Objective:

Acute respiratory infections are one of the most

common infectious diseases. Clinical course of acute respiratory

infections in young children and the elderly may be serious and

life-threatening. It has been emphasized that 20–60% of etiologic

agents are viruses. Respiratory syncytial virus (RSV) is the most

common viral pathogen in children. On the other hand, influenza

virus is the most commonly identified agent in adults. The aim of

this study is to identify the viral pathogens in hospitalized patients

with respiratory tract infection by using multiplex PCR method.

Methods:

Nasopharyngeal swab samples obtained from hos-

pitalized patients with acute respiratory infections were enrolled

between January 2013 and December 2015. The identification of

influenza virus type A and B, human rhinovirus (HRV), respira-

tory syncytial virus A and B (RSV A-B), parainfluenza virus type

1, 2, 3, and 4, adenovirus, bocavirus, human coronavirus, human

enterovirus and human metapneumovirus (HMPV) in nasopha-

ryngeal samples was investigated by using CLART

®

Pneumovir kit

based on clinical array technology (Genomica, Spain).

Results:

Of the 1290 patients included, 1110 (86%) were chil-

dren and 180 (14%) were adults. The number of samples in which

only one virus was identified was 600. In additional 150 specimens,

co-infections ofmultiple viruseswere detected. The total of positive

samples was 750 (58%). The majority of these positive specimens

were children’s samples (694 versus 56). RSV was the most com-

mon viral agent (35%) followed by HRV (13%), and influenza (10%).

The rate of co-existence of viral pathogens was 20%. The multiplex

pcr results were shown in

Table 1 .

Conclusion:

While RSV was the most common viral pathogen

detected inrespiratory infections, other emerging agents, such as

human metapneumovirus, bocavirus, and HRV were detected in

considerably high rates, suggesting these emerging agents should

not be underestimated in the etiology of respiratory infections. In

conclusion, in this study, it was shown that microarray-based mul-

tiplex PCR method is an easy, rapid, and sensitive diagnostic tool

for diagnosis of viral respiratory infections and that utility of this

methodmakes it essential among routine diagnostic tools in clinical

microbiology laboratories.

Objective:

Influenza epidemics occur almost every winter and

are associatedwith considerablemorbidity, mortality and econom-

ical lost. All age groups are susceptible, but increasing age, certain

chronic medical conditions, immundeficiency, pregnancy increase

the risk of complications and death. Influenzae A andB are responsi-

ble for annual epidemics. Quick diagnosis of influenza by laboratory

methods are important for treatment of flu and prevention of epi-

demics.

The aim of this study is to detect prevalence of influenza virus

and its subtypes in patients who admitted to University Hospital in

Konya province with flu like symptoms.

Material and methods:

Nasal swap samples of patients with

flu like symptoms who admitted to various clinics in Necmet-

tin Erbakan University Meram Medical Faculty in Konya; Turkey

between January 1, 2013 and May 25, 2016 were tested for

Influenza A and Influenza B by CLART

®

PneumoVir (Genomica,

Madrid, Spain) micraarray method and Seeplex

®

RV12 ACE Detec-

tion multiplex PCR (Seegene, S. Korea).

Results:

Results of total 2041 samples are analyzed retrospec-

tively. 258 (12.6%) samples were positive for influenza virus. 97

(4.7%) were found to be positive for influenza A and 161 (7.8%) for

influenza B.

Conclusion:

Influenza B was found to be the predominant sub-

type in patients who admitted to hospital with flu-like symptoms

in Konya province. In our study January to March were the months

with the highest percentage of testing positive for influenza virus

infection. Influenza virus can be detected from respiratory sam-

ples with high sensitivity bymolecular methods such as microarray

method and multiplex PCR. Observing seasonal activity and epi-

demic strains and starting early treatment and taking isolation

measures are important for preventing rapid spread and progres-

sion of virus and has critical role for public health.

Introduction:

Human Parainfluenza viruses (HPIVs) are one of

the most common causes of upper and lower respiratory tract ill-

nesses, and an important cause of hospitalizations among children

under 5 years old. There are currently no published data on HPIV

infections in Slovenia.
