Abstract
We sought to investigate whether SARS-CoV-2 was present, and to perform full-length genomic sequencing, in a 5-year-old male crossbreed dog from Gaborone, Botswana that presented overt clinical signs (flu-like symptoms, dry hacking cough and mild dyspnoea). It was only sampled a posteriori, because three adult owners were diagnosed with SARS-CoV-2 infection. Next-generation sequencing based on Oxford Nanopore Technology (ONT) was performed on amplicons that were generated using a reverse transcriptase real-time polymerase chain reaction (RT-qPCR) of confirmed positive SARS-CoV-2 nasopharyngeal and buccal swabs, as well as a bronchoalveolar lavage with mean real cycle threshold (qCt) value of 36 based on the Nucleocapsid (N) gene. Descriptive comparisons to known sequences in Botswana and internationally were made using mutation profiling analysis and phylogenetic inferences. Human samples were not available. A near-full length SARS-CoV-2 genome (∼90% coverage) was successfully genotyped and classified under clade 20 O and Pango-Lineage AY.43 (Pango v.4.0.6 PLEARN-v1.3; 2022-04-21), which is a sublineage of the Delta variant of concern (VOC) (formerly called B.1.617.2, first detected in India). We did not identify novel mutations that may be used to distinguish SARS-CoV-2 isolates from the dog and humans. In addition to Spike (S) region mutation profiling, we performed phylogenetic analysis including 30 Delta sequences publicly available reference also isolated from dogs. In addition, we performed another exploratory analysis to investigate the phylogenetic relatedness of sequence isolated from dog with those from humans in Botswana (n = 1303) as of 31 March 2022 and of same sublineage. Expectedly, the sequence formed a cluster with Delta sublineages - AY.43, AY.116 and B.1.617.2 - circulating in same time frame. This is the first documented report of human-associated SARS-CoV-2 infection in a dog in Botswana. Although the direction of transmission remains unknown, this study further affirms the need for monitoring pets during different COVID-19 waves for possible clinically relevant SARS-CoV-2 transmissions between species.

Abstract
Contagious bovine pleuropneumonia (CBPP), caused by Mycoplasma mycoides mycoides biotype small colony (SC) (MmmSC) appears to be making a serious comeback in Africa after successful control programs in many parts of the continent during the 1960s and 1970s. Botswana, a country that has been free from the disease for more than 50 years, was affected in 1995. An eradication policy was adopted by the Government of Botswana in which 320,000 cattle in the affected district of Ngamiland, Northwestern Botswana were slaughtered. This was followed by a restocking exercise in which 70,000 cattle were sent to the outbreak areas as replacement stock. It became necessary to carry out serosurveillance in order to ensure that the disease did not reenter Botswana and to ensure that the replacement stock remained free from the disease. The specificity and sensitivity of the complement fixation test (CFT) in Botswana was assessed in 82 cattle affected by the disease and held in a double fenced quarantine camp. The newly developed competitive ELISA was made available to the National Veterinary Laboratory (NVL) through the FAO/IAEA Joint Division in Vienna, Austria. Using postmortem lesions as the gold standard and a 2 x 2 contingency table, the two tests were compared in terms of their sensitivity and specificity in detecting antibodies to MmmSC. The CFT was found to be slightly more sensitive than the c-ELISA, and this could be related to the stage of the disease. A long-term study comparing the progression of the disease with the two tests is, therefore, essential.
