Sensitivity of Vermamoeba (Hartmannella) vermiformis cysts to conventional disinfectants and protease [PDF]

Journal of Water and Health, 2014
Vermamoeba vermiformis is a free-living amoeba (FLA) widely distributed in the environment, known to colonize hot water networks and to be the reservoir of pathogenic bacteria such as Legionella pneumophila. FLA are partly resistant to biocides, especially in their cyst form. The control of V.

Multiplication of Legionella spp. in tap water containing Hartmannella vermiformis [PDF]

Applied and Environmental Microbiology, 1991
A model was developed to study the multiplication of various Legionella spp. in tap water containing Hartmannella vermiformis. Tap water cultures prepared with the following components were suitable for the multiplication studies: Legionella spp., 10(3) CFU/ml; H.

Efficacy of dental unit disinfectants againstCandidaspp. andHartmannella vermiformis [PDF]

Pathogens and Disease, 2014
Human oral commensal Candida yeasts, as well as environmental free-living amoebae (FLA) such as Hartmannella, are known to be direct or indirect human pathogens. These microorganisms may be isolated from dental unit waterlines (DUWL), because of contamination coming from the tap water and/or a patient's mouth.

Morphological Characterization and Genotyping of Acanthamoeba Isolates From Oral and Nasal Samples of Cancer Patients in Kashan, Iran. [PDF]

Can J Infect Dis Med Microbiol
Background: Acanthamoeba​ species are recognized as the most prevalent free‐living amoebae (FLA). They can cause granulomatous amebic encephalitis (GAE) and pulmonary and ocular infections. The present study aimed to isolate and identify Acanthamoeba genotypes in cancer patients referred to Kashan’s hospitals in Central Iran.

Free-Living Amoebas in Extreme Environments: The True Survival in our Planet. [PDF]

Biomed Res Int, 2022
Free‐living amoebas (FLAs) are microorganisms, unicellular protozoa widely distributed in nature and present in different environments, such as water or soil; they are maintained in ecosystems and play a fundamental role in the biological control of bacteria, other protozoa, and mushrooms.

Amoeba species colonizing the gills of rainbow trout (Oncorhynchus mykiss) in Swiss aquaculture

Journal of Fish Diseases, Volume 46, Issue 9, Page 987-999, September 2023., 2023
Abstract Nodular gill disease (NGD) is an infectious condition characterized by proliferative gill lesions leading to respiratory problems, oxygen deficiency and mortality in fish. Globally, NGD primarily impacts freshwater salmonids in intensive aquaculture systems.

A global review of problematic and pathogenic parasites of farmed tilapia

Reviews in Aquaculture, Volume 15, Issue S1, Page 92-153, February 2023., 2023
Abstract Over the past 80 years, tilapia have been translocated globally for aquaculture; active production is recorded in >124 countries. Of 7 million tonnes of tilapia produced in aquaculture, 79% is from 79 countries outside the natural range of tilapia.

Organic fertilization regimes suppress fungal plant pathogens through modulating the resident bacterial and protistan communities

Journal of Sustainable Agriculture and Environment, Volume 1, Issue 1, Page 43-53, March 2022., 2022
Abstract Introduction Fungal plant pathogens are an emerging threat to economically important crop production worldwide and a significant risk to global food security. However, we have limited knowledge of how agricultural management practices drive the emergence and spread of pathogens within crop microbiomes and the underlying ecological mechanisms ...

The influence of microbial mats on travertine precipitation in active hydrothermal systems (Central Italy)

The Depositional Record, Volume 8, Issue 1, Page 165-209, February 2022., 2022
Three active travertine sites were investigated in Central Italy to identify the types of carbonate precipitates and the associated microbial mats at varying physico‐chemical parameters. This study confirms that microbial communities in hydrothermal settings vary as a function of water temperature.

Antimicrobial Agents Based on Metal Complexes: Present Situation and Future Prospects

International Journal of Biomaterials, Volume 2022, Issue 1, 2022., 2022
The rise in antimicrobial resistance is a cause of serious concern since the ages. Therefore, a dire need to explore new antimicrobial entities that can combat against the increasing threat of antibiotic resistance is realized. Studies have shown that the activity of the strongest antibiotics has reduced drastically against many microbes such as ...
