ABSTRACT
Objectves: The purpose of this study was to isolate and identfy Candida spp. and Saccharomyces
spp. from bakery products (bread and cake) using a range of cultural (e.g., colony shape, size,
color, elevaton, surface edge, consistency, etc.) and morphological (e.g., cell shape, bud, etc.)
features.
Materials and Methods: Cake and bread samples (n = 40) were obtained from various retail out-
lets in Bangladesh Agricultural University (BAU), Mymensingh. The samples were collected asep-
tcally and transferred to the Department of Microbiology and Hygiene at BAU, Mymensingh, for
analysis. Processed samples were inoculated onto Potato Dextrose Agar media and incubated at
a humidity of 75% for 5-7 days at 28°C. The fungi were primarily identfed based on their colony
structures. DNA was extracted from suspected colonies and was used for the detecton of Candida
spp. and Saccharomyces spp. using genus-specifc primers (ITS-1 and ITS-4).
Results: Candida spp. and Saccharomyces spp. had a combined prevalence of 50% (n = 20/40; p
< 0.05). Candida spp. was identfed in 15% (n = 6/40) of the fungi, while Saccharomyces spp. was
detected in 35% (n = 14/40).
Conclusion: In conclusion, it can be stated that bakery foods have a signifcant impact on human
fungal infecton in Bangladesh.

Introducton
A bakery (also known as a baker’s shop or bake shop) is
an establishment that manufactures and sells baked goods
made with flour, such as bread, cookies, cakes, pastries, and
biscuits. Bangladesh’s bakery foods culture has swept the
country. Bangladesh’s bakery food business is a fast-rising
sector. Bakery food is becoming a popular and significant
source of nutrition for families of all economic classes in
Bangladesh. Candida spp., Aspergillus (A.) flavus, A. fumiga-
tus, A. niger, Penicillium spp., and Fusarium spp. are the most
common food contaminating fungi [1]. These are respon-
sible for about 90% of food poisoning worldwide. In most
cases, contamination occurs due to inappropriate handling,
unclean preparation conditions, and infected utensils [2,3].
Yeasts (Candida spp. and Saccharomyces spp.) are
unicellular, eukaryotic, polyphyletic, and ubiquitous
microorganisms that are found on a wide variety of fruits,
vegetables, bakery foods (e.g., bread, cake, etc.), and other
plant materials [4]. The prevalence and characteristics of
superficial fungal infections (SFIs) vary by age, gender,
climatic conditions, lifestyle, and patterns in population
migration. Subcutaneous fungal infections of the skin are
frequent in rural areas of Bangladesh [5].
Bread is one type of bakery item that is suspected of
causing yeast infections. Numerous infections, including
oral thrush, vaginitis, urinary tract infection, endocardi-
tis, respiratory syndromes, and meningitis, are caused by
Candida spp. [6]. Candida spp. and Saccharomyces spp.
have become substantial causes of illness and mortality in
patients undergoing immunosuppressive chemotherapy
for cancer or organ transplantation, as well as in immuno-
compromised patients, such as those with untreated AIDS.
Children and the elderly are more prone to oral candidiasis
