Due to issues concerning antimicrobial resistance, the use of antibiotics in poultry and pigs has been restricted in many countries. The research focus is now on suitable and readily available alternatives to antibiotic growth promoters. Alternatives such as probiotic, prebiotic, synbiotic, enzymes and acidifiers are being utilized while Phyto biotics (plant extracts) are also considered as viable alternatives. In this study, leaf extracts of Azadirachta indica (neem) and Vernonia amygdylina (bitter leaf) were administered through drinking water, while enzyme (Roxazyme G2 G ®) was  supplemented in the feed of different groups of broiler birds which were randomly allocated to three treatments and a control in triplicates of ten birds per replicate. The control group did not receive either plant extract in water or enzyme in their diet. On day 42, the chickens were slaughtered; the digesta was gently collected from the ileum and caecum for microbial analysis, while histological analysis was carried on the empty ileum for the determination of villus height. Data collected for microbial analysis was log transformed before statistical analysis and was stated as Log colony forming unit/g of digesta sample (Log cfu/g). The highest villus height was recorded for enzyme treatment (0.955mm) followed by bitter leaf (0.717mm), and least for neem leaf (0.592 mm) with 0.656 mm for the control. Enzyme supplementation, bitter leaf and neem leaf extract administration had no significant effect (p>0.05) on villus height. However,villus height recorded for enzyme supplementation and administration of bitter leaf extract was numerically higher than the control group. The population of total heterotrophic bacteria (THB) in the ileum was significantly higher (p<0.05) in the control group (9.28 Log cfu/g) than enzyme supplementation (8.52 Log cfu/g) and administration of leaf extract. The least value was recorded was recorded with bitter leaf (7.94 Log cfu/g). A value of 8.14 Log cfu/g was recorded with neem extract in drinking water. Total coliform was significantly higher (p<0.05) in the control (7.33 Log cfu/g) than in enzyme (6.00 Log cfu/g), neem leaf (4.74 Log cfu/g) and bitter leaf (4.84 Log cfu/g) treatments. The population of enteropathogenic bacteria (Escherichia coli and Salmonella) was also significantly reduced (p< 0.05) by enzyme supplementation and administration of neem leaf and bitter leaf extracts in the ileum. The THB and total coliform counts (Log cfu/g) was significantly (p<0.05) reduced by enzyme supplementation, neem leaf and bitter leaf extract in the caecum also. In conclusion, the results of the current study showed that the leaf extracts and enzyme supplementation significantly decreased the number of enteropathogenic bacteria in the ileum and caecum. Although there was no significant impact on villi height, but numerical difference in villi height were recorded.

Introduction: Access to sufficient and safe drinking water is essential for human health and welfare. Countries in the Pacific Region like Fiji frequently face issues with access to safe drinking water and supply problems. Fluctuations in water resource availability, often untreated water and faulty treatment facilities, pollution, lack of proper water management frameworks and most importantly lack of water monitoring resources are all factors that influence Pacific Island Countries. Apart from this, Pacific Islands and their water supplies are susceptible to climate hazards such as floods, cyclones and drought. The Western Division of Fiji Islands is highly prone to adverse climatic conditions; therefore regular monitoring of the various drinking water sources is essential to ensure safety of people. This study was conducted in the Lautoka to Nadi corridor where 25 sites were randomly selected for water analysis processing from January to February 2019.    Method: Physio-chemical analysis, such as measuring pH and turbidity as well as simple microbial analysis, was conducted on the water samples. Specific growth media was used to determine the different types of bacteria (Coliform, Escherichia coli and Salmonella enterica) present in the water samples; Lauryl Tryptose Broth, Eosin Methlylene Blue Agar, Xylose Lysine Deoxycholate was used. Turbidity was measured using a digital turbidity meter and pH value was determined employing a digital meter. Results and Discussion: From the analysis it was determined that overall the pH levels of samples (6.02-8.30) falls within the permissible limits; whereas turbidity was generally higher in untreated water sources with ranges from 3 to 8 nephelometric turbidity units. Microbial content was higher in untreated water samples. Other sources such as springs and creeks recorded the most significant number of Coliforms when compared to other sources and some samples indicated the presence of Escherichia coli and Salmonella enterica. Conclusion: From the study it can be concluded that all the water samples tested positive for bacterial contamination particularly Coliforms and it was higher in untreated water. Water from the Municipality had almost all physio-chemical and bacteria parameters within the World Health Organization limits, except for turbidity which was generally above 1NTU. However, this was not the case for untreated water which in some samples contained high levels of harmful bacteria. Monitoring needs to be carried out to better understand water quality and implement counter measures.

Open restaurant food vendor and consumer status as well as hygienic condition of different types of food at Dumki, Patuakhali upazila, and Kuakata union of Patuakhali district were determined. Ninety shops with 180 open restaurant food samples were collected. Among the food vendors, 97.78% were male. Maximum (68%) of them were between 21-40 years of age. The majority (54%) of them were primary educated. Half of the vending shops located on the sidewalk and one third on the footpath. The majority (81%) of the respondent had their daily net profit up to TK. 500. About 64% of vendors did not cover their food while selling; 47.78% used unclean towels and 27.78 % used plate followed by paper & polythene (49.45%) as a serving media. Everyone used tube-well water as drinking water. The few had a business permit or food-selling permit. Maximum (83.33%) consumers were male, and the highest consumers (76.667%) were aged between 21-40 years. The majority (57.77%) of consumers always consume foods on roadside. 60% of the consumers suffered from diseases. Only 4.44% of consumer had enough knowledge about nutrition and 8.89% in hygiene. About all food items contained E. coli. and salmonella. Water and salad was fully contaminated by this microorganism.

Potassium permaganate has been used since ages for disinfection of water. It is known for oxidation of cell membrane of micro organisms. But the pink colour prevailing after use makes people reject the water on aesthetic grounds. Water samples from bore wells and tap water from public places were collected from different areas of Visakhapatnam. Physio-chemical and microbial analysis analyses of the water samples were carried out. A dose based permaganate treatment of water depending upon number of colony forming units and species of microorganism present in the water was carried out [1,2,5]

AbstractThe genus Klebsiella is seemingly ubiquitous in terms of its habitat associations. Klebsiella is a common opportunistic pathogen for humans and other animals, as well as being resident or transient flora (particularly in the gastrointestinal tract). Other habitats include sewage, drinking water, soils, surface waters, industrial effluents, and vegetation. Until recently, almost all these Klebsiella have been identified as one species, ie, K. pneumoniae. However, phenotypic and genotypic studies have shown that “K. pneumoniae” actually consists of at least four species, all with distinct characteristics and habitats. General habitat associations of Klebsiella species are as follows: K. pneumoniae—humans, animals, sewage, and polluted waters and soils; K. oxytoca—frequent association with most habitats; K. terrigena— unpolluted surface waters and soils, drinking water, and vegetation; K. planticola—sewage, polluted surface waters, soils, and vegetation; and K. ozaenae/K. rhinoscleromatis—infrequently detected (primarily with humans).
