Molecular Characterization of Leptospira Species among Patients with Acute Undifferentiated Febrile Illness from the Municipality of Villeta, Colombia. Trop Med Infect Dis 2024; 9:168. [PMID: 39195606 PMCID: PMC11360529 DOI: 10.3390/tropicalmed9080168] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2024] [Revised: 07/22/2024] [Accepted: 07/23/2024] [Indexed: 08/29/2024] Open
Abstract
Leptospira is a bacterial genus that includes several pathogenic species related to leptospirosis. In Colombia, leptospirosis is a mandatorily reported disease, widely distributed across the country. In the Villeta municipality, leptospirosis has been identified as an important cause of febrile illness; however, to date, no studies have been performed to identify the circulating species. A genus-specific qualitative qPCR was performed on DNA extracted from febrile patients' acute-phase whole-blood samples targeting a fragment of the rrs gene. Positive qPCR samples were further amplified for the adk, icdA, LipL32, LipL41, rrs, and secY genes through conventional PCR for sequencing. All high-quality obtained sequences were further assessed through concatenated phylogenetic analysis. A total of 25% (14/56) of febrile patients' acute blood samples were positive for Leptospira spp. High-quality sequences were obtained for only five genes, and analysis through concatenated phylogeny identified that all sequences clustered within the P1/pathogenic clade; some of them formed a robustly supported clade with Leptospira santarosai, and others were closely related with other Leptospira species but exhibited considerable genetic divergence. We describe the presence of pathogenic Leptospira species among febrile patients from the Villeta municipality and identify L. santarosai and other Leptospira species as causative agents of leptospirosis in the region.

dos Santos GF, Petri FAM, Pires GP, Panneitz AK, Braga ER, Malcher CS, Mongruel ACB, de Castro JHT, Mathias LA, de Oliveira LG. Prevalence and Risk Factors of Leptospira spp. Infection in Backyard Pigs in the State of Paraná, Brazil. Trop Med Infect Dis 2023; 8:468. [PMID: 37888596 PMCID: PMC10611261 DOI: 10.3390/tropicalmed8100468] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 09/19/2023] [Accepted: 09/25/2023] [Indexed: 10/28/2023] Open
Abstract
Leptospirosis is a zoonotic disease that poses a significant threat to human and animal health worldwide. Among different animal species, pigs are known to play a crucial role in the transmission of the pathogenic Leptospira spp. This study aimed to investigate the prevalence of Leptospira spp. infection and associated risk factors in backyard pigs in the state of Paraná, Brazil. A set of 1393 blood samples were collected from pigs on 188 subsistence properties from 136 different municipalities of the Paraná state and tested using the microscopic agglutination test (MAT) to detect antibodies against 24 different Leptospira spp. serovars. The results revealed an overall seroprevalence of 15.87% (221/1393; 95% CI: 13.95-17.78%) for Leptospira spp. antibodies, with Icterohaemorrhagiae, Butembo, and Pomona being the most commonly detected in serovar levels. The lack of rodent control (OR 1.12, 95% CI: 0.63-1.98, p = 0.02) was the only variable associated with disease incidence and was identified as a significant risk factor for Leptospira spp. infection in this context. These findings highlight the urgent need to implement effective control measures, such as improved housing conditions, rodent control, and veterinary assistance, to prevent the spread of this zoonotic disease in backyard pigs in Paraná, Brazil.

Leptospira Seroprevalence in Free-Ranging Long-Tailed Macaques ( Macaca fascicularis) at Kosumpee Forest Park, Maha Sarakham, Thailand. Infect Dis Rep 2022; 15:16-23. [PMID: 36648856 PMCID: PMC9844273 DOI: 10.3390/idr15010002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 12/08/2022] [Accepted: 12/20/2022] [Indexed: 12/28/2022] Open
Abstract
BACKGROUND Leptospirosis is a zoonotic disease that is ubiquitously distributed and is classified as a re-emerging infectious disease in humans and animals. Many serovars are carried by wildlife; all of them are capable of causing illness in humans. The purpose of this study was to investigate the prevalence of Leptospirosis in wild long-tailed macaques (Macaca fascicularis) at Kosumpee Forest Park, Mahasarakham, Thailand. METHODS A cross-sectional study was conducted at the park. Blood samples were collected via saphenous vein from 30 free-ranging long-tailed macaques. All samples were tested by the microscopic agglutination test. The LipL32 gene was used to detect pathogenic Leptospira in blood samples by conventional polymerase chain reaction. RESULTS Screening of the 30 wild macaques showed an overall Leptospira seroreactivity of 13.33%. Three of 30 macaques reacted against Leptospira serovar Shermani and one macaque was infected with Leptospira serovar Sejroe. None of the macaques presented clinical signs of leptospirosis. None of the blood samples showed the detection of the LipL32 gene. CONCLUSIONS The results indicate that the long-tailed macaques at Kosumpee Forest Park may act as natural reservoirs for Leptospirosis. Further, the results provide evidence-based information indicating that several pathogenic Leptospira serovars are circulating in the wild macaques in the study area.

Evolution of Public Health Prevention of Leptospirosis in a One Health Perspective: The Example of Mahasarakham Province (Thailand). Trop Med Infect Dis 2021; 6:tropicalmed6030168. [PMID: 34564552 PMCID: PMC8482194 DOI: 10.3390/tropicalmed6030168] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2021] [Revised: 07/27/2021] [Accepted: 08/19/2021] [Indexed: 11/24/2022] Open
Abstract
Leptospirosis is an endemic disease with moderate to high incidence in Mahasarakham province, Thailand. The present study was designed to assess the policy implementation mission regarding leptospirosis prevention and control from the national level to the local administrative levels, through a One Health perspective. A qualitative study was conducted, using documentation review, individual in-depth interviews with public health officers, local government officers, livestock officers who developed policy implementation tools or have responsibilities in leptospirosis prevention and control. The results show that Thailand has progressively developed a leptospirosis prevention and control policy framework at the national level, transferring the responsibility of its implementation to the local level. The province of Mahasarakham has decided to foster cooperation in leptospirosis prevention and control at the local level. However, there are insufficient linkages between provincial, district and sub-district departments to ensure comprehensive disease prevention activities at the local level concerning leptospirosis patients and the whole population.
