“…This overall prevalence (25-5 %) is much higher than that reported by Wisseman et al (1955) and Joseph (1979). Results from this present study record the presence of agglutinating antibodies to the ten leptospiral serovars tested (Table 1) and it must be emphasized here that the serological results obtained were only serogroup-specific.…”

“…Thus, it was shown that serovars hardjo and tarassovi were the two serovars affecting the buffaloes in this study. Earlier reports (Gordon-Smith et al 1961;Wisseman et al 1955) in Malaysia showed much lower prevalence of leptospiral infection in buffaloes. In the Philippines, Carlos et al (1970) demonstrated a high prevalence of leptospiral infection in the buffaloes.…”

“…The first report of leptospirosis in domestic animals in Malaysia was a case in a dog (Fletcher, 1928), and the earliest attempt to examine the prevalence of 380 Leptospira in animals in West Malaysia leptospiral infection in domestic animals in Malaysia was that conducted by Wisseman et al (1955). The number of animals examined was quite small and the results obtained were apparently not truly representative of the disease occurrence.…”

SUMMARYA cross-sectional serological survey of domestic animals in West Malaysia revealed that % of the animals examined had agglutinating antibodies to one or more antigens belonging to Leptospira interrogans. Significant prevalence of infection was observed in cattle (405 %), buffaloes (31 %) and pigs (16%). The Sejroe serogroup was shown to be the principal one involved in cattle and buffaloes, and to a lesser extent the Tarassovi and Pomona serogroups. Evidence of infection in domestic animals by strains bearing the other seven antigens appeared insignificant and was indicative of sporadic infection. A majority of the large (semi-intensive) cattle and buffalo farms demonstrated a high prevalence of leptospiral infection. In both species of domestic animals mentioned above, the prevalence of infection was significantly higher (P = 0O01) in the semi-intensive farms than in the smallholdings. Amongst cattle, the droughtmasters had the highest prevalence whilst the Kedah-Kelantan (an indigenous breed) had the lowest prevalence of leptospiral infection. In general, the temperate breeds of cattle had a significantly (P = 0O01) higher prevalence of infection than local breeds. Leptospiral infection in goats and sheep was shown to be sporadic, and the Pomona serogroup was the principal leptospiral serogroup involved in these small ruminants. The prevalence of infection in pigs was observed to decline during the study period, and it is suspected that pigs in West Malaysia are the maintenance host for serovar pomona whilst cattle are the maintenance host for serovar hardjo.Overall, it appears that domestic animals in Malaysia will play a bigger role in the epidemiology of leptospiral infection with the advent of sophisticated farming.

“…2,3 Rodents, especially rats, are considered to be the most important reservoirs or maintenance hosts of Leptospira . 3,4 Pathogenic leptospires that infect these maintenance hosts persist in their kidneys causing either slight or no harm. However, they cause mild to severe illness, and even death to susceptible hosts such as humans and other animals (also called accidental or incidental hosts).…”

Abstract. Rats are known to be the most important reservoirs and transmission sources of leptospirosis. However, the status of leptospirosis in the Philippines regarding reservoirs and transmission remains unknown. A survey was conducted in Metro Manila and Laguna that analyzed samples obtained from 106 rats. Using the microscopic agglutination test, we found that 92% of rat serum samples were positive for anti-Leptospira antibodies; the most common infecting serovars were Manilae, Hebdomadis, and Losbanos. On the basis of pulsed-field gel electrophoresis and gyrase B gene sequence analyses, four groups of rat kidney isolates were found: L. interrogans serovar Manilae, serovar Losbanos, and serogroup Grippotyphosa, and L. borgpetersenii serogroup Javanica. Most isolates were lethal after experimental infection of golden Syrian hamsters. Results showed that these four Leptospira serovars and serogroups are circulating among rats, and that these animals may be one of the possible transmission sources of leptospirosis in the Philippines.

“…;Famatiga et al, 1972). Rodents, especially rats, are considered to be the most important reservoirs or maintenance hosts of Leptospira (Wisseman et al, 1955;Faine et al, 1999). Leptospira spp., likely to be transmitted by urban commensal rodents, are emerging as serious threats to public health in many large cities in China (Liu et al, 2012).…”
