Summary
Helicobacter pullorum frequently colonizes turkeys, with 76.4% of sampled birds testing positive. Many isolates exhibit antibiotic resistance, raising concerns about food safety and public health.
Area of Science:
- Veterinary Microbiology
- Food Safety
- Antimicrobial Resistance
Background:
- Helicobacter pullorum is an emerging pathogen with zoonotic potential.
- Its prevalence and characteristics in turkey populations are not well-documented.
- Understanding its occurrence is crucial for food safety assessments.
Purpose of the Study:
- To investigate the prevalence of Helicobacter pullorum in intensively reared turkeys.
- To characterize phenotypic and genotypic properties of H. pullorum isolates from turkeys.
- To assess antibiotic resistance patterns in turkey-derived H. pullorum.
Main Methods:
- Sampling of caecum contents from 55 turkeys across 11 farms.
- Isolation of Gram-negative curved rod bacteria using a modified filter technique.
- Identification via polymerase chain reaction (PCR), followed by phenotypic (biochemical, antibiotic susceptibility) and genotypic (PFGE, AFLP) characterization.
Main Results:
- Helicobacter pullorum was detected in 76.4% of turkeys and 100% of farms.
- Isolates displayed similar biochemical profiles but high genetic heterogeneity.
- Ten of 11 isolates showed resistance to at least one antibiotic, notably erythromycin, ciprofloxacin, and nalidixic acid.
Conclusions:
- Helicobacter pullorum is a common intestinal inhabitant in turkeys.
- The high prevalence and antibiotic resistance underscore potential food-borne risks associated with turkey carcasses.
- Further research is needed to clarify the food-borne transmission and public health implications.

01:26Gastritis II: Pathophysiology
The pathophysiology of gastritis begins with the colonization of the stomach lining by Helicobacter pylori (H. pylori). This bacterium spreads mainly via the oral-oral route through saliva or shared utensils, and can also be transmitted in overcrowded or unhygienic environments through contaminated water, despite its brief survival outside the body.ColonizationOnce ingested, H. pylori enters the stomach and begins colonization by navigating through the mucus layer lining the stomach wall. It...
01:27Peptic Ulcer
Peptic ulcers are erosive lesions of the gastric or duodenal lining, most commonly caused by Helicobacter pylori infection. This Gram-negative, helical bacterium has adapted to survive the stomach’s acidic environment by producing urease, which converts urea into ammonia and carbon dioxide. The ammonia neutralizes gastric acid in the bacterium’s immediate environment, allowing colonization of the gastric mucosa. H. pylori attaches to mucus-secreting epithelial cells, penetrates the mucus...
01:16Treating Helicobacter pylori in Peptic Ulcers: Antimicrobial Therapy
Helicobacter pylori, a resilient gram-negative bacterium, can thrive in the stomach's harsh, acidic environment. Infection with H. pylori leads to a cascade of events within the stomach lining. One of the critical disruptions caused by this bacterium is the interference with somatostatin production, a hormone responsible for regulating acid secretion. This interference tips the balance, escalating acid secretion and diminishing bicarbonate levels. This imbalance compromises the defensive...
01:28Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies
Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

01:28Amebiasis
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...
01:18Bacterial Gastroenteritis
Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
