MICROBIOLOGY - Response of the Microbiology area against SARS-CoV-2(COVID19)
The reference technique for performing the microbiological diagnosis of SARS-CoV-2 is real-time PCR, which allows the detection of various virus genes with a sensitivity greater than 98%. At Catlab, various organizational changes were made to deal with the situation, and offer a SARS-CoV-2 diagnostic service 24 hours a day and 7 days a week.

MICROBIOLOGY - Valuation of the screening of Urine cultures in Primary
The diagnosis of urinary tract infections (UTI) is based on three factors: the patient's symptoms, the examination of the urine forms and the urine culture. In 2016, to qualitatively optimize the microbiological diagnosis of UTI, a screening of the urine with culture requested is started. The result of this screening is a clear decrease in negative urine cultures, an increase in positive ones, and a tendency to reduce contaminated urine cultures.

MICROBIOLOGY - Poseidon Project; development of a biosensor for Legionella detection
The Poseidon Project has been funded by the Horizon 2020 Program. Six institutions from 4 European countries participated, including Catlab. The objective was to develop a biosensor to monitor the concentration of Legionella in situ in water systems in high-risk facilities. Catlab's task was to validate the prototype detection and quantification of Legionella in water samples.

MICROBIOLOGY - Tuberculosis
Tuberculosis is an infectious disease caused by the bacterium Mycobacterium tuberculosis. In this bulletin, we will see how it is acquired, how it is diagnosed and how it is treated. The current frequency of the disease, and the tests available to the Laboratory to diagnose it.

Bulletin Nº89 - March 2018

The first step of the microbiological diagnosis begins with obtaining the clinical sample; it must be representative of the infectious process that is wanted to diagnose. All the information that the microbiology laboratory can generate depends almost completely on the sample that is sent. Therefore, it is essential that the obtention procedure, the quantity sent, the type of transport and the appropriate speed of delivery. The consequences of a poorly collected and / or badly sent sample may result in the failure to isolate the etiologic agent of the infection.

MICROBIOLOGY - Diagnosis of Meningoencephalitis
Bacterial meningitis causes 120,000 deaths worldwide each year. The Catlab Microbiology area has recently incorporated a new PCR to detect in a short time the 14 microorganisms that most frequently cause meningitis, encephalitis and meningoencephalitis. It is performed in a single CSF sample and after a minimum manipulation. It allows detecting the microorganism in about 2 hours. Thus, inadequate treatments, over-treatments and improved patient management can be reduced.

Bulletin Nº78 - February 2017

MICROBIOLOGY - Incorporation of mass spectrometry in clinical microbiology
The Catlab Microbiology area has recently incorporated an advanced technology (MALDI-TOF) to identify bacteria and fungi in a few minutes, in contrast to conventional, very slow methods. It provides advantages in the management of the patient with sepsis, since the speed of information improves the quality of health care: it decreases the duration of empirical treatment, adjusts the administration of adequate antibiotics and reduces hospitalization times.

MICROBIOLOGY - Urinary tract infection. New circuit in Catlab
Urinary tract infections are one of the most frequent infectious diseases. The diagnosis of UTI is based on three factors: the patient's symptoms, examination of the formed elements of urine and urine culture. To optimize the microbiological diagnosis of UTI, a retrospective study of all urine cultures obtained by spontaneous urination was performed to set breakpoints that would allow rule planting negative urine cultures and no significant bacteriuria with sensitivity ≥ 95%. From the results, it is proposed to make a screening urine culture, which exclude the cultivation of all urine samples obtained by spontaneous urination, which leucocyte esterase or nitrites are not detected.

MICROBIOLOGY- Diagnosis of Sexually Transmitted Infections
Sexually transmitted infections (STI) are a public health problem that affects a significant number of the population. It is essential to do a reliable and early diagnosis to avoid infection, its spread and possible complications.

Bulletin Nº62 - September 2015

MICROBIOLOGY - Pick-up samples for the study of skin infections and soft tissue
This group of infections is broad and complex. Ranging from skin infections, skin appendages, subcutaneous tissue, fascia and skeletal muscle. They are very common infections of varying severity and can evolve acutely or chronically.
The collection of good quality samples for microbiological analysis, is critical in this process which will determine the microbiological diagnosis.

SEROLOGY - Change of method in serology area
In order to optimize the response time and improve the sensitivity and specificity, we incorporate chemiluminescence technology(QL)instead of some ELISA serology tests.

Bulletin Nº38 - April 2013

MICROBIOLOGY - Collection of samples for the study of superficial mycosis
The diagnosis of superficial mycosis analyzed samples of skin, hair and nails. In all three cases, the area where the sample was collected previously cleaned with 70% alcohol, to remove bacterial flora exudates and excipients medication that may interfere with the search for fungi.

MICROBIOLOGY - Urine culture collection rules
The microbiological diagnosis of urinary infection is one of the most frequent test in laboratories.

Bulletin Nº22 - November 2011

MICROBIOLOGY – Diagnosis of toxigenic Clostridium difficile 
Toxigenic Clostridium difficile is the principal etiologic agent in hospital acquired diarrhea. Its occurence has grown significantly in the last few years, and more virulent strains, such as ribotype 027, have been described as causing hospital acquired outbreaks in the USA and Europe. Thus, the diagnosis must be rapid and reliable.
