First of all, what is a hotspot?
A hotspot, is a place with a hotter temperature in relation to its surroundings.
So, when we think of "biodiversity hotspot", what exactly does that mean?
It's a place with a higher biodiversity in relation to its surroundings, but also with more concentration of species.
So, that's why forests are considered a biodiversity hotspot. If you want some visual content, try finding a geographical map of Africa. In some desert regions you'll see green spots (some really big). These are forests. The interesting thing about them, is when you search their biodiversity, you'll see what a biodiversity hotspot looks like

In the case of genetic investigation, scientists used fruit flies as their model organism since they share 75% of the genes that cause disease with humans. Fruit flies are also great to work in a research setting because they are relatively easy to take care of, especially compared to larger and more expensive organisms like rats or fish.Answer:

Answer:
Background
During the course of a bacterial infection, the rapid identification of the causative agent(s) is necessary for the determination of effective treatment options. We have developed a method based on a modified broad-range PCR and an oligonucleotide microarray for the simultaneous detection and identification of 12 bacterial pathogens at the species level. The broad-range PCR primer mixture was designed using conserved regions of the bacterial topoisomerase genes gyrB and parE. The primer design allowed the use of a novel DNA amplification method, which produced labeled, single-stranded DNA suitable for microarray hybridization. The probes on the microarray were designed from the alignments of species- or genus-specific variable regions of the gyrB and parE genes flanked by the primers. We included mecA-specific primers and probes in the same assay to indicate the presence of methicillin resistance in the bacterial species. The feasibility of this assay in routine diagnostic testing was evaluated using 146 blood culture positive and 40 blood culture negative samples.
Explanation:
Results
Comparison of our results with those of a conventional culture-based method revealed a sensitivity of 96% (initial sensitivity of 82%) and specificity of 98%. Furthermore, only one cross-reaction was observed upon investigating 102 culture isolates from 70 untargeted bacteria. The total assay time was only three hours, including the time required for the DNA extraction, PCR and microarray steps in sequence.
