The K-
FAST
and K-
SNAP
, two new brief cognitive measures designed for adolescents and adults, were validated against another brief measure--a four-subtest short form of the WAIS-R--using a sample of 20 adult patients hospitalized for depression. Data supported the validity of these two new instruments.

A new short form of the WISC-III was examined with a clinical adolescent sample (N = 30) and the short form estimate of WISC-III Full Scale IQ also served as the criterion for validating two brief cognitive measures, the Kaufman Functional Academic Skills Test (K-FAST) and the K-
SNAP
. Data supported the brevity of the WISC-III short form and the criterion-related validity of both the K-
FAST
and and Kaufman Short Neuropsychological Assessment Procedure (K-SNAP).

One of the biggest limitations in the study and engineering of anaerobic
Clostridium
organisms is the lack of strong fluorescent reporters capable of strong and real-time fluorescence. Recently, we developed a strong fluorescent reporter system for
Clostridium
organisms based on the
FAST
protein. Here, we report the development of two new strong fluorescent reporter systems for
Clostridium
organisms based on the HaloTag and
SNAP
-tag proteins, which produce strong fluorescent signals when covalently bound to fluorogenic ligands. These new fluorescent reporters are orthogonal to the
FAST
ligands and to each other, allowing for simultaneous labeling and visualization. We used HaloTag and
SNAP
-tag to label the strictly anaerobic organisms
Clostridium acetobutylicum
and
Clostridium ljungdahlii
We have also identified a new strong promoter for protein expression in
C. acetobutylicum
, based on the phosphotransacetylase gene (
pta
) from
C. ljungdahlii
Furthermore, the HaloTag and the
SNAP
-tag, in combination with the previously described
FAST
system, were successfully used to measure cell populations in bacterial mixed cultures and showed the simultaneous orthogonal labeling of HaloTag and
SNAP
-tag together with the
FAST
protein reporter. Finally, we show the expression of recombinant fusion protein of
FAST
and the ZapA division protein (from
C. acetobutylicum
) in
C. ljungdahlii.
The availability of multiple strong fluorescent reporters is a major addition to the genetic toolkit of
Clostridium
and other anaerobes that will lead to better understanding of these unique organisms.
IMPORTANCE
Up to this point, assays and methods involving fluorescent reporter proteins were unavailable or limited in
Clostridium
organisms and other strict anaerobes. Green fluorescent protein (GFP), mCherry, and flavin-binding proteins (and their derivatives) have been used only in a few clostridia with limited success and yielded low fluorescence compared to aerobic microbial systems. Recently, we reported a new strong fluorescent reporter system based on the
FAST
protein as a first step in expanding the fluorescence-based reporters for
Clostridium
and other anaerobic microbial platforms. Additional strong orthogonal fluorescent proteins, with distinct emission spectra are needed to allow for (i) multispecies tracking within the growing field of microbial cocultures and microbiomes, (ii) protein localization and tracking in anaerobes, and (iii) identification and development of natural and synthetic promoters, ribosome-binding sites (RBS), and terminators for optimal protein expression in anaerobes. Here, we present two new strong fluorescent reporter systems based on the HaloTag and
SNAP
-tag proteins.
