“…Bacteriological identification as shown in table (5) revealed that 27 (81.8 %) out of 33cattle showing visible lesions were identified as M. bovis. The recovery rate of M. bovis is near to the results that obtained by Tammemagi et al (1973) (89.1 %); Naglaa (2008) (70.59 %) and Rabab (2008) (80 %). Other investigators reported lower M. bovis recovery rate, Akeulah (1981) (32.7 %); Gallo et al (1983) (5.5 %).…”

A definitive diagnosis of M. bovis infection in animals depends on the isolation of the organism, as the optimum condition for the primary isolation of M. bovis infection has not been determined. In this study a total number of 2550 cattle from different governorates in Egypt were tested by Single Intradermal Cervical (SID) tuberculin skin test. Positive reacted cattle (no= 42, 1.6%) were slaughtered and suspected lesions were collected, these samples were decontaminated by using three different methods, which were 0.75 % Hexadecyl Pyridinium Chloride (HPC), 5% oxalic acid and 6 % sulphuric acid. Isolation of mycobacteria from 42 samples by using these decontaminated methods were of 34 (80.9 %), 30 (71.4 %) and 28 (66.6 %), respectively. So it could be concluded that using HPC method as decontaminated agent revealed high rate of isolation of mycobacteria with less contamination (7.1 %) than the other two methods.

“…It has been demonstrated that the pre-scapular lymph node receives afferent vessels from the skin enclosing the neck and shoulder and even muscles like the prescapular muscle (Henderson, 1946;Sisson and Grossman, 1938). These findings are consistent with those of other studies where it was also observed that lymph nodes are the organs in cattle most frequently affected by tuberculous lesions (Tammemagi et al,, 1974;Lepper and Pearson, 1973;Corner, 1994). It is significant to note that, macroscopic or visual inspection pre-culture revealed that a high number of lymph nodes harboured gross lesions that is, 115 lymph samples (or 74.2%) out of 155 samples.…”

Despite its existence in Ghana, there is very little information on the extent or nature of bovine tuberculosis. This state of affairs may pose a serious public health threat through risks associated with the consumption of beef from infected cattle, dairy milk and other bovine products. A study to screen bovine carcasses with lesions suggestive of mycobacterial infection at necropsy in three selected abattoirs in Accra was conducted. A total of 2,886 cattle slaughtered in 3 abattoirs in the Greater Accra Region of Ghana between June and October, 2009 were examined at necropsy for lesions suggestive of bovine tuberculosis. Specimens taken from suspicious lesions were first subjected to Ziehl-Neelsen microscopy and then cultured on Löwenstein-Jensen media containing both pyruvate and glycerol. One hundred and fifty five (155) tissue samples were elicited from only lesions presenting with classical patho-morphological features consistent with bovine tuberculosis in organs found in 145 cattle. These results indicate that 5% (or 145/2886) of the cattle carcasses inspected at slaughter in the Accra region exhibited lesions suggestive of bovine tuberculosis and this poses a serious public health threat. Visual inspection at necropsy, provided done proficiently, could serve as the primary screening measure for beef contaminated with mycobacterial species in abattoirs in resource-poor settings. Microscopic examination, because of its revealed high specificity in this work may be employed, only as a supplementary test, in difficult cases.

“…From a total of 90 carcasses, 55 positive cultures were recovered with an isolation rate of 61.1 %. The obtained results were less than that mentioned by (Tammemagi, et al, 1973), 89.1 % and (Naglaa, 2008), 70.59 %. Other investigators reported lower M. bovis recovery rate, by (Adawy, 1986), 17.5 % and (Zschoc, et al, 1990), 1.6 %.…”
