This document describes a study that used bioluminescent imaging to track Streptococcus pyogenes (Group A Streptococcus) infection in the nasopharynx of mice over time. Researchers genetically engineered S. pyogenes to express the lux operon from Photorhabdus luminescens, allowing non-invasive imaging of bacteria in live mice using an IVIS imaging system. This revealed that bioluminescent S. pyogenes was able to colonize the nasopharynx and provided a non-invasive way to longitudinally track bacterial infection and clearance following vaccination over multiple time points.

Covid 19
Covid-19 is caused by the SARS-CoV-2 virus. It was first identified in Wuhan, China in December 2019 and has since spread globally in a pandemic. Symptoms can range from mild to severe and include loss of taste/smell, breathing difficulties, fever and cough. Testing methods include RT-PCR. Coronaviruses are spherical with spikes and a lipid bilayer. They have a large RNA genome and replicate by translating their genome inside host cells and assembling new virus particles which are then released.
What you need to know about the coronavirus
Coronaviruses are a group of viruses that can infect both animals and humans. The novel coronavirus (SARS-CoV-2) that causes COVID-19 is threatening global health. Coronaviruses can cause respiratory illnesses like pneumonia and breathing difficulties in severe cases. While coronaviruses are dangerous, research has shown some may have potential medical value in destroying tumor cells. Scientists around the world are working to better detect and treat SARS-CoV-2 through more accurate testing and efficient treatments.
Influenza virus notes
Influenza A viruses can be broken down into sub-types depending on the genes that make up the surface proteins. Over the course of a flu season, different types (A & B) and subtypes (influenza A) of influenza circulate and cause illness.
More Information about Flu Viruses
Types of Influenza Viruses
Influenza A and B viruses are responsible for seasonal flu epidemics each year.
How the Flu Virus Can Change
Influenza viruses can change in two different ways—antigenic drift and antigenic shift.
Transmission of Influenza Viruses from Animals to People
Influenza A viruses also are found in many different animals, including ducks, chickens, pigs, whales, horses and seals.
Antigenic Characterization of Influenza Viruses
“Antigens” are molecular structures on the surface of viruses that are recognized by the immune system and are capable of triggering an immune response (antibody production).
2009 H1N1 Influenza
The influenza A (H1N1) virus that emerged in 2009 caused the first global influenza pandemic in more than 40 years.

Aedes aegypti
The document summarizes research on the Aedes aegypti Toll pathway and its role in controlling dengue virus infection. The results showed that infection with dengue virus induces the Toll pathway in mosquitoes, which exerts an anti-dengue effect. Specifically, infection was found to activate the Toll pathway genes Caspar and Cactus in the mosquito midgut. The conclusions determined that the Toll pathway plays an important role in the mosquito's defense against dengue virus infection, and that the mosquito's natural microbiota may also help modulate dengue virus infection.

1. The document discusses Ebola virus as an emergent pathogen that infects humans and animals in Africa, with a mortality rate of around 80%.
2. It describes tracking the virus through field investigations of outbreaks and laboratory studies to understand its transmission from bats to great apes to humans, evolution, and pathogenesis.
3. It examines routes of human-to-human transmission and strategies to control outbreaks through prevention, as well as perspectives on developing vaccines and therapies and improving global disease surveillance.
Wolbachia and dengue virus
These slides briefly describe the relation of dengue virus and an endosymbiont bacteria Wolbachia. We can eliminate Dengue fever by using the strategy to manipulate mosquito biology such that it would be unable to transfer virus to humans.
Scientists data for covid 19 .
Scientists have found evidence that the coronavirus may be mutating and adapting to humans. Analysis of over 5,300 coronavirus genomes from around the world showed that some strains have gained mutations in the spike protein that the virus uses to infect cells. While the mutations are still rare, they arose independently in different countries and may help the virus spread more easily. Scientists are concerned that more extensive mutations could impact the effectiveness of potential vaccines and treatments being developed that target the spike protein. Ongoing surveillance is needed to monitor any changes in the virus.
Nuhu et al_NAPA 2015_ESBL Uropathogens
This study analyzed 365 urine samples collected from November 2014 to February 2015 in Sokoto, Nigeria. Of the 105 positive cultures, 60.9% contained Gram-negative uropathogens. The most common isolates were E. coli (29.7%), Salmonella arizonae (23.4%), and Klebsiella species (15.6%). Many isolates were resistant to cotrimoxazole but susceptible to nitrofurantoin. Of the 64 Gram-negative isolates, 15 were confirmed as ESBL producers, with E. coli and Enterobacter species being the most common. The study concludes that ESBL-producing Gram-negative uropathogens are present in Sokoto, Nigeria.

1. Viruses are non-living infectious agents that can only replicate inside host cells. They contain genetic material in the form of DNA or RNA surrounded by a protein coat.
2. Early experiments in the late 19th century demonstrated that certain disease-causing agents could be transmitted between hosts and passed through filters, establishing the existence of viruses.
3. Viruses come in a variety of shapes and sizes but are generally quite small, usually between 20-300 nanometers. Their structure includes a nucleic acid core and protein coat called a capsid, which is composed of repeating protein subunits called capsomeres.
Genetically modified mosquitoes
This document provides an overview of genetically modified mosquitoes for vector control. It discusses the mosquito lifecycle and transmission of vector-borne diseases. Methods for vector control include the use of Wolbachia-infected mosquitoes, which have shown promise in suppressing dengue virus in laboratory and field trials by impairing pathogen development. The document also describes techniques using sterile insects like the sterile insect technique (SIT) and release of insects carrying a dominant lethal gene (RIDL). Field trials on the Cayman Islands demonstrated that Wolbachia-infected mosquitoes can successfully introduce and spread the infection within a native mosquito population. However, more studies are still needed before GM mosquitoes can be effectively used for vector control.
Tuberculosis lecture
- Tuberculosis is caused by the bacterium Mycobacterium tuberculosis, which is transmitted through the air when infected individuals cough, sneeze, or speak.
- When M. tuberculosis is inhaled, it can settle in the lungs and be ingested by immune cells. Most bacteria are destroyed, but some may survive and multiply within immune cells.
- From the lungs, the bacteria can spread via the bloodstream or lymphatic system to other parts of the body, such as the kidneys, spine, and brain. This establishes latent TB infection, which can later develop into active TB disease.

A comprehensive study was conducted on E coli for its prevalence in urine samples, of queried cases of urinary tract infection in patients attending Aminu Kano Teaching Hospital (AKTH), Kano. Two hundred and fourteen urine specimens comprising of 123(57.5%) females and 91(42.5%) males of all age group were screened for bacteria. Of the 214 samples, 68 representing (31.80%) were culture positive with E. coli having 32(47.06%), Klebsiella spp 18(26.47%), Staphylococcus spp 10(14.70%), Proteus spp 6(8.82%) and Pseudomonas spp 2(2.94%). Out of the 32(47.6%) of E. coli isolated, 22 were from female and 10 were from males, the highest prevalence occurred within the age range of 21-30 with females taking the lead. Antibiogram of the isolated E. coli showed a markedly good sensitivity of ofloxacin (96.87%), nitrofurantoin and nalidixic acid (93.70%), colistin phosphate (90.62%) and gentamicin (68.75%). E. coli showed the least sensitivity to ampicillin (18.75%). The frequency of E. coli obtained suggests its high prevalence. And this can be reduced using Flouroquinolones as exhibited by the susceptibility profile in this study.

Escherichia coli was the predominant pathogen isolated (70.52%) from the urine cultures of 538 patients with urinary tract infections in Surat, India. Antibiotics like ampicillin showed high resistance rates of over 90% among isolated gram-negative pathogens. However, gram-negative pathogens demonstrated the highest sensitivity to amikacin, netromycin, piperacillin/tazobactum and cefoperazone/sulbactum with resistance rates below 5%. The study highlights the increasing antimicrobial resistance seen with commonly used antibiotics and identifies alternative antibiotic options for empirical therapy of urinary tract infections in the region.
