“…Variation in rainfall, humidity, and climate, coastal regions are linked to a high prevalence of bovine leptospirosis in Andhra Pradesh. The study results, were in agreement with the findings of Alamuri et al (2019), who observed 68.08% of seropositivity in Andhra Pradesh, whereas Prameela et al (2013) observed 44.7% of seropositivity with Pomona, Autamnalis, and Hardjo as predominant serovars. However, Balamurugan et al (2016a) reported the seroprevalence ranging from 45 to 75% in other enzootic states of India.…”

“…However, Balamurugan et al (2016a) reported the seroprevalence ranging from 45 to 75% in other enzootic states of India. In this pilot study, the seroprevalence in the farms' animals of Telangana state was 17.8 % which is concordant with the earlier studies where the seroprevalence was 16.3% (Prameela et al, 2013). The seropositivity of bovine leptospirosis reported in the states/UTs adjoining to the Telangana and Andhra Pradesh was 37% in Odisha (Balamurugan et al, 2017), 41% in Maharashtra (Balamurugan et al, 2016b), 87% in South India (Natarajaseenivasan et al, 2011), 44% in Tamil Nadu and Karnataka (Saranya et al, 2021;Balamurugan et al, 2018).…”

“…The predominantly reacted pathogenic serovars representing serogroup-specific antibodies prevalent in the present study were Icterohemorrhagiae, Hebdomadis, Bangkinang, Australis, Djasmin, Hurstbridge, Panama, etc. The prevalence pattern of predominant serovars was similar to the earlier studies reported by Alamuri et al (2019) and Prameela et al (2013), except for Djasmin and Hurstbridge serovars which were observed along with other pathogenic serovars. Even though Hardjo is considered common in cattle, other serovars were also noticeable in many parts of India and the world (Balamurugan et al, 2016a;Patel et al, 2017).…”

“…In the current study, the health status of the animal was also identified as one of the significant risk factors associated with leptospirosis, which is concurrent with that of Prameela et al (2013), who reported that the history of abortion at the animal level is associated with the occurrence of bovine leptospirosis. It is also in agreement with the findings of Fávero et al (2017), where the cows which were seropositive to Leptospira spp.…”

“…The study was carried out in two southern states of India endemic to bovine leptospirosis, namely Andhra Pradesh and Telangana (Alamuri et al, 2019;Prameela et al, 2013). The bovine population in these states includes crossbred (crossed with Holstein Friesian and Jersey cattle), indigenous breeds (Sahiwal and Gir cattle and Murrah buffaloes), and non-descriptive breeds of animals.…”

L eptospirosis, a spirochaetal zoonosis, has emerged as a serious global veterinary and public health problem affecting the health of both animals and humans in tropical and subtropical countries (Costa et al., 2015). Leptospirosis is caused by pathogenic species of the genus Leptospira and results in high morbidity and mortality (Ellis, 2015). The disease is prevalent in humans and a variety of mammalian hosts such as rodents, bovine, sheep, goats, dogs, Short communicationAbstract | Leptospirosis is one of the most economically important diseases of the cattle and buffaloes population worldwide and is caused by serovars of pathogenic Leptospira. A pilot study was conducted in some of the dairy farms located in Telangana and Andhra Pradesh, endemic states of India, during 2017 to investigate the seropositivity of bovine leptospirosis in dairy animals and associated risk factors at the farm level. The semi-structured questionnaire was designed as per the literature and used to collect leptospirosis associated risk factors along with serum samples from eight non-vaccinated dairy herds. The collected serum samples (n=56) were examined for detection of leptospiral antibodies using the Microscopic Agglutination Test (MAT), the gold standard serological test. The Chi-square and odds ratio analyses were employed to identify the important risk factors for leptospirosis in dairy farms. The study revealed that the seroprevalence of bovine leptospirosis at an individual animal and farm level was 39.8% and 75%, respectively, associated with age (p=0.041) and the health status of the animal (p=0.0001) as the significant risk factors. The predominantly observed reacted serovars were Icterohemorrhagiae (31.8%), Hebdomadis (27.3%), Bangkinang (22.7%), Australis (18.2%), Djasiman, Hurstbridge, Panama, and Pyrogenes (13.6%). Further, studies are required to identify the appropriate farm level/animals level risk factors associated with bovine leptospirosis using large-scale sampling with a refined survey instrument tool.
