Aims: Leptospirosis is endemically prevalent in coastal area of south Gujarat. Generally, pets are vaccinated against Leptospira interrogans but whosoever left unvaccinated, are prone to infection. The present study was conducted to detect canine leptospirosis and its prevalence from south Gujarat. Place and Duration of Study: A total of 46 serum samples and 33 urine samples were collected from 56 dogs suspected of having leptospira infection. The study was done from September 2019 to May 2020. Methodology: Serum samples were diagnosed by IgG based ImmunoComb solid phase dot ELISA test for antibody against genus specific Leptospira interrogans. Urine samples were visualized under dark field microscopy (DFM) following laboratory manual on leptospirosis of WHO. Sex and age of dogs were noted to find out the percent positivity and prevalence. Chi square test was applied to find out any significant difference among the age groups. Results: Out of 46 serum samples, 17 (36.95%) found positive by dot ELISA and out of 33 urine sample, 13 (39.39%) found positive by DFM. Sex wise prevalence found 42.10 percent (16/38) in Male while 55.55 percent (10/18) in female dogs. Age group wise prevalence was recorded 63.63 percent (07/11) in 1- ≤ 3 years group. 27.77 per cent (05/18) in > 3- ≤ 6 years group whereas, 51.85 percent (14/27) in > 6- ≤ 12 years group. Conclusion: Detection and prevalence of canine leptospirosis were studied first time from Gujarat. Overall 46.42 percent (26/56) dogs were diagnosed positive for canine leptospirosis. Dogs having age group of 1- ≤ 3 years found more susceptible. Prevalence was found more in female than male dogs.

Prevalence of anti-leptospiral antibodies and frequency distribution of Leptospira serovars in small ruminants in enzootic South Peninsular India

et al. 2021

View full text Add to dashboard Cite

Background and Aim: For understanding the epidemiology of leptospirosis, the confined abundance of several species of pathogenic leptospires and knowledge on the serovar(s) prevalent in the reservoir and carrier hosts may be a useful indicator of transmission to incidental/accidental hosts in a geographical niche. The present study was carried out to ascertain the frequency distribution of Leptospira serovars and the prevalence of anti-leptospiral antibodies in small ruminants (sheep and goats) in the epidemiological units (villages) in the coastal districts of enzootic regions in South Peninsular India. Materials and Methods: A total of 1167 serum samples (sheep n=299 and goats n=868) from apparently healthy animals, randomly collected from various epidemiological units were tested in microscopic agglutination test (MAT) using 18 reference Leptospira serovars antigens. Results: The overall seroprevalence of 40% (at 95% confidence intervals [CI]: 36.82-42.43) in small ruminants (44% [95% CI: 40.49-52.26] in sheep and 38% [95% CI: 34.96-41.41] in goats) was observed with the predominance of Icterohaemorrhagiae, Javanica, Australis, Hurstbridge, and Pyrogenes serogroup anti-leptospiral antibodies in the studied region. The Chi-squared test revealed that the presence of anti-leptospiral antibodies is significantly not independent (associated) across the administrative division (Chi-square=105.80, p<0.05) as well as for sheep (Chi-square=34.67, p<0.01) and goats (Chi-square=68.78, p<0.01). Among seropositive samples (n=462 reactors), the MAT was positive for more than one serovar in 73% of sheep (95/131) and 53% of goats (177/331), representing an overall 59% cross-reactive prevalence in small ruminants. The determined frequency distribution (varied among small ruminants) of the employed serovars representing major reactive serogroup was Icterohaemorrhagiae (29.87), Javanica (20.78), Australis (20.35), Hurstbridge (16.23), Pyrogenes (15.8), Djasmin (15.58), Bataviae (15.37), Autumnalis (14.5), Canicola (14.5), Hebdomadis (14.07), Shermani (13.64), Panama (13.42), Sejroe (12.77), etc. Conclusion: This study indicates alarmingly high seroprevalence of leptospirosis in small ruminants with existing endemicity in the studied region in South Peninsular India. Further, these prevalent serovars in the administrative division may be of use in the reference panels of antigens in the MAT in both humans and animal disease diagnostic laboratories for effective and timely diagnosis of leptospirosis and to combat the challenges in public health.
