The Nilgiri hills and adjoining downhill areas provide favourable ecological conditions for the propagation of haematophagous arthropods owing to richness in vegetation and animal activities. A study has been undertaken during 2008–2010 on the distribution and abundance of ticks of domestic animals in seven different biotopes. A total of 3,008 domestic animals were examined in areas ranging from an altitude of 300 to 2200 meters above mean sea level (MSL) of which 1,335 (44.5%) animals were having tick infestation. A total of 6,012 adult and immature ticks belonging to 12 species (11 ixodid and one argasid) were collected. Eleven tick species were collected from Kallar area situated downhill eastern slopes of the Nilgiris followed by Burliar area (7 species) located at higher altitudes. From Masinagudi area near to dense forests and scrub jungles, five species were recorded. However, at higher elevations on the hills, Udhagamandalam area, only one species was recorded. Among various tick species recorded in the study,Boophilus micropluswas distributed in almost all areas surveyed followed byHaemaphysalis spinigeraandRhipicephalus sanguineus. The factors governing their distribution and epidemiological significance in the transmission of various tick-borne diseases of public health importance are discussed.

Brucellosis is a contagious bacterial disease with worldwide importance and affects a number of animal species and human beings. Although brucellosis in domestic animals has controlled in most developed countries it remains an important public health problem in several parts of the world. But in developing countries brucellosis has both animal and public health importance (Walker, 1999; Radostitset al.,2000; Acha, and Szyfers, 2001; Tsolia et al.,2002).

The species composition and host preference of medically important fleas monitored in urban, semi-urban, and rural revealed 412(65%) and 222(35%) fleas. From urban and rural habitats 90 and 345 fleas were collected respectively. There was a significant difference between urban and rural habitats in flea abundance. From rodents and domestic animals 209 (33%) Xenopsylla cheopis, 203 (32%) X. astia and 222 (35%) Ctenocephalides felis fleas were recorded. Fleas were predominantly found on Rattus rattus 45(83.3%) and Canis familiaris 31(83.8%). Among the habitats, there was no significant difference in rodent flea positivity and dog/cat flea positivity.

The present study was the first attempt to investigate the public health importance of infestation of Ostracoda in some marine food fishes in southeast region of Tamil Nadu India during June 2019 to May 2020 by the method of Becker’s measuring utility by a single-response sequential method. Total 540 fishermen belonging to 5 villages from Ramand District were interviewed to understand the public health issues related the infestation of Ostracoda V. tsujii in ten major marine food fishes i.e. Parupeneus indicus, Lutjanus fulviflamma, Priacanthus hamrur (Snapper), Carangoides gymnostethus, Carangoides malabaricus, Carangoides ferdau (Carangids), Cephalopholis sonnerati, Epinephelus coioides (grouper), Lethrinus ornatus and Plectorhinchus gibbosus (sea bream). Fishermen, local whole sale buyers, small fish-stall owners and fish consumers were part of respondents. It was observed that there was no difference at statistically significant level (P < 0.05) between infested and healthy fish samples in terms of nutritional profile like protein, fat, ash, carbohydrates and mineral nutrients level. Based on the feedback and information obtained from respondents in the present study found that no incidence of health issues or risk associated with food fishes infested with Ostracoda Vargula tsujii (local name – Arattlai) or any other true parasites.

Gambling is a popular pastime in India, as in most cultures across the world. Although research from India is limited, there is enough evidence to suggest that it should be of public health importance. In this brief paper, we look at the evolution of gambling in India and also discuss potential ways forward to address this issue.

Abstract Interpreting the results of epidemiologic studies calls for objectivity and rigorous scrutiny, acknowledging the limitations that temper the applicability of the findings to public health action. Current trends have posed new challenges to balancing goal of scientific objectivity and validity with public health applications. The ongoing tension between epidemiology’s aspirations and capability has several sources: the need to overpromise in research proposals, compromising methodologic rigor because of public health importance, defending findings in the face of hostile critics, and appealing to core constituencies who have specific expectations from the research.

Abstract Background Continuous and non-judicial application of synthetic insecticides to control the tea thrips, Scirtothrips bispinosus (Bagnall), one of the major tea pests in South India has led to certain undesirable issues in the ecosystem besides the presence of the pesticide residues in manufactured tea. Biological control agents are of immense importance in tea cultivation. The present study was designed to isolate Lecanicillium lecanii (Zimmermann) Zare & Gama from the field-collected cadavers of the insects/mites infected by fungi of tea growing areas of Anamallais (Tamil Nadu, South India), and to evaluate their field bio-efficacy against the tea thrips. Results Lecanicillium lecanii isolated from the tea ecosystem had been formulated into a wettable powder (WP) formulation and evaluated against tea thrips under both laboratory and field conditions. Among the several media evaluated, the PDAY (Potato Dextrose Agar + 1% Yeast powder) was found to be the best suitable medium for the growth and germination of spores. Optimum conditions for the growth of L. lecanii were found in PDAY medium at the pH 6-7, temperature 25-30°C and 90-95% RH. Exposure to UV light for more than 30 min significantly inhibited the growth of the fungus. Lecanicillium lecanii at (1 × 107 spore/ha) was found significantly effective against thrips. Fungal development index (FDI) of L. lecanii + jaggery significantly differed than other treatments. Lecanicillium lecanii at 1500g (1×107 conidia/ml) mixed in 400 l of water was effective against the tea thrips. Addition of equal amount of jaggery with L. lecanii wettable powder in the tank mixture could increase the efficacy of the mycopesticide against tea thrips. Conclusion The powder formulation of L. lecanii was found safer to natural enemies present in the tea ecosystem. After fulfilling the requirements for its registration and label claim on tea, this strain of L. lecanii could be commercialized for the benefit of the tea industry for the management of tea thrips in an eco-friendly manner.
