“…Concerning to the reproductive experience the observed results in this study are similar to the ones seen by Larson and Hays (1958) and Dixon, Hart and Fouts (1961). According to these authors an important source of variation of the levels of immunoglobulin in colostrum is related to the reproductive experience, considering that primiparous dairy cattle usually produce an inferior quality of colostrum.…”

“…In milk dairy cattle due to specialization it was showed that migration of serum immunoglobulin to the mammal glands, during the formation of colostrum, determines a decrease in concentration of this protein in the blood stream, in the last weeks of peripartum (DIXON; HART;FOUTS, 1961). In this study high production dairy cattle had less quantity of circulating antibodies in all physiological phases.…”

Anaplasma marginale is the most prevalent pathogen of cattle transmitted by ticks in the world. This study aimed to evaluate the risk factors for anaplasmosis in dairy cattle. Fifty dairy cattle from the herd of Empresa de Pesquisa Agropecuaria do Estado do Rio de Janeiro were selected by proportional stratified sampling. The risk factors evaluated were: physiological state, race pattern, number of lactations, milk production, infestation by Rhipicephalus microplus and animal density. Antibody activity against A. marginale was determined using the indirect enzyme-linked immunosorbent assay. The percentual values of seroprevalence for A. marginale were submitted to χ2 test, and the level of minimum significance, to keep a factor in the model of logistic regression, was fixated in 5%. It was observed that pregnancy and lactation influenced significantly (p<0.05) in the seropositivity of the animals. Bos indicus animals had 5.21 times more chances of being seropositive than B. taurus animals. Primiparous female had 88% more chances of being seropositive than pluriparous female. Animals with high milk production were 63% more positive than low production animals. When infested by ticks the animals had 39% more chance of being seropositive to A. marginale. Bos indicus animals presented 5.21 times more chance of being seropositive than B. taurus animals. Primiparous females presented 88% more chance of being seropositive than the pluriparous ones. High milk production animals were 63% more positive than the low production ones. When infested by ticks the animals had 39% more chance of being seropositive to A. marginale. High density grazing provided for the animals 3.2 times more chances of being seropositive than low density ones. The herd was classified as erratic to A. marginale, even being placed in a steady enzootic area.

Foram selecionadas por amostragem estratificada proporcional 50 vacas do rebanho da Empresa de Pesquisa Agropecuária do Estado do Rio de Janeiro. Os fatores de risco avaliados foram: estado fisiologico, padrão racial, número de lactações, produção leiteira, infestação por Rhipicephalus microplus e densidade animal. A atividade de anticorpos contra Anaplasma marginale foi determinada utilizado o Ensaio de Imunoadsorção Enzimático Indireto. Os valores percentuais de soroprevalêcia para A. marginale foram submetidos ao teste χ2, sendo que o nível de significância mínima para manter um fator no modelo de regressão logística foi fixado em 5%. Observou-se que, tanto a gestação quanto a lactação influenciaram significativamente (p<0.05) na soropositividade dos animais. Animais Bos indicus apresentaram 5,21

“…For Model J, we assume all cattle have exactly the same susceptibility to infection of Bovine Babesiosis. However, it is important to note that it is known in the literature that the B. indicus breed of cattle is more highly resistant than the B. taurus breed to Bovine Babesiosis caused by B. bigemina and B. bovis (Bock et al 1999a). This is addressed in subsequent models in Sects.…”

Models of Bovine Babesiosis Including Juvenile Cattle

Bovine Babesiosis in cattle is caused by the transmission of protozoa of Babesia spp. by ticks as vectors. Juvenile cattle (<9 months of age) have resistance to Bovine Babesiosis, rarely show symptoms, and acquire immunity upon recovery. Susceptibility to the disease varies between breeds of cattle. Models of the dynamics of Bovine Babesiosis transmitted by the cattle tick that include these factors are formulated as systems of ordinary differential equations. Basic reproduction numbers are calculated, and it is proved that if these numbers are below the threshold value of one, then Bovine Babesiosis dies out. However, above the threshold number of one, the disease may approach an endemic state. In this case, control measures are suggested by determining target reproduction numbers. The percentage of a particular population (for example, the adult bovine population) needed to be controlled to eradicate the disease is evaluated numerically using Columbia data from the literature.

“…However, these strategies are often ineffective and therefore some diseases persist (Cordes and Carter, 1979;Bumstead and Barrow, 1993;Rossetti et al, 2011). Several studies have demonstrated various degrees of resistance or susceptibility of Zebu and European breeds to diseases such as trypanosomiasis, ectoparasitic infestations, and gastrointestinal parasites (Rechav and Kostrzewski, 1991;Wambura et al, 1998;Bock et al, 1999;Naessens et al, 2002). However, little is known about how mechanisms of cellular and humoral immunity differ between Zebu and European breeds, which may be related to differences in resistance or susceptibility to infectious or parasitic diseases.…”

ABSTRACT. Differences in cellular and humoral immunity in Zebu (Bos taurus indicus) and European (B. taurus taurus) cattle breeds, which may be related to differences in resistance or susceptibility to infectious or parasitic diseases, are largely unknown. This study aimed to perform a comparative analysis of innate and adaptive immunity of European (including Holstein, Brown Swiss, and Hereford) and Zebu (including Gir, Nelore, and Guzera) breeds, by assessing their peripheral blood leukocyte profiles (i.e., monocytes, eosinophils, and lymphocytes, including CD4 + and CD8 + T cells, and CD21 + B cells). Phenotypic profile of peripheral blood bovine leukocytesHigher frequencies of cells involved in innate immunity were observed in Zebu breeds, particularly monocytes and non-T and non-B cells (13.37 ± 0.9058 and 37.67 ± 1.55, respectively). This finding may contribute to the increased resistance of B. taurus indicus to certain infectious and parasitic diseases. Considering other leukocyte populations in the peripheral blood, among-breed variation was greater than differences between the two subspecies. This study will serve as a basis for further investigations regarding comparative immunology and resistance to infectious and parasitic diseases of cattle.
