Viral Meningitis

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

Bacterial Meningitis I: Introduction

Bacterial Meningitis I: Introduction

Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...

Bacterial Meningitis

Bacterial Meningitis

Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...

Encephalitis l: Introduction

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...

Bacterial Meningitis II: Pathophysiology

Bacterial Meningitis II: Pathophysiology

Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.

Summary

This summary is machine-generated.

Researchers induced aseptic meningitis in cats using sterile saliva filtrate from parotitis cases. This meningitis, characterized by a favorable prognosis, was transmissible via cerebrospinal fluid, which remained bacteria-free.

Pathology

Background:

Parotitis, or mumps, can cause neurological complications.
Aseptic meningitis is inflammation of the meninges not caused by bacterial infection.
Understanding the transmission and etiology of meningitis is crucial for animal health.

Purpose of the Study:

To investigate the potential for inducing aseptic meningitis in cats.
To determine if the induced meningitis is transmissible between feline subjects.
To identify the causative agent of this experimentally induced meningitis.

Main Methods:

Intrathecal injection of sterile saliva filtrate from early parotitis cases in cats.
Subsequent injection of cerebrospinal fluid from affected cats into naive cats.
Bacteriological culture of cerebrospinal fluid to assess for microbial presence.

Main Results:

Aseptic meningitis with a 3-5 day duration and favorable prognosis was successfully induced in cats.
The induced meningitis was transmissible to other cats via cerebrospinal fluid.
Cerebrospinal fluid samples remained consistently bacteria-free throughout the study.

Conclusions:

Sterile saliva filtrate from parotitis cases can induce transmissible aseptic meningitis in cats.
The causative agent is non-bacterial and likely viral or other acellular infectious agent.
This model provides insights into the pathogenesis of certain types of meningitis.
