A longitudinal study of animal and human rabies covering 18 years from 1989 to 2006 was retrospectively conducted in order to highlight the epidemiological features and trends of the disease in Botswana. Over the 18-year period, a total of 4 306 brain specimens collected from various species of animals including human beings with clinical signs consistent with rabies were submitted to the National Veterinary Laboratory in Gaborone for confirmatory diagnosis. Of the samples submitted, 2 419 cases were found to be positive for lyssavirus antigen; this presents an overall prevalence rate of 56.18 ± 1.48 %. About 85.7 % (2 074/2 419) of the cases were from domestic animals, 14.2 % (343/2 419) cases were from wild animals and two cases (0.1 %) were from human beings. During the first half of the study (1989-1997) the prevalence rate of the disease was estimated at 62.79 ± 1.85 % (1 645/2 620 positive) whereas during the second half (1998-2006) it was estimated at 45.91 ± 2.38 % (774/1 686 positive) and the difference between the two estimates was statistically, highly significant (Δ % = 16.88, SE 95) diff % = 3.015, SD = 5.599; P < 0.001). Ruminant rabies accounted for 79.99 % (50.92 % bovine, 28.40 % caprine and 0.67 % ovine) whereas canine (domestic dog) and feline (domestic cat) accounted for 16.01 and 0.87 %, respectively. Equine rabies accounted for 3.13 % with 1.35 and 1.78 %, respectively, for horses and donkeys. Jackal rabies accounted for more than 60 % of the total cases in wild animals. These findings are discussed in relation to the previous epidemiological situation of the disease (1979-1988), its socio-economic impact, monitoring and control in Botswana.

Malassezia pachydermatis (M. pachydermatis) is a fungus of importance in human and veterinary medicine. Although a part of the normal microbiota, it can sometimes be present in its pathogenic form, particularly causing otitis and dermatitis in animals. Among human beings, it mainly affects immune compromised patients and newborns, causing simple pustulosis, seborrheic dermatitis, tinea versicolor or fungemia. This study aimed to analyze the genomic polymorphism in M. pachydermatis samples isolated from Canis familiaris (domestic dog), Felis catus (domestic cat), and Myrmecophaga tridactyla (giant anteater). Two hundred and fourteen samples were collected and cultured in Sabouraud agar with chloranphenicol (100mg L-1) and incubated at 37 °C for a period of 7 to 10 days. One hundred and sixty six samples that appeared morphologically comparable to yeast cultures were processed for DNA extraction and PCR was performed for a specific region in the Internal Transcribed Spacer (ITS) of M. pachydermatis. Among these, seven (4.21%) were negative and 159 (95.79%) were positive. Of the 159 positive samples, 102 (64.15%) were from animals with clinical signs and 57 (35.85%) without clinical signs. Fifty-seven samples were selected at random for RAPD-PCR based genotyping and distributed into four genetic groups. Types I and II were more frequent in animals with clinical signs while type III was frequent in healthy animals. Type IV occurred evenly across animals with or without clinical signs. These results indicate differences in pathogenicity of the fungus based on the genotype.

Rabies in human beings is always fatal. The commonest source of human infection is the domestic dog, which in turn is infected by wild carnivorous animals. As a result of the widespread outbreak of rabies in recent years in Europe, Asia, Africa and the Americas there have been demands for wholesale slaughter of certain wild animals. The recently published fifth report of the World Health Organisation (WHO) Expert Committee on Rabies recommends control of certain vector species. The danger, as Michael Woodford points out in this assessment of the report, is that the methods used will almost certainly involve the killing of other harmless wildlife.

In this paper the pathological and the bacteriological findings in ten instances of naturally acquired tuberculosis in ten different species of animals are recorded. The tubercle bacilli obtained in culture from five species (bat, bear, bison, hedgehog and mink), all cases of fatal tuberculosis, were of the bovine type. The bacilli from a case of localised glandular tuberculosis in a goat and one of tuberculosis of the pancreas in a kangaroo were of the avian type. The bacilli from a case of generalised retrogressive tuberculosis in a horse, of minimal thoracic tuberculosis in a calf and cutaneous and glandular tuberculosis in a parrot were of the human type. These results amplify the evidence already published which shows that each of the three types of tubercle bacilli (bovine, human and avian) is able to cause natural tuberculosis in many different species of animals other than that which is its normal habitat.The bovine bacillus which is transmitted to animals almost exclusively by tuberculous bovines is responsible for the greater part, especially the generalised and fatal forms, of the tuberculous disease occurring naturally in farm and domestic mammals and for a not inconsiderable amount of tuberculosis in human beings.The avian bacillus whose natural host is the domestic fowl can infect casually many species of mammals, namely the pig, the ox, the sheep, the goat, the horse, the guinea-pig and the rabbit and in Zoological Gardens several marsupial species. Instances of its transmission to the different species of farm mammals are rare, except in the case of the pig, and the disease produced is usually limited and confined to the glands adjacent to the points of entry of the bacilli. This type of bacillus may however cause severe generalised and fatal disease in the pig, sheep, rabbit and marsupials.The human bacillus has a narrower range of pathogenicity than either the bovine or the avian bacillus. This type can infect the pig, the calf and the horse, but does not produce progressive tuberculosis in these species. It causes cutaneous tuberculosis in parrots and is one cause of tuberculosis in the dog and in various species of animals kept in captivity, namely the guinea-pig, monkey, gnu, antelope, peccary, etc., in which species infection is followed by generalisation and progression of the disease.The evidence accumulated regarding the susceptibility of various species of animals to the three types of tubercle bacilli under farm and domestic conditions and in captivity may be summed up as follows.All three types of bacilli can infect the ox, pig, horse, guinea-pig and rabbit.Two types of bacilli have been found in the following species; viz. bovine and avian in the sheep, the goat and Australian marsupials; bovine and human in the domestic dog and in the ape, monkey and Ungulata in captivity; human and avian in the parrot.Only one type of bacillus has so far been obtained from domestic fowls (the avian), the domestic cat, hedgehog, mink and ferret (the bovine) and members of several species in captivity.

We characterized the immunohistochemical expression profiles of dysgerminomas from a 16-y-old maned wolf and 13 domestic dogs using the following biomarkers: Sal-like protein 4 (SALL4), octamer-binding transcription factor 3/4 (OCT3/4), placental alkaline phosphatase (PLAP), c-kit, and vimentin. The maned wolf had nonspecific and long-standing clinical signs of lethargy, anorexia, and weight loss, and was euthanized because of poor prognosis. At autopsy, the left ovary was effaced by a 12 × 8 × 6 cm mass, comprised of anaplastic cells with a mitotic count of 20 mitoses in 10 high power fields. Dysgerminomas from 7 of 13 domestic dogs had nuclear expression of SALL4. Dysgerminomas from the maned wolf and 2 domestic dogs had both nuclear and cytoplasmic expression of SALL4. Cytoplasmic expression of PLAP and OCT3/4 was present in dysgerminomas from the maned wolf and 3 (PLAP) or 4 (OCT3/4) domestic dogs. All dysgerminomas expressed vimentin. Membranous c-kit expression was rare in the dysgerminoma from the maned wolf, and variable in dysgerminomas from 4 domestic dogs. A dysgerminoma from a domestic dog had cytoplasmic expression of c-kit. SALL4 is a useful marker to confirm germ cell origin of dysgerminoma in canids.

On the territory of the Republic of Buryatia, the epizootological profile is formed by 8 nosological forms of infectious pathology of farm animals. The dominant epizootic significance is rabies, leptospirosis, brucellosis. Rabies was registered in 8 (38.1 %) rural administrative districts of the republic and in the urban district of Ulan-Ude. In the total number of cases of rabies, the disease of farm animals occupies 48.3%, domestic carnivores-3.9, and in 47.6% of cases, epizootic foci began among wild animals. The main reservoir of the rabies virus is the wild fox: 46.2 % in the total number of cases and 97.1 % - in autochthonous epizootic foci. Leptospirosis in the conditions of Buryatia is an indigenous natural focal infection with a pronounced indicator of epizootic manifestation in the form of infection of animals without clinical signs. It is registered in 11 (52.4 %) rural administrative districts of the republic in 1.5 % of cattle and 0.6% of horses. The unfavorable situation with bovine brucellosis persisted from 2009 to 2018, 26 unfavorable points were registered. In the Jida district, 5 km from the state border with Mongolia, brucellosis was first registered in a dog. In this area, the corridor of migration of wild animals across the border passes, which confirms the assumption of the existence of natural foci of brucellosis in the transboundary territories of Russia and Mongolia and the introduction of the pathogen from the natural focus to the territory of the buffer zone farms.

In south-west Nigeria, several Trypanosoma species are prevalent. These parasites cause trypanosomosis in livestock and man with cellular changes and tissue damages resulting in great loss in production and sometimes death. Hence, continuous surveillance is very necessary for monitoring and control of trypanosomosis. This study concentrated on the survey of trypanosome infection and its effect on both weight and haematological indices of Nigerian cattle. One hundred and eighty cattle were used in the study. The sex of cattle was noted while the age of cattle was determined using dentition and weight was determined using weigh-band. Blood sample was collected from 180 cattle, DNA was extracted from each cattle blood sample and PCR technique was adopted as a molecular diagnostic tool for prevalence study. Reference primer specific for Trypanosoma vivax (Variant Surface Glycoprotein (VSG) gene) was used as a probe for the detection of the presence of parasite while gene amplification on argarose gel was considered positive for the cattle under consideration. The haematological analysis was also carried out using Auto-haemoanalyser. The prevalence rate of Trypanosoma vivax based on sex, age and breed of cattle was determined. The result revealed a prevalence rate of 87.22%. About 19.44% was due to infection in the males while 67.78% of the infection was recorded in the female cattle. For the prevalence within the age group; 0 -1 year was 21.11%, >1≤ 2 years was 21.11%, >2 ≤ 3 years was 32.22%, >3 years was 12.78%. There was no significant (p>0.05) difference between the weight, haematological parameters determined and the infection status. In the phase of infection, the hosts were able to maintain their red blood cell counts from a perceived compensatory response which was revealed in the erythrocycitc indices an packed cell volume. Though the prevalence rate recorded was high, the hosts were able to maintain the haematimetric indices, it can then be concluded that Muturu cattle has displayed trypanotolerant property

The Impact

Abstract Information on how wildlife is affected by pine plantation clearcutting is relevant for designing management strategies to promote biodiversity conservation in productive systems. By comparing the number of records of carnivores in a mosaic of pine plantations and native forest remnants before and after pine harvesting, we assessed the effect of plantation clearcutting on carnivore presence in ten sampling areas in Central Chile. We also included a number of covariates to account for their potential confounding effects, for example, the distance between each site and the nearesting human settlement and vegetation cover. A total of 10 species were observed, but no negative effect of clearcutting on carnivore presence was detected. Only the culpeo fox (Lycalopex culpaeus) responded positively to the harvesting of pine plantations. The threatened kodkod (Leopardus guigna) was absent in clearcut areas and the number of records increased in forests or plantations with a dense understorey. The domestic dog (Canis lupus familiaris) responded positively to human settlements and seems to prefer more open areas. The number of records for the Puma (Puma concolor) and the domestic cat (Felis silvestris catus) was too few, and hence, we could not make any inference regarding these two species. The other species recorded showed different responses to one or more of the included covariates. Although our results showed that the recording of some species could change in the short term after pine harvesting, future studies should assess the impact of clearcutting at a much higher scale, both in terms of space and time.

Congenital urethral strictures are well recognised in human beings and have recently been described in two cats but have not been previously reported in dogs. A 10-month-old female English Bull Terrier presented with a life-long history of being unable to pass a normal stream of urine. Urethrocystoscopy confirmed the presence of a stricture lesion in the proximal urethra. This thin, membranous structure was effaced under endoscopic visualisation using a 10 mm diameter balloon-dilation catheter. Complete and sustained resolution of clinical signs occurred after a single dilation procedure. To the best of our knowledge, this is the first report of a congenital urethral stricture in a dog and the term congenital obstructive proximal urethral membrane may be useful for describing these lesions in the future.

Exposure of fifteen children to mumps virus of fifth amniotic passage in chick embryos led to involvement of the salivary glands in six, orchitis in the absence of other manifestations of mumps in one, and to no signs of illness in eight. Attempts to isolate virus from the saliva of these individuals gave the following results: 1. All patients with involvement of the salivary glands excreted virus beginning on the 11th to 15th day after exposure, 2 to 6 days prior to onset of clinical signs of disease and extending up to the 4th day of illness. 2. The patient with primary orchitis without any recognized involvement of the salivary glands excreted virus for 2 days, beginning on the 15th day after exposure and 10 days prior to his illness. 3. Six of the eight children classified as having inapparent infections because of their serologic response in the absence of clinical signs of illness, began to excrete virus on the 15th to 16th day after exposure for from 1 to 9 or more days. The epidemiologic significance of these data is discussed.
