RESUMO
OBJECTIVE: Iron Deficiency Anemia (IDA) is common nutritional deficiency particularly in women and also common during the older age. Aging increases plasma levels of inflammatory mediators such as pro-inflammatory cytokines and acute phase proteins. However, there is little information about changes in antimicrobial proteins in elderly women with IDA. In this study, we aimed to determine the changes in pro-inflammatory cytokines and newly discovered antimicrobial proteins like hepcidin, chemerin and defensin in elderly women with IDA. METHODS: Blood samples taken from healthy 20 women (55±7 years old) and 20 women with iron deficiency anemia (58±6) were used as material of the study that came to the Cankiri State Hospital in 2016 and 2017 years. RESULTS: In the study, plasma C-Reactive Protein (CRP) (P <0.01), tumour necrosis factor-α (TNF-α) (P <0.05) and interleukin-6 (IL-6) levels (P <0.05) were significantly increased in group with IDA when compared with healthy group. Also plasma hepcidin (P <0.001), chemerin (P <0.05) and defensin levels (P <0.05) were determined significantly higher than the healthy group. CONCLUSION: We found that inflammatory changes occur in elderly women with IDA. Besides pro-inflammatory cytokine levels (CRP, IL-6, TNF-α), antimicrobial protein levels (hepcidin, chemerin, defensin) were found higher in elderly women with IDA because of inflammatory changes.
RESUMO
The aims of this study were to determine the existence of pvl gene, some toxin genes, and mecA gene in Staphylococcus aureus strains isolated from sheep milk and to examine antimicrobial resistance profiles in staphylococci from sheep and goats' milk. The milk samples were collected from 13 different small ruminant farms in Kirikkale province from February to August 2009. A total of 1,604 half-udder milk samples from 857 ewes and 66 half-udder milk samples from 33 goats were collected. Staphylococcus spp. were isolated and identified from the samples. Toxin genes and mecA gene among S. aureus strains were determined by PCR. Antimicrobial susceptibility of staphylococci was examined by the disk diffusion method on Mueller-Hinton agar, and interpreted according to the Clinical Laboratory Standards Institute (CLSI) guidelines. The prevalence of subclinical intramammary infection in both ewes and goats was 5.2%. The most prevalent subclinical mastitis agents were coagulase-negative staphylococci and S. aureus with prevalences 2.8% (n:46) and 1.3% (n = 21), respectively. The prevalence of resistances in isolated Staphylococcus spp. to penicilin G, tetracycline, erythromycin, gentamicin, and enrofloxacin were found as 26.9% (18), 7.5% (5), 6.0% (4), 3.0% (2), and 1.5% (1), respectively. Only 3 of the 21 S. aureus ewe isolates (13.4%) were shown to harbor enterotoxin genes being either seh, sej or sec. However, fourteen (66.6%) of the 21 S. aureus isolates had pvl gene while none of the isolates harbored mecA gene. In conclusion, Staphylococci were shown to be the most prevalent bacteria isolated from subclinical mastitis of ewes and goats and these isolates were susceptible to most of the antibiotics. In addition, S. aureus strains isolated from ewes were harboring few staphylococcal enterotoxin genes. However, Panton-Valentine leukocidin produced by S. aureus could be an important virulence factor and contribute to subclinical mastitis pathogenicity.
