Antimicrobial susceptibility and virulence-associated genes in Campylobacter isolates from milk and wastewater in Hatay, Turkey Ciência Rural
Elmalı,Mehmet; Can,Hayriye Yeşim.
ABSTRACT: Campylobacter is one of the most common causes of bacterial foodborne diseases throughout the world. This study was conducted to determine the prevalence, antimicrobial resistance and virulence of Campylobacter isolates of raw cow’s milk and cattle slaughterhouse wastewater samples in Hatay, Turkey. A total of 114 raw milk and 78 wastewater samples were analyzed for the identification of C. jejuni, C. coli, and C. lari by multiplex PCR. The overall prevalence of Campylobacter was found to be 7.2%, of these isolates, 85.7% were identified as C. jejuni and 14.2% as C. coli, but C. lari was not detected in the study. The cdtA and cadF genes were present in 66.6% and 41.6% of C. jejuni isolates tested, respectively, but wlaN gene was not found in...

Boukerb, Amine M.; Penny, Christian; Serghine, Joelle; Walczak, Cécile; Cauchie, Henry-michel; Miller, William G.; Losch, Serge; Ragimbeau, Catherine; Mossong, Joël; Mégraud, Francis; Lehours, Philippe; Bénéjat, Lucie; Gourmelon, Michele.
During a study on the prevalence and diversity of members of the genus Campylobacter in a shellfish-harvesting area and its catchment in Brittany, France, six urease-positive isolates of members of the genus Campylobacter were recovered from surface water samples, as well as three isolates from stools of humans displaying enteric infection in the same period. These strains were initially identified as members of the Campylobacter lari group by MALDI-TOF mass spectrometry and placed into a distinct group in the genus Campylobacter, following atpA gene sequence analysis based on whole-genome sequencing data. This taxonomic position was confirmed by phylogenetic analysis of the 16S rRNA, rpoB and hsp60 (groEL) loci, and an analysis of the core genome that...

Campylobacter in broiler slaughter samples assessed by direct count on mCCDA and Campy-Cefex agar BJM
Gonsalves,Camila Cristina; Borsoi,Anderlise; Perdoncini,Gustavo; Rodrigues,Laura Beatriz; Nascimento,Vladimir Pinheiro do.
ABSTRACT Campylobacter spp. cause foodborne illnesses in humans primarily through the consumption of contaminated chicken. The aim of this study was to evaluate the United States Department of Agriculture's (USDA) recommended methodology, protocol MLG 41.02, for the isolation, identification and direct plate counting of Campylobacter jejuni and C. coli samples from the broiler slaughtering process. A plating method using both mCCDA and Campy-Cefex agars is recommended to recover Campylobacter cells. It is also possible to use this method in different matrices (cloacal swabs and water samples). Cloacal swabs, samples from pre-chiller and post-chiller carcasses and samples of pre-chiller, chiller and direct supply water were collected each week for four...

Campylobacter sp in eggs from cloacal swab positive breeder hens BJM
Fonseca,Belchiolina Beatriz; Soncini,Ricardo Alfredo; Gimarães,Adelia Rodrigues; Rossi,Daise Aparecida.
Campylobacter sp is a microaerophilic, thermotolerating Gram negative bacterium, known to be one of the main causes of food-borne human infections. Among the foods that carry these microorganisms, the chicken is outstanding. In Brazil, a large chicken exporting country, few researches are conducted about their prevalence in breeder hens and the transmission through eggs. The aim of this research was to verify the presence of Campylobacter sp in the shells and within the eggs from positive cloacal swab breeder hens. Microbiological analyses were made on cloacal swabs of 140 weighed breeder hens. The positive breeder hens were set aside and in a total of 244 of their eggs, Campylobacter sp was present in macerated shells and yolk contents during 7 weeks. Out...

Controlling Campylabacter in the Chicken Meat Chain: A Cost-Utility Analysis AgEcon
Mangen, Marie-Josee J.; Havelaar, Arie H.; Nauta, Maarten J.; de Koeijer, Aline A.; de Wit, G. Ardine.
The aim of this study was the estimation of cost-utility of interventions to control Campylobacter contamination of broiler meat. The relative risk, the intervention costs, the disease burden (expressed in DALYs) and the costs-of-illness for the various interventions were necessary inputs for the cost-utility analysis. The cost-utility is expressed in net costs per reduced DALY. The most cost-effective interventions are: reduction of faeces leakage in the slaughter line and decontamination of the carcass by dipping in a chemical solution. Phage therapy might be another cost-effective intervention, depending on assumed costs/chicken. Irradiation is the most efficient intervention, but the least cost-effective.

Effect of refrigeration and frozen storage on the Campylobacter jejuni recovery from naturally contaminated broiler carcasses BJM
Maziero,Maike T.; Oliveira,Tereza Cristina R. M. de.
Campylobacter jejuni is the most common thermophilic Campylobacter associated with human enteritis in many countries. Broilers and their by-products are the main sources for human enteritis. Refrigeration and freezing are used to control bacterial growth in foods. The effect of these interventions on survival of Campylobacter jejuni is yet not quite understood. This study evaluated the effect of storage temperature on the survival of C. jejuni in chicken meat stored for seven days at 4ºC and for 28 days at -20ºC. The influence of selective enrichment on recovery of Campylobacter was also evaluated. Thirty fresh chicken meat samples were analyzed and 93.3% was contaminated with termotolerant Campylobacter spp. with average count of 3.08 Log10 CFU/g on...

Estimated Annual Costs of Campylobacter-Associated Guillain-Barre Syndrome AgEcon
Buzby, Jean C.; Roberts, Tanya; Allos, Ban Mishu.
Guillain-Barre syndrome (GBS) is an autoimmune reaction that can cause acute neuro-muscular paralysis. Of an estimated 2,628 to 9,575 new U.S. cases with GBS annually, 526 to 3,830 are triggered by infection with Campylobacter, the most frequently isolated cause of foodborne diarrhea. Estimated total annual costs of Campylobacter-associated GBS of $0.2 to $1.8 billion plus previously estimated costs of campylobacteriosis ($1.3 to $6.2 billion) add to total annual costs from Campylobacter of $1.5 to $8.0 billion (1995 dollars). Assuming 55-70 percent of costs are attributable to foodborne sources, costs of campylobacteriosis from food sources ($0.7 to $4.3 billion) and costs of associated GBS ($0.1 to $1.3 billion) combined equal total annual costs of $0.8...

Estimating the Costs and the Disease Burden Associated With Campylobacter Infections and Sequelae in the Netherlands AgEcon
Mangen, Marie-Josee J.; Havelaar, Arie H.; de Wit, G. Ardine; Bernsen, Rob A.J.A.M.; van Koningsveld, Rinske.
Campylobacter infections pose an important public health problem in the Netherlands. Approximately 79,000 persons per year are estimated to experience symptoms of acute gastroenteritis. Further annually some 1400 ReA cases, 60 GBS cases and 11 IBD cases are associated with a previous Campylobacter infection. Using a stochastic simulation model the disease burden and the cost-of-illness of Campylobacter infections and its sequelae were estimated. Estimates of the Campylobacter-associated disease burden and costs-of-illness were 1185 DALYs (90% C.I. 693 - 1845 DALYs) per year and some 21 million E (90% C.I. 10 - 38 million E) per year respectively.

Growth capacity of thermotolerant campylobacters in culture media supplemented with pig and cow blood BABT
Tresierra-Ayala,Álvaro; Navas,Manuel; Flores,Josué; Perea,Ramsés; Huanaquiri,Juan; Bendayán,María; Fernández,Heriberto.
In this work 60 thermotolerant Campylobacter strains (37 C. jejuni and 23 C. coli) isolated from the cows, pigs, chickens and ducks (15 strains of each type of animal) were used to establish their growth capacity on media containing cow or swine blood as potential substitutes of sheep or horse blood. The growth capacity was assessed by viable counts on cow and swine blood media, using the modified Miles and Misra method. Campylobacter strains showed better growth in the media supplemented with pig or sheep blood than with cow blood. Thus, the use of pig blood could be a supplement for Campylobacter culture medium, when there was no availability of sheep or horse blood.

Incidence of Campylobacter in pigs with and without diarrhea Rev. Microbiol.
Modolo,José Rafael; Margato,Luiz Florêncio Fernandes; Gottschalk,Arnold Frederico; Lopes,Carlos Alberto de Magalhães.
Two hundred pigs (1- 21 weeks old), from five piggeries in São Paulo State, Brazil, were divided in two groups of 100 animals each, G1 with diarrhea and G2 without diarrhea. Campylobacter was recovered from 43% of G1 and 34% of G2 specimens, and was more frequently recovered from 0-4 week old piglets. C. coli was the most common species (44.2% in G1 and 32.4% in G2), followed by C. jejuni/coli (16.3% in G1 and 23.5% in G2). Campylobacter counts were significantly higher in G1 (<FONT FACE="Symbol">£</FONT> 108 UFC/g) than in G2 (<FONT FACE="Symbol">£</FONT> 104 UFC/g) (p &lt; 0.01), which suggests that the bacterium may play a role at least in the aggravation of the diarrheic process.

Isolamento de Campylobacter jejuni em feto ovino abortado: relato de caso Arq. Bras. Med. Vet. Zootec.
Vargas,A.C.; Cecim,M.; Viana,L.R.; Spricigo,D.A.; Costa,M.M..
Relata-se o isolamento de Campylobacter jejuni de um feto ovino abortado no terço final da gestação. Em uma semana, observaram-se quatro casos de aborto em ovelhas com quatro meses de gestação. Imediatamente após o terceiro aborto, um dos fetos foi submetido a exame patológico, quando se realizou a colheita do conteúdo do abomaso para análise bacteriológica. À necropsia, somente foram evidenciadas alterações autolíticas. Apenas na microaerofilia encontrou-se crescimento bacteriano puro com características morfo-tintoriais de Campylobacter sp., identificado fenotípica e molecularmente como C. jejuni. Alerta-se para a possibilidade de quadros de abortos em ovinos serem causados por esse patógeno.

Livestock Production and Foodborne Diseases from Food Animals in Thailand OAK
PADUNGTOD, Pawin; KADOHIRA, Mutsuyo; HILL, Glen; 門平, 睦代; ヒル, グレン.
Thailand is a developing nation dependent on agriculture. Due to lack of modern public health practices, she suffers from the consequences of foodborne illnesses. The number of foodborne infection cases has nearly doubled in the past 10 years. Salmonella and Campylobacter pose the greatest risk of bacterial contaminants, mostly from pigs and chickens, and this paper will review livestock production systems and foodborne diseases from cases stemming from these sources. Due to the complexity of the livestock production systems, collection of data to date has been sporadic, but it is clear that controls are needed in slaughterhouse processing methods, and more communication between agencies and surrounding regions is paramount for proper surveillance to have...

Occurrence and antimicrobial resistance of Campylobacter jejuni and Campylobacter coli isolated from domestic animals from Southern Ecuador Ciência Rural
Toledo,Zorayda; Simaluiza,Rosa Janneth; Fernández,Heriberto.
ABSTRACT: Occurrence and antimicrobial resistance profiles of Campylobacter jejuni and C. coli strains isolated from fecal samples of dogs, pigs, cows and hens in southern Ecuador were studied. Of the 250 samples studied, 84 (33.6%) were Campylobacter positive, with C. jejuni being more frequent (78.6%) than C. coli (21.4%), with the exception of porcine samples, from which C. coli was the only species isolated. Multidrug resistance was reported in 10 Campylobacter strains (11.9%), four C. jejuni and six C. coli, and was always associated with nalidixic acid and ciprofloxacin resistance. All of the amoxicillin-resistant strains were susceptible to amoxicillin-clavulanic acid and were therefore beta-lactamase producers. However, one strain of C. jejuni...

During a 2-year study, the presence of human pathogenic bacteria and noroviruses was investigated in shellfish, seawater and/or surface sediments collected from three French coastal shellfish-harvesting areas as well as in freshwaters from the corresponding upstream catchments. Bacteria isolated from these samples were further analyzed. Escherichia coli isolates classified into the phylogenetic groups B2, or D and enterococci from Enterococcus faecalis and E. faecium species were tested for the presence of virulence genes and for antimicrobial susceptibility. Salmonella members were serotyped and the most abundant serovars (Typhimurium and its monophasic variants and Mbandaka) were genetically characterized by high discriminative subtyping methods....

Occurrence of Campylobacter in the genitals of teaser bulls maintained at an embryo transfer center Arq. Bras. Med. Vet. Zootec.
Modolo,J.R.; Lopes,C.A M.; Genari,T..
Em central de transferência de embriões, após os procedimentos de reconhecimento do cio em 37 vacas receptoras, através de quatro rufiões vasectomizados, observou-se que 83% delas apresentavam retorno ao cio e algum corrimento serofibrinoso. Nos exames bacteriológicos realizados nos lavados prepuciais dos rufiões foi isolado o Campylobacter fetus subsp. venerealis em todos, fato que, analisado associadamente com o retorno ao cio das vacas receptoras, é indicativo da ocorrência de campilobacteriose no plantel. Essa ocorrência demonstra a necessidade de medidas eficazes de planejamento de saúde animal, pela utilização de rufiões com desvio lateral do pênis. Uma vez impossibilitado o contato sexual, seria impedida a transmissão do agente durante o coito....

Risk factors and likelihood of Campylobacter colonization in broiler flocks Rev. Bras. Ciênc. Avic.
Kuana,SL; Santos,LR; Rodrigues,LB; Borsoi,A; Moraes,HLS; Salle,CTP; Nascimento,VP.
Campylobacter was investigated in cecal droppings, feces, and cloacal swabs of 22 flocks of 3 to 5 week-old broilers. Risk factors and the likelihood of the presence of this agent in these flocks were determined. Management practices, such as cleaning and disinfection, feeding, drinkers, and litter treatments, were assessed. Results were evaluated using Odds Ratio (OR) test, and their significance was tested by Fisher's test (p<0.05). A Campylobacter prevalence of 81.8% was found in the broiler flocks (18/22), and within positive flocks, it varied between 85 and 100%. Campylobacter incidence among sample types was homogenous, being 81.8% in cecal droppings, 80.9% in feces, and 80.4% in cloacal swabs (230). Flocks fed by automatic feeding systems...

Sources of poultry meat contamination with thermophilic Campylobacter before slaughter BJM
Franchin,Paulo Rogério; Aidoo,Kofi E.; Batista,Cleide Rosana Vieira.
The possible sources of Campylobacter spp. in poultry meat before slaughter were studied by examining samples of feathers, cloaca swabs, litter swabs, transport coops, rinse water from coop washing equipment, and chicken breast supports in the slaughter line just before stunning. The samples were collected from 8 broiler houses and from 8 different producers, from a poultry integration system in southern Brazil. The study was carried out over a 12-month period, and each broiler house was sampled in three consecutive flocks, for a total of 24 flocks/broiler house. Campylobacter was found in 79.2% of the feather samples, followed by cloacal swabs (75.0%) and transport coop (50.0%), litter (37.5%), breast support (33.3%) and coop rinse water (25.0%) samples....
