized compounds with proven antioxidant activity in bi...

Immunological implications in mammalian semi-allogeneic pregnancy.
IMMUNOLOGICAL IMPLICATIONS IN MAMMALIAN SEMI-ALLOGENEIC PREGNANCY.
Roum Arch Microbiol Immunol. 2015 Jul-Dec;74(3-4):99-104
Authors: Krupanidhi S
Abstract
The mammalian conceptus is a semi-allograft. The maternal tolerance towards semi-allograft is primed by a battery of cytokines and resident decidual cells. Invasion of embryonic trophoblast, decidual vascular remodeling and unresponsive incipient 'Triple-negative' (CD3-, CD4- and CD8-) T-cells of foetus promote normal pregnancy. On the other hand, the maternal cytokine profile shift towards Th1 response is shown to enhance the r...

Serum prolactin in melanoma patients with interferon alpha2b treatment.
CONCLUSIONS: The treatment with interferon alpha2b stimulated reversible and non-cumulative prolactin production. Evaluating prolactin in melanoma patients could become necessary in the future, both for finding a possible pituitary disorder, but also for a new pharmacological intervention.

Serological response to vaccines in children with diabetes.
CONCLUSION: Given the results of the study, no difference was found between patients with diabetes and controls who were vaccinated with pertussis, diphtheria, tetanus, mumps and HB vaccines. But there are some concerns about measles and rubella vaccinations that need further investigation.
