ZOONOSES AND INFECTIOUS DISEASES

Awareness of Zoonotic diseases: Zoonotic diseases affect livestock and causes heavy economic burden. A survey study conducted in Wayanad to ascertain the knowledge, attitude and practice (KAP) of major zoonotic diseases revealed that majority of the farmers practice control measures such as deworming of animals, gives importance for farm biosecurity and were also aware of major zoonotic diseases (*Dr. Lijin James; Major Advisor: Dr. Prejit). In a study carried out in Bidar district of Karnataka concluded that the livestock farmers were well aware of disease like rabies and FMD and their control programmes (*Dr. Ambika; Major Advisor: Dr. Prejit). In a cross sectional study conducted in 100 dairy farmers at Perambalur district of Tamil Nadu State revealed that 74 per cent and 77 per cent dairy farmers were aware about deworming and zoonotic diseases, respectively. 45, 78 and 64 per cent farmers were aware on usage of disinfection, frequency of disinfection usage in hand washing and frequency of livestock shed cleaning respectively. 44 per cent and 48 per cent spending amount Rs.751-1,000 for treating the disease per year /animal/person respectively. 56 per cent respondents are aware of route of transmission of zoonotic diseases. 33, 30 and 19 per cent received the sources of information from Media, Veterinarian and Physician. Garrett ranking was used to analyze the Specific knowledge about the Zoonotic disease and revealed that knowledge on disease and symptoms of zoonotic diseases is 86.34 per cent. Article was published in Int. J. Curr. Microbiol. App. Sci (2017) (Dr. M. Bojiraj; Major Advisor: Dr. Prejit ).

 

Rabies is a fatal infectious disease with high case-fatality rate characterised by an acute progressive and almost fatal encephalomyelitis. The study conducted to explore the effect of animal birth control (ABC) and anti-rabies vaccination (ARV) in controlling canine rabies suggested that both ABC and ARV programmes are highly essential to eliminate the infection and migration of infected animal for sustainable rabies control (*Dr. Supriyaraj D; Advisor: Dr. Prejit).

 

A study done to characterize animal bite re-exposure in human and levels of anti-rabies antibodies in their blood sample, revealed that in 38% cases animal bite re-exposure occured in the streets and young male and students are more vulnerable for animal bite re-exposure. Lower limb is the commonest biting site involved with category III among animal bite re-exposure cases. Playing with animals, teasing and trespassing the animal territory were commonest provocation for animal bite re-exposure (*Dr. Girraj Singh.; Major Advisor: Dr. Prejit.).

 

A study was designed to assess knowledge regarding rabies among lower and upper primary school students in Calicut district of Kerala and to impart health education to them. There was inadequate awareness of rabies among school students which shows the need of awareness classes in school. Positive correlation of attitude and knowledge is an indicative of the fact that attitude of students can increase by increasing the awareness classes (*Dr. Aswathy S.; Major Advisor: Dr. Prejit.).

 

 A knowledge survey conducted to know the awareness of Rabies among the dog-bitten victims of Kannur recorded positive response to the fact that respondants were aware of washing of wound with soap and water as an effective first aid to prevent rabies as well as visiting a physician for post exposure treatment (*Dr. Soya E.; Major Advisor: Dr. Deepa P.M.).

 

On diagnostic front on the usage of immune-chromatographic assay and Fluorescent antibody test to detect rabies viral antigen in decomposing brain samples of dogs proved that using immune-chromatographic assay is effective in detecting Rabies even after 8 days of autolysis. FAT could be a reliable tool when the carcass was submitted afresh or in the earlier stages of putrefaction (Dr. Tessy D.L.; Collaborating Centre: State Institute of Animal Disease Diagnosis, Palode, Trivandrum; Major Advisor: Dr. Arun George). In a study carried out to assess the awareness of rabies among animal owners of Thrissur Corporation found that the awareness levels were not influenced by sex and age and is attributed to literacy rates and increased percolation of media among population (*Dr. Aneesh A.; Major Advisor: Dr. Ajith Jacob George).

 

Leptospirosis is endemic to Kerala with increasing reports during monsoon. Water samples collected from canals, backwaters, rain-harvested areas in and around Alappuzha subjected to dark field microscopy (DFM) and PCR detection revealed the fact that those occupied in the paddy fields were vulnerable to the disease and require awareness on the safety precautions to control the disease (*Dr. K. Vrinda Menon; Collaborating Centre: Department of VPH, COVAS, Mannuthy; Major Advisor: Dr. B. Sunil). In another study to investigate the occurrence of leptospirosis in cattle urine samples by DFM, cultural isolation and PCR revealed the presence of leptospirosis (Data not published). It was suggested that a routine check-up from a qualified Veterinarian with proper vaccination is essential (*Dr. Nair Archana Shivakumar; Collaborating Centre: Department of VPH, COVAS, Mannuthy ; Major Advisor: Dr. B. Sunil ). The survey conducted at Thrissur with regard to the overall awareness of leptospirosis and it was recommended that awareness  programs and training for high-risk groups regarding leptospirosis could prove effective in controlling the disease (*Dr. Sarika N.; Major Advisor: Dr. Binu K Mani). In another study conducted at Pathanamthitta revealed the importance of agricultural practices in the occurrence of disease and concluded the need of awareness among the risk group to prevent the disease (*Dr. Viji V. R.; Major Advisor: Dr. Sujith S ). In a study conducted to detect leptospirosis from dogs and humans using MAT and IgG ELISA identified Leptospira interogans hebdomadis and Leptospira interogans canicola are prevalent in canines. On screening human samples, it was concluded that the veterinarians are at high-risk of contracting infections from infected canines and appropriate precautions need to be taken (*Dr. Amel Dev P.; Collaborating Centre: TVCC, COVAS, Mannuthy; Major Advisor: Dr. P.V. Tresamol).

Tuberculosis is one of the important bacterial zoonotic disease in India. A survey carried out in tribal colonies of Calicut with regard to awareness of the diseases and control through hygiene (personal hygiene, food hygiene, food habits, adverse effect of alcohol consumption and tobacco usage) revealed the need to sensitize people about the disease and start a TB free drive in Kerala (*Dr. Jayasree K.V.; Major Advisor: Dr. Leeba Chacko).

 

Toxoplasmosis is an emerging food-borne parasitic infection responsible for embryonic death, resorption, foetal death and mummification. A study conducted in feline faecal samples revealed a higher occurrence of T. gondii by microscopy and PCR assay which indicates a wide spread distribution of the parasite and that one health approach is required for its effective prevention and control (*Dr. C. Latha; Collaborating Centre: Department of  VPH, COVAS,  Mannuthy; Major Advisor: Dr. P.V. Tresamol). In another study, ELISA-based sero-screening in goats (showing abortion) indicated an alarming rate of incidence of toxoplasmosis (*Dr. Preetham Kumari C.B.; Collaborating Centre: Department of Veterinary Pharmacology and Toxicology, COVAS,  Mannuthy ; Major Advisor: Dr. Sujith S).

 

Campylobacteriosis is one of the leading causes of bacterial food-borne illness worldwide. A study was undertaken to determine the occurrence of thermophilic Campylobacters in dogs and cats employing conventional as well as molecular methods. It was concluded that the dogs can serve as a potential source of Campylobacter infection to humans through food, water, environment and in turn from humans/animals by direct contact (*Dr. Savita Rudrappa Kashappanavar; Collaborating Centre: Dept. of VPH, Mannuthy; Major Advisor: Dr. Binsy Mathew). The study undertaken in cats emphasized the importance of good rearing and hygienic practices along with the need for awareness about its zoonotic implications. Besides, it was found that the Campylobacteriosis is greatly influenced by age, health status and type of diet (*Dr. Vani R Pillai; Collaborating Centre: Dept. of VPH, Mannuthy; Major Advisor: Dr. Binsy Mathew). In yet another study to detect thermophilic Campylobacters from meat samples of pig and poultry in Bareilly using molecular methods, C. coli revealed the highest occurrence rate (*Dr. Tayade Ravindra Shivaji; Collaborating Centre: Department of VPH, ICAR-IVRI, Bareilly ; Major Advisor: Dr. Prejit).

 

Other Zoonotic Diseases: The sero-screening was carried out for the detection of anthrax, brucellosis, leptospirosis and bovine tuberculosis using ELISA, RPBT, MAT and bovine TB iELISA  (*Dr. Arun Kurian; Collaborating Centre: Department of  Veterinary Microbiology, COVAS,  Pookode ; Major Advisor: Dr. Siju Joseph). The sero-screening conducted at Thiruvananthapuram among community-owned dogs detected Leptospira and Leishmania spp. and necessitated the need for conducting awareness on zoonosis and personal hygiene (*Dr. Nandakumar S.; Collaborating Centre: Chief  Disease Investigation Office, Palode, Trivandrum ; Major Advisor: Dr. Koshy John). The sero-screening of Brucellosis in goats at Calicut using RBPT and i-ELISA assays concluded that the occurrence of infection increases with age; dairy products were found to be the major source of infection for people who do not have direct contact with animals (*Dr. Bijlee Bhaskar; Major Advisor: Dr. Arun George ). A study carried out to detect Coxiella burnetti from bovine samples revealed positivity by PCR and ELISA. Further, awareness programmes were conducted for the human handlers (*Dr. Pankaj Dhaka; Collaborating Centre: Guru Angad Dev Veterinary and Animal Sciences University, Ludhiana; Major Advisor: Dr. C. Latha). A study was designed to develop an application to aid in the diagnoses of the  zoonotic diseases along with providing information on their management in humans and animals. This expert system can be also used to create awareness in common people about the zoonotic diseases with their peculiar symptoms. This is developed using Python  2.7  and  the  Flask  web  framework.  (*Dr. Netra Ansar.; Major Advisor: Dr. Prejit.).

 

ANTI-MICROBIAL RESISTANCE

 

Food-borne pathogens pose a major emerging threat worldwide. The study conducted to know the occurrence and antibiotic susceptibility testing of the emerging food-borne pathogen, Arcobacter spp. by cultural and molecular methods from retail chicken meat samples in and around Bengaluru, revealed that the recovered Arcobacter isolates were sensitive to ampicillin, gentamicin and kanamycin and resistant to cephalothin, vancomycin and clindamycin. It was also imperative from the study that due to the presence of antimicrobial resistant strains in retail chicken, mass education programme for the butchers needs to be conducted on hygienic handling and processing of poultry and poultry meat products (*Dr. Nishanth C.; Collaborating Centre: Department of VPH, Banglore ; Major Advisor: Dr. Prejit).

 

Mastitis, though being an important production disease in dairy cattle, continues to have a major economic impact on dairy industry. Indiscriminate use of antimicrobial agents results in treatment failure as well as emergence of antimicrobial resistance. A farm-based study conducted in Wayanad district recovered Staphylococcus aureus, Streptococci and Micrococci from milk; amoxicillin was the most sensitive antibiotic and ampicillin was the most resistant antibiotic (*Dr. Mukesha Kini M.A.; Collaborating Centre: Dept. Of Preventive Medicine, Pookode ; Major Advisor: Dr. Smitha J.P.). In another study, tetracyclines (tetracycines, oxytetracycline, doxycycline) and fluoroquinolones (enrofloxacin, norfloxacin, ciprofloxacin, ofloxacin) was found to be sensitive antibiotics.

 

In a survey conducted on Antimicrobial usage and antimicrobial resistance among the public of Bengaluru revealed that majority of the people were not aware about the antibiotic resistance. The observations made clearly shows that majority of study population was not aware about resistance caused by antibiotics. The survey concluded that the people of middle age group should be made aware of the usage of antibiotics, especially the livestock workers, as they are more prone to AMR (*Dr. Aishwarya N.; Major Advisor: Dr. Prejit).

 

In a study conducted to determine the ability of methicillin resistant S. aureus (MRSA) from canines using conventional and molecular methods revealed the potential risk involved in the transmission of MRSA between dog handlers and human handlers (*Dr. Hamna Hakkim; Collaborating Centre: COHEART, Pookode; Major Advisor: Dr. Prejit).
