Epidemiological characteristics of salmoneilosis in Vojvodina

Abstract

During this period there were 26,851 cases of salmonellosis (mean annual incidence of 51.1/100,000 and mean annual mortality of 0.9/100,000). Mean annual case fatality ratio during this period was 0.1%. The specific incidence was highest in 12-24 month-old children (251/100,000), and lowest in the oldest age group (13.9/100,000). Lethality was highest in children younger than 1 year, and persons older than 50 years (84%). The number of cases registered in food-born epidemics makes 41.7% of all registered cases. A mayority of 772 registered epidemics were small epidemics among families, relatives and friends. The great epidemics with large number of infected persons were due to an industrial bakery with 1713 ill persons and a public restaurant with 311 ill persons during the 80's. An epidemic was due to sandwiches from an industrial bakery distributed through the whole territory of Vojvodina with the highest incidence of salmonellosis in 1987 (137.7/100,000). The most common serotype was S. Enteritidis (69.7%), but 68 more serotypes were isolated. The most common cause of epidemics were eggs and egg products (76.2%). Salmonella spp. was isolated from food in small number of epidemics (less than 20%), because epidemics were discovered usually 2 or 3 days after their beginning.

Epidemiological characteristics of the most common zoonoses in the central Banat district of Vojvodina from 2002 to 2016

“…Homemade cakes and cookies consumed among family members were the most prevalent source of infection in the 28 outbreaks of human Salmonellosis in the CBDV. This is quite similar to the findings of the Belgrade study where 63.4% out of total outbreak cases of human Salmonellosis were registered after some family celebrations [41], as well as to the results obtained from other parts of APV [7]. Surprisingly, only 15% out of total human Salmonellosis cases were detected during the outbreak occurrence and the majority of Salmonellosis infections were classified as sporadic cases.…”

“…A mandatory notification of Salmonellosis in the APV has been introduced since 1976. During the last 25 years of the XX century, there were several epidemics of human Salmonellosis that were registered mainly after eating improperly cooked contaminated foods [6,7].…”

Clonal Spread of Salmonella enterica Serovar Infantis in Serbia: Acquisition of Mutations in the Topoisomerase Genes gyrA and parC Leads to Increased Resistance to Fluoroquinolones

“…Infantis has been reported, but isolates differ genetically and phenotypically from strains isolated some years ago (Gal‐Mor et al., ). In Serbia, epidemiological data imply that food poisoning caused by Salmonella is most often linked to home‐made meals resulting in small family epidemics (Petrović et al., ).…”

Epidemiological characteristic of salmonellosis in Serbian areas of Kosovo and Metohija

“…U period od 13 godina u srpskim sredinama Kosova i Metohije zabelezeno je ukupno 11 epidemija, samo kod 2 epidemije imamo utvr en put prenošenja uzro nika infekcije, u prvom slu aju to je bila torta služena u krugu porodice I u drugom kontakt (dokazano kliconoštvo). Prema našim podacima najve i broj epidemija se desio u doma instvima(.porodica,,porodi na slavlja), što je u saglasnosti sa rezultatima u Francuskoj gde je ve ina registrovanih epidemija salmoneloza bila povezana sa ishranom kod ku e.I u centralnoj Srbiji tokom 2002.godine najve i broj salmoneloza bile su porodi ne epidemije (8)…”
