2024
C. Sheeba Anitha Nesakumari | N. Thirunavukkarasu
Diet of mud crab S.tranquebarica consists of crustaceans, mollusks, fish remains, detritus, debris and undigested flesh. Quantitative analysis of the gut contents contributed 53.18% crustaceans, 24.69% molluscan remains, 16.91% fish remains and 3.02% & 1.23% of detritus and debris respectively. The study indicated that this species is primarily predators of sessile and slow moving benthic macro invertebrates. The presence of detritus, debris and undigested flesh items in the stomachs suggested that the crabs are detritivorous consuming fresh and decaying flesh of all kinds. The sex wise and size wise of diet in these crabs may be largely due to relative abundance of prey species in the habitat or related to change in cheliped strength and foraging behaviour.

T.R. Pugazhenthi | A. Elango | B. Dhanalakshmi
Swiss cheese samples collected aseptically from private dairies were analysed for the presence of Penicillium citrinum and for the efficacy of antimycotic agents against P.enicillium citrinum. The spore suspension of Penicillium citrinumand antimycotic agents like pimaricin and potassium sorbate at specified concentrations were added to cheese and stored at 250 C for 21 days. The keeping quality of cheese was assessed at 0, 7, 14 and 21 days. On statistical analysis, pimaricin at 10 ppm concentration was found to be highly significant (P <0.01) over 5 ppm of pimaricin, 500 and 1000 ppm of potassium sorbate with regard to anti-mycotic effect.

The study of the influence of aqueous and hydro alcoholic extracts of Tinospora cordifolia on human mammary tumor cell line MCF-7 is a common way of discovering potential therapeutics for treating people suffering from hormone-dependent problems and diseases. In the present study, the cells were treated with the extracts at three different doses viz., 200 μg/ml, 400 μg/ ml and 600 μg/ml. Both the extracts produced degenerative changes in the cell in dose-dependent manner with maximum effect being noticed at the dose level of 600 μg/ml. Thus, these findings suggest that the extracts from Tinospora cordifolia have potential for acting as an antiproliferative agent in mammary tumour.

P. Jalantha | C. Balachandran | N. Pazhanivel
The present study was carried out to evaluate the effect of curcumin on lipid peroxidation and antioxidant levels in DMBA (7, 12 Diemthyl Benanthracene) induced mammary carcinogenesis in rats. Twenty four Sprague-Dawley rats were equally distributed to control, DMBA, Tamoxifen (Standard drug) and curcumin groups. DMBA group showed significant (P<0.05) increase in lipid peroxidation and antioxidants superoxide dismutase (SOD) and catalase (CAT) levels besides reduced glutathione (GSH). Whereas, curcumin and Tamoxifen treated groups did not show any significant difference in lipid peroxidation and antioxidant status when compared to the control. Selective growth advantage of tumour cells was evident in the DMBA group and curcumin was able to prevent lipid peroxidation.

K. Rama Rao | Makkena Sreenu | K.B.P. Raghavender | P .V. S. Kishore
A study was conducted in buffaloes suffering with horn affections .The physiological and haematological parameters were within the normal limits in all the horn affections, but the plasma cortisol and C-reactive protein were more than the normal levels in all the horn affections for initial periods. A radiological sign like increased radio-opacity was noticed in the septic horn cases. Microscopic examination of biopsy samples of horn and skin following amputation revealed normal histology except in horn cancer where squamous cell nests and mitotic figures in the squamous cells were observed.

Campylobacter is the commonest reported bacterial cause of infectious intestinal disease. To study the epidemiology of Campylobacter infection among children, 100 stool samples along with patients anamnesis were collected from the clinical diarrheic reported to Enterology unit of Institute for child Health and centre for Children, Egmore, Chennai, Tamil Nadu between May 2013 to June 2013. Samples were subjected to traditional culture and modern PCR techniques, both of which revealed same results of 13% prevalence of Campylobacter sps (8% C.jejuni & 5% C.coli). Analyzing the patients anamnesis to study the epidemiological determinants, sex has a significance (P<0.05). Age and residential area have no significance and summer season and cross contamination could be probable determinants for the infection.

Data relating to 130 sows, 19 boars from 400 farrrowings spread over a period from 1984 to 1992 were utilized to study genetic and non-genetic effects in variation of litter size and weight at birth and at weaning. The overall mean litter size at birth (LSB)was 6.83 ± 0.13 piglets. The effects of period, season of farrowings and inbreeding on litter size at birth were not significant (P>0.05).The overall least squares mean of litter size at weaning(LWW) was 4.83 ± 0.12 and was significantly (Pd”0.05) affected by in breeding. Litter weight at birth (LWB) had a least square mean of 7.81 ± .16 kg and it was significantly (Pd”0.05) affected by period of farrowing. The mean LWB of non-inbred sows was 8.22 ± 0.19kg and that of inbred sows was7.41 ± 0.29 kg. The overall least squares mean for litter weight at weaning (LWW) was 39.36 ± 1.25 kg and inbreeding of sow exerted significant effect on LWW. The LWB and LWW were significantly affected by period of farrowing. The litter size at birth and at weaning and litter weight at birth and at weaning was not significantly affected by season of birth. The heritability estimates of litter size at birth and litter size at weaning were 0.096 ± 0.09 and 0.816 ± 0.27 respectively. The corresponding heritability values for LWB and LWW were 0.41 ± 0.18 and 0.53 ± 0.21 respectively.

2024
S.C. Kumar | C. Renukaprasad | Placid. E. D’Souza | B.S. Pradeep
Faecal samples of 264 sheep from 4 different sheep farms belonging to three different districts of Karnataka were screened to note the incidence of gastrointestinal nematodes. It was found that 93% of the sheep harboured strongyle infection. The faecal egg counts were found to be light to moderate. The in vitro egg hatch assay was employed to assess the resistance of strongyles in 4 sheep farms. The ED50 value for albendazole ranged between 2.5μg/ml to 6.9 μg/ ml which indicated the resistance of the gastrointestinal nematodes. All the samples were also subjected to another in vitro test, viz., larval development assay. The values ranged between 3-2μg to 4.2μg / ml which also indicated the development of resistance to albendazole. Larval paralysis assay confirmed the development of resistance to albendazole.

K. Radha | Lakshmi S. Nath
Microbial quality of air in a dairy processing plant was evaluated to ascertain the contribution of air as a source of contamination and spoilage of milk and milk products. The mean total aerobic counts obtained in the air by sedimentation method were 32.66 ± 3.82, 25.32 ± 4.17 and 33.36 ± 3.53 cfu/m 2 in raw milk reception dock, pasteurization room and product preparation room respectively. The respective mean total coliform counts were 1.52 ± 0.14, 0.66 ± 0.08 and 0.99 ± 0.16 cfu/ m2. Total coliform count observed in the raw milk reception dock was significantly higher (P< 0.01) than the other areas. The mean Staphylococcal counts were 2.52 ± 0.10, 3.84 ± 0.31and 5.82 ± 0.30 cfu/ m2. The product preparation room showed highest mean Staphylococcal counts followed by pasteurization room and raw milk reception dock. The mean yeast and mould counts obtained were 5.42 ± 0.39, 3.84 ± 0.31and 5.82 ± 0.30 cfu/ m2 in raw milk reception dock, pasteurization room and product preparation room respectively. Effect of fumigation on the microbial quality of air in the dairy processing area was also studied by comparing the microbial load in the air before and after fumigation. Fumigation practice followed in the dairy processing area was highly effective against total aerobic organisms, coliforms, and Staphylococci but not very effective in the case of yeast and moulds.
