Haemophili in faeces

Insights

Haemophilus bacteria were found in the feces of 26% of patients and 12% of healthy meatworkers. Most isolates were Haemophilus parainfluenzae, but fecal carriage in the general population remains unknown.

Area of Science:

  • Microbiology
  • Bacteriology

Background:

  • Haemophilus species are known human commensals and pathogens.
  • The presence and prevalence of Haemophilus in human feces are not well-documented.

Purpose of the Study:

  • To investigate the prevalence of Haemophilus in fecal samples from patients and healthy meatworkers.
  • To identify the predominant Haemophilus species found in fecal carriage.

Main Methods:

  • Fecal samples were collected from 612 patients and 525 healthy meatworkers.
  • Samples were plated on a selective medium for the isolation of Haemophilus.
  • Isolates were identified to the species level.

Main Results:

  • Haemophilus was isolated from 26% of patient fecal samples.
  • Haemophilus was isolated from 12% of healthy meatworker fecal samples.
  • The majority of isolates were identified as Haemophilus parainfluenzae.

Conclusions:

  • Haemophilus species, particularly Haemophilus parainfluenzae, are present in human feces.
  • Fecal carriage of Haemophilus is detectable in both patient and healthy populations.
  • Further studies are needed to determine the fecal carriage rate in the general healthy population.

Extrinsic and Intrinsic Pathways of Hemostasis01:20

Extrinsic and Intrinsic Pathways of Hemostasis

Blood clotting or coagulation involves extrinsic and intrinsic pathways, which ultimately merge into the common pathway, forming a fibrin clot.
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which forms a...
Disorders of Hemostasis01:24

Disorders of Hemostasis

Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.
Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...

Serum Laboratory Studies, Stool Test, Breath Test

Gastrointestinal (GI) diagnostic studies are pivotal in confirming, ruling out, diagnosing, or staging various diseases, including cancers. Following diagnosis, allocating time for discussions with the patient and providing informational resources is crucial. Diagnostic assessments of the GI tract often occur in outpatient settings like endoscopy suites or GI labs. Preparation for these tests may include dietary restrictions, fasting, liquid bowel preparations, laxatives, enemas, and the...
Amebiasis01:28

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic Stroke l: Introduction

A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
