Prevalence of Anaplasmosis in cattle in Sirajganj district of Bangladesh

Abstract

An epidemiological investigation was conducted to ascertain the prevalence of anaplasmosis in cattle in Sirajganj district of Bangladesh, during the period of December 2013 to November 2014. During one year study period a total of 395 cattle were examined, and where 102 were found to be infected with Anaplasma spp. On Geimsa stained blood smear examination, it was observed that the overall prevalence of anaplasmosis in cattle was recorded as 25.82%. The effect of area, age, sex, breed and season was observed in cattle during this study. The highest prevalence (34.19%) was reported in the older cattle (> 3 years of age) and the prevalence was higher in female (28.88%) than male (19.20%). All crossbred cattle was showed higher prevalence than local cattle. The prevalence of anaplasmosis infection was noticed as the highest in the rainy season (30.68%) in relation to summer (27.50%) and winter (15.15%) season. From the study it was evident that cattle were infected with the organism and caused a serious economic loss which will assist to take necessary preventive interventions.

Molecular identification of tick-borne pathogens infecting cattle in Mymensingh district of Bangladesh reveals emerging species ofAnaplasmaandBabesia

“…Anaplasma marginale was the fourth most prevalent TBP detected in this study. The prevalence of A. marginale recorded here is consistent with the previous findings reported from different region of the country (Alim et al., ; Belal et al., ; Chowdhury et al., ; Rahman et al., ). A. marginale has a worldwide distribution and is considered to be the most prevalent TBPs causing high morbidity and mortality of cattle in subtropical and tropical countries (Kocan, de la Fuente, Blouin, Coetzee, & Ewing, ).…”

“…Microscopic examination of Giemsa‐stained thin blood smears revealed that eighteen slides were positive (4.7%, 18/384) for Anaplasma spp., supporting previous reports in Bangladesh (Alim et al., ; Belal et al., ; Chowdhury et al., ). None of the smears was found to be positive for Babesia and Theileria species, which can be explained by the low sensitivity of this technique in combination with typically low parasitemia in healthy carrier animals (Salih, El Hussein, Seitzer, & Ahmed, ).…”

“…Anaplasma bovis was the second most prevalent TBP detected in this study with an estimated prevalence of 35.7% and is here recorded for the first time from cattle in Bangladesh. Previous studies identified only A. marginale and A. centrale by microscopic examination of Giemsa‐stained blood smears (Alim et al., ; Belal et al., ; Chowdhury et al., ; Rahman et al., ). A. bovis is usually associated with subclinical anaplasmosis, and little is known about its epidemiology (Ooshiro, Zakimi, Matsukawa, Katagiri, & Inokuma, ).…”

“…So far, a small number of tick species have been identified from different parts of Bangladesh infesting livestock, namely Rhipicephalus microplus, Haemaphysalis bispinosa, Rhipicephalus sanguineus, Hyalomma anatolicum, Hyalomma truncatum and Amblyomma testudinarium (Ghosh et al, 2007;Islam, Alim, Tsuji, & Mondal, 2006;Kabir et al, 2011). The occurrence of the causative agents of bovine babesiosis, anaplasmosis and theileriosis has also been reported all over the country (Al Mahmud, Belal, & Hossain, 2015;Alim et al, 2012;Belal, Al Mahmud, & Ferdous, 2015;Chowdhury, Hossain, Barua, & Islam, 2006). However, diagnosis of these TBPs is mainly based on the examination of Giemsa-stained thin blood smears from clinically infected animals.…”

Epidemiology and molecular detection ofAnaplasmaspp. in goats from Chattogram district, Bangladesh

“…Even though statistically not significant, there was more anaplasma infection found in female (16.19%) than the male goats (15.23%) which was consistent with Yousefi et al (2017) in goats and Belal et al (2014) in cattle. They reported that females were more susceptible to anaplasmosis because of stress and insufficient supply of feed during high demand in pregnancy (Kamani et al, 2010).…”
