The effect of feeding frequency on the growth and feed efficiency of Heterobranchus bidorsalis was investigated at two feeding rates (10% and 40% of body weight) in a 2x2 factorial experiment. The study was conducted in twelve 2x2x1m outdoor concrete ponds supplied with aeration with three replicate ponds for each treatment. Fish averaging 80 ± 4.5 mg were fed either two times or four times daily at two different feeding rates using practical diets for ten weeks. The percentage weight gain ranged from 55.25% to 95.13%.

The nematode specimens from Clarias species were confirmed to be the larval forms of nematode Eustrongytides africanus that occurs in a wide diversity of fish-eating aquatic animals. And its effective third- and fourth-stage larval development was also described. The physical presence of this parasite in Clarias species is manifested by swellings or undulations on skin surfaces as grub-like.

This breeding experiment is divided into three trial groups. The first trial group consist of 2 males and 3 females Clarias gariepinus which were injected with a calculated amount of synthetic hormone (Human chronic Gonadotropin) according to their measured weight. In the second trial group, there are also 2 females and 3 females C. gariepinus which were injected with a calculated amount of natural hormone (Pituitary extract). The third trial group consist of 2 males and 3 females C. gariepinus which were not injected with anything and therefore serves as control.

It has been increasingly recognized that enteric protozoan parasites are important in immunocompromised individuals. These pathogens tend to aid disease progression or otherwise in such individuals. The association between intestinal parasites and HIV seropositive subjects in IDH was evaluated using fresh stool samples from 106 patients and 3op controls. Samples collected included both male and female in age ranges of 15-50. Stool samples were examined microscopically for consistency, presence of blood, mucus and adult worms.

This study aims at documenting the awareness, approach and use of contraception amongst women and female youths in Mararaba, Nasarawa State, Nigeria. 100 respondents; 60 female youths and 40 women aged within 18-45 years were cross-examined using a structured questionnaire and informal dialogues. Data gathered were analyzed using appropriate statistical tools. Results show that respondents between ages 23 and 27 (female youths and young married women) attending higher institutions were most represented in this study.

The markets in Benin City are currently ‘saturated’ with processed powdered foods from several sources which include wheat, maize, tubers et cetera. The demand for these products are also on the increase. It was against this background that ten adult powdered foods were purchased from the open markets in Benin City to evaluate their nutritive values. Consequently, the proximate analysis of the foods was determined. Additionally, the micro- and macro- mineral contents were determined with the AOAC and AACC methods.

Trypanosoma brucei, a causative agent of trypanosomiasis in livestock also possesses the ability to reoccur in disease conditions thereby increasing the trouble of ill health and if not treated on time could cause great losses to man. A comparative study was carried out to investigate the efficacy of different fractions of the extracts of Terminalia avicennoides and Bombax buopodezense on Trypanosoma brucei brucei infected wistar rats. The plants extract were fractionated using different solvents by chromatography technique.

Radiology unit is one of the commonly used diagnostic centres in the hospital. Medical devices in this unit harbour nosocomial pathogens that may likely complicate patient illnesses. This study investigated the presence of pathogenic microbes in usable equipment from hospital radiology units. Samples were collected via sterile swab stick from three radiological units (Ultrasound, X-ray and Mammogram rooms) equipment of the University of Benin Teaching Hospital, Benin City. The media used in the isolation of the microorganisms were Nutrient Agar (bacteria) and Potato Dextrose Agar (fungi).

This study was carried out to determine the effect of temperature on radial growth phase of Aspergillus spp. Aspergillus niger was isolated from apparently spoilt samples of onion, tomato and carrot. These food samples were obtained from different locations. Isolation of A. niger was done using Potato Dextrose Agar (PDA). A. niger which was inoculated at the centre of the PDA plate was observed for radial growth for a period of seven days at 12 hourly interval, twice daily at 280C and 370C respectively. It was generally observed that A.

Monitoring pathogen survival in polluted environmental media is useful as an early warning tool to forestall outbreaks of infections and safeguard public health. Survival of clinical strains of Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Salmonella typhi and Vibrio cholerae was monitored for 192 hours in pre-sterilised samples of domestic wastewater and sediment, agricultural wastewater and river water.
