“…The leptospirosis in ruminants, although clinically not important, causes huge economic losses and is considered a major plague of livestock farming. Indeed, the involvement of the leptospirosis in the abortion of ruminants is largely recognized (Smith & Easmon ), venereal transmission of the bacterium has been demonstrated and the occurrence of mastitis, associated with leptospirosis, has been described (Simegnew ; Garoussi et al ).…”

A serological study was carried out in two Senegalese villages located in the Sine‐Saloum region in order to estimate the presence of anti‐leptospiral antibodies in humans and animals, and to identify the predominant serogroups. Seven hundred and forty‐nine serum samples were collected from humans (n = 545), dogs (n = 33), donkeys (n = 20), goats (n = 52), sheep (n = 43) and N’Dama cattle (n = 56), all originated from Dielmo and Ndiop villages. All samples were tested for different serovars of pathogenic Leptospira species by the microscopic agglutination test. Considering titres ≥ 1:100, 7.7% [CI 95:5.5 to 9.9] on the 545 human blood samples tested and 42.2% [CI95:35.4 to 48.9] on the 204 animal blood samples tested were found to be positive to one or more serovars. The results obtained indicate that the Australis serogroup is the most prevalent serogroup in human (67.3%) and cattle (27.3%). Serogroup Icterohaemorhagiae is the most frequent serogroup in goat (55.6%) and donkey (37.5%). Canicola (23.4%), Icterohaemorhagiae (21.1%) and Australis (12.5%) serogroups are the most prevalent serogroups in dogs. This study shows that diverse Leptospira serovars occur in a wide range of wild and domestic mammal species, as well as in humans in Senegal. However, further studies are needed to better understand the complexity of Leptospira epidemiology in Africa, identify the reservoirs of different serogroups and estimate its impact on livestock. Understanding the multi‐host epidemiology of leptospirosis is essential to control and prevent the disease.

B ovine milk is a source of nutrition for people and calf since it contains the supplements necessary for growth and progress of the calf. It could be a source of lipids, proteins, amino acids, minerals and vitamins. It contains immunoglobulins, hormones, growth factors, cytokines, nucleotides and peptides (Haug et al., 2007). Raw bovine milk is considered as a suitable growth medium for the multiplication of nearly all kinds of microorganisms (Kumar et al., 2010; Mahmoud et al., 2019). Bovine milk is considered as a vehicle for many infectious bacterial diseases. The most common infectious bacterial diseases that spread via bovine milk to young calves and human are bovine tuberculosis, brucellosis, mycoplasma infection, leptospirosis, and Q fever.

“…Já no útero gravídico, as leptospiras geram uma infecção da placenta, atravessam-na e atingem o feto, provocando a morte do animal e sua eliminação (RADOSTITS et al, 2002), sendo possível a detecção da bactéria em amostras destes abortos (GENOVEZ et al, 1993;LANGONI et al, 1999;RICHTZENHAIN et al, 2002). HIGGINS et al, 1980), e a prevalência aparenta ser maior em multíparas do que em primíparas (GAROUSSI et al, 2017). Nesta síndrome, há acentuada diminuição na produção de leite, o qual demonstra coloração amarelada de consistência similar ao colostro, presença de grumos, sangue e elevada contagem de células somáticas (ELLIS, 1984;FAINE et al, 1999).…”
