Gold on paper-paper platform for Au-nanoprobe TB detection.

Tuberculosis (TB) remains one of the most serious infectious diseases in the world and the rate of new cases continues to increase. The development of cheap and simple methodologies capable of identifying TB causing agents belonging to the Mycobacterium tuberculosis Complex (MTBC), at point-of-need, in particular in resource-poor countries where the main TB epidemics are observed, is of paramount relevance for the timely and effective diagnosis and management of patients.

Kerion caused by Microsporum audouinii in a child

Kerion celsi is rarely associated with Microsporum audouinii infection. We report the case of a 3-year-old girl with a kerion celsi caused by M. audouinii and successfully treated with oral terbinafine. Fungi identification was made by macro and microscopical colony morphology analyses and molecular (genotypic) studies.

Enhanced Detection of Tuberculous Mycobacteria in Animal Tissues Using a Semi-Nested Probe-Based Real-Time PCR

Bovine tuberculosis has been tackled for decades by costly eradication programs in most developed countries, involving the laboratory testing of tissue samples from allegedly infected animals for detection of Mycobacterium tuberculosis complex (MTC) members, namely Mycobacterium bovis. Definitive diagnosis is usually achieved by bacteriological culture, which may take up to 6–12 weeks, during which the suspect animal carcass and herd are under sanitary arrest.

Detection of Theileria and Babesia infections amongst asymptomatic cattle in Portugal

Piroplasmosis caused by tick-borne hemoprotozoans of several Theileria and Babesia species has a major impact on livestock production worldwide. A reverse line blotting assay that includes genus- and species-specific probes for Theileria and Babesia species was used to assess the occurrence of these parasites in blood samples collected from 1407 healthy bovines throughout mainland Portugal.
