Leishmaniasis are neglected diseases caused by several species of Leishmania that affect humans and many domestic and wild animals with a worldwide distribution. The objectives of this review are to identify wild animals naturally infected with zoonotic Leishmania species as well as the organs infected, methods employed for detection and percentage of infection. A literature search starting from 1990 was performed following the PRISMA methodology and 161 reports were included. One hundred and eighty-nine species from ten orders (i.e., Carnivora, Chiroptera, Cingulata, Didelphimorphia, Diprotodontia, Lagomorpha, Eulipotyphla, Pilosa, Primates and Rodentia) were reported to be infected, and a few animals were classified only at the genus level. An exhaustive list of species; diagnostic techniques, including PCR targets; infected organs; number of animals explored and percentage of positives are presented. L. infantum infection was described in 98 wild species and L. (Viania) spp. in 52 wild animals, while L. mexicana, L. amazonensis, L. major and L. tropica were described in fewer than 32 animals each. During the last decade, intense research revealed new hosts within Chiroptera and Lagomorpha. Carnivores and rodents were the most relevant hosts for L. infantum and L. (Viannia) spp., with some species showing lesions, although in most of the studies clinical signs were not reported.

Background: Superficial fungal diseases are cosmopolitan affections caused by yeast and filamentous microscopic fungi (dermatophytes and moulds). Their very high prevalence and worldwide distribution make them one of the most common dermatological diseases. Our study aims to describe the profile of superficial fungal diseases diagnosed in Senegal and Togo and to identify the causative agents circulating in both countries. Material and Methods: This is a descriptive study carried out in Senegal and Togo, involving 602 and 135 patients respectively. The patients presenting clinical signs were screened in the Parasitology-Mycology laboratories of the Fann University Hospital in Dakar (from February 2019 to February 2020) and Sylvanus Olympio University Hospital in Lomé (from October 2019 to March 2020). Samples collected were examined using routine mycological techniques (Direct examination and culture). Results: In Senegal 293 (48.67%) out of 602 patients enrolled were diagnosed with superficial fungal diseases. Patients under 10 old years and female, most affected, represented 23.42% and 61.39% of cases respectively. The patients were seen mostly in September with 27 positives cases out of 42. Trichophyton soudanense and Candida albicans complex were the most common species, with a prevalence rate of 30.37% and 26.96% respectively. In Togo, 67.41% (91) of the 135 patients presented superficial mycosis. The female (58.76%) and the patients aged 31-40 year old (21.65%) were the most affected. Highest prevalence is recorded in October with 11 positive cases out of 13. Malassezia furfur was the most common species with a prevalence of 28.57%. The same species of fungi were found in both countries with the exception of three fungi Trichophyton violaceum, Aspergillus candidus (respectively 3 cases and 1 case in Senegal) and Trichophyton tonsurans (3 cases in Togo). Conclusion: Superficial mycoses are a frequent reason for consultation in Senegal and Togo. Dermatophytes and yeasts of the genus Candida and Malassezia are the most common agents involved. The use of innovative diagnostic techniques could allow a more precise identification of species for a better therapeutic management.

Canine distemper is a multisystemic contagious viral disease having a worldwide distribution, a high mortality rate, and significant central neurologic system (CNS) complications. In its systemic manifestations, it is often presumptively diagnosed on the basis of clinical signs and history. Few definitive antemortem diagnostic tests exist, and most are limited to the detection of viral antigen by immunofluorescence techniques on tissues or cytologic specimens or high immunoglobulin levels in CSF (cerebrospinal fluid). Diagnosis of CNS distemper is often unreliable due to the relatively low cell count in CSF (<50 cells/μl) and the binding of blocking immunoglobulins in CSF to cell surfaces. A more reliable and definitive test might be possible utilizing direct morphologic detection of the etiologic agent. Distemper is the canine equivalent of human measles, in that both involve a closely related member of the Paramyxoviridae, both produce mucosal inflammation, and may produce CNS complications. In humans, diagnosis of measles-induced subacute sclerosing panencephalitis is through negative stain identification of whole or incomplete viral particles in patient CSF.

Isolation of Leishmania parasite and species identification are important for confirmation and to help define the epidemiology of the leishmaniasis. Mice are often used to isolate pathogens, but the most common mouse strains are resistant to infection with parasites from the Leishmania (Viannia) subgenus. In this study we tested the inoculation of interferon gamma knockout (IFNγ KO) mice with biopsy macerates from Leishmania-infected patients to increase the possibility of isolating parasites. Biopsies from twenty five patients with clinical signs of leishmaniasis were taken and tested for the presence of parasites. Immunohistochemical assay (IHC) and conventional histopathology detected the parasite in 88% and 83% of the patients, respectively. Leishmania sp. were isolated in biopsy macerates from 52% of the patients by culture in Grace's insect medium, but 13% of isolates were lost due to contamination. Inoculation of macerates in IFNγ KO mice provides isolation of parasites in 31.8% of the biopsies. Most isolates belong to L. (Viannia) subgenus, as confirmed by PCR, except one that belongs to L. (Leishmania) subgenus. Our preliminary results support the use of IFNγ KO mice to improve the possibility to isolate New World Leishmania species.

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.

Abstract Background Onychomycosis is a common persistent infection of the nail unit by fungi either dermatophytes, yeasts or non-dermatophyte molds (NDMs). It is classified clinically to distal and lateral subungual onychomycosis (DLSO), superficial white onychomycosis (SWO), proximal subungual onychomycosis (PSO), candidal onychomycosis, endonyx onychomycosis and total dystrophic onychomycosis (TDO). Onychomycosis is commonly confirmed by clinical examination side by side with regular diagnostic techniques such as direct microscopy and fungal culture, which are considered the golden are considered the golden standards of diagnosis. Aim of the Work to evaluate two PDT approaches in the treatment of onychomycosis. The study will compare the effect of PDT using conventional method versus fractional CO2 assisted PDT for achievement of a clinical and mycological cure in cases of onychomycosis. Patients and Methods we conducted a right-left controlled study, on 21 patients with at least 2 toenails onychomycosis in the same patient. These patients were recruited from outpatient clinic of dermatology department at Ain Shams University Hospitals. The study was conducted during the period from December 2016 till June 2017. Twenty-one patients (4 males and 17 females) with clinical signs of toenail onychomycosis were enrolled in the study. The diagnosis was confirmed via laboratory studies. Results in our study, we found that Aspergillus species were the most common causative organisms of OM followed by and this is possibly because the non NDMs are more frequent in tropical and subtropical areas with a hot and humid climate. Conventional PDT and fractional CO2-assisted PDT have an antifungal activity as manifest by a mycological cure rate of 57.1% and 76.2% in OM cases respectively. Fractional CO2-assisted PDT was superior to conventional PDT as regard the clinical improvement in nail appearance and patient satisfaction. Conclusion non-dermatophyte molds are important and common pathogens in toenail onychomycosis. Aspergillus species play an important role as pathogens for toenail onychomycosis in Egypt.

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.

Peste des petits ruminants (PPR) is a disease of economic and veterinary importance leading to considerable economic losses. PPR affects small domestic and wild ruminants. Sheep and goats are the natural hosts of PPR but cattle, pigs, African buffaloes and camels are also affected by the PPR virus. Clinical signs seen are mainly fever, mucopurulent nasal and ocular discharges, cough, dyspnoea, gastroenteritis leading to severe diarrhoea. The post mortem lesions seen are congested lungs, congestion of gastrointestinal tract, especially the discontinuous streaks of congestion, which is referred to as Zebra stripes or Zebra markings, oedematous and congested retropharyngeal and mesenteric lymph nodes, linear haemorrhages in the intestinal mucosa and splenomegaly. PPR infection is characterized by a rise in packed cell volume (PCV), increase in haemoglobin concentration (HbC), leukopenia with lymphopenia. The serum alkaline phosphatase, alanine aminotransferase and aspartate aminotransferase activities are elevated, blood urea nitrogen and creatinine concentrations are also elevated. The disease is also characterized by disseminated intravascular coagulopathy (DIC) evidenced by prolonged prothrombin time (PT), prolonged activated thromboplastin time (APTT), thrombocytopenia, and hypofibrinogenemia. In PPR infection, serum biomarkers of oxidative stress such as vitamins A, C, E and glutathione activity decreases while serum catalase, superoxide dismutase, glutathione reductase and xanthine oxidase increase. Diagnostic techniques include histopathology, virus isolation, immunocapture enzyme-linked immunosorbent assay (icELISA), Competitive Enzyme Linked Imunnosorbent Assay (cELISA) and Combined Indirect ELISA (CI-ELISA) agar gel immunodiffusion, real-time polymerase chain reaction (RT-PCR), reverse transcription-loop mediated isothermal amplification assay (RT-LAMP), Luciferase immunoprecipitation system (LIPS) and immunohistochemistry. Therefore, this review focused on the aetiology, epidemiology, pathology, immunology, and disease status in Africa, diagnosis, control, prevention, treatment and control of this disease.

AbstractBovine torovirus (BoTV) is a pleomorphic virus with a spike-bearing envelope and a linear, non-segmented, positive-sense single-stranded RNA genome. This kidney-shaped virus is associated with diarrhea in calves and apparently has a worldwide distribution. This review provides details of the history and taxonomy of BoTV since its discovery in 1979. Information about virion morphology and architecture, antigenic and biological properties, viral genome, protein composition, thermal and chemical stability, and pH and proteolytic enzymes resistance is also summarized. A major focus of this review is to postulate a possible epidemiological cycle for BoTV, based on epidemiological data obtained in our studies and other published data, and progressing from the newborn calf to the adult animal. The distribution, host range, pathogenesis, disease and clinical signs (under experimental and natural exposure), pathology, diagnosis, prevention, treatment and control of BoTV infections are also described. In addition, a discussion of the zoonotic implications of torovirus-like particles detected in patients with gastroenteritis that resemble and cross-react with BoTV is presented. Hopefully, the findings described here will alert others to the existence of BoTV in cattle and its contribution to the diarrheal disease complex. This review also highlights the need for continual vigilance for potential zoonotic viruses belonging to the orderNidovirales, such as the SARS coronavirus.

Fourteen, 3-month-old calves were intracerebrally inoculated with the agent of chronic wasting disease (CWD) from white-tailed deer (CWDwtd) to compare the clinical signs and neuropathologic findings with those of certain other transmissible spongiform encephalopathies (TSE, prion diseases) that have been shown to be experimentally transmissible to cattle (sheep scrapie, CWD of mule deer [CWDmd], bovine spongiform encephalopathy [BSE], and transmissible mink encephalopathy). Two uninoculated calves served as controls. Within 26 months postinoculation (MPI), 12 inoculated calves had lost considerable weight and eventually became recumbent. Of the 12 inoculated calves, 11 (92%) developed clinical signs. Although spongiform encephalopathy (SE) was not observed, abnormal prion protein (PrPd) was detected by immunohistochemistry (IHC) and Western blot (WB) in central nervous system tissues. The absence of SE with presence of PrPd has also been observed when other TSE agents (scrapie and CWDmd) were similarly inoculated into cattle. The IHC and WB findings suggest that the diagnostic techniques currently used to confirm BSE would detect CWDwtd in cattle, should it occur naturally. Also, the absence of SE and a distinctive IHC pattern of CWDwtd and CWDmd in cattle suggests that it should be possible to distinguish these conditions from other TSEs that have been experimentally transmitted to cattle.
