River Sediments Downstream of Villages in a Karstic Watershed Exhibited Increased Numbers and Higher Diversity of Nontuberculous Mycobacteria.

The impact of residential villages on the nontuberculous mycobacteria (NTM) in streams flowing through them has not been studied in detail. Water and sediments of streams are highly susceptible to anthropogenic inputs such as surface water flows. This study investigated the impact of seven residential villages in a karst watershed on the prevalence and species spectrum of NTM in water and sediments.

Mycobacteriosis: the most common causative agents.

The annual number of diagnosed diseases caused by non-tuberculous mycobacteria in predisposed individuals remains constant in the Czech Republic. Their clinical characteristics vary depending on the properties of the causative species and its presence and quantity in the immediate environment of the patient. The most common clinically relevant species are Mycobacterium avium, M.

A Rare Case of Osteomyelitis of an Ankle Caused by .

, a rapidly growing nontuberculous mycobacterium, is usually described as a causative agent of soft tissue infections (postsurgical, posttraumatic, posttransplantation, postinjection, catheter infection, etc.), but only rarely as a cause of osteomyelitis. The authors describe a case report of a 72-year-old man with osteomyelitis of the talus.

Dual Infection of an Open Fracture Caused by and .

Infections caused by or are extremely rare. In this report, for the first time a dual infection with these two pathogens is described. An 18-year-old female suffered multiple injuries, including an open comminuted fracture of the right humeral diaphysis after falling from a fifth-floor balcony in January 2019.

Nontuberculous Mycobacteria as Sapronoses: A Review.

Mycobacteria are a unique group of microorganisms. They are characterised by exceptional adaptability and durability. They are capable of colonisation and survival even in very unfavourable conditions.

Mycobacterioses Induced by : Case Studies Indicating the Importance of Molecular Analysis for the Identification of Antibiotic Resistance.

Mycobacterioses are less frequently occurring but serious diseases. In recent years, at a global level, the incidence of mycobacterioses induced by the rapidly growing species (), which is considered to be the most resistant to antibiotics and most difficult to treat, has been on the rise. Correct identification to the level of the subspecies (, , and ) and determination of its sensitivity to macrolides, which are the basis of combination therapy, are of principal importance for the management of the disease.

Within- and between-Breed Selection Signatures in the Original and Improved Valachian Sheep.

This study explored the genomic diversity and selection signatures in two Slovakian national breeds, the Original Valachian and the Improved Valachian sheep. As they are an important animal genetic resource within the country, but with decreasing population size, our aim is to identify potentially valuable genomic regions. A total of 97 sheep (18 male and 79 female) from the Original Valachian, and 69 sheep (25 male and 44 female) from the Improved Valachian populations were genotyped using the GeneSeek GGP Ovine 50 K chip.

Francisella tularensis caused cervical lymphadenopathy in little children after a tick bite: Two case reports and a short literature review.

Although Francisella (F.) tularensis is a well-described and understood zoonotic pathogen, its importance in Central Europe is relatively minor and, as such, tularaemia may be missed in the differential diagnosis. The annual incidence of tularaemia in the Czech Republic is relatively stable with up to 100 reported cases per year, except in the epidemic years 1998 and 1999 with 225 and 222 reported cases, respectively.

Nontuberculous Mycobacteria Prevalence in Aerosol and Spiders' Webs in Karst Caves: Low Risk for Speleotherapy.

A total of 152 aerosol and spider web samples were collected: 96 spider's webs in karst areas in 4 European countries (Czech Republic, France, Italy, and Slovakia), specifically from the surface environment ( = 44), photic zones of caves ( = 26), and inside (aphotic zones) of caves ( = 26), 56 Particulate Matter (PM) samples from the Cave System (speleotherapy facility; = 21) and from aerosol collected from the nearby city of ( = 35) in the Czech Republic. Nontuberculous mycobacteria (NTM) were isolated from 13 (13.5%) spider's webs: 5 isolates of saprophytic NTM (, , , and complex) and 6 isolates of potentially pathogenic NTM ( ssp.

Clinical Relevance and Environmental Prevalence of Group Members. Comment on Mugetti et al. Gene Sequencing and Phylogenetic Analysis: Powerful Tools for an Improved Diagnosis of Fish Mycobacteriosis Caused by Group Members. 2021, , 797.

group (MFG) members are able to cause clinical mycobacteriosis in fish and other animals including humans. , , , , , , , , and were isolated from fish with mycobacteriosis. In other animals only three MFG species have been isolated: from camels' milk, from cutaneous infections often described as "farcy", and from different domestic and wild mammals' species.

Recovery of Mycobacteria from Heavily Contaminated Environmental Matrices.

For epidemiology studies, a decontamination method using a solution containing 4.0% NaOH and 0.5% tetradecyltrimethylammonium bromide (TDAB) represents a relatively simple and universal procedure for processing heavily microbially contaminated matrices together with increase of mycobacteria yield and elimination of gross contamination.

Socio-Economic and Environmental Factors Related to Spatial Differences in Human Non-Tuberculous Mycobacterial Diseases in the Czech Republic.

Non-tuberculous mycobacteria (NTM) are ubiquitous environmental bacteria that can induce pulmonary and non-pulmonary diseases in susceptible persons. It is reported that the prevalence of NTM diseases is increasing in developed countries, but this differs by regions and countries. NTM species distribution and the rate of diseases caused by NTM vary widely in the historical territories of Moravia and Silesia (Czech Republic).

Epidemiology of selected Mycobacterium tuberculosis complex members in the Czech Republic in 2000-2016.

The paper concerns the epidemiology of Mycobacterium tuberculosis complex (MTBC) members except for M. tuberculosis in the Czech Republic in 2000 to 2016. M.

Randomised phase II study of second-line olaratumab with mitoxantrone/prednisone versus mitoxantrone/prednisone alone in metastatic castration-resistant prostate cancer.

Introduction: Platelet-derived growth factor receptor-α (PDGFRα) is expressed in primary prostate adenocarcinoma and in associated skeletal metastases. Olaratumab is a fully human monoclonal antibody that binds PDGFRα and blocks downstream signalling. This phase II study assessed the efficacy and safety of olaratumab in combination with mitoxantrone and prednisone (M/P) versus M/P alone in patients with metastatic castration-resistant prostate cancer (mCRPC) who progressed after docetaxel.

Nontuberculous mycobacteria in the environment of Hranice Abyss, the world's deepest flooded cave (Hranice karst, Czech Republic).

Nontuberculous mycobacteria (NTM) are widely distributed in the environment. On one hand, they are opportunistic pathogens for humans and animals, and on the other hand, they are effective in biodegradation of some persistent pollutants. Following the recently recorded large abundance of NTM in extreme geothermal environments, the aim of the study was to ascertain the occurrence of NTM in the extreme environment of the water zone of the Hranice Abyss (HA).

Virological Quality of Irrigation Water in Leafy Green Vegetables and Berry Fruits Production Chains.

This study condenses data acquired during investigations of the virological quality of irrigation water used in production of fresh produce. One hundred and eight samples of irrigation water were collected from five berry fruit farms in Finland (1), the Czech Republic (1), Serbia (2), and Poland (1), and sixty-one samples were collected from three leafy green vegetable farms in Poland, Serbia, and Greece. Samples were analyzed for index viruses of human or animal fecal contamination (human and porcine adenoviruses, and bovine polyoma viruses), and human pathogenic viruses (hepatitis A virus, hepatitis E virus, and noroviruses GI/GII).

[Bovine tuberculosis still not to be forgotten even in the Czech Republic].

Bovine tuberculosis is caused by two obligate pathogenic species, Mycobacterium bovis and M. caprae, that cause severe disease in animals and humans. The oral route of infection causing extrapulmonary forms of the disease in humans is more common than aerogenic infection causing pulmonary tuberculosis.

Quantitative farm-to-fork risk assessment model for norovirus and hepatitis A virus in European leafy green vegetable and berry fruit supply chains.

Fresh produce that is contaminated with viruses may lead to infection and viral gastroenteritis or hepatitis when consumed raw. It is thus important to reduce virus numbers on these foods. Prevention of virus contamination in fresh produce production and processing may be more effective than treatment, as sufficient virus removal or inactivation by post-harvest treatment requires high doses that may adversely affect food quality.

Spread of Mycobacterium avium subsp. paratuberculosis through soil and grass on a mouflon (Ovis aries) pasture.

The aims of this study were to describe spatial contamination of the environment on a mouflon pasture, as well as to assess the contamination of grass and roots after surface contamination and in depth contamination with feces and buried tissues from animals infected with Mycobacterium avium subsp. paratuberculosis (M. a.

First identification of Mycobacterium avium paratuberculosis sheep strain in Argentina.

We here identified for the first time the presence of Mycobacterium avium paratuberculosis (MAP) sheep (S) strain in Argentina. IS900 polymerase chain reaction (PCR) was positive. The S strain was compared with MAP cattle (C) strains by using IS1311 PCR-restriction endonuclease analysis (PCR-REA), multiplex PCR and restriction fragment length polymorphism (RFLP) analysis.
