“…Salmonella was isolated from 9.1% (8 0f 87) of ostriches. Many studies have been conducted on the presence of Salmonella in poultry and avian species but there are few studies on the isolation and identification of Salmonella from ostrich and some studies indicated that Salmonella infection could increase chicks mortality (Arshad et al, 2006;Chiari et al, 2013;Silva-Hidalgo et al, 2012).…”

Poultry salmonellosis, one of the most prevalent diseases and major source of food-borne infections to humans due to consumption of poultry products is worldwide in distribution. The aim of this study was to investigate the incidence of salmonellosis in ostriches by culture and PCR , determination of antibiotic resistance pattern of the isolates and the infected ostriches antibody level. 87 fecal samples from one industrial ostrich farm with clinical signs of diarrhea, weight loss, mortality and reduced hatchability were collected and evaluated for presence of the Salmonella. Salmonella was isolated according to standard culture and biochemical tests. The Salmonella positive samples were serotyped with O and H antisera based on slide and tube agglutination tests. PCR was done for detection of serovars Infantis and Enteritidis. Then the antibiotic resistance against 14 antimicrobial agents were tested. The antibody level of the infected ostriches were measured by WIDAL agglutination test. Results indicated 9.1% (8 of 87) of ostriches were positive for Salmonella. Serotyping results showed 3 samples were serovar Infantis and 5 samples were serovar Enteritidis and PCR confirmed the serotyping results. All 8 samples were resistant to tetracyclin and ampicillin but sensitive to other antibiotics including ciprofloxacin, kanamycin, sultrim, cephalothin, norfloxacin, chloramphenicol, flumequine, nitrofurantoin, coamoxiclav, gentamicin, enrofloxacin and cefotaxime The results of WIDAL agglutination test indicated that all ostriches were negative except 8 Salmonella positive ostriches with the titres 1/80 to 1/360 for the O and 1/80 to 1/640 for the H antigens. To our knowledge this is the first study which reports the peresence of Salmonella Infantis in ostriches in Iran and more studies should be done to investigate this pathogen in ostriches herds of Iran.

“…Its causes include the consumption of black pepper [32], cheese [33], fruit salad (including cantaloupe and honeydew melons) [34], semi-dry cuttlefish [35], and chocolate [36]. In Mexico, this serotype has been isolated from farm [37] and zoo [38] animal feces, from meat for human consumption [28], and from fields where cantaloupe melon was grown [39].…”

Introduction: Gastroenteritis outbreaks in prisons represent a public health risk worldwide. Identifying and characterizing the etiological agents of gastroenteritis outbreaks in prisons is important for implementing effective prevention and infection control measures. We present the first studied case of a gastroenteritis outbreak in a Mexican prison. Methodology: Rectal swab samples were obtained from affected inmates. Standard microbiological techniques were used for isolating Salmonella enterica. Isolates were typed by PCR assays of DNA repetitive elements (ERIC, BOX, REP) and RAPD. Antibiotic resistance profiles were performed by the Kirby-Bauer method. Results: S. enterica serotype Oranienburg was responsible for the outbreak affecting 150 inmates. All patients presented diarrhea, and 70% of them also presented vomiting, with no fatal cases. The origin of the outbreak was undetermined due to the difficulty of gathering epidemiological information, but was likely the result of consumption of shrimp broth or a cantaloupe melon beverage. REP, BOX, and ERIC analyses of 26 serotype Oranienburg strains resulted in Simpson discrimination index (D) values of 0, 0.5507, and 0.5661, respectively. The D values from DG93-RAPD analyses and from the combined ERIC-BOX-DG93 markers were 0.7753 and 0.6092, respectively. All strains showed multiresistance to antibiotics. Conclusions: This is the only studied case of a gastroenteritis outbreak in a Mexican prison, and of the first such outbreak caused by serotype Oranienburg. The combined ERIC, BOX, and RAPD markers adequately assessed the genotype diversity of analyzed strains. Penitentiary personnel or inmates involved in outbreaks might spread multiresistant strains outside of the facility.

“…Si bien los alimentos de origen animal han sido descritos (1999) studied feces of different species of reptiles in a serpentarium of the city of Puebla, finding 7.77 % of Salmonella isolates. Likewise, Silva-Hidalgo et al, (2012) reported the presence of this bacterium in 11.6 % of the stool samples of captive mammals, birds and reptiles, as well as rodents and insects that live in close contact with the cages of the animals of the zoo under study; finding the serotypes Sandiego, Oranienburg, Weltevreden, Braenderup and Derby. The intraserotype analysis using PFGE showed indistinguishable strains (no genetic diversity), with some isolated exception, which suggests the circulation of this variant of Salmonella among the animal inhabitants in these environments, which can be disseminated through water, food, fomites or vectors like waterfowl and rodents.…”

Salmonella, climatic change, Mexico, biofilms, antimicrobial resistance, genetic diversity. línea, 2) habilidad para utilizar fuentes alternas de carbono, y 3) capacidad de formar biopelículas. El uso de alguna estrategia o la combinación de ellas por las poblaciones de Salmonella circulantes podría aumentar el riesgo para la salud de la población. Por ello, esta revisión tiene como objetivo analizar de manera exhaustiva los elementos que le confieren una mayor capacidad de adaptación, favoreciendo las dinámicas de dispersión de Salmonella, y contribuyendo de esta manera al entendimiento de su naturaleza y a la epidemiología debida a este patógeno en México. Introducción Salmonella es mundialmente reconocida como el principal agente etiológico de enfermedades transmitidas por alimentos y agua (WHO, 2018a). El centro para el control y prevención de enfermedades de los Estados Unidos de América y la autoridad Europea de Seguridad Alimentaria reportan anualmente más de 1,000,000 y 100,000 infecciones por Salmonella no tifoidea, respectivamente (CDC, 2018a; EFSA, 2015), mientras en México el número alcanza alrededor de 70,000 casos de este padecimiento cada año (DGE, 2017). A pesar de que esta bacteria reside predominantemente en el tracto gastrointestinal de animales de sangre caliente y de sangre fría, su reconocida ubicuidad en ambientes naturales, donde despliega estrategias de supervivencia, le permiten prevalecer por periodos prolongados en suelos y sedimentos adaptándose a condiciones estresantes de temperatura, pH, desecación, estrés osmótico y nutrimental, así como depredación, facilitando su supervivencia, dispersión ambiental y alcance de nuevos hospederos
