Abstract

Bee colonies are exposed to a wide variety of actions of the agricultural ecosystem and to a multitude
of variations of the environment throughout the year. All these factors can affect the bees’ microbial balance. This study aimed to determine the microflora of bee families before the wintering period. The bees for the research were randomly collected at two apiaries of 17 and 24 bee families. Under laboratory conditions, insemination was performed on common, selective and differential growth media using material of the bees’ intestines. As a result of the investigations, an intensive growth of bacterial colonies was noticed on all microbial culture media. They were predominantly formed by different forms of bacteria such as streptococci, staphylococci, E. coli, Salmonella and microscopic fungi. Most colonies of microorganisms developed on Endo and Peptonate Agar media, being represented by the microbial colonies of E. coli and streptococci, respectively.
Key words: Honey bees; Intestinal microflora; Nutrient media; Microbial colonies.
Rezumat. Coloniile de albine pe tot parcursul anului sunt expuse la o varietate largă de acțiuni ale ecosistemelor agricole și la o multitudine de variații ale mediului, care le pot afecta echilibrul microbian. Studiul de faţă îşi propune de a stabili varietatea microflorei familiilor de albine înaintea perioadei de iernat. Albinele pentru cercetare au fost colectate în mod aleatoriu de la două stupine, cu 17 şi 24 de familii de albine. În condiții de laborator, din intestinele albinelor au fost efectuate însămânțări pe medii nutritive obișnuite, selective și diferențiale. În rezultatul investigațiilor s-a stabilit o creștere intensivă de colonii bacteriene pe toate mediile microbiene nutritive. Acestea au fost constituite preponderent din formele bacteriene precum streptococi, stafilococi, E. coli, salmonele și fungi microscopici. Cele mai multe colonii de microorganisme s-au dezvoltat pe mediile Endo și Agarul peptonat, fiind reprezentate de coloniile microbiene E. coli și, respectiv, streptococi.
Cuvinte-cheie: Albine melifere; Microfloră intestinală; Medii nutritive; Colonii microbiene.
