Infection ecology & epidemiology, 2018
Background: Brown rats (Rattus norvegicus) may carry pathogens that can be a risk for public health. Brown rats in the Netherlands were tested for the zoonotic pathogens Leptospira spp. and Seoul hantavirus (SEOV), in order to obtain insight in their prevalence. Methods and results: Cross-sectional studies were performed at four locations from 2011 to 2015. The rats were tested for Leptospira spp. using real-time PCR and/or culture resulting in a prevalence ranging between 33-57%. Testing for SEOV was done through an adapted human Seoul hantavirus ELISA and realtime RT-PCR. Although at several locations the ELISA indicated presence of SEOV antibodies, none could be confirmed by focus reduction neutralization testing. Conclusion: The results indicate a widespread presence of Leptospira spp. in brown rats in the Netherlands, including areas with a low leptospirosis incidence in humans. No evidence for circulation of SEOV was found in this study.

Hantavirus infections in humans and commensal rodents in Singapore
Transactions of the Royal Society of Tropical Medicine and Hygiene
To determine the extent of hantavirus infection in Singapore, serological studies using the indirect immunofluorescent antibody (IFA) test were conducted on commensal rodents and on human patients in 4 diagnostic groups. Virus isolation using a Vero E6 cell line was performed on hantaviral antigen-positive rodent lung tissue. Of 142 rodents and 3 insectivores studied, 37 (26%) were seropositive for IFA. Rattus norvegicus was the predominant species captured, with the highest species-specific seropositive rate of 32% (36 of 113). A hantavirus strain, R36, was isolated from one R. norvegicus. Seropositive rates for human patients were: 8% respectively for dengue haemorrhagic fever suspects and for non-A non-B hepatitis patients, 3% for leptospirosis suspects and 2% for acute nephritis patients. 2 patients had marked liver dysfunction but mild renal involvement. This hepatitis-like manifestation appears to be a clinical variant of hantavirus infection.

A serological survey has been carried out to detect evidence of hantavirus infection in rodents from two provinces of Thailand. This study aimed to examine virus antibody in 354 rodents trapped among 6 different villages of Nakhon Pathom Province (February-March, 1998) and in 326 rodents trapped among 14 villages of Nakhon Ratchasima Province (August-October, 1998). Seroprevalence among rodents from Nakhon Pathom Province (2.3%), was mostly find in Rattus norvegicus (3.8%) and Bandicota indica (2.6%). In Nakhon Ratchasima Province seroprevalence (4.0%) was mostly in Bandicota indica (19.1%) and Rattus exulans (3.5%).
A newly recognized hantavirus in the Asian house rat (Rattus tanezumi) in Indonesia
Journal of General Virology, 2009
Hantaviral sequences were recovered from the lung tissue of an Asian house rat (Rattus tanezumi) captured in Serang, Indonesia. Phylogenetic analysis of partial L, M and S segment sequences showed that they belonged to a novel hantavirus provisionally named Serang virus (SERV). Notably, SERV is distinct from the hantaviruses associated with rodents of the species Rattus: Seoul virus associated with Rattus norvegicus worldwide and Gou virus isolated from Rattus rattus in China. Instead SERV appeared more closely related to Thailand virus (THAIV) carried by the great bandicoot rat (Bandicota indica). These results suggest the possibility that SERV originated via host-switching, with a possible scenario of (pre)-THAIV 'jumping' from (pre)bandicoots to rats and colonizing this new host species.
Serological Evidence of Hantavirus Infection in Laboratory Rats and Personnel
International Journal of Epidemiology, 1988
Hantaviruses are established causative agents of hemorrhagic fevers and renal diseases amongst other clinical manifestations in humans, with most diagnosis based on serological assays. The disease, which is rodent-borne, has been reported in numerous countries worldwide but information about the disease is scanty in the Caribbean. The objective of this investigation is to determine the frequency of exposure to hantaviruses in a selected apparently healthy human population associated with abattoirs and livestock farms in Trinidad using a hantavirus immunoglobulin G (IgG) enzyme-linked immunosorbent assay (ELISA). Of a total of 236 individuals tested, 27 (11.4%) were seropositive for hantavirus infection. Amongst abattoir workers the frequency of infection was 9.4% (6 of 64) compared with seropositivity rate of 12.4% (18 of 145) and 11.1% (3 of 27) amongst livestock farm workers and office workers and other individuals with minimal animal contact respectively. The differences were, however, not statistically significant (p > .05; χ 2 test). Age, gender, and race did not significantly affect the infection rate by hantavirus in the workers studied. This is considered the first documented evidence of hantavirus infection in Trinidad and Tobago. It is imperative for local physicians to consider hantavirus as a differential diagnosis in patients with hemorrhagic fever and renal diseases, since there may be a number of undiagnosed cases of hantavirus disease in the human population in the country.

Leptospirosis is a zoonotic disease that occurs globally. Leptospires are transmitted through the urine of infected mice, through injured skin or mucosal invasion. Infection can occur through direct contact or through contact with contaminated water or soil. This qualitative research uses a combination of epidemiological studies with a case study approach. Rat urine metabolism samples will be tested by testing the base pair chain through the Polymerase Chain Reaction method for leptospirosis. Electrophoresis results showed 5% percent of positive samples with 330 bp. The conclusion of this study, the molecular identification of leptospirosis from rat urine using the Polymerase Chain Reaction technique are found positive results so prevention is needed to control the distribution of pathogenic leptospirosis bacteria. Urban rats (Rattus rattus) in leptospirosis transmission are considered as the most important leptospira reservoir, because high population densities of this species can cause an increase in the spread of leptospirosis.
Microbiological and epidemiological review of Hantavirus: A Review
Al-Anbar Journal of Veterinary Sciences
Hantaviruses are rodent viruses that have a world-wide distribution. Rodents and insectivores act as asymptomatic, chronic, persistently infected carrier hosts, whereas humans are dead end hosts and may exhibit symptoms after an incubation period of between one and six weeks. Hantaviruses infect humans and causing either hemorrhagic fever with renal syndrome (HFRS) or Hantavirus cardiopulmonary syndrome (HCPS). Due to the absence of the treatment and approved vaccine in the USA, European and Asian countries, the public awareness and precautions are the only way of minimizing the risk of Hantavirus infection. This review provides a microbiological and epidemiological summary of the Hantavirus diseases in rodents and human beings. We concluded that the disease is a serious zoonotic disease the affect animals and humans and the mortality rate is really high. A wide range of different diagnostic tests play an important role in the diagnosis of the Hantavirus.
