Harada-Mori culture was applied for detection. The average prevalence of S. stercoralis infection was 13.42%; 11.77% in male and 13.85% in female. The highest prevalence was found (40%) among the slum dwellers aged 50-59 years old following the age group 10-19 years (16.66%). In summer, the prevalence was the lowest (2.50%) and the peak was in rainy season (33.33%). The infestation was significant (p<0.05) depending on the educational status, economic condition and sense of hygiene among the slum residents. Noticeable prevalence was observed among the dwellers living in mud floored house (40.91%), performing irregular nail trim (50%), day laborer (31.58%) and bare footers (24.24%). Positive history of diarrhoea showed higher prevalence (18.52%) of S. stercoralis. The results of the present study suggest that, in the urban slum community, changes in the household environment, promulgation of proper hygiene knowledge amongst the slum dwellers would lessen the transmission of S. stercoralis infection. \u0000Asian Australas.

Colibacillosis in commercial broiler farms causes huge economic loss through a relatively high mortality and loss of production. In the present study, a total of 275 broilers of 104 farms were examined through post-mortem and among them 150 (54.55%) broiler was diagnosed as affected with any lesion of colibacillosis. The most frequent gross lesions of colibacillosis were air sacculitis (20.67%), omphalitis (12.00%), pericarditis (13.33%), perihepatitis (13.33%), peritonitis (1.33%), colisepticemia (8.00%), enteritis (8.00%) and a large number 35 (23.33%) of broiler combination of different form of colibacillosis. The microscopic lesions of these conditions were chronic passive congestion, fibrosis of liver capsule, telangiectasis, thick fibrous layer in the pericardium of heart, blunting and sloughing off villus and infiltration of lamina propria of intestine. The results obtained during the study period revealed that winter season of the year was significant (p>0.05) high risk factors of colibacillosis in broiler but litter, age, farm size, source of water were not significantly risk factor. Considering the factor it could be concluded based on pathology that colibacillosis causes high mortality and winter season was the main risk factor in broiler at Chittagong District. \u0000Asian Australas.

Then the animals was subdivided into some risk factors such as  age, sex, breed, history of umbilical infection which may be lead to umbilical hernia. It was observed that male (61.10%) were in more risk than that of female (38.90%). In case of male calves maximum occurrence of the disease were in the age group of 1-3 months (45.45%) followed by <01 month of age group (36.36%) and least occur in 3-6 months of age group (18.18%) and in case of female calves maximum occur in the age of 1-3 months (71.43%) followed by in the age group of <01 month and 3-6 months (14.29%). The occurrence of umbilical hernia was more common in crossbreed calves (77.78%) than that of indigenous calves (22.22%). In case of crossbreed animals, male calves (44.44%) were more susceptible than in female calves (33.33%). In case of indigenous animals, male and female calves (11.11%) are more or less equally susceptible to the disease. In this study other umbilical infection likes umbilical abscess and navel ill which enhance the probability of occurrence of umbilical hernia, although it may be inherited in a dominant or recessive mode. \u0000Asian Australas.

Considering easy availability and cost effectiveness, rice husk and leftover tea waste biomass were used as biosorbent for chromium (III) absorption. Through batch experiment, absorption efficiencies at different parameters (pH, chromium concentration, absorbent dosage, exposer time) were determined and measured by FAAS. The results showed that efficiencies of left over tea waste and rice husk were 87.14% and 85.71% respectively. Our study revealed that 7.5 gm/L biosorbent works best to absorb 0.5 mM chromium(III) solution under 45-60 minute exposer in room temperature at pH 4.0- 5.0. At natural condition, 72% and 78.4% chromium were absorbed from the raw tannery effluent by rice husk and tea waste respectively. FT-IR studies indicated the functional groups (O-H, C-H, C=C, C=O, C≡C and C≡N) might be involved in the sorption of Cr (III) onto leftover tea waste and rice husk biomass. The findings indicate that these biosorbents could be employed in the removal of Cr (III) from aqueous solutions and industrial effluents. \u0000Asian Australas. J. Biosci.

The experiments were conducted as a Randomized Complete Block Design (RCBD) with three replications. Twelve competitive plants were selected from the middle row of plots for data collection. Data collected include plant height (cm), stem girth (cm), number of leaves, number of branches/plant, average number of tuber/plant, average tuber length, total tuber weight/plant and yield/ha. Slight to high differences were observed between the Phenotypic Coefficient of Variation (PCV) and Genotypic Coefficient of Variation (GCV). Phenotypic variances for the characters under study were higher than genotypic variances in the years, indicating high influence of the environment which allows for the selection of character combinations and pools for genetic gain. This study revealed that indigenous cassava (Manihot esculenta) cultivars used in this experiment showed better growth responses in dry weather conditions, an indication that the cultivars posses some strains in their genetic constitution that may be useful in developing improved drought resistant varieties of cassava. \u0000Asian Australas.

Shidal is produced by natural fermentation process of fresh water punti and marine phaisha and poa fish during winter (October to January). It was found that the Shidal production from freshwater fish in Lalpur has been shrinking gradually due to a decline in fish production from the Meghna River Basin and low supply of raw fishes from others areas. The fishers noted the local extinction of large numbers of once common fish with a gradually low supply of punti and a declining average size among the fishes that are still captured. It was found that not only the total volume of catch decreased but there have been a marked decline in catch per unit effort (CPUF) over the last ten years. During the fermentation season, every day 2-4 ton of raw punti are sold in Lalpur Fish Landing Center and the price of punti varies with grade, season and quality.  On an average 4 kg of fresh punti produces 1.2 kg of dry punti and 1.2 kg of dry punti produces 1.44 kg of shidal. It was observed that there were two types of punti used for making shidal in Lalpur - with scales and without scales. The prices of shidal were Tk 800/kg, Tk 500/kg, and Tk 500/kg produced from punti, poa and phaisha, respectively. There are nearly 250 dangaries (fish processing place) for Shidal production and each of the danagaries produce 100-150 motkas (each motka contains   36-40 kg of shidal) of shidal in a season. One motka is sold in Tk. 20,000-24,000 when there is no salt used but Tk. 16,000 per motka when salt is used. It was found that around 2000 people were employed in Shidal production and another 200 people worked in filling in the motka in Lalpur. No chemical are used to make Shidal but some salt is applied during Shidal processing. It was observed that there was no fixed marketing channel for Shidalshutki. Seventy percent (70%) of the Shidal are produced for the domestic market. Shidal produced from small sized punti are exported to India but Shidal produced from marine fishes has never been exported. Although people prefer Shidal made from punti, but due to its gradual disappearance from the natural water bodies, they are forced to consume Shidal prepared from marine poa or phaisa. \u0000Asian Australas.
