Drug resistance and virulence traits of Acinetobacter baumannii from Turkey and chicken raw meat.

Acinetobacter baumannii (A. baumannii) is a miscellaneous bacterium with ability of extensive antibiotic resistance. A. baumannii strains have also been isolated from animal origins. The objective of our atudy was characterization of A. baumannii antibiotic resistance and virulence traits from turkey and chicken raw meat. Of 576 turkey and 424 chicken specimens during 2017-2019, 200 (120 from turkey and 80 from chicken) isolates were identified as A. baumannii. Virulence factors and antibiotic resistance patterns of A. baumannii were determined using polymerase chain reaction (PCR) technique and Kirby-Bauer test. All the isolates were resistant to tetracycline and cefoxitin and 81 % and 56 % of them produced ESBLs and carbapenemases. Also 74 % of them (34 % from chicken and 40 % from turkey) were multidrug-resistant (MDR) A. baumannii. Colistin and fosfomycin non-susceptibility was detected among 12 % and 10 % of them, respectively. The existence of tetA, dfrA, tetB, blaoxa-51-like, blaoxa-23-like, sul1, blaoxa-24-like, blaoxa-58-like, fosA3 and mcr-1 genes accounted for 80 %, 71 %, 70.5 %, 66 %, 62 %, 43 %, 34 %, 22 %, 11 % and 13 % of them, repectively. Additionally, predominant virulence factors included the fimH, afa/draBC, sfa/foc DE, cnfI and cnf2 genes. The rate of antibiotic resistance genes and virulence factors was not significantly different between turkey and chicken (p > 0.05). High rate of antibiotic non-susceptibility even against last-line resorts in poultry products is a concern and suggest that animals play a potential role as reservoirs of transmission of MDR A. baumannii.

Zataria Multiflora bois as an auspicious therapeutic approach against Echinococcus granulosus: Current status and future perspectives.

Hydatidosis caused by Echinococcus granulosus is a major zoonotic diseases. In addition to imposing heavy economic losses, the disease is a public health problem worldwide. The larval stage of the parasite (hydatid cyst) is formed in a wide range of domestic, wild and human beings as intermediate hosts. On the other, its recurrence has been reported anywhere as a reemerging disease. Although the cysts have some evading mechanisms, both human TH1 and TH2 cells subsets are stimulated. Because of increasing resistance and adverse effects of medications such as abnormalities of liver and other organs functions and abdominal pain, seeking alternative therapeutic approaches to be inexpensive, easy available, with low side effects and toxicity seems essential. However, the lack of information on the social and economic welfares of herbal medicines for the industrial scale application is a limitation. Zataria Multiflora bois (ZMB) has exhibited huge advantages and tremendous protoscolicidal effects as demonstrated by numerous studies and its combination therapies with anti-parasitic drugs have exerted desirable outcomes in vitro and in vivo. Noticeably, the compound confers negligible side effects or toxicity even at high concentrations. ZMB has exhibited promising inhibitory effects against hydatid cyst, particularly when combined with chemical drugs and in formulations of nanoemulsions. Its immunomodulatory effects include increase of nitric oxide production (NO) and protection of hepatic cells (Kupffer cells, fat-storing cells, and endothelial cells), enhancement of macrophages and T cells and increase of cytokines production. This study aimed at assessment of ZMB traits for application against hydatid cyst protoscolices.
