AI Article Synopsis
- The study analyzed 156 Campylobacter jejuni isolates from poultry and humans using PCR/RFLP typing to identify different strain types.
- The research found a total of 22 different types from three enzymatic digests, with specific types being more common in human (Cj.4, Cj.1) and poultry (Cj.1, Cj.11) strains.
- The results suggest that while poultry contributes significantly to human Campylobacter infections, it is not the only source, highlighting the importance of understanding various sources for risk assessment.
Article Abstract
Aims: The PCR/RFLP typing of 156 isolates Campylobacter jejuni originating from poultry and humans was performed (101 human and 55 poultry strains).
Methods And Results: On the basis of restrictive digest, six types were identified with AfaI, seven types with MboI and five types with HaeIII. With a combination of these three enzymes, 22 types were found. In human strains, the most frequently occurring types were Cj.4 (28%), Cj.1 (19%), Cj. 13 (13%) and Cj. 2 (5%). In the case of poultry strains, the most frequent types were Cj. 1 (34%), Cj. 11 (22%), C.j. 21 (16%) and Cj. 15 (11%).
Conclusions: The findings support the hypothesis that poultry is a significant source but not sole source of Campylobacter sp. in relation to humans.
Significance And Impact Of The Study: The typing of Campylobacter sp. forms the basis for an evaluation of the current state and risk assessment of various Campylobacter sp. sources in relation to humans.

Campylobacteriosis is one of the most commonly reported foodborne diseases and is of particular importance in low-income countries. More data is needed to better understand the epidemiology of Campylobacter spp. in food sold at informal markets, where most people in low-income countries buy their food.

Genomic data on from the African continent are currently lacking, resulting in the region being under-represented in global analyses of infection (CDI) epidemiology. For the first time in Nigeria, we utilized whole-genome sequencing and phylogenetic tools to compare isolates from diarrhoeic human patients (=142), livestock (=38), poultry manure (=5) and dogs (=9) in the same geographic area (Makurdi, north-central Nigeria) and relate them to the global population. In addition, selected isolates were tested for antimicrobial susceptibility (=33) and characterized by PCR ribotyping (=53).

Introduction: Poultry production accounts for 42% of Cameroonian meat production. However, infectious diseases represent the main hindrance in this sector, resulting in overuse and misuse of antimicrobials that can contribute to the emergence and dissemination of antimicrobial resistance (AMR). This study aimed to evaluate the prevalence of antimicrobial resistance genes (ARGs) conferring resistance to carbapenems ( and ), (fluoro) quinolones (, , and ), polymyxins ( to ), and macrolides ( and ) in the poultry farm environment.

Background: Japanese encephalitis (JE) is a zoonotic parasitic disease caused by the Japanese encephalitis virus (JEV), and may cause fever, nausea, headache, or meningitis. It is currently unclear whether the epidemiological characteristics of the JEV have been affected by the extreme climatic conditions that have been observed in recent years.
Objective: This study aimed to examine the epidemiological characteristics, trends, and potential risk factors of JE in Taiwan from 2008 to 2020.

Global demand for food has driven expansion and intensification of livestock production, particularly in developing nations where antibiotic use is often routine. Waste from poultry production, including manure, is commonly utilized as fertilizers in agroecosystems, risking environmental contamination with potentially zoonotic bacteria and antimicrobial resistance genes (ARGs). Here, 33 bacterial isolates were recovered from broiler (n=17) and layer (n=16) chicken manure by aerobic culture using Luria Bertani agar.
