Fisheries play an important role in increasing the Nepalese economy as well as sustaining livelihood of some ethnic groups of our country. With the increased demand of fish, pisciculture have also increased to a great extend. Due to the rise in fish culture, there has been also rise in fish diseases. The study aims to investigate different parasitic, bacterial, fungal diseases in fish and to suggest treatment to control the diseases in four different fish farm of Nepal. A cross- sectional qualitative method was used to collect data from four selected fish farm (Kakani, Trishuli, Begnas, Mirmi) of Nepal. Infected fishes were transferred to the lab in oxygen filled plastic bags and further tested for bacterial, fungal and parasitic infection. The result of the study indicates that Epizootic Ulcerative Syndrome was the most common bacterial-fungal disease that had a significant impact on common carp fish especially in Trishuli, Begnas and Mirmi. Coccidiosis caused by Eimeria spp was found to be a growing problem in rainbow trout farming (Kakani, Nuwakot) infecting intestine, liver, gut and skin causing yellow diarrhea and skin lesions. Trichodina was observed number one problematic parasitic in carp culture not only in government farm like Begnas and Mirmi, but also in commercial farms in most of the fishery areas of the country. Fin rot were more commonly reported during winter months affecting common carp, Silver carp, Bighead carp, Fingerling Fish causing fin erosion in them. Ascites in brood fishes (Trishuli) was noticed which may be due to bacterial infection and due to nutritional deficiency. Besides this, white spot in the gills (a protozoan parasitic disease) was perceived and to control it Neodox with Formalin (150ppm) was used and was found to be very effective. This study also identified some fish health management related problems in fish farms of Nepal such as lack of assistance, poor technical knowledge, and lack of suitable diagnostic laboratory and their proper use.

An experiment was conducted for 190 days from September 15, 2005 to March 25, 2006 in 12 outdoor concrete tanks of 24 m2 (4.9 m × 4.9 m) size and 1.25 m in water depth, at the Institute of Agriculture and Animal Science (IAAS), Rampur, Chitwan, Nepal to evaluate the growth performance and profitability of silver barb in mono and polyculture systems. The experiment was laid out in a completely randomized design (CRD) with four treatments having three replications each. There was one mono and three polyculture systems of silver barb with different fish species as treatments: (1) Silver barb at 1.5 fish/m2 (control); (2) Silver barb at 1.5 fish/m2 plus common carp at 0.2 fish/m2; (3) Silver barb at 1.5 fish/m2 plus male Nile tilapia at 0.3 fish/m2; and (4) Silver barb at 1.5 fish/m2 plus carps at 0.5 fish/m2 (silver carp 40%, bighead carp 20%, and common carp 40%). Silver barb were fed with 23% CP feed @ 4% body weight daily.At harvest, the mean weight, daily weight gain, gross fish yield (GFY) and net fish yield (NFY) of silver barb in monoculture treatment were significantly greater than in polyculture with common carp (p < 0.05), whereas there were no differences with polyculture with Nile tilapia (p > 0.05). However, survival of silver barb was not significantly different among treatments (p > 0.05). The combined GFY in polyculture with Nile tilapia treatment was significantly greater than in polyculture with common carp and in polyculture with other carps (p < 0.05). The NFY was highest in polyculture with Nile tilapia (4.4 ton/ha/yr), intermediate in polyculture with other carps (3.5 ton/ha/yr) and lowest in polyculture with common carp (2.9 ton/ha/yr) and monoculture (2.5 ton/ha/yr). Water quality parameters were not much difference in different treatments; however, water temperature was a crucial as it was less than 20°C for about 3 months (mid November to mid February). All the treatments produced positive net returns; however, the net returns were higher in polyculture with Nile tilapia than in other treatments. This study demonstrated that silver barb polyculture with male Nile tilapia is far better than other combinations.Keywords: Silver barb, Monoculture, Polyculturedoi: 10.3126/on.v6i1.1653Our Nature (2008)6:38-46

The chemical and fatty acid composition were evaluated of commercially important fish species (common carp, silver carp, bighead carp, grass carp, Wels catfish, and zander) which were collected from retail stores in the area of Novi Sad, Republic of Serbia. The amount of protein was the highest in zander (19.27%) and the lowest in grass carp fillets (14.73%). The percentage of fat ranged from 1.8 in zander to 10.07 in common carp. The total cholesterol content was the highest in Chinese carps fillets (approximately 65.38 mg/100 g), and the lowest in Wels catfish (33.14 mg/100 g). SFA were lowest in zander (28.6%). Bighead carp meat contained the highest percentage of PUFA (33.73%) while the lowest percentage was detected in common carp (20.1%). The chemical and fatty acid compositions of fish vary greatly between different species and within the same species. The quality of fish meat in Serbian retail stores is quite good but it should be improved by using feed mixtures on fish ponds.

Background: Penicillin resistance among Staphylococcus aureus commonly encountered in the hospital admitted patients. Detection of antibiotic sensitivity in hospital acquired methicillin resistant Staphylococcus aureus infections is important as it has great influence on empiric antibiotic prescription, successful control of infection, prevention of spread of disease and successful patient management. This study aimed to detect the frequency of HA-MRSA from pus samples in a hospital setup with assessment of their antibiotic susceptibility patterns. Method: A cross-sectional study was conducted in the Microbiology department of Basic Medical Science Institute, JPMC, Karachi from January 2015 until December 2015. Pus samples from surgical site wounds, skin lesions, abscesses from surgical and medical wards and ICUs were collected. According to the standards given by CLSI 2014, MRSA testing of the samples was done and susceptibility testing for antibiotics was performed. Inducible clindamycin resistance was detected by D-Test; E Test. determined MIC (minimum inhibitory concentration) for vancomycin. The data was analyzed by SPSS version 16. Result: Out of the 149 MRSA identified from the pus samples, 106 (71.14%) samples were HA-MRSA. The number of male patients was more than the female patients (67.66%). Out of the 106 HA-MRSA, 91(85.8%) were sensitive to TMP/SMX, 98(92.5%) to rifampicin, 12(11.6%) to gentamicin, 85(80.2%) to tetracycline, 11(10.4%) to erythromycin, 37(34.9%) to clindamycin, 20(18.9%) to ciprofloxacin, 106 (100%) to both vancomycin and linezolid. Conclusion: HA-MRSA showed sensitivity to TMP/SMX and vancomycin making them effective drugs to use in combination in superficial infections. The drug linezolid also showed 100% sensitivity.

This study concentrated on the assessment of the prevailing parasitic fish diseases in some marine fishes at Ismailia province and how to control the infestation using microalgae. This study was carried out on 1080 pre-mature fish (360 D. labrax (225±25 g) and 360 S aurata (150±25 g) and 360 M. cephalus (125±25 g) collected from similar ponds of studies to be examined at the end of treatment. In addition to that we followed non-treated fish (1080 premature). The infested fish showed dark colour and respiratory signs. Post mortem lesions were a presence of congestion or paleness and destruction of gill filaments. The total prevalence of infestation was the total prevalence of parasitic infection of non-treated fishes was 45.83 %. The highest percentage was in D. labrax 56.94 % followed by S. aurata 47.22%, the lowest percentage in M. cephalus 33.33. The total prevalence of parasitic infection in premature treated with 2 g algae was 28.79%, followed by 3 g algae was 23.60 %, while the lowest percentage with 5 g algae was 20.37 % respectively. The detected species of parasites were protozoal parasites, Amyloodinium ocellatum and Riboscyphidia in additions of marine monogenea, Lamellodiscus diplodicus isolated from D Labrex, Mugil Cephalus and S aurata. The present study concluded that, the use of microalgae instead of fish meal decreased parasitic infestation in marine fish. The histopathological alteration of natural infested examined fishes was also recorded.

Background: Intestinal parasitic infections are the one of the most common health problems in developing countries. Objective: A number of patients die annually due to complications caused by these parasites.Therefore, the aim of this study was to investigate the rate and type of parasitic infections, determine the factors affecting them in Ilam city and also provide strategies to prevent them.In this descriptive cross-sectional study conducted in one of the Ilam labs in 2016, 417 stool specimens were randomly collected. All specimens were examined using direct and ethanol formaldehyde.Suspect specimens were examined using Trichrom staining. Demographic information was also recorded in a questionnaire, and finally the results were analyzed using statistical software SPSS 20.The data were then compared with Chi-square test. Results: Out of the 417 patients examined, 59 (14.1%) were infected with intestinal parasites. The type of parasitic infection in 9.4% was Blastocystis hominis, 3.6% Entamoeba coli, 0.5% Entamoeba histolytica, 0.5% Giardia and 0.2% Trichomonas hominis. Conclusion: Despite the improvement of public health, parasitic infections are still considered as one of the health problems in the city of Ilam. Therefore, proper planning, public health education, raising the level of health in the area and the provision of safe drinking water are some of the ways to reduce parasitic infections in the region.

Background: The aim of the present study is to describe the occurrence of Blastocystis sp. detection among asymptomatic subjects and patients with irritable bowel syndrome in order to evaluate the potential association between irritable bowel syndrome and the parasitic infection. Methods: Cross-sectional study where adult patients with irritable bowel syndrome diagnosed according to Rome IV criteria were included. A control group was formed by asymptomatic subjects older than 18 years. Exclusion criteria were: immunosuppressive condition or having received any drug with demonstrated activity against Blastocystis sp. within the last 6 months before study inclusion. Epidemiological and clinical information was collected from all included participants. Two stool samples were obtained from all participants: one sample for microscopic examination and one sample for Blastocystis sp. PCR detection. Blastocystis sp. infection was defined by the positivity of any of the diagnostic techniques. Results: Seventy-two participants were included (36 asymptomatic subjects and 36 patients with irritable bowel syndrome). Thirty-five (48.6%) were men, and median age of participants was 34 (IQR 29–49) years. The overall rate of Blastocystis sp. carriage was 27.8% (20/72). The prevalence assessed through microscopic examination was 22.2% (16/72), while the prevalence measured by PCR was 15.3% (11/72). When comparing the presence of Blastocystis sp. between asymptomatic subjects and IBS patients, we did not find any statistically significant difference (36.1% vs. 19.4% respectively, p = 0.114). Conclusions: regarding the occurrence of Blastocystis sp., no differences were found between asymptomatic participants and patients with irritable bowel disease irrespective of the diagnostic technique performed.

Background. Neglected tropical diseases continue to be one of the leading causes of morbidity and mortality in the developing world. Psychiatric patients are among groups at risk for parasitic infection although control and monitoring programs largely overlook this population. This study aimed at determining prevalence and factors associated with intestinal parasitic infection among patients admitted to a psychiatric facility.Method. The study followed cross-sectional design; all the residing patients that met the inclusion criteria were included in the survey. Stool samples were collected and examined by direct wet preparation and formol-ether concentration. Data were analyzed with STATA version 12.1; Chi-square test was computed to determine the level of significance atpvalue < 0.05.Results.Of all 233 patients who returned the stool samples, 29 (12.45%) screened were positive for an intestinal parasite. There was no significant association between parasite carriage and age, sex, or duration of hospital stay.Conclusion. The study shows that intestinal parasitic infection is common among patients in a psychiatric facility and highlights that parasitic infections that enter through skin penetration may be a more common mode of transmission than the oral route. Furthermore, the study underscores the need for surveillance and intervention programs to control and manage these infections.
