Analysis System

This work deals with the design, fabrication, and thermal characterization of a disposable miniaturized Polymerase Chain Reaction (PCR) module that will be integrated in a portable and fast DNA analysis system. It is composed of two independent parts: a silicon substrate with embedded heater and thermometers and a PDMS (PolyDiMethylSiloxane) chamber reactor as disposable element; the contact between the two parts is assured by a mechanical clamping obtained using a Plastic Leaded Chip Carrier (PLCC). This PLCC is also useful, avoid the PCR mix evaporation during the thermal cycles. Finite Element Analysis was used to evaluate the thermal requirements of the device. The thermal behaviour of the device was characterized revealing that the temperature can be controlled with a precision of ±0.5°C. Different concentrations of carbon nanopowder were mixed to the PDMS curing agent in order to increase the PDMS thermal conductivity and so the temperature control accuracy.

Rhodococcus equi is an uncommon cause of systemic pyogranulomatous infections in goats with macroscopic similarities to caseous lymphadenitis caused by Corynebacterium pseudotuberculosis. Caprine cases have previously been reported to be caused by avirulent R. equi strains. Six cases of R. equi infection in goats yielding 8 R. equi isolates were identified from 2000 to 2017. Lesions varied from bronchopneumonia, vertebral and humeral osteomyelitis, and subcutaneous abscesses, to disseminated infection involving the lungs, lymph nodes, and multiple visceral organs. Isolates of R. equi from infected goats were analyzed by polymerase chain reaction for R. equi virulence-associated plasmid ( vap) genes. Seven of 8 isolates carried the VapN plasmid, originally characterized in bovine isolates, while 1 isolate lacked virulence plasmids and was classified as avirulent. The VapN plasmid has not been described in isolates cultured from goats.
