Convalescent titres were measured for 53 per cent of dogs. The most common clinical presentation was acute renal failure. Increased liver enzyme activity was documented in 22 of 36 dogs. It is clear from this study that Leptospira pomona and grippotyphosa are important pathogens capable of causing severe renal and hepatic injury in dogs. Serologic studies have been performed to evaluate the prevalence of leptospiral antibody titers in horses with and without uveitis (6, 13). Reliance on the use of serology as a means of establishing a diagnosis is uncertain, and opinions differ as to what constitutes a significant leptospiral titer.
The genus Leptospira is comprised of spiral-shaped bacteria with hooked ends. This genus, along with the genera Leptonema and Turneriella, makes up the family Leptospiraceae within the order Spirochaetales and class Spirochaetes of the proposed phylum Spirochaetes. The genus was formerly divided into two species: Leptospira interrogans, comprising all pathogenic strains, and L. biflexa. The human leptospirosis-related serologic findings in Union of Comoros are most comparable to those from neighboring Mayotte, where leptospirosis is mainly caused by serogroups Mini/Sejroe/ Hebdomadis complex, Pyrogenes, Grippotyphosa, and Pomona and where serogroup Icterohaemorraghiae is not detectable (2).
Serological Investigations Of Leptospirosis in Canada. II. Preliminary Agglutination - Lysis Studies Of Cattle Sera With Leptospira Pomona and Leptospira Canicola Antigens. Can J Comp Med Vet Sci. Jan; 21 (1):4– [PMC free article] Fish NA, Gringer I. A Report On Investigational Studies Of Bovine Leptospirosis In Ontario. Current typing of Leptospira strains requires a combination of both serological and molecular methods. Study of the epidemiology of strains within the Pomona serogroup has proved problematic due to the limitations of serological typing methods. This is particularly true of the two main complexes within this group, namely the Pomona, Monjakov, Kennewicki cluster in Leptospira interrogans.

Cross-neutralization studies on leptospiral hemolysins from strains of two antigenically different serotypes, pomona and canicola, were conducted in sheep. A third strain of serotype hardjo that does not produce hemolysin and is antigenically distinct was included for control by: 6.
Objective: Detection of anti-Leptospira antibody in serum of cattle in Ahwaz. Design: Field and serological study. Animals: cattle. The study compared the serological evidence of leptospirosis in students in four schools (veterinary, dental, advanced nursing education and pharmacy) of the University of the West Indies (UWI), by testing for IgG immunoglobulins to Leptospira spp.
using the enzyme-linked immunosorbent assay (ELISA) and the microscopic agglutination test (MAT). Overall, of students tested by the ELISA, 12 (%) and Cited by: 2.

The English summary appended to the paper is as. Follows: " The sera of imported Macacus monkeys were examined for the development of antibodies with 40 leptospiral serotypes as antigens. Positive serum reactions were only observed with 4 sera, i.e., with 2 for L. poi, and with 1 each for L.

Investigators during the period to have revealed that in Rumania leptospirosis is mainly rural and associated with pigs, affecting swineherds and persons who bathe in polluted waters.
Recently urban infections were detected in persons who handled fresh pig kidneys. A serological survey was therefore carried out on abattoir workers and 1, animals ( pigs and cattle), Serological Studies andIsolations ofSerotypehardjo and Leptospira biflexa Strains fromHorsesofArgentina DONALDM.

The most common agent of leptospirosis in sheep is Leptospira interrogans serovar hardjo, although Leptospira pomona has been isolated in some cases. 92 It is an unusual cause of abortion in sheep but should be considered in areas in which leptospirosis is a problem in cattle, pigs.
Cross-neutralization studies on leptospiral hemolysins from strains of two antigenically different serotypes, pomona and canicola, were conducted in sheep. A third strain of serotype hardjo that does not produce hemolysin and is antigenically distinct was included for control purposes.
The presence of leptospirosis in Guatemala has not been reported before although its occurrence in other Central American countries is well known [see ALEXANDER, Bull.
World Health Organization,v. 23, ; this Bulletin,v. 35, ()]. Recent efforts to develop the livestock industry in Guatemala prompted the serological survey reported here. A cross-sectional serological survey was conducted during January to August to determine the seroprevalence of Leptospira serovars in five species of livestock in Thailand and to identify associations between seropositivity and sex, age, species and geographical locations.
Sera from livestock ( cattle, buffaloes, pigs, sheep, goats) from 36 provinces. A serological survey done in (Azevedo, ) obtained a low percentage (%) of leptospiral titres – to serovars Tarassovi (%), Ballum (%) and Pomona (%).
The purpose of the present study was to detect renal infection and leptospiral antibodies in a population of horses slaughtered at abattoirs in the Lisbon area.
The clinical findings, which included a single abortion, were suggestive of leptospirosis and serological studies indicated that a serotype other than the usual L. pomona was the causative agent.
A fastidious leptospire recovered from the urine of one cow has been identified as L. hardjo, a member of the hebdomadis group.

We determined the frequency of isolation of Leptospira from dogs and rodents, the serovars of Leptospira, and the clinical, gross and histological manifestations in dogs with leptospirosis in dogs, samples of urine, blood and kidney were collected while only kidney and blood samples of trapped rodents were used.
Although serologic data indicate horses in N. America are exposed to a variety of leptospiral serovars, abortion is almost always associated with Leptospira interrogans serovar Pomona type kennewicki.
A variety of wildlife including raccoons, white tailed deer, striped skunks, opossums, and red and grey foxes have been shown to host serovar Pomona and have therefore been suspect as .A number of Leptospira serovars (mainly grippotyphosa, pomona and bratislava) have been implicated in the pathophysiology of ERU in Europe and the USA 3, 6, 8, 12, It is commonly believed that Leptospira infection is not a major factor in the aetiology of ERU in horses in the UK
