Listeria monocytogenes is an important food-borne pathogen and is widely tested for in food, environmental and clinical samples. Identification traditionally involved culture methods based on selective enrichment and plating followed by the characterization of Listeria spp. based on colony morphology, sugar fermentation and haemolytic properties. These methods are the gold standard; but they ar...

Objective: The CoVIDA project is a public-private collaboration led by Universidad de los Andes that contributed to the SARS-CoV-2 epidemiological surveillance in Bogotá and nearby municipalities. We aimed describe development performance of Drive/Walk-through free RT- PCR for testing strategy implemented CoVIDA. Material method: performed descriptive analysis characteristics centers. model pro...

Chlamydia trachomatis (CT) infection in pregnancy can cause maternal disease, adverse pregnancy outcomes, and neonatal disease [1-6]. In general, approximately 80% of CT infected women are asymptomatic or minimally symptomatic. Therefore, screening is the only means to effectively identify infections [2]. In Japan, pregnant women are routinely tested for CT with the Japanese public funds. Accor...

Aim: The epidemiological characteristics and modes of transmission coronavirus disease 2019 (COVID-19) in children are not yet fully understood. In this study, it was aimed to evaluate clinical, laboratory, radiological findings treatment approaches patients with negative positive PCR tests among those suspected COVID-19 retrospectively. Material Methods: This study conducted 317 under 18 years...

Anaplasmosis and ehrlichiosis are emerging tick-borne diseases with clinically similar presentations caused by closely related pathogens. Currently, laboratories rely predominantly on blood smear analysis (for the detection of intracellular morulae) and on serologic tests, both of which have recognized limitations, for diagnostic purposes. We compared the performance of a published real-time PC...

Background: Underestimation of the number cases during coronavirus disease 2019 (COVID-19) pandemic has been a constant concern worldwide. Detection severe acute respiratory syndrome 2 (SARS-CoV-2) RNA using realtime reverse-transcription polymerase chain reaction (RT-PCR) is most common method to confirm case. However, these tests have suboptimal sensitivity. Objective: The objective study was...

The basis for the identification of SARS-CoV-2 cases in handling COVID-19 pandemic is Reverse Transcriptasi Polymerase (RT-PCR) and specific rapid antigen test. RT-PCR test takes a long time expensive to get results, while simple fast alternative getting detection results. method used descriptive observational form literature review by reviewing existing literature. Several screening confirmato...

The EuropeanAspergillusPCR Initiative (EAPCRI) has provided recommendations for the PCR testing of whole blood (WB) and serum/plasma. It is important to test these recommended protocols on nonsimulated "in vivo" specimens before full clinical evaluation. The testing of an animal model of invasive aspergillosis (IA) overcomes the low incidence of disease and provides experimental design and cont...

INTRODUCTION Currently available antigen tests for norovirus (NoV) have excellent specificity but negative results do not always rule out infection. Real-time reverse transcription polymerase chain reaction (RT-PCR) is a useful method for detecting and genotyping NoV in humans and oysters. An outbreak of NoV associated with oyster consumption in northern New South Wales confirmed the value of r...

Rubella virus infection is typically diagnosed by the identification of rubella virus-specific immunoglobulin M (IgM) antibodies in serum, but approximately 50% of serum samples from rubella cases collected on the day of rash onset are negative for rubella virus-specific IgM. The ability to detect IgM in sera and oral fluids was compared with the ability to detect rubella virus RNA in oral flui...
