  1. The Soviet State healthcare system definitely hurt the spread of phage therapy and hindered the treatment of infectious diseases. For one, the resources were severely depleted in the country, along with a shortage of advanced medical knowledge. Penicillin and streptomycin seemed promising but it lacked momentum once it first hit Russia. Also, the fact that the public was urged to use herbs (because they were “ours” and promoted their political agenda) didn’t help prevent any contagious diseases. Perhaps the biggest obstacle to the treatment of infectious disease in Russia was, predictably, politics. The government already provided healthcare free of charge, which was already low quality, but the government also propagated the idea that Western medicine and technology was inherently evil, like the rest of the Western countries. This caused the aforementioned uprising in herbal treatments and “alternative medicine” that served as the main blockade to medical developments in Soviet Russia.
  2. Many different research centers sprouted across Europe as the drive to improve phage therapy swept the continent. The two institutes that are focused on are the Eliava Institute and the Hirszfeld Institute. First, the Hirszfeld Institute was created by Ludwik Hirszfeld in Wroclaw, Poland. Hirszfeld faced many run-ins with Russian officials during the Soviet era, who tried very hard to blockade his work. However, its birth and success are most directly credited to Stalin’s death. After Germany and Russia exchanged control of land during the war, the region containing Wroclaw eventually was filled with the Polish. However, Hirszfeld and his family faced oppression from anti-Semitic movements in Europe, and had to live in the Warsaw Ghetto. After his family’s escape to Wroclaw, he petitioned the local university to create an institute, probably to counteract the now widely accepted Lysenkoic view on biology (as all other views were not welcomed). This history is very similar to the Eliava Institute, where Eliava was forced to be a martyr for his work. Both men were persecuted by the Russian government for attempting to deviate from the norm and forced into unfavorable situations as a result. Although the outcomes were different, both men showed great resilience and did everything in their power to ensure that their scientific endeavors couldn’t be stopped. Their legacies live on in the form of their institutes.
  3. Merill made many great discoveries within the realm of phage therapy but faced one major issue: most, if not all, of the phage he would introduce into a system would be immediately filtered out by the spleen and liver, whose job is to filter out toxins in the body. Merill’s group selected the lambda phage, due to Delbruck’s extensive work with the phage, and injected a large volume into the stomachs of mice. After 7 hours, long enough for the spleen and liver to filter out phage, a blood sample was taken and the phage that resisted the filtration were isolated and reintroduced to the mouse’s system. After serial passaging the phage multiple times, 2 strains were isolated that could remain in the bloodstream much longer than previously believed. These phages were called Argo1 and Argo2. For the experiment, mice were injected with a lethal amount of E. coli bacteria. One mouse was left untreated as a control, one mouse was treated with wild-type phage, and the other two were treated with Argo1 and Argo2. The results showed not only that phage treatment worked on animals, but that the isolated phages were able to stay in circulation much longer due to the mice showing a milder illness at a quicker rate than the wild-type treated mouse. This process made sure that the phages that were able to withstand the filtration process in the animal’s body were selected for, and consequently showed more results when experimentally used.
  4. As time passes, more and more antibiotic-resistant bacteria are developing, meaning that antibiotics will son become less and less effective. Startup companies like GangaGen, mentioned in the book, are seeking to develop treatments and cures that focus on making bacteriophages its primary concern. While antibiotics are currently effective, these companies seek to prepare for when another strategy is needed, especially during a time when antibiotics are believed to be over-prescribed. Companies like GangaGen that possess a wide library of phages will have the resources needed to isolate phages that can potentially wipe out antibiotic-resistant strains of bacterial infections. Experiments like Merill’s need to be performed to prove the effectiveness of a potential phage treatment before it is released to be evaluated by the FDA and other departments or else phage therapy will likely never get it’s feet off of the ground. However, with an advancement in phage therapy, Western medicine will see an opportunity to customize treatments to complex bacterial infections, as well as see an avenue to spread the discoveries around the world to improve healthcare for the rest of the world’s population.

Checking NapoleonB’s Genes 2/20/19

Print Friendly, PDF & Email

Title: Checking NapoleonB’s Genes

Date: 20 February 2019

Rationale: Before the final annotations of NapoleonB are sent in, the genes must be checked for accuracy and any abnormalities double checked and justified.

Tools Used:

  • DNA Master
  • NCBI BLASTp
  • PhagesDB BLAST
  • GeneMark

Procedure:

  • Genes 47 and 48 were checked to ensure that the chosen start was justified by BLASTing and comparing gene products. Other abnormal calls were also checked by the class and any mistakes fixed as observed.

Results/Observations: The results from NCBI and PhagesDB showed that the starts chosen (not the longest available ORF) were justified (due to q1:s1) as well as a worse blast hit when the reading frame was pulled back. No changes were made to the original calls.

Conclusions/Next Steps: Once a final abstract is selected, poster design will commence as well as possibly another check of the NapoleonB annotations to ensure accuracy. Individual research projects will also start soon.

  1. Describe the role that locusts, dysentery, and war had in the discovery of bacteriophage.
    1. D’ Herelle was a scientist that was tasked with working with sickened locusts. By chance, when he was making bacterial assays from the locusts, he noticed that some of the spots had been cleared out on the plate. D’ Herelle named them “taches vierges.” He repeated the same procedure of making plaque assays and kept getting the same, cleared out circles on his plaque assays. He couldn’t replicate it anywhere else and essentially just left it alone until World War I when commercial vaccines started blossoming. French troops came down with a massive case of dysentery, and D’Herelle was assigned to analyzing their stool samples. It was then that he saw the clear spots on the bacterial assays again. He had proof that the clear spots appeared in more than one strain of bacteria, and that the spots only appeared in patients that were getting better from their disease. This led him to the belief that the clear spots were indicative of bacterial death
  2.  Discuss the characteristics of d’Herelle that led him to be a successful scientist. How did he compare to Georgi Eliava?  What happened to the Eliava’s?
    1. D’Herelle was a successful scientist due to his perseverance and passion for his newly discovered “taches vierges” and devoted his studies to understanding what could come out of it, rather than becoming frustrated and disregarding the practice completely. D’Herelle also used his discoveries for good, doing his best to make sure the public could benefit from his early form of gene therapy. Like D’Herelle, Eliava carried the same demeanor and attitude regarding phage therapy. They both were in the same headspace, with similar goals for phage therapy development. The Eliava’s were targeted because of their high profile and pre-Revolution education. The family was put into camps and eventually suppressed in order to fulfill the Soviet Socialist agenda of the time.
  3. Discuss the influence war and politics had on the spread of phage therapy.
    1. Much like the previous response, a political revolution had broken out in Eastern Europe along with a Civil War in Spain, which thickened the plot for Stalin. Personal affairs and politics got in the way of Eliava’s work during the war and caused the relationship between D’Herelle and Eliava to fade. D’Herelle started getting older and was settling down in Paris, beginning to wean himself off of his advocacy for the spread of phage therapy. The combination of the deteriorating relationship and the end of D’Herelle’s career marked the deterioration of the phage therapy revolution.
  4. What are some of the reasons that the spread of phage therapy failed?
    1. Along with politics and war, there were many other reasons why the spread of phage therapy fell short. For example, much of the research done on phages was flawed and conducted in an inconclusive manner, meaning no meaningful conclusions could be drawn. There was also a lot of misunderstanding and ambiguity as to what a bacteriophage was, many people believed it was some sort of enzyme that broke bacteria down. Obviously, this wasn’t the case, but the misunderstanding definitely led to confusion. Lastly, synthetic drugs started to make a rise in the scientific community, leading to a drought in scientific articles regarding phage therapy.
  5. How did the physicists Delbruck and Luria end up as part of the Phage Group? What contributions did they make to phage biology?  Why did phage biology die out in the 70’s?
    1. Delbruck, then a physicist, was interested in the way scientists observe organisms, and how technically an organism cannot be observed without modification. He collaborated with another group of scientists interested in genes and radioactive effects enacted on them by x-rays. They were published in an obscure journal but barely discovered by Schrodinger. Their bride between biology in physics took off from there, especially as Delbruck became more interested in biophysics as a result. In Rome, Luria decided his interest in physics was mostly “amateurish” and wished for something more, so he endeavored in biophysics, coming across Delbruck’s paper. He decided to try and test Delbruck’s ideas on genes and discovered bacteriophages. They both decided to devote their studies to bacteriophages and met at a convention. During their meetings, they established a loosely organized group called the Phage Group that was comprised of scientists of many different specialties. Their collaboration helped drive the spirit behind the group that eventually made progress in the bacteriophage world to the point where Luria, Delbruck, and Hershey won a joint Nobel Prize for their efforts and discoveries. Consequently, the Phage Groups discoveries raised doubts that bacteriophages could truly conquer bacteria. Due to this discovery, the research and new discoveries on phages hit a low and started slowing down. The scientists also started shifting their focus to other fields and more complex organisms.

NapoleonB Annotation 2/13/19

Print Friendly, PDF & Email

Title: NapoleonB Annotation


Date: 
13 February 2019


Rationale: 
The annotations for NapoleonB will be finished and reviewed for accuracy as well as the starterator (ST) annotation completed


Tools:

– Microsoft Surface Pro 5 Tablet
– DNA Master Software
– NCBI BLASTp tool
– HHPred tool
– GeneMark
– PhagesDB BLAST
– Phamerator

– Starterator (PhagesDB)


Procedure: 
Using the above tools, gene 95 were annotated completely
and the starterator annotation completed for genes 45, 47, and 48.

For gene 95:
– A start codon call was made based on the Glimmer/GeneMark call
– The product sequence was BLAST’ed to determine any present function
– A function no-call was made


Results/Observations:
The following picture contains the results of the
annotation for gene 95:

Conclusions/Next Steps: The starterator annotations were finished, giving insight into what information the other phages in the AM cluster revealed about a specific gene’s start. With the exception of one more final review, the genes in NapoleonB have, for the most part, been completely annotated. They will likely be reviewed and any changes made before the analyzation begins on the genome as a whole.

NapoleonB Annotation 2/11/19

Print Friendly, PDF & Email

Title: NapoleonB Annotation

Date: 11 February 2019

Rationale: The annotation for NapoleonB has begun and the genome will be sequenced as thoroughly as possible in order to determine function in relation to other similar phages

Tools: 

  • Microsoft Surface Pro 5 Tablet
  • DNA Master Software
  • NCBI BLASTp tool
  • HHPred tool
  • GeneMark
  • PhagesDB BLAST
  • Phamerator

Procedure: Using the above tools, genes 45-48 were annotated completely (with the exception of starterator “ST”). Gene 46 was deleted due to convincing evidence of a bad call. For each gene:

  • A start codon call was made based on the Glimmer/GeneMark calls or lack thereof
  • The product sequence was BLAST’ed to determine any present function
  • A function call was made and any supporting evidence from PhagesDB, Phamerator, and HHPred was logged

Results/Observations: The following picture contains the results of the annotations:

Conclusions/Next Steps: The starterator annotations need to be completed along with gene 95’s complete annotation. All but one gene was labelled as “NKF,” the gene that was able to be identified was an HTH DNA binding domain protein. Once the remaining genes are annotated, NapoleonB will have a completed annotation ready for analyzing.

Print Friendly, PDF & Email

Title: PhageNotes Entries

Date: 6 February 2019

Tools:

  • Microsoft Surface Pro 5 Tablet

Rationale: With the (near) completion of Elesar annotations, the annotations are to be entered into the PhageNotes spreadsheet.

Procedure: 

  • The already completed annotations for genes 16 and 17 were copied from DNA Master and entered into PhageNotes corresponding to the category and individual annotation. Genes 23 and 60 were also verified for accuracy.

Results/Observations: 

  • Below is a screenshot of the finished product after entering annotations into Elesar PhageNotes:

Conclusions/Next Steps: After learning how to manipulate PhageNotes and appropriately enter annotations, all that is left to learn is Starterator and Synteny in order to have a full repertoire of skills for successfully annotating NapoleonB.
