Leptospira noguchii is a current zoonotic pathogen in Brazil. Here, we report the draft genome sequence of the Brazilian L. noguchii serogroup Panama strain U73, isolated from asymptomatic cattle urine.

In the present work, we announce the draft genomes for three new strains (U160, U164, and U233) of Leptospira santarosai, isolated from urine samples from asymptomatic cattle in Rio de Janeiro, Brazil.

Leptospirosis is a zoonosis of worldwide distribution, caused by Leptospira interrogans and is considered as an emerging global public health problem. Transmission usually results from direct or indirect exposure to the urine or other body fluids of leptospiruric animals which may become a source of infection for human or other animals. Having a humid climate with plenty of annual rainfall, Gui...

Leptospirosis is a worldwide distributed zoonosis which has long been endemic in Thailand. Cattle and buffaloes are important livestock species that live in close contact with humans, especially in rural areas. These animals may, therefore, act as long-term carriers of leptospirosis for humans and other livestock species. The present study employed loop-mediated isothermal amplification (LAMP) ...

Industrialization, economic and population growth rates in Ghana have increased the release of contaminants including polycyclic aromatic hydrocarbons (PAHs) into the environment through which humans and animals are exposed. Cattle is reported to be exposed to high levels of PAHs through feed and inhalation. Once exposed, PAHs are metabolized and excreted in urine, feces or bile. In a previous ...

Twenty-four cross bred steers (BW 452.5 +/- 15.5 kg) were used to evaluate nutrient excretion and odorous compounds in urine and feces of feedlot steers fed diets containing corn wet distillers grains with solubles (WDGS). Cattle were weighed, blocked by BW, and assigned randomly to 1 of 4 dry-rolled corn-based diets containing 0, 20, 40, or 60% WDGS (DM basis). A 96-h total fecal and urine col...

Concentrated animal feeding operations are major sources of ammonia to the atmosphere. Control methods to reduce emissions include acidifying amendments, urease inhibitors, and absorbents. For beef cattle, decreasing crude protein (CP) in diets may be the most practical and cost-effective method to reduce ammonia emissions. Our objective was to quantify the effect of reducing CP in beef cattle ...

We read with interest the study reported by Ayral and others entitled “Distribution of Leptospira serogroups in cattle herds and dogs in France.” Ayral and others concluded that the inventory of infecting Leptospira serogroups revealed that current vaccines in France are not fully capable of preventing leptospirosis. In total, 394 cattle were diagnosed with clinical leptospirosis, and the resul...

background and objectives: leptospirosis is an important zoonotic disease caused by leptospira interrogans . leptospirosis leads to economical losses in dairy farm industry. the objective of this study was to evaluate the pathogenic serovars of leptospira interrogans in dairy cattle herds of shahrekord by pcr. materials and methods: two hundred samples (100 urine and 100 blood) were collected f...
