Stanley discovered the bacterium Helicobacter pullorum in 1994. After being found in chickens, it was also found in people suffering from gastroenteritis. H. pullorum regularly colonizes the gastrointestinal tract of chickens and causes gastroenteritis. It can be transmitted to humans through contaminated meat, causing colitis and hepatitis.
This bacterium naturally infects a variety of poultry, rodents, and humans. H. pullorum infection is associated with gastroenteritis in farmed poultry such as chickens, turkeys, and guinea fowl. Burnens [1994] states the disease is associated with Vibrion hepatitis lesions in chickens.
Several studies have been carried out to determine the occurrence of H. pullorum in various locations. According to research conducted in Poland, 23% of the freshly slaughtered chicken meat samples from various producers proved positive for H. pullorum. In Italy, H. pullorum infested 58% of free-roaming farm chickens and 100% within the grill, egg layers & healthy farm chickens.
In Belgium, bacterial isolates from the intestinal tract and even the livers of broiler chickens tested positive for the bacterium in the cecum 33%, jejunum 10%, colon 31%, and liver 4%. H. pullorum genotype using 16S rRNA PCR on isolates collected from 900 fecal, cloacal, and liver samples in Egypt discovered a 39% occurrence in grill chicken farms.
H. pullorum has also been connected to human infections. A case report described a 35-year-old male who developed H. pullorum bacteremia & complained of abdominal pain & diarrhea. In Iran, researchers identified a six percent prevalence of H. pullorum in human diarrheal samples. Another study used fecal samples to recover 35 harmful bacteria from diarrheal kids under five.
Furthermore, evidence links H. pullorum with a 2 to 28% prevalence in gall bladder malignancies, as documented in Sweden, Germany, China, and Japan. Another species, Helicobacter bilis, has been associated with gall bladder cancer and has been shown to resist high bile stress.

Helicobacter pullorum is a type of gram-negative bacterium with a curled rod form. It has a single polar flagellum that is not encased. The bacterium is 3-4 micrometers long and 0.3-0.5 micrometers wide.
H. pullorum is a bacterium that moves and does not produce spores. It requires a low oxygen atmosphere known as microaerophilic conditions for maximum growth and survival. Its lipopolysaccharide (LPS) contains essential components like 3-hydroxy tetra decanoic acid & 3-hydroxy hexadecanoic acid.
In reference to H. pullorum strains, the human variant MIT 98-5489 shows rifampin resistance induced by four mutations that missense in the RpoB gene. Another multidrug-resistant strain, 2013BJHL, was recently determined. Genes associated with antibiotic resistance in H. pullorum genomes were identified, including APH (3′)-IIIa, AAC (6′)-Ie-APH (2′’)-Ia and APH (2′’)-If showing resistance to certain antibiotics.
Helicobacter pullorum has two different pglB genes, pglB1 and pglB2. These genes serve locus. H. pullorum‘s pglB1 protein has oligosaccharyl transferase exertion, which is implicated in protein glycosylation.
The two-component system (TCS) of H. pullorum is made up of an AmtB ammonium transporter followed by a PII protein, which is made up of the HPMG439 protein and its corresponding histidine kinase (HK) HPMG440. This TCS is most likely responsible for detecting and responding to environmental stimuli.
H. pullorum has multiple virulence factors contributing to its pathogenicity & host cell colonization. These include the cell-binding factor 2, flagellin (a flagellum protein), and the type 6 secretion system (T6SS) proteins Hcp and VgrG. The cell-binding factor 2 promotes bacterial adhesion to host cells, whereas the polar flagellum facilitates first contact between H. pullorum,and host cell’sreaction by a microvillusand flagellumproximity. The T6SS and the CdtB toxin are essential in H. pullorum‘s invasion into host cells.
Pathogenesis of Helicobacter pullorum involves several virulence factors that contribute to the pathogen’s potential to cause disease. H. pullorum, like Campylobacter and other Helicobacter species, has been found in people with cholecystitis, liver problems, cirrhosis, or bacteremia.
Its involvement in the etiology and progression of cirrhosis, particularly in patients associated with the Hepatitis C virus, appears likely. Furthermore, there has been discussion about the relationship between H. pullorum infections and inflammatory bowel disease.
Several virulence factors in H. pullorum contribute to its pathogenesis. The type III secretion system of bacteria releases a toxin called Cdt, and a newly discovered type VI secretion system (T6SS) is one of them. When H. pullorum targets human gastrointestinal epithelial cells cell lines, human liver cells, gallbladder epithelial cells, or colon epithelial cells, it stimulates the expression of matrix metalloproteinases, or MMPs, such as MMP-9 & MMP-2. These MMPs help to break down the extracellular matrix, which allows bacteria to connect with host cells.
The flagellum of H. pullorum permits it to interact with host intestinal microvilli, producing the pro-inflammatory cytokine IL-8 and intestinal cell colonization. The interaction and invasion process causes edoema and the generation of cell debris, which affects host cells.
Bacterial adherence to the epithelial lining is essential for releasing IL-8, which causes inflammation in gastric epithelial cells. Also, the cytolethal distending toxin (CDT) & lipopolysaccharide (LPS) of H. pullorum, causing inflammation by stimulating the NF-kB pathway, are studied.
Helicobacter pullorum, a bacterium recognized by TLR5, promotes signaling pathways like the NF-B pathway via MyD88 and the IRAK serine kinase. NF-κB signaling is regulated by genes like NFKBIA & TNFAIP3, which assist in maintaining immunological balance and modulate the inflammatory response.
When infected with Helicobacter pullorum, immune cells like macrophages & dendritic cells (DCs) release pro-inflammatory cytokines such as IL-6, IL-8, & TNF-α. These cytokines are essential in launching and enhancing the immunological response to the bacteria.
TLR5 is engaged in gut homeostasis and connects the innate & adaptive immune systems in addition to recognizing Helicobacter pullorum. The adaptive immune response, driven by T and B cells, aids in the detection & targeting of Helicobacter pullorum, hence strengthening host defense mechanisms.
H. pullorum has been isolated from individuals with gastroenteritis, characterized by symptoms such as diarrhea, abdominal pain, nausea, vomiting, and sometimes fever.
H. pullorum infection has been linked to colitis, an inflammation of the colon, which can cause symptoms such as abdominal pain, diarrhea (sometimes bloody), rectal bleeding, and urgency to have bowel movements.
Hepatitis: The swelling of the liver. Symptoms may include fatigue, jaundice (yellowing of the skin and eyes), abdominal pain, nausea, and changes in liver function tests.
Some reported cases have described H. pullorum-induced bacteremia, especially in immunocompetent individuals, presenting with symptoms such as abdominal pain and profuse diarrhea. Additionally, there have been speculations about the possible association of H. pullorum infection triggering inflammatory bowel disease.
Culture method:Helicobacter pullorum cultivation from clinical samples can be complicated, and selective media for its isolation are not routinely used. However, several attempts have been made to construct selective media for H. pullorum. Campylobacter Blood Free Selective Agar (CCDA) combined with selective antibiotics is a popular selective media.
Helicobacter pullorum colonies are typically tiny, spherical, and grayish white. The colonies could be translucent or slightly opaque. Because H. pullorum is a microaerophilic bacterium, it requires incubation in a microaerobic environment (about 5% oxygen, 10% carbon dioxide, & 85% nitrogen) at about 42°C.
Histopathological examination: A biopsy of the afflicted tissue can be conducted if H. pullorum is suspected of causing gastrointestinal or liver-related symptoms. The examination may reveal inflammatory infiltrates within the liver parenchyma, characterized by lymphocytes, plasma cells, and occasionally neutrophils, as well as evidence of hepatocellular injuries, such as hepatocyte ballooning, necrosis, and apoptosis. Chronic active gastritis with infiltration of inflammatory cells in the stomach mucosa, including lymphocytes & plasma cells, can be observed.
The stool antigen test: It is a commonly used method to detect H. pullorum infection. It identifies specific proteins (antigens) associated with H. pullorum in a stool sample. The test is relatively simple and non-invasive, as it requires collecting a small sample of stool and analyzing it in the laboratory. The presence of H. pullorum antigens indicates an active infection.
A stool PCR test can also detect H. pullorum infection in stool samples. PCR is a sensitive molecular technique that can identify the genetic material (DNA) of H. pullorum bacteria. In addition to detecting the infection, the PCR test can provide information about specific mutations in the bacterial DNA that may confer antibiotic resistance.
Ensure proper cooking of poultry and other meat products, as heat treatment can help eliminate or reduce H. pullorum contamination.
Store food at appropriate temperatures to avoid bacterial growth and follow standard food storage recommendations, like rapidly refrigerating perishable items and eliminating expired or ruined foods.
