Subviral Agents

Subviral Agents

Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...

Viral Recombination

Viral Recombination

Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Acute Pharyngitis

Acute Pharyngitis

Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:

Pneumonia I: Introduction

Pneumonia I: Introduction

Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Transmission-based Precautions I: Contact, Enteric, and Droplets

Transmission-based Precautions I: Contact, Enteric, and Droplets

Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand RNA genome. Its genome consists of four main open...

Arbovirology
Public Health
Infectious Diseases

Background:

Oropouche virus (OROV) is an emerging arbovirus transmitted primarily by Culicoides midges and Culex mosquitoes.
First identified in 1955, OROV has expanded its geographic range, causing epidemics and recently impacting non-endemic areas.
Clinical presentations range from mild febrile illness to severe neurological conditions like meningitis, with recent evidence of severe fetal outcomes due to vertical transmission.

Purpose of the Study:

To provide a comprehensive review of Oropouche virus (OROV).
To highlight epidemiology, clinical features, diagnostic challenges, and current prevention/treatment strategies.
To inform public health interventions and guide future research efforts.

Main Methods:

Literature review encompassing epidemiology, clinical manifestations, and diagnostics.
Analysis of diagnostic techniques including serological and molecular methods (nested RT-PCR, viral isolation, immunofluorescence).
Assessment of current and potential OROV prevention and treatment strategies, including vaccine development.

Main Results:

OROV epidemiology is characterized by increasing geographic spread, influenced by environmental factors like deforestation and climate change.
Diagnostic difficulties arise from overlapping symptoms with other arboviruses (dengue, chikungunya).
Vaccine candidates (VSV-OROV, epitope-based mimics) are under investigation, and travel-related cases underscore the need for global surveillance.

Conclusions:

OROV poses a significant and expanding public health challenge, necessitating robust surveillance and control measures.
Effective vector control and personal protective measures are essential for OROV prevention.
Continued research into diagnostics and vaccine development is critical for mitigating OROV's impact.
