Abstract

A study of current resistance to antibiotics was conducted in 500 strains of Staphylococcus aureus isolated from ewes with clinical and latent mastitis, from sheep milk and products made from it (sheep lumpy cheese, bryndza cheese). A diffusion disk method was used to assay 14 kinds of antibiotics (AMP, BAC, CEF, ERY, GEN, CMP, KAN, LIN, OXA, PEN, RIF, SPI, VAN, TET) and one chemotherapeutic drug (COT). The highest resistance was observed in the cases of clinical mastitis (from 8% and 10% in COT and KAN to 68% and 69% in PEN and TET). Resistance significantly decreased in 13 kinds of antibiotics in the group of cases with latent mastitis (from 3% in SPI to 30% in PEN), it increased in KAN (13%) and COT (12%) only. Resistance also decreased in bulk samples of sheep milk; it was the highest in PEN (27%) and AMP (17%) and the lowest in CEF, RIF and SPI (5%). Sheep lumpy cheese and bryndza cheese are mostly made from unpasteurized milk. Resistance continued to decrease even in these dairy products. It ranged from 2% in CEF to 16% in OXA in sheep lumpy sugar, while it varied from 0% in SPI to 14% in TET in bryndza cheese. The results demonstrate that sheep milk and products made from it are not any important sources of antibiotic re...Continue Reading

Allergy & Infectious Diseases

Allergies result from the hyperreactivity of the immune system to some environmental substance and can be life-threatening. Infectious diseases are caused by organisms including bacteria, viruses, fungi and parasites. They can be transmitted different ways, such as person-to-person. Here is the latest research on allergy and infectious diseases.

Antimicrobial Resistance (ASM)

Antimicrobial resistance poses a significant threat to the continued successful use of antimicrobial agents for the treatment of bacterial infections.

Antifungals (ASM)

An antifungal, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis, cryptococcal meningitis, and others. Discover the latest research on antifungals here.
