This document discusses global health security threats from biological sources. It outlines emerging infectious diseases, antimicrobial resistance, and other biological dangers such as bioterrorism and dual-use research. Emerging diseases are spreading more rapidly due to factors like population growth, travel, and climate change. Antimicrobial resistance has risen dangerously as misuse of antibiotics grows. Strong detection, prevention and response are needed worldwide to address biological threats that ignore borders. International cooperation is essential for global health security.

Los días 7 y 8 de mayo de 2015 organizamos en la Fundación Ramón Areces con la Fundación General CSIC el Simposio Internacional 'Microbiología: transmisión'. La "transmisión" en microbiología hace referencia al proceso por el que material genético es transferido de una célula a otra, de una población a otra. Es un proceso clave para entender el origen y la evolución de los seres vivos. El objetivo de esta reunión era conocer mejor la logística de la transmisión para ser capaces de modular o suprimir algunos procesos de transmisión dañinos.
“Microbial forensics” has been defined as “a scientific discipline dedicated to analyzing evidence
from a bioterrorism act, biocrime, or inadvertent microorganism/toxin release for attribution
purposes” (Budowle et al., 2003). This emerging discipline is still in the early stages of
development and faces substantial scientific challenges to provide a robust suite of technologies
for identifying the source of a biological threat agent and attributing a biothreat act to a particular
person or group. The unlawful use of biological agents poses substantial dangers to individuals,
public health, the environment, the economies of nations, and global peace. It also is likely that
scientific, political, and media-based controversy will surround any investigation of the alleged
use of a biological agent, and can be expected to affect significantly the role that scientific
information or evidence can play. For these reasons, building awareness of and capacity in
microbial forensics can assist in our understanding of what may have occurred during a biothreat
event, and international collaborations that engage the broader scientific and policy-making
communities are likely to strengthen our microbial forensics capabilities. One goal would be to
create a shared technical understanding of the possibilities—and limitations—of the scientific
bases for microbial forensics analysis._ NCBI

Limbah yang dihasilkan rumah sakit dapat berwujud padat, cair, dan gas yang dapat bersifat infeksius, mengandung mikroorganisme patogen serta bahan-bahan kimia beracun yang berbahaya bagi kesehatan maupun lingkungan. Rumah sakit di Indonesia menghasilkan limbah dalam jumlah yang tidak sedikit, dimana limbah ini dapat berbahaya bagi kesehatan dan dapat mencemari lingkungan. Hasil studi pengolahan limbah cair rumah sakit di indonesia menunjukkan hanya 53,4% rumah sakit yang melaksanakan pengolahan limbah cair. Pemeriksaan kualitas limbah cair hanya dilakukan oleh 57,5% rumah sakit. Ini mencerminkan bahwa betapa besar potensi rumah sakit untuk mencemari lingkungan dan kemungkinannya menimbulkan masalah-masalah lain serta penularan penyakit. Limbah cair mempunyai standar batas maksimal untuk suatu limbah dapat dibuang ke lingkungan yang disebut baku mutu limbah cair. Bagi rumah sakit, baku mutu limbah cair berarti batas maksimal limbah cair yang diperbolehkan dibuang ke lingkungan dari suatu kegiatan rumah sakit.
Selain hal tersebut di atas, rumah sakit merupakan salah satu fasilitas kesehatan yang sangat dibutuhkan oleh, dan adanya rumah sakit sangat diharapkan oleh masyarakat. Keberadaan rumah sakit yang berada di tengah masyarakat dan di tengah pemukiman menjadi perhatian khusus dalam dalam pengelolaan air limbah yang menjadi produk yang bisa berdampak secara negatif. Oleh karena itu rumah sakit harus dapat melakukan pengelolaan limbah baik padat maupun cair secara baik sehingga tidak berdampak negatip terhadap penduduk, atau bila ada dampak negatip maka dampak tersebut dapat diperkecil. Air limbah rumah sakit merupakan salah satu sumber pencemaran lingkungan yang sangat potensial.
Salah satu sumber utama pencemaran dari rumah sakit adalah sejumlah besar air dan juga menghasilkan sejumlah besar air limbah yang didalamnya meliputi mikroorganisme, logam berat, bahan zat kimia beracun, dan unsur radioaktif. Hal ini disebabkan karena air limbah rumah sakit mengandung senyawa organik yang cukup tinggi juga kemungkinan mengandung senyawa-senyawa kimia lain serta mikro-organisme patogen yang dapat menyebabkan penyakit terhadap masyarakat di sekitarnya. Dampak dari air limbah ini merupakan ancaman serius bagi kesehatan manusia dan lingkungan. Oleh karena potensi dampak air limbah rumah sakit terhadap kesehatan masyarakat sangat besar, maka setiap rumah sakit diharuskan mengolah air limbahnya sampai memenuhi persyaratan standar yang berlaku.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

level can lead to higher incidence of water-borne infectious and
toxin-related illnesses, such as cholera and shellfish poisoning.
17
18. Preparedness Actions for EID
• Surveillance
• Robust outbreak investigation practices
• Transmission prevention through containment and control
measures
• Delivery of medical countermeasures
• Public messaging
• Recovery to a “new normal”

20. Antimicrobial Resistance (AMR)
• AMR: Microorganisms (including bacteria, viruses, fungi, and parasites)
resistant to antimicrobials (such as antibiotics, antivirals, antifungal drugs, and
antiparasitic drugs).
• Superbugs: Bacteria develop resistant to majority of antibiotics commonly
used today.
• Multidrug-resistant (MDR). Resistant to multiple antimicrobials. The new
bacteria takes 9 to 11 months to treat MDR tuberculosis.
• Extensively drug-resistant (XDR). Resistant to most antimicrobials.
susceptible to only one or two antimicrobial categories.
• Pandrug-resistant (PDR). Resistant to all antimicrobials.
20
21. Antimicrobial Resistance (AMR)
• AMR is accelerated by the misuse and overuse of antibiotics, as well as
poor infection prevention and control.
• AMR that developed in your body may harm you, your families,
environment, other people , society as a whole.
• Each year more than 700,000 people die due to AMR . The death could
rise up to 10,000,000 people per year, by 2050.
• 200,000 to 250,000 tons of antimicrobials are consumed worldwide each
year. About 70% are consumed by animals and 30% are by humans.

and/or undermining social stability
Biological warfare a specialized type of warfare involving the use of biological
agents conducted by a government against a target (human, agriculture, or
infrastructure)
Bioterrorism: the threat or use of a biological agent (or toxin) against humans,
animals, or plants by individuals or groups motivated by political, religious,
ecological,……
Bioterrorism aims to create casualties, terror, societal disruption, or economic
loss, inspired by ideological, religious or political beliefs. bioterrorism cause
economic losses by infecting livestock or crops, or contaminating buildings.
Biocrime: the threat or use of a biological agent for murder, extortion, or
revenge
33. Advantages and Disadvantages of Using Biologicals
• Advantages
• Small quantities and cheap may have dramatic effects.
• Difficulty in diagnosing index cases.
• Symptoms can mimic endemic, naturally occurring diseases.
• Disadvantages
• Biological agents may affect the health of the aggressor.
• Weather conditions directly affect dispersion.
• Weather conditions lessen the survivability of some organisms.

34. History of Biological Warfare
• 1356 siege of Kaffa, Tartars catapulted cadavers of plague
victims over city walls
• 1710 :Russian attack on Swedish city of Reval, used plague
corpses in attack
• 17th: British army distributed blankets infected with smallpox
virus to native Americans
• 2001—anthrax attacks in the United States
36. Dual Use Research of Concern (DURC)
• DURC :misuse of life sciences research conducted for legitimate
scientific purposes.
• DURC“Life sciences research that, based on understanding, can provide
knowledge, information, products, or technologies could be directly
misapplied to pose a threat with potential consequences to public health
and safety, agricultural crops and other plants, animals, the environment,
materiel, or national security”
• 2001 Ron Jackson of Australian National University found that inserting
an Interleukin 4 gene in mousepox killed the animals (including many that
had been vaccinated for mousepox). They had been trying to create a
vaccine to stimulate antibodies against mouse eggs to make the animals
infertile. The mousepox virus as a vector to carry egg proteins to trigger
an immune response, and the IL-4 was to boost antibody production 36
38. Genome editing
• Technique enables precise modification of the nucleic acid sequences
• overproduction intended metabolites including green chemicals and fuels.
• To this end, genome editing and expression control are performed by
recruiting a series of genetic tools, including
• Antisense RNA
• RNA interference (RNAi)
• transposon mutagenesis
• RecA ,Red-based homologous recombination
• zinc finger nucleases (ZFN)
• Transcription activator-like effector nucleases (TALEN)
• CRISPR-Cas9 technology.
38
39. CRISPR Technology
• CRISPR adaptive immune systems derived from the immune systems in
bacteria and archaea against foreign nucleic acids,phages and plasmids.
• The Cas9 endonuclease can drive DNA binding and cleavage through an
engineered single guide RNA (sgRNA) sequence .
• Editing genes can mean removing or replacing an existing gene,
switching a gene on or off, or inserting a new gene altogether
• Researchers order the sequence of guide RNA to include a part of the
gene they're interested in, plus the Cas binding sequence, mix it with the
Cas protein to suit the job and they're ready to go

42. Synthetic Biology
• Synthetic biology : design and construction of new biological parts, devices and
systems and the re-design of existing biological systems.
• The ability to synthesize any genomic sequence both naturally occurring and artificial
• Transform bacteria and viruses with selected genes, recreate known but difficult to
attain pathogens (including extinct ancient pathogens), and even create novel
microbial genomes is a growing reality.
Studying genes, altering cell lines to study diseases, generating therapeutic solutions,
and bioenergy
• Generate a microorganism to use as a biological weapon or could create unintentional
consequences of an accidental release. 42

Technique Example
Transferring genes B.anthracis to E.coli
Gene shuffling rearranging gene
sequence
Removing part of a gene in Ebola (more
toxic)
Synthetic microbes gene sequences as
building blocks and splicing together
• Live polio virus (synthetic
oligonucleotides)
• Adding IL-4 to mousepox genome,
virus was able to kill mice vaccinated
against mousepox
Hybrid viruses (recombining related
strains )
Dengatitis virus (HBC & dengue to find
a vaccine for HBC)
