ABSTRACT
Vulvovaginal candidiasis, involving the vulva and vagina of women, is a frequent condition that causes physical and psychological distress to the individual involved. This disease is mostly caused by Candida albicans. This study assessed the incidence of candidiasis among single and married women of different age groups. Hundred (100) samples were collected and analyzed. The identification and confirmation of Candida was done based on culture, microscopy and biochemical tests. 30(54.5%) were infected with candidiasis among the single women and 25(55.5%) were infected among the married women out of the number examined from singles (55) and from married (45). Among the different age groups, women aged between 23 - 27 years presented the highest level of infection of 13(41%) out of the 32 samples examined from this age group among the single women and 11(73%) out of the 15 samples examined from this age group among married women. The lowest infection rate was seen among single women aged 33 years and above with a percentage of 100% (2 positive samples) out of the 2 women examined from this age group. Among the married women, the lowest infectiob rate was observed among those aged between 18 and 22 years with a percentage of 50% (1 positive sample) out of the 2 samples examined. This study shows that the incidence of Candida albicans infection in women is quite high and can be reduced if improved personal hygiene and adequate medical services are available.

CHAPTER ONE
INTRODUCTION
The Candida albicans infection is a yeast infection of the mouth,
skin and urogenital tract of men and women, young and old. It is the genus
mostly incriminated in candidiasis of the urogenital tract. Other species of Candida incriminated in this disease
condition are Candida tropicalis, Candida stellatoides, Candida
parapsilosis and Candida crusei. According to report of the Centre
for Disease Control and Prevention, in 2001, there are more than twenty (20)
species of genus Candida that can cause infection in humans.
The distribution of Candida albicans is widely seen in normal and
healthy individuals, and is usually found in mouth, gastrointestinal and
urogenital tracts of females where they exist as normal flora. Yeast infections
usually occur in warm and moist parts of the body (Berual et al., 1996).
It flourishes in individuals with high blood sugar (Sobel, 2007), and
can also be found in other dark areas of the body. Clothing that is too tight
or made of nylon materials that can trap heat and moisture may lead to yeast
infection (Pappas, 2006). Other predisposing factors such as pregnancy,
diabetes, broad spectrum antibiotics therapy administration of corticosteroids
or immunosuppressive drugs, drug addiction and immunological deficiencies
support the growth of Candida (Priotta and Garland, 2006). Besides,
systematic conditions such as vitamin B deficiency, hypothyroidism and
lymphoblastoma favours Candida infection (Morgan, 2005; Pfaller and
Diekema, 2007). From the fore going, it is evident that the treatment of other
infections with broad spectrum antibiotics increases the number of persons
habouring Candida in their intestine, vagina and perianal sites (Morgan,
2005; Hidalgo, 2013). The effect of antibiotics on proliferation of Candida is
based on the fact that these drugs militate against susceptible microflora
antagonistic to the fungi (Cheesebrough, 1991), thereby enhancing their growth.
Traumatic ulceration, postoperative situations, malnutrition, malignancy and
anemia also predisposes Candidiasis.
Candida albicans infection manifests in
different parts of the body. In the vagina are found itching, redness and a
thick white vaginal discharge with occasional white patches on the skin of the
vaginal area. The irritation from vaginal Candidiasis is responsible for the physical discomfort
experienced by some patients. The offensive vaginal discharge is a product of
organic decomposition of the proteinous component on the vaginal mucosa.
Vaginal Candidiasis of
pregnant women may occur as mild vaginal infection and may not be connected
with infection of the anus.
Vaginal and vulva Candidiasis
is also found at high frequency among sexually active people hence,
the choice of age brackets under study. Accordingly, as a girl matures,
hormonal changes takes place making them more vulnerable to Candida infection
(Onianwah, 2014)
Prevention of Candidiasis can be by employing the use of
unscented bath soaps, lotions, laundry detergents and gels. It is suggested
that less fragrance free bath and cleansing products can be used (Cheesbrough,
1991).
This research focused on the incidence of Candida albicans infection
(candidiasis) of the urogenital tract of single and married females of
different age groups.
1.1
AIMS AND OBJECTIVES OF THE
STUDY
Aim: To evaluate the incidence of Candidiasis among single and
married women of different age groups that attends Federal Medical Centre,
Umuahia.
Objectives of the study are:
· To isolate the causative
agent of the disease
· To identify the causative
agent of the disease
· To determine the level of
occurrence of the disease among single and married women of different age group
patients.
1.2 SCOPE OF STUDY
This research work is
limited to only single and married women of different age groups attending
Federal Medical Centre, FMC, Umuahia, Abia State. The work was carried out with
necessary specimens such as early morning urine, high vaginal swab samples,
which were collected from the women.
1.3 STATEMENT OF
PROBLEM
Candidiasis has caused a
lot of problem in our society because of the nature of what the disease looks
like. It brings about discomfort such as itching, which causes a lot of
embarrassment to people publicly. Secondly, candidiasis cause frequent
urination in people that are suffering from the disease and such people will
not find it easy to stay in public for a long time without being disgraced by
this infection. Another problem with this infection is that when it stays long
in the body it will make the person that is suffering from it to develop body
odour due to severe discharge.
