Primary amebic meningoencephalitis (PAM) caused by the free-living ameba (FLA) Naegleria fowleri is a rare but rapidly fatal disease of the central nervous system (CNS) affecting predominantly young, previously healthy persons. No effective chemotherapeutic prophylaxis or treatment has been identified. Recently, three transplant-associated clusters of encephalitis caused by another FLA, Balamuthia mandrillaris, have occurred, prompting questions regarding the suitability of extra-CNS solid organ transplantation from donors with PAM. During 1995-2012, 21 transplant recipients of solid organs donated by five patients with fatal cases of PAM were reported in the United States. None of the recipients developed PAM, and several recipients tested negative for N. fowleri by serology. However, historical PAM case reports and animal experiments with N. fowleri, combined with new postmortem findings from four patients with PAM, suggest that extra-CNS dissemination of N. fowleri can occur and might pose a risk for disease transmission via transplantation. The risks of transplantation with an organ possibly harboring N. fowleri should be carefully weighed for each individual recipient against the potentially greater risk of delaying transplantation while waiting for another suitable organ. In this article, we present a case series and review existing data to inform such risk assessments. Although Naegleria fowleri solid organ transplant transmission has not been reported to date, human postmortem findings and animal studies suggest that N. fowleri extra-CNS dissemination can occur; therefore the risks of transplantation with an organ from a patient with primary amebic meningoencephalitis should be carefully weighed against the potentially greater risk of delaying transplantation while waiting for another suitable organ. © 2013 The American Society of Transplantation and the American Society of Transplant Surgeons.

This study was driven by court order to examine methods to remove, extract, and STR-type potential DNA entrapped between latent fingerprint lifting tape and matte acetate that was collected from a 1977 crime scene. Results indicate that recovery of appreciable quantities of DNA is more challenging once adhesive is attached to matte acetate cards and even more difficult when fixed following black powder enhancement. STR amplification of extracts from entrapped fingermarks collected following the dusting/lifting procedure did not produce robust profiles, and extraneous peaks not expressed by print donors were detected for some samples. A hearing was set to argue whether there was DNA remaining to be tested, and if so, whether that DNA could be exculpatory in this postconviction matter. The studies herein provided the basis for the court's decision to not require the testing. © 2015 American Academy of Forensic Sciences.

Using molecular genetics, male sexual organ morphology (baculum), and cranio-dental characters, we describe a new spe-cies of the genus Neoromicia from Madagascar, N. robertsi sp. nov. It is presumed to be endemic to the island and is known from three specimens taken in montane areas of the eastern central region. The new species shows 1.0 % and 2.8% divergence in the 12S rRNA and 16S rRNA genes, respectively, from its nearest congener and is notably larger in cranio-dental measurements than other members of the genus occurring on Madagascar. This new species was previously iden-tified as N. melckorum, which is considered a junior synonym of southern African N. capensis. Neoromicia malagasyen-sis, an endemic to central western Madagascar, is the sister species to N. robertsi and the two are best considered vicariant species. Specimens provisionally assigned to N. malagasyensis, but notably smaller in baculum and skull size, and with different baculum morphology, probably represent another unknown species from the island. Given the apparent rarity of N. robertsi compared with other Malagasy members of this genus living in the eastern portion of Madagascar, it is con-sidered a taxon of conservation concern.

Advances in automation have been made for a number of processes conducted in the forensic DNA laboratory. However, because most robotic systems are designed for high-throughput laboratories batching large numbers of samples, smaller laboratories are left with a limited number of cost-effective options for employing automation. The Maxwell 16 Instrument and DNA IQ Reference Sample Kit marketed by Promega are designed for rapid, automated purification of DNA extracts from sample sets consisting of sixteen or fewer samples. Because the system is based on DNA capture by paramagnetic particles with maximum binding capacity, it is designed to generate extracts with yield consistency. The studies herein enabled evaluation of STR profile concordance, consistency of yield, and cross-contamination performance for the Maxwell 16 Instrument. Results indicate that the system performs suitably for streamlining the process of extracting known reference samples generally used for forensic DNA analysis and has many advantages in a small or moderate-sized laboratory environment.
