“…In China, a prevalence of approximately 20% was reported in cattle sampled at multiple abattoirs and it was postulated that the feces and the hides posed a high risk for contamination with Salmonella [ 13 ]. Yang [ 25 ] found 13 Salmonella isolates from 78 pieces of beef in marketplaces in Shaanxi and Xu [ 26 ] reported the prevalence of Salmonella in beef increased recently (9.30–15.79%) in southern China. The high prevalence of Salmonella in feces in this research may be related to the place of origin.…”

The objective of this study was to estimate the fecal carriage of Salmonella spp. among culled adult dairy cows presented to an abattoir in Wuhan, China and to evaluate their antimicrobial resistance profiles. Rectal swabs from 138 culled cows were cultured. Laboratory analysis involved the identification of Salmonella, the susceptibility assessment and the presence of Extended Spectrum β-lactamases and mcr genes in the isolates. An overall prevalence of Salmonella of 29.0% was recorded with 63.4% (26/41) and 2.4% (1/41) of the isolates identified as S. Typhimurium and S. Dublin, respectively. The occurrence of Salmonella was higher (odd ratios: 3.3) in culled cows originating from the northeast zone of China than cows originating from the central and north zones. Twenty multi-drug resistant strains (resistant to three or more antimicrobial agents) were detected (48.8%) and overall, a high resistance to ampicillin (36/41) and tetracycline (15/41) was observed. Extended Spectrum β-lactamases phenotypes were found in 7/41 isolates, of which all contained the blaCTX-M resistance gene, and no mcr genes were found by polymerase chain reaction. The high prevalence of Salmonella fecal carriage and antimicrobial resistance may contribute to an increased risk of Salmonella transmission to food.

“…To date, more than 2600 Salmonella serotypes have been reported, among which S. Enteritidis and S. Typhi are the most common [5]. S. Enteritidis infection is generally self-limiting, but patients can present with severe manifestations,and these patients should receive antibiotics therapy.…”

“…Therefore, identifying other parameters correlated with the diagnosis, severity and outcome of S. Enteritidis and clarifying the antibiotic resistance status of S. Enteritidis are imperative. In recent years, because of the abuse of antibiotics, high proportions of S. Enteritidis isolates have been reported to be resistant to multiple antibiotics [5], resulting in increasingly challenging S. Enteritidis treatment. The gold standards for S. Enteritidis diagnosis and antimicrobial susceptibility analysis rely on fecal/blood cultures, but these processes are time-consuming.…”

Aims Salmonella enterica serovar Enteritidis (S. Enteritidis) infection is one of the main causes of foodborne illness among individuals in the military. In this study, we aimed to investigate indicators associated with the diagnosis, severity and outcome of S. Enteritidis infection, and to analyze the antimicrobial susceptibility of the isolated S. Enteritidis strains.Methods Routine stool test, fecal occult blood tests (FOBTs), routine blood tests and blood biochemical analyses were completed in our clinical laboratory. The stool samples were inoculated on Salmonella Shigella (SS) agar plates, the single bacterial colony was identified with mass spectrometry (MS). The serum agglutination test was performed to identify the Salmonella serotype. Antimicrobial susceptibility testing was performed using the minimal inhibitory concentration (MIC) method with the VITEK 2 COMPACT analyzer.Results Recently, 6 patients from one company visited our department complaining of fever, watery stool, abdominal pain and so on. The patients’ white blood cell (WBC) counts (66.7%), neutrophil percentages (100%), C-reactive protein (CRP) levels (100%), prothrombin times (PTs, 100%) and serum D-dimer concentrations (83.3%) were higher or longer than normal, while serum iron (100%) and prealbumin (83.3%) were lower than normal when they were admitted. Stool cultures and serovar identification results indicated S. Enteritidis infection. The antimicrobial susceptibility results showed that the 6 isolated bacterial strains were sensitive to trimethoprim-sulfamethoxazole and levofloxacin, and resistant to ampicillin. All patients were administered levofloxacin accompanied by rifaximin and probiotics, and their symptoms and the abovementioned parameters were recovered. During the disease course, the prolonged PT, elevated D-dimer and decreased serum iron were positively correlated with severe symptoms and serum inflammatory indexes.Conclusion Prolonged PT, elevated D-dimer and hypoferremia were associated with the diagnosis, severity and outcome of S. Enteritidis infection, and a decreased prealbumin level was associated with the diagnosis of S. Enteritidis infection. In patients complaining of acute fever, watery stool and abdominal pain, PT, D-dimer，prealbumin and serum iron should be monitored to attain an early diagnosis and initiate appropriate treatment for S. Enteritidis infection.

“…Este microrganismo pode causar salmonelose também em humanos, e é categorizada como uma importante zoonose em saúde pública. Isolados de Salmonella multirresistentes com alta adaptabilidade, têm sido responsáveis por muitos surtos de doenças transmitidas por alimentos (Xu et al, 2020). A infecção pode ser adquirida por contato direto e indireto com os animais.…”

“…Evidenciando diferenças regionais quanto ao perfil das Salmonellas resistentes Kumari et al (2013) citam, por exemplo, a alta sensibilidade a anfotericina B e ao cloranfenicol em seus isolados. Xu et al (2020) pontuam que a análise de risco do sistema de pontos críticos de controle (HACCP), para toda a cadeia alimentar de varejo de carne, deve ser analisada e melhorada a fim de evitar-se a contaminação cruzada na comercialização dos alimentos. Importante também que o monitoramento "presença-ausência" seja feito não somente por métodos moleculares (riscos de falsos positivos) mas também seja confirmado pelos métodos tradicionais de bacteriologia.…”

A salmonelose aviária é um termo usado para se referir aos três tipos diferentes de doenças bacterianas causadas pelo gênero Salmonella sp (pulorose, tifo aviário e paratifo aviário) nas aves domésticas. A pulorose tem sua etiologia relacionada à Salmonella pullorum, o tifo aviário à Salmonella gallinarum e o paratifo aviário a todos os demais sorotipos patogênicos entéricos. As três doenças podem acometer aves domésticas de qualquer idade causando sinais clínicos inespecíficos e sistêmicos, com quadros agudos e crônicos que podem ser confundidos com outras bacterioses. Mundialmente disseminadas, essas doenças são responsáveis por causar impactos na economia brasileira e na saúde pública. A transmissão pode ocorrer pela via vertical e horizontal e pelo contato indireto com alimentos, água de beber, vetores e fômites contaminados. O diagnóstico das aves doentes pode ser realizado com base no histórico, sinais clínicos, achados anatomopatólogicos e exames laboratoriais que incluem a identificação dos agentes por meio de isolamento bacteriano, soroaglutinação rápida em placas, soroaglutinação lenta em tubos e reação em cadeia da polimerase (PCR). Como não há tratamento antibiótico que elimine completamente a infecção nas aves as medidas de controle e prevenção são indispensáveis no controle. O presente artigo trata-se de uma revisão de literatura e tem como objetivo conhecer o referencial teórico referente à doença e aos seus agentes, além da possibilidade de esclarecer a importância da prevenção e do controle desse microrganismo, devido ao caráter infectocontagioso e zoonótico da doença, que pode causar inúmeros prejuízos econômicos e impactos negativos para a saúde pública.
