Summary
Most broiler chickens in Northern Ireland become infected with Campylobacter spp., primarily Campylobacter jejuni. Infection typically occurs after two weeks of age and is linked to wet litter, with early infections causing mortality.
Area of Science:
- Veterinary Microbiology
- Poultry Science
- Food Safety
Background:
- Campylobacter spp. are a significant cause of foodborne illness globally.
- Broiler chickens are a major reservoir for Campylobacter, posing a risk to human health.
- Understanding the epidemiology of Campylobacter in poultry is crucial for implementing effective control measures.
Purpose of the Study:
- To determine the incidence and characteristics of Campylobacter spp. infection in broiler chickens in Northern Ireland.
- To identify the predominant species and serotypes of Campylobacter isolated from broiler chickens.
- To investigate potential associations between infection, environmental factors, and disease outcomes.
Main Methods:
- Longitudinal monitoring of 12 broiler flocks from placement to slaughter.
- Bacteriological examination of 21 batches of unsolicited birds submitted for postmortem.
- Analysis of 13 batches of day-old chicks (under 36 hours old).
- Isolation and identification of Campylobacter species and serotyping (Penner serotypes).
Main Results:
- Campylobacter spp. were frequently isolated from broiler chickens, with most birds becoming infected.
- Infection was generally not detected during the first two weeks of life.
- Campylobacter jejuni biotype 1 was the predominant species, followed by C. coli and an atypical strain.
- Penner serotypes 1, 3, 5, 9, and 11 were identified, with serotypes 1 and 9 being most common.
- A correlation was observed between wet litter and C. jejuni presence in older birds (>2 weeks).
- Mortality was associated with Campylobacter infection in broilers under two weeks of age.
Conclusions:
- Campylobacter infection is highly prevalent in Northern Irish broiler chickens.
- Early-life infections (<2 weeks) in broilers are associated with mortality.
- Wet litter may serve as an indicator for C. jejuni presence in older broiler flocks.
- Effective farm biosecurity and management practices are essential to control Campylobacter transmission in poultry production.

01:29Bacterial Phylum Chlamydiae
The phylum Chlamydiae or Chlamydiota is composed of a single order, Chlamydiales. This phylum consists entirely of obligate intracellular parasites that infect eukaryotic hosts. While human pathogens within this group have been studied extensively, the phylum encompasses many species capable of interacting with various eukaryotic organisms. Members of Chlamydiae are typically small cocci, approximately 0.5 μm in diameter, and exhibit a distinctive developmental cycle. As is characteristic of...
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...
01:23Stringent Response in E. coli
Bacterial growth is closely tied to nutrient availability, with cells proliferating exponentially under favorable conditions and entering a stationary phase when resources become scarce. This transition is mediated by a regulatory mechanism known as the stringent response, which allows bacteria to adapt to nutrient deprivation by modulating gene expression and metabolic activity.During nutrient scarcity, intracellular amino acid levels decline. It results in the accumulation of uncharged tRNAs...
01:30Bacterial Phylum Actinobacteria
Coryneform bacteria are gram-positive, aerobic, nonmotile rods that exhibit irregular, club-shaped, or V-shaped arrangements. Their V-shape results from snapping division, where the inner cell wall layer forms the cross-wall, while the outer layer remains intact until it ruptures on one side, causing the daughter cells to bend away.The primary genera are Corynebacterium and Arthrobacter. Corynebacterium includes diverse species, ranging from saprophytes to pathogens like Corynebacterium...
01:30Bacterial Phylum Spirochaetes
Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased by a...
01:26Bacterial Phylum Bacteroidota
The phylum Bacteroidota includes over 700 species classified into four primary orders: Bacteroidales, Cytophagales, Flavobacteriales, and Sphingobacteriales. These gram-negative, non-sporulating rods exhibit saccharolytic capabilities and can be aerobic or fermentative, encompassing obligate aerobes, facultative aerobes, and obligate anaerobes. Many species display gliding motility, though some are nonmotile or use flagella. The genus Bacteroides is well-studied due to its significant role in...
