“…In our study, several children with campylobacteriosis or NTS were coinfected with other bacterial enteropathogens; this has been increasingly reported recently (17). However, it appears that the clinical severity of bacteria-bacteria coinfection (compared with monoinfection) has not been well documented.…”

Different Age Distribution between Campylobacteriosis and Nontyphoidal Salmonellosis in Hospitalized Korean Children with Acute Inflammatory Diarrhea

We investigated recent epidemiologic trends regarding campylobacteriosis vs. nontyphoidal salmonellosis (NTS), a previously known leading cause of bacterial enterocolitis in Korean children. Among 363 hospitalized children with acute inflammatory diarrhea, Campylobacter (18.7%) was the most frequently detected pathogen using multiplex polymerase chain reaction tests followed by Salmonella (15.4%). Children with campylobacteriosis were older than children with NTS (112.6 months [interquartile range (IQR) 66.0–160.1] vs. 53 months [IQR 31.0–124.0], P < 0.001) and had higher prevalences of abdominal cramping and stool hemoglobin. Campylobacteriosis may be suspected as a primary cause of acute inflammatory diarrhea in hospitalized school-aged Korean children and adolescents.

“…This is due to the secondary importance that this matrix has in the dissemination of this serovar to humans. In fact, several studies suggest eggs, chicken meat, and derivatives as the main culprits in the dissemination of this serovar (53)(54)(55)(56)(57)(58)(59)(60). Therefore, when the source is attributed, studies indicate that pork and pork-based food are the main S. Typhimurium transmission vehicle in Africa and Asia (19,20,61).…”

“…These animals may acquire Salmonella via vertical or horizontal transmission, e.g., from the environment, transportation, feed, and vectors, such as rodents, insects, and humans. After becoming carriers, these animals become Salmonella disseminators through both horizontal and vertical pathways during primary production, when, at this stage, epidemiologists suggest its spread throughout the production chain (54,56,59,100). Some serovars, such as Pullorum and Gallinarum, are specific to birds, causing disease in these animals but rarely in humans, while others, such as Typhimurium, Enteritidis, and Heidelberg, are able to infect a broad range of hosts (10).…”

Salmonella spp. are among the most important foodborne pathogens and the third leading cause of human death among diarrheal diseases worldwide. Animals are the primary source of this pathogen, and animal-based foods are the main transmission route to humans. Thus, understanding the global epidemiology of Salmonella serovars is key to controlling and monitoring this bacterium. In this context, this study aimed to evaluate the prevalence and diversity of Salmonella enterica serovars in animalbased foods (beef, pork, poultry, and seafood) throughout the five continents (Africa, the Americas [North and Latin America], Asia, Europe, and Oceania). The meta-analysis consisted of a chemometric assessment (hierarchical cluster analysis and principal component analysis) to identify the main epidemiological findings, including the prevalence and diversity of the Salmonella serovars in each matrix. Regarding the serovar distribution, S. Typhimurium presented a cosmopolitan distribution, reported in all four assessed matrices and continents; poultry continues to play a central role in the dissemination of the Enteritidis serovar to humans, and Anatum and Weltevreden were the most frequently found in beef and seafood, respectively. Additionally, we recommended careful monitoring of certain serovars, such as Derby, Agona, Infantis, and Kentucky. Finally, given the scientific data regarding the most frequently reported serovars and which matrices constitute the main vehicles for the transmission of this pathogen, control programs may be improved, and specific interventions may be implemented in an attempt to reduce the risk of this pathogen reaching humans. IMPORTANCE Salmonellosis is caused by Salmonella spp. and is the third leading cause of death among food-transmitted diseases. This pathogen is commonly disseminated in domestic and wild animals, and the infection's symptoms are characterized by acute fever, nausea, abdominal pain, and diarrhea. The animals are the primary source of salmonellae, and animal-based foods are the main transmission route to humans. Therefore, data collected from these sources could contribute to future global interventions for effective control and surveillance of Salmonella along the food chain. In light of this, the importance of our research is in identifying the prevalence of Salmonella serovars in four animal-based food matrices (pork, poultry, beef, and seafood) and to evaluate the importance that each matrix has as the primary source of this pathogen to humans.

“…Several persons attending a wedding reception on 26 May 2012 became ill. An outbreak investigation identified chicken liver pâté as the suspected source of the infection. Several Campylobacter outbreaks associated with consumption of poultry liver pâté have been described especially in the UK (Abid et al., ; Edwards et al., ; Farmer et al., ; Forbes et al., ; Inns et al., ; Little et al., ; O'Leary et al., ; Wensley and Coole, ; Young et al., ) but also in other countries such as Australia (Merritt et al., ; Parry et al., ) and USA (Centers for Disease & Prevention, ).…”

In May 2012, an outbreak of campylobacteriosis occurred in southern Sweden at a wedding reception affecting 44 persons. A total of 17 cases were notified (13 were culture positive for Campylobacter spp.). Epidemiological investigation suspected chicken liver pâté as the source of infection. The liver pâté had been deliberately undercooked, lightly fried to keep the right texture and mixed with spices. Campylobacter isolates from six cases as well as three Campylobacter isolates from chicken flocks previously raised by the producer delivering the liver were subtyped using pulsed-field gel electrophoresis and whole-genome sequencing. Indistinguishable PFGE profiles were identified among five human and one chicken C. jejuni isolates as well among the two C. coli isolates, one from a human case and one from a chicken. WGS supported the PFGE findings; the six C. jejuni isolates belonged to one cluster. All these six isolates were of MLST type ST 50 (ST-CC 21). This study highlights the importance of a combination of strict biosecurity at the flock-level as well as adequate cooking of chicken liver to prevent transmission of Campylobacter to humans.
