Smallpox as an actual biothreat: lessons learned from its outbreak in ex-Yugoslavia in 1972.

Variola (smallpox) virus is classified as class A of potential biological weapons, due to its microbiological, genetic, antigenic and epidemiological characteristics. The potential danger is more real because vaccination against smallpox has stopped since disease eradication in 1979. That is why we want to share our unique, rich experience and acquired knowledge in the fight against this highly contagious and deadly disease during the smallpox outbreak in ex-Yugoslavia in 1972.

Antimicrobial susceptibility and β-lactamase production in Bacillus cereus isolates from stool of patients, food and environment samples.

Background/aim: Bacillus cereus (B. cereus) usually ingested by food can cause two types of diseases: vomiting due to the presence of emetic toxin and diarrheal syndrome, due to the presence of diarrheal toxins. Systemic manifestations can also occur.

Prevalence of Panton-Valentine leukocidin genes in community-associated methicillin-resistant Staphylococcus aureus in the District of Pomoravlje.

Background/aim: Community-associated methicillin-resistant Staphjlococcus aureus (CA-MRSA) strains appear to have rapidly disseminated among population in the community without established risk factors for MRSA worldwide. Panton-Valentine leukocidin (PVL) is a cytolytic toxin, encoded by the lukF-PV and lukF-PV genes. PVL may be the key toxin responsible for enhanced virulence of CA-MRSA.

Seroprevalence of Borrelia burgdorferi in occupationally exposed persons in the Belgrade area, Serbia.

Lyme disease (LD) is a natural focal zoonotic disease caused by Borrelia burgdorferi, which is mainly transmitted through infected Ixodes ricinus tick bites. The presence and abundance of ticks in various habitats, the infectivity rate, as well as prolonged human exposure to ticks are factors that may affect the infection risk as well as the incidence of LD. In recent years, 20% to 25% of ticks infected with different borrelial species, as well as about 5,300 citizens with LD, have been registered in the Belgrade area.

A case of human monocytic ehrlichiosis in Serbia.

Introduction: Ehrlichiosis is a bacterial zoonosis transmitted by hematophagous arthropods--ticks. In humans, it occurs as monocytic, granulocytic, and ewingii ehrlichiosis. Pathological process is based on parasitic presence of Ehrlichia organisms within peripheral blood cells--monocytes and granulocytes.

[Therapy of chronic hepatitis C--virologic response monitoring].

Background/aim: Virological testing is considered to be essential in the management of hepatitis C virus (HCV) infection in order to diagnose infection, and, most importantly, as a guide for treatment decisions and assess the virological response to antiviral therapy. The aim of this study was to determine the rate of a sustained virological response (SVR) and various factors associated with response rates in chronic hepatitis C infected patients treated with peg interferon alpha (PEG-INF) and ribavirin (RBV) combination therapy.

Methods: A total of 34 patients, treated with PEG-IFN and RBV were studied.
