“…This is shown graphically in Figure 2. This high autumn, low spring-ratio has also been demonstrated in the United States (Menges and Georg, 1957;Kaplan and Ivens, 19(il) and in Australia (Keep, 1963). ]<]xaminatiou of the figures presented by Marples (1951) for humau M. canis ringworms iu Dunedin over the three years 1947, 1948, 1949 shows that much the same seasonal distribution was present 20 years ago.…”

Investigations in New Zealand have shown that animals are an important reservoir of human ringworm. Of 4,328 dermatophytes recovered from human lesions over the six-year period 1963-68, 1,579 (36-5%) were considered to be of animal origin-1,254 (29-0% total) Microsporum canis; 189 (4-4% total) Trichophyton erinacei; 86 (2-0'/r total) Trichophyton mentagrophytes; 46 (1'1%) Trichophyton verrucosum; 2 Microsporum distortum and 2 Trichophyton equinum var. autotrophicum. Human infection with zoophilic dermatophytes was more pronounced in the younger age groups, showed no marked sex distribution, and usually occurred at only a single exposed site on the body. Apart from the M. canis ringworms which occurred mainly between the months February to August (autumn, winter), no marked seasonal variations were observed.Of the 12 dermatophyte species recovered from 1,290 wild, domestic and laboratory animals examined between 1960-68, only nine were regarded as possessing parasitic properties. These were the zoophilic Microsporum canis, M. distortum, M. nanum, Trichophyton erinacei, T. equinum var. autotrophicum, T. gallinae, T. mentagrophytes, T. verrucosum, and the geophilic M. gypseum. Those regarded as essentially non-pathogenic were the geophilic M. cookei, T. ajelloi and T. terrestre. Apart from T. mentagrophytes which was recovered from a wide variety of animals, the remaining pathogenic dermatophytes displayed marked host specificities. T. mentagrophytes var. quinckeanum was not isolated from any of the human or animal specimens.It is confirmed that, in New Zealand, animals form an important reservoir of human ringworm. Direct contact with small domestic pets rather than larger farm animals is the main source of ir>fection. Of the small wild animals, hedgehogs (Erinaceus europaeus) appear most important.Senior Lecturer in Microbiology, University o£ Otago,

“…The peak months for the occurrence of ringworm among cats in this survey were February and April. In a somewhat similar survey carried out in USA, Menges and Georg (1957) found that 21% of cases occurred in spring, 37% in summer, 67% in autumn and 27% in the winter. The very high April incidence of cases in the present series in this hemisphere is in accord with these findings.…”

“…Neoplastic cells consistent with lymphoma were found in the haired skin of the forearm, axilla and pelvic limbs of a female Virginia opossum (Higbie et al, 2015). The ringworm caused by T. mentagrophytes was isolated from the opossum (Menges & Georg, 1957). Ticks from genus…”

Histomorphometrical study on the skin of different regions of the Caribbean common opossum (Didelphis marsupialis Linnaeus, 1758)

Common opossums (Didelphis marsupialis) are found throughout the Caribbean island of Trinidad and Tobago. The present work was conducted on the fresh normal skin of 10 common opossums and aimed to provide morphometric data and a histological description of the skin in different regions of the body. In the examined regions, the skin presented a typical thin skin morphology, with numerous folds on the surface. The dermis–epidermis junction is smooth, without the occurrence of dermal papillae. The average thickness of the opossum epidermis was 19.5 µm. The cranial region of the back showed the greatest epidermal thickness, and together with the other areas of the back presented an epidermis 2–3 times thicker compared with the other areas examined. To further confirm that the skin changes in the opossum are age‐ or diet‐related, additional studies are required.
